Effect of Significant Coronary Artery Stenosis on Prognosis in Patients with Vasospastic Angina: A Propensity Score-Matched Analysis

Vasospastic angina (VA) is a functional disease of the coronary artery and occurs in an angiographically normal coronary artery. However, it may also occur with coronary artery stenosis. We investigated the effect of coronary artery stenosis on clinical outcomes in VA patients. Study data were obtained from a prospective multicenter registry that included patients who had symptoms of VA. Patients were classified into two groups according to presence of significant coronary artery stenosis. Among 1920 patients with VA, 189 patients were classified in the "significant stenosis" group. The one-year composite clinical events rate was significantly higher in the significant stenosis group than in the "no significant stenosis" group (5.8% vs. 1.4%, respectively; p < 0.001). Additionally, the prevalence of ACS was significantly greater in the "significant stenosis" group (4.8% vs. 0.9%, respectively; p < 0.001). After propensity score matching, the adverse effects of significant stenosis remained. In addition, significant stenosis was independently associated with a 6.67-fold increased risk of ACS in VA patients. In conclusion, significant coronary artery stenosis can increase the adverse clinical outcomes in VA patients at long-term follow-up. Clinicians should manage traditional risk factors associated with atherosclerosis and control vasospasm as well as reduce the burden of atherosclerosis.ope

Smoking may be more harmful to vasospastic angina patients who take antiplatelet agents due to the interaction: Results of Korean prospective multi-center cohort

Background: The interaction between smoking and the use of antiplatelet agents on the prognosis of vasospastic angina (VA) is rarely investigated. Methods: VA-Korea is a nation-wide multi-center registry with prospective design (n = 1812). The primary endpoint was the composite occurrence of acute coronary syndrome (ACS), symptomatic arrhythmia, and cardiac death. Log-rank test and Cox proportional hazard model were for statistical analysis. Also, we conducted interaction analysis in both additive and multiplicative scales between smoking and antiplatelet agents among VA patients. For additive scale interaction, relative excess risk due to interaction (RERI) was calculated and for multiplicative scale interaction, the ratio of hazard ratio (HR) was calculated. All statistical analysis conducted by Stata Ver 16.1. Results: Patients who were smoking and using antiplatelet agents had the highest incidence rate in the primary composite outcome. The incidence rate was 3.49 per 1,000 person-month (95% CI: 2.30-5.30, log-rank test for primary outcome p = 0.017) and HR of smoking and using antiplatelet agents was 1.66 (95%CI: 0.98-2.81). The adjusted RERI of smoking and using antiplatelet agents was 1.10 (p = 0.009), and the adjusted ratio of HR of smoking and using antiplatelet agents was 3.32 (p = 0.019). The current study observed the interaction between smoking and using antiplatelet agents in both additive and multiplicative scales. Conclusions: Smoking was associated with higher rates of unfavorable clinical outcomes among VA patients taking antiplatelet agents. This suggested that VA patients, especially those using antiplatelet agents should quit smoking.ope

Differential progression of coronary atherosclerosis according to plaque composition: a cluster analysis of PARADIGM registry data

Patient-specific phenotyping of coronary atherosclerosis would facilitate personalized risk assessment and preventive treatment. We explored whether unsupervised cluster analysis can categorize patients with coronary atherosclerosis according to their plaque composition, and determined how these differing plaque composition profiles impact plaque progression. Patients with coronary atherosclerotic plaque (n = 947; median age, 62 years; 59% male) were enrolled from a prospective multi-national registry of consecutive patients who underwent serial coronary computed tomography angiography (median inter-scan duration, 3.3 years). K-means clustering applied to the percent volume of each plaque component and identified 4 clusters of patients with distinct plaque composition. Cluster 1 (n = 52), which comprised mainly fibro-fatty plaque with a significant necrotic core (median, 55.7% and 16.0% of the total plaque volume, respectively), showed the least total plaque volume (PV) progression (+ 23.3 mm3), with necrotic core and fibro-fatty PV regression (- 5.7 mm3 and - 5.6 mm3, respectively). Cluster 2 (n = 219), which contained largely fibro-fatty (39.2%) and fibrous plaque (46.8%), showed fibro-fatty PV regression (- 2.4 mm3). Cluster 3 (n = 376), which comprised mostly fibrous (62.7%) and calcified plaque (23.6%), showed increasingly prominent calcified PV progression (+ 21.4 mm3). Cluster 4 (n = 300), which comprised mostly calcified plaque (58.7%), demonstrated the greatest total PV increase (+ 50.7mm3), predominantly increasing in calcified PV (+ 35.9 mm3). Multivariable analysis showed higher risk for plaque progression in Clusters 3 and 4, and higher risk for adverse cardiac events in Clusters 2, 3, and 4 compared to that in Cluster 1. Unsupervised clustering algorithms may uniquely characterize patient phenotypes with varied atherosclerotic plaque profiles, yielding distinct patterns of progressive disease and outcome.ope

민관협력 노동센터 사례를 중심으로

학위논문(석사) -- 서울대학교대학원 : 사회과학대학 사회복지학과, 2023. 2. 김수영.The problem of non-standard workers is a major social problem. The institutions that have been designed around full-time employment relationships are fissured and do not cover non-standard workers, and the labor movement represented by trade unions is also facing a crisis around the world. With the increase in the number of non-standard workers who are not double-inclusive in both institutions and trade unions, the problem of non-standard workers has become one of the social problems that need urgent resolution in modern society. This work focuses on the fact that the worker center, which has recently made significant achievements in representing the interests of non-standard workers, is an example of the institutionalization of labor movements. This study attempts to shed light on both the subversive aspects of the worker center despite institutionalization, and the subsequent limitations that also resulted for the worker center. There are two research questions. First, this study attempts to clarify whether worker centers seek resistance after institutionalization and what their resistance patterns in the event that they resist. Next, this study also tries to clarify whether worker centers pursue organizing after institutionalization, and in what ways. In order to answer the above research question, this study reviewed literature data on the worker center, and collected key data through in-depth interviews with 20 worker center leaders and practitioners. This study analyzed the resistance of the worker center through three aspects: 'captured resistance', 'strategic resistance', and 'infrapolitics'. This study examined the organizing of non-standard workers in the worker center into three processes: 'organizing method', 'organizing process', and local collective bargaining after organizing'. This study recognizes the aim of worker centers, which was to achieve an improvement in non-standard employment and labor conditions, whilst protecting non-regular workers' human rights and expanding social welfare. However, this study revealed the existence of institutional and structural restrictions such as 'public-private partnership, 'formalizing local governments' non-standard workers organizing policy', and 'converting trade unions activities to meet the non-standard labor environment to achieve worker centers aims. This study has the following theoretical implications. First, the resistance and organizing aspects of the worker center identified in this study are significant in that it highlighted that social movement organizations can be subversive even after institutionalization, which previous studies have left as areas of 'possibility'. Second, the invisible resistance and organizing of worker centers tracked by this study are significant in that it revealed worker centers can be effective actors in the collective interest representation of non-standard workers, such as organizing workers or improving institutions. Third, this study is meaningful in that researchers who study social policy changes focusing on equality and democracy can expand their understanding of social policy continuity and adapt by paying more attention to social policy itself as well as actors including social movements. Simultaneously, this study is also an invitation to policymakers, worker center activists, trade union activists. First, it was intended to shed light on the effectiveness of a network approach for policymakers to work together with various actors, including civil society and the market, to define problems and seek solutions beyond the design and execution of the government's one-sided approach. Second, for worker center activists, this study was intended to serve as a starting point in seeking greater change, by connecting experiences from different regions as 'languages', to facilitate a discussion. Third, for trade union activists, the study was intended to highlight one of the ways in which trade unions can expand resources and capabilities of the labor movement. Namely, implementing strategic collaboration within the worker centers.비정규직 문제는 주요한 사회문제다. 정규직 고용관계 중심으로 설계되어 왔던 제도들은 고용관계가 다변화되며 비정규직 노동자들을 오롯이 포괄하지 못하며, 노동조합으로 대표되는 노동운동도 전 세계적으로 위기에 직면해있다. 제도와 노동조합 모두에 있어 이중적으로 포괄되지 않는 비정규직 노동자들이 증가함에 따라, 비정규직 문제는 현대 사회에서 시급한 해결이 필요한 사회문제 중 하나가 되었다. 본 작업은 최근 비정규직 노동자 이해대변에 있어 유의미한 성과들을 거두고 있는 민관협력 노동센터가 노동운동이 제도화된 사례라는 점에 주목하고, 민관협력 노동센터들이 제도화 이후 겪는 제약과, 제도화에도 불구하고 운동성을 유지하고 있는 지점들을 입체적으로 조명하려는 시도이다. 연구 질문은 두 가지다. 먼저, 민관협력 노동센터가 제도화 이후 저항을 추구하는지, 추구한다면 이들의 저항 양상은 어떠한 모습으로 나타나는지 밝히고자 했다. 다음으로, 민관협력 노동센터가 제도화 이후 조직화를 추구하는지, 추구한다면 이들의 조직화는 어떠한 양태들로 이뤄지고 있는지 밝히고자 했다. 위 연구 질문에 답하기 위해, 본 연구는 민관협력 노동센터에 관한 문헌 자료들을 검토하고, 노동센터 센터장 및 실무자 20명을 심층 면접하여 핵심 자료들을 수집하였다. 본 연구는 민관협력 노동센터의 저항 양상을 포획된 저항, 전략적 저항, 하부정치 세 가지 양상으로 나누어 분석하고, 민관협력 노동센터의 비정규직 노동자 조직화 추진 양상을 조직화 방법, 조직화 과정, 조직화 그 이후, 교섭의 장 세 가지 과정으로 나누어 살펴보았다. 연구결과를 바탕으로, 본 연구는 노동센터 운동이 제도화를 통해 본디 이루려고 했던 목표인 비정규직 고용‧노동 조건 개선, 비정규직 노동인권보호와 이해대변, 사회복지 확충 등을 달성하기에는 민간위탁 형태, 지방정부의 비정규직 노동자 조직화 사업 공식화 도모, 비정규직 노동자의 노동환경에 부합하도록 기존 노동조합의 활동방식 변환 추동, 조직화 이후 노동환경 개선을 이끌어 낼 수 있는 지역적 교섭의 장 마련 등 여러 제도적‧구조적 난관이 엄존하고 있음을 드러내고자 했다. 본 연구는 다음과 같은 이론적 함의를 갖는다. 첫째, 본 연구가 포착한 민관협력 노동센터의 저항과 조직화 양상들은 선행연구들이 가능성의 영역으로 남겨두었던, 사회운동조직이 제도와의 접합 이후에도 운동성을 견지할 수 있는 지점들을 실증하고, 사회운동조직의 제도화가 단순한 포섭이나 온건화로 귀결된다고 접근하는 일련의 비판들이 낡은 문제제기일 수 있음을 조명했다는 점에서 의의를 가진다. 둘째, 본 연구가 추적한 민관협력 노동센터의 비가시적 저항과 조직화 양상은, 민관협력 노동센터가 임금체불이나 부당해고 시정 등 개인적 이해대변뿐만 아니라 노동자 조직화나 제도 개선 등 비정규직 노동자의 집단적 이해대변에 있어서도 유효한 행위자가 될 수 있음을 드러냈다는 점에서 의의를 지닌다. 셋째, 본 연구는 평등 및 민주주의에 초점을 둔 사회정책 변화를 연구하는 연구자들이 사회정책 그 자체뿐만 아니라 사회운동을 비롯한 행위자에 보다 주목함으로써 사회정책의 지속과 변화에 대한 이해의 폭을 확장시킬 수 있음을 드러냈다는 점에서 의의를 지닌다. 본 연구는 사회정책 입안자, 민관협력 노동센터 상근자, 노동조합 활동가, 세 청중에게 말을 걸며 보내는 초대장이기도 하다. 첫째, 사회정책 입안자에게는 정부 일변도의 제도 설계 및 집행을 넘어 시민사회와 시장 등 다양한 행위자들과 상호 협력하며 문제를 규정하고 해결책을 모색하는 네트워크적 접근이 유효할 수 있음을 조명하고자 했다. 둘째, 민관협력 노동센터 상근자에게는 서로 다른 지역에서 겪는 경험들을 언어로서 이음으로써 더 나은 변화를 모색하는 데 출발점이 되고자 했다. 셋째, 노동조합 활동가들에게는 노동운동의 자원과 역량을 확충할 수 있는 방안 중 하나가 민관협력 노동센터와의 전략적 협업이 될 수 있음을 드러내고자 했다.제 1 장 들어가며 1 제 2 장 배경: 노동센터 운동의 등장 및 특징 6 제 1 절 한국의 비정규직과 비정규 노동운동 6 1.1. 한국의 비정규직 6 1.2. 행위자로서 비정규 노동운동 10 제 2 절 노동센터 운동의 발전 과정 12 2.1. 노동센터 운동의 등장 12 2.2. 노동운동의 제도화: 민관협력 노동센터의 성장 15 제 3 절 민관협력 노동센터 현황 및 특징 20 3.1. 민관협력 노동센터 현황 20 3.2. 민관협력 노동센터 주요 사업 22 3.3. 민관협력 노동센터 주요 특징 26 제 3 장 이론적 분석틀 29 제 1 절 사회운동과 사회운동조직의 제도화 29 1.1. 사회운동의 정체성과 역할 29 1.2. 사회운동조직의 제도화의 정의 32 제 2 절 사회운동조직의 제도화를 바라보는 상이한 이론적 관점 34 2.1. 사회운동조직의 제도화를 바라보는 이론적 관점 ① 포섭 34 2.2. 사회운동조직의 제도화를 바라보는 이론적 관점 ② 운동성 유지 36 제 4 장 연구방법 40 제 1 절 연구자의 위치 40 제 2 절 자료수집 및 분석방법 41 2.1. 자료수집방법 41 2.2. 자료분석방법 46 제 3 절 연구의 윤리적 고려사항: 사전 동의와 기밀 유지 47 제 5 장 민관협력 노동센터의 저항 양상 49 제 1 절 포획된 저항 49 1.1. 민관협력 노동센터 수탁 계기: 강요된 선택과 능동적 선택 사이 49 1.2. 민관협력으로 나아가지 못한 민간위탁: 민간위탁형태에 따른 제약 52 제 2 절 전략적 저항 60 2.1. 민간위탁형태를 역이용하기 60 2.2. 관(官)의 관습에 도전하는 실천들 62 ① 민관협력 노동센터의 정체성 투쟁 62 ② 지방의회를 통한 우회 저항 65 ③ 지역사회 네트워크를 통한 우회 저항 67 제 3 절 하부정치 69 3.1. 저항의 토대 조성 69 ① 지역노동단체 네트워크 구축 69 ② 지역시민사회단체 네트워크 구축 72 ③ 청소년 노동인권교육 강사단 양성 75 3.2. 민관협력 노동센터의 네트워크 구축과 저항의 순환고리 79 제 6 장 민관협력 노동센터의 조직화 양상 81 제 1 절 조직화 방법 81 1.1. 민관협력 노동센터 주도 조직화의 한계 81 ① 민관협력 노동센터 측면의 한계 81 ② 민관협력 노동센터와 노동조합 간 협업의 어려움 84 1.2. 수면 아래 조직화 방법 87 ① 실태조사를 통한 조직화 방법 87 ② 자조모임을 통한 조직화 방법 90 ③ 사업주를 통한 조직화 방법 93 1.3. 조직화를 수면 위로 95 ① 조직화 사업 공식화 및 예산 배정 95 ② 조직화 사업의 공식화에 따른 역설? 98 제 2 절 조직화 과정 103 2.1. 아파트 경비노동자 조직화 과정 103 2.2. 어느 형태로 조직화할 것인가? 106 ① 노동조합 형태로 조직화할 것인가? 협회 형태로 조직화할 것인가? 106 ② 노동조합 형태로 조직화하기 110 ③ 협회 또는 센터 내 자조모임으로 조직화하기 116 2.3. 경비노동자 조직화 과정에 대한 내부 성찰 118 제 3 절 조직화 그 이후, 교섭의 장 122 3.1. 사업장 교섭을 넘어선 지역별 교섭의 장: 시도 그리고 교착 122 3.2. 조직화에 기반하지 못한 이해대변의 한계: 전국단위 상생협약 체결과정 127 3.3. 실마리?: 지역기반 민관협력 노동센터의 실험들 134 제 7 장 나가며 137 제 1 절 연구결과 요약 137 제 2 절 연구의 함의 142 2.1. 연구의 이론적 함의 142 2.2. 연구의 정책적‧실천적 함의 145 제 3 절 연구의 한계 148 참 고 문 헌 149 Abstract 164석

Nitrates vs. Other Types of Vasodilators and Clinical Outcomes in Patients with Vasospastic Angina: A Propensity Score-Matched Analysis

Although vasodilators are widely used in patients with vasospastic angina (VA), few studies have compared the long-term prognostic effects of different types of vasodilators. We investigated the long-term effects of vasodilators on clinical outcomes in VA patients according to the type of vasodilator used. Study data were obtained from a prospective multicenter registry that included patients who had symptoms suggestive of VA. Patients were classified into two groups according to use of nitrates (n = 239) or other vasodilators (n = 809) at discharge. The composite clinical events rate, including acute coronary syndrome (ACS), cardiac death, new-onset arrhythmia (including ventricular tachycardia and ventricular fibrillation), and atrioventricular block, was significantly higher in the nitrates group (5.3% vs. 2.2%, p = 0.026) during one year of follow-up. Specifically, the prevalence of ACS was significantly more frequent in the nitrates group (4.3% vs. 1.5%, p = 0.024). After propensity score matching, the adverse effects of nitrates remained. In addition, the use of nitrates at discharge was independently associated with a 2.69-fold increased risk of ACS in VA patients. In conclusion, using nitrates as a vasodilator at discharge can increase the adverse clinical outcomes in VA patients at one year of follow-up. Clinicians need to be aware of the prognostic value and consider prescribing other vasodilators.ope

Association of Early Hysterectomy With Risk of Cardiovascular Disease in Korean Women

Importance: Women who undergo surgical hysterectomy before natural menopause may have an earlier increase in hematocrit and storage iron levels than those who continue menstruation, thereby increasing the risk of cardiovascular disease (CVD) at ages younger than usually seen. Examining this issue may provide important implications for women's cardiovascular health to both physicians and patients. Objective: To evaluate the association of hysterectomy with the risk of incident CVD among women before age 50 years. Design, setting, and participants: In this Korean population-based cohort study, 135 575 women aged 40 to 49 years were evaluated from January 1, 2011, to December 31, 2014. After propensity score matching in covariates including age, socioeconomic status, region, Charlson Comorbidity Index, hypertension, diabetes, dyslipidemia, menopause, menopausal hormone therapy, and adnexal surgery before inclusion, 55 539 pairs were included in the hysterectomy and nonhysterectomy groups. Participants were followed up until December 31, 2020. Data analysis was conducted from December 20, 2021, to February 17, 2022. Main outcomes and measures: The primary outcome was an incidental CVD, a composite of myocardial infarction, coronary artery revascularization, and stroke. The individual components of the primary outcome were also evaluated. Results: A total of 55 539 pairs were included; median age in the combined groups was 45 (IQR, 42-47) years. During median follow-up periods in the hysterectomy group of 7.9 (IQR, 6.8-8.9) years and nonhysterectomy group of 7.9 (IQR, 6.8-8.8) years, the incidence of CVD was 115 per 100 000 person-years for the hysterectomy group and 96 per 100 000 person-years for the nonhysterectomy group. After adjusting for confounding factors, the hysterectomy group had an increased risk of CVD compared with the nonhysterectomy group (hazard ratio [HR], 1.25; 95% CI, 1.09-1.44). The incidences of myocardial infarction and coronary artery revascularization were comparable between the groups, whereas the risk of stroke was significantly higher in the hysterectomy group (HR, 1.31; 95% CI, 1.12-1.53). Even after excluding women who underwent oophorectomy, the hysterectomy group had higher risks of CVD (HR, 1.24; 95% CI, 1.06-1.44). Conclusions and relevance: The findings of this cohort study suggest early menopause owing to hysterectomy was associated with increased risks for a composite of CVD, particularly stroke.ope

Effect of Blood Donation on the Donor’s Hemorheological Properties

The circulatory system is closely related to the inter-relationship between the anatomy of the heart and blood vessels, and the fluid dynamic properties of blood. The physical properties of blood, which affect blood flow, are called hemorheologic factors. Hemorheologic factors, such as blood viscosity and erythrocyte aggregation, are influenced mainly by hematocrit. A higher hematocrit level results in an increase in blood viscosity, erythrocyte aggregation, which impedes the circulation itself, and tissue oxygenation. An excess of serum ferritin causes injury to vascular endothelial cells and erythrocytes via oxygen free radicals. In addition, an excess of blood can aggravatee the adverse effects of the hemorheologic parameters and induce atherogenesis, microcirculatory disturbances, and major cardiovascular events. A preventive and therapeutic approach with a phlebotomy or blood donation has been stimulated by the knowledge that blood loss, such as regular donations, is associated with significant decreases in key hemorheologic variables, including blood viscosity, erythrocyte aggregation, hematocrit, and fibrinogen. Major cardiovascular events have been improved in regular blood donors by improving blood flow and microcirculation by decreasing the level of oxidative stress, improving the hemorheologic parameters, and reducing the serum ferritin level. Confirmation of the positive preventive and therapeutic effects of blood donations on cardiovascular disease by a well-designed and well-controlled Cohort study may be good news to patients with cardiovascular disease or at risk of these diseases, as well as patients who require a transfusion.ope

Computational fluid dynamics in cardiovascular disease

Computational fluid dynamics (CFD) is a mechanical engineering field for analyzing fluid flow, heat transfer, and associated phenomena, using computer-based simulation. CFD is a widely adopted methodology for solving complex problems in many modern engineering fields. The merit of CFD is developing new and improved devices and system designs, and optimization is conducted on existing equipment through computational simulations, resulting in enhanced efficiency and lower operating costs. However, in the biomedical field, CFD is still emerging. The main reason why CFD in the biomedical field has lagged behind is the tremendous complexity of human body fluid behavior. Recently, CFD biomedical research is more accessible, because high performance hardware and software are easily available with advances in computer science. All CFD processes contain three main components to provide useful information, such as pre-processing, solving mathematical equations, and post-processing. Initial accurate geometric modeling and boundary conditions are essential to achieve adequate results. Medical imaging, such as ultrasound imaging, computed tomography, and magnetic resonance imaging can be used for modeling, and Doppler ultrasound, pressure wire, and non-invasive pressure measurements are used for flow velocity and pressure as a boundary condition. Many simulations and clinical results have been used to study congenital heart disease, heart failure, ventricle function, aortic disease, and carotid and intra-cranial cerebrovascular diseases. With decreasing hardware costs and rapid computing times, researchers and medical scientists may increasingly use this reliable CFD tool to deliver accurate results. A realistic, multidisciplinary approach is essential to accomplish these tasks. Indefinite collaborations between mechanical engineers and clinical and medical scientists are essential. CFD may be an important methodology to understand the pathophysiology of the development and progression of disease and for establishing and creating treatment modalities in the cardiovascular field.ope

Prevalence of and Risk Factors for Diseases in Korean Americans and Native Koreans Undergoing Health Checkup

BACKGROUND: Korean Americans constitute the fifth largest subgroup in the Asian American population. Despite their increasing population, research and guidelines regarding their health status assessment and disease screening are lacking. This study aimed to compare the prevalence of diseases in Korean Americans and native Koreans to determine the risk factors and guidelines for disease screening. METHODS: Patients who visited the Gangnam Severance Hospital from February 2010 to May 2015 for a health checkup were enrolled in this study. Baseline characteristics, laboratory data, and the organs (stomach, colon, thyroid, brain, prostate, lung, liver, kidney, pancreas, adrenal gland, and heart) of patients were examined. Data regarding patients' dietary patterns were also obtained. Overall, 1,514 Korean Americans (group 1) and 1,514 native Koreans (group 2) were enrolled. RESULTS: The following diseases were more prevalent in group 1 than in group 2: reflux esophagitis (12.9% vs. 10%), gastric ulcer (3.0% vs. 5.5%), colorectal polyp (37.7% vs. 28.7%), hemorrhoids (32.2% vs. 29.9%), and benign prostatic hyperplasia (30.2% vs. 14.3%). Although not statistically significant, coronary artery disease has a high prevalence rate of >20% in both groups. Dietary patterns were not significant between the two groups. CONCLUSION: This study showed that the prevalence of several diseases in Korean Americans differed from that observed in native Koreans. Therefore, a foundation for setting up new guidelines for disease screening among Korean Americans is established.ope

이동된 중심정맥도관으로 인한 간헐적 심계항진 환자의 경피적 도관 제거

The totally implantable venous port device is used in patients undergoing chemotherapy. The complications associated with this device include venous thrombosis, infection, catheter fracture, extravasation, and intravascular dislodgement. The incidence of port catheter dislodgement is low. The treatment of choice for port dislocation involves immediate retrieval of the distal migrated part, and percutaneous transcatheter retrieval is regarded as the standard method. A 40-year-old female presented with intermittent palpitation. She was referred from the Department of General Surgery after detection of a fractured and dislocated implantable venous port system into the main pulmonary artery. We successfully retrieved the dislocated fractured device using a -Fr pigtail catheter and snare catheter. We herein report this case with a literature review.ope
