A multi-institutional experience in adventitial cystic disease
AbstractBackgroundAdventitial cystic disease (ACD) is an unusual arteriopathy; case reports and small series constitute the available literature regarding treatment. We sought to examine the presentation, contemporary management, and long-term outcomes using a multi-institutional database.MethodsUsing a standardized database, 14 institutions retrospectively collected demographics, comorbidities, presentation/symptoms, imaging, treatment, and follow-up data on consecutive patients treated for ACD during a 10-year period, using Society for Vascular Surgery reporting standards for limb ischemia. Univariate and multivariate analyses were performed comparing treatment methods and factors associated with recurrent intervention. Life-table analysis was performed to estimate the freedom from reintervention in comparing the various treatment modalities.ResultsForty-seven patients (32 men, 15 women; mean age, 43 years) were identified with ACD involving the popliteal artery (n = 41), radial artery (n = 3), superficial/common femoral artery (n = 2), and common femoral vein (n = 1). Lower extremity claudication was seen in 93% of ACD of the leg arteries, whereas patients with upper extremity ACD had hand or arm pain. Preoperative diagnosis was made in 88% of patients, primarily using cross-sectional imaging of the lower extremity; mean lower extremity ankle-brachial index was 0.71 in the affected limb. Forty-one patients with lower extremity ACD underwent operative repair (resection with interposition graft, 21 patients; cyst resection, 13 patients; cyst resection with bypass graft, 5 patients; cyst resection with patch, 2 patients). Two patients with upper extremity ACD underwent cyst drainage without resection or arterial reconstruction. Complications, including graft infection, thrombosis, hematoma, and wound dehiscence, occurred in 12% of patients. Mean lower extremity ankle-brachial index at 3 months postoperatively improved to 1.07 (P < .001), with an overall mean follow-up of 20 months (range, 0.33-9 years). Eight patients (18%) with lower extremity arterial ACD required reintervention (redo cyst resection, one; thrombectomy, three; redo bypass, one; balloon angioplasty, three) after a mean of 70 days with symptom relief in 88%. Lower extremity patients who underwent cyst resection and interposition or bypass graft were less likely to require reintervention (P = .04). One patient with lower extremity ACD required an above-knee amputation for extensive tissue loss.ConclusionsThis multi-institutional, contemporary experience of ACD examines the treatment and outcomes of ACD. The majority of patients can be identified preoperatively; surgical repair, consisting of cyst excision with arterial reconstruction or bypass alone, provides the best long-term symptomatic relief and reduced need for intervention to maintain patency

Population-based Assessment of Aortic-related Outcomes in Aortic Dissection, Intramural Hematoma, and Penetrating Aortic Ulcer
BACKGROUND: The aim of the study was to analyze aortic-related outcomes after diagnosis of aortic dissection (AD), intramural hematoma (IMH), and penetrating aortic ulcer (PAU) from a population-based approach. METHODS: Retrospective review of an incident cohort of AD, IMH, and PAU patients in Olmsted County, Minnesota from 1995 to 2015. Primary end point was aortic death. Secondary end points were subsequent aortic events (aortic intervention, new dissection, or rupture not present at presentation) and first-time diagnosis of an aortic aneurysm. Outcomes were compared with randomly selected population referents matched for age and sex in a 3:1 ratio using Cox proportional hazards regression adjusting for comorbidities. RESULTS: Among 133 patients (77 AD, 21 IMH, and 35 PAU), 57% were males, and mean age was 71.8 years (standard deviation, 14). Median follow-up was 10 years. Of 73 deaths among AD/IMH/PAU patients, 23 (32%) were aortic-related. Estimated freedom from aortic death was 84%, 80%, and 77% at 5, 10, and 15 years. There were no aortic deaths among population referents (adjusted hazard ratio [HR] for aortic death in AD/IMH/PAU, 184.7; 95% confidence interval [95% CI], 10.3–3,299.2; P < 0.001). Fifty (38%) AD/IMH/PAU patients had a subsequent aortic event (aortic intervention, new dissection, or rupture), whereas there were 8 (2%) aortic events among population referents (all elective aneurysm repairs; adjusted HR for any aortic event and aortic intervention in AD/IMH/PAU patients, 33.3; 95% CI, 15.3–72.0; P < 0.001 and 31.5; 95% CI, 14.5–68.4; P < 0.001, respectively). After excluding aortic events/interventions 14 days of diagnosis, AD/IMH/PAU patients remained at increased risk of any aortic event (adjusted HR, 10.8; 95% CI, 3.9–29.8; P < 0.001) and aortic intervention (adjusted HR, 9.6; 95% CI, 3.4–26.8; P < 0.001). Among those subjects with available follow-up imaging, the risk of first-time diagnosis of aortic aneurysm was significantly increased for AD/IMH/PAU patients when compared with population referents (adjusted HR, 10.9; 95% CI, 5.4–21.7; P < 0.001 and 8.3; 95% CI, 4.1–16.7; P < 0.001 for thoracic and abdominal aneurysms, respectively) and remained increased when excluding aneurysms that formed within 14 days of AD/IMH/PAU (adjusted HR, 6.2; 95% CI, 1.8–21.1; P = 0.004 and 2.8; 95% CI, 1.0–7.6; P = 0.040 for thoracic and abdominal aneurysms, respectively). CONCLUSIONS: AD/IMH/PAU patients have a substantial risk of aortic death, any aortic event, aortic intervention, and first-time diagnosis of aortic aneurysm that persists even when the acute phase (≤14 days after diagnosis) is uncomplicated. Advances in postdiagnosis treatment are necessary to improve the prognosis in these patients
Effect of Aortic Angulation on the Outcomes of Fenestrated-Branched Endovascular Aneurysm Repair
Burden and causes of readmissions following initial discharge after aortic syndromes
Abstract
Introduction: Aortic syndromes (AS), including aortic dissection (AD), intramural hematoma (IMH), and penetrating aortic ulcer (PAU), carry significant morbidity and mortality; little data exist regarding burden and causes of related rehospitalizations following initial discharge.
Methods: The study was conducted using the Rochester Epidemiology Project (REP). All adult residents (age≥18 years) with an incident diagnosis of AD/IMH/PAU (1995-2015) were identified from the REP using the International Classification of Disease (ICD), 9th and 10th revision, codes and Hospital Adaptation of the ICD, 2nd edition, codes. Assessment of any-cause (aortic+cardiovascular), aortic-related, or cardiovascular-related readmissions was determined following date of hospital discharge or diagnosis date (i.e. the index event).
Results: A total of 117 patients out of 130 cases of AD/IMH/PAU included in the initial study population survived the index event and were evaluated. The median age of diagnosis was 74 years and 70 (60%) were male. A total of 79 patients (68%) experienced at least one readmission. The median time to first any-cause, cardiovascular and aortic readmission was 143, 861 and 171 days, respectively. The cumulative incidence of any-cause readmissions at 2, 4 and 10 years was 45%, 55% and 69%, respectively. The cumulative incidence of cardiovascular readmissions at 2, 4 and 10 years was 15%, 20% and 28%, respectively. The cumulative incidence of aortic readmissions at 2, 4 and 10 years was 38%, 46% and 59%, respectively. Overall survival for the entire cohort at 2, 4 and 10 years was 84%, 75% and 50%, respectively.
Conclusion: Readmissions following initial discharge after diagnosis of AS are common and not different across specific disease types. While aortic-related rehospitalization occur in more than half of patients but tend to be earlier, cardiovascular-related rehospitalizations tend to happen later in about one third of subjects. This may suggest the need for early follow-up focused on aortic complications while later follow-up should address cardiovascular events
Impact of patient factors and procedure on readmission after aortic dissection admission in the states of Florida and New York
Background: Readmissions after aortic dissection (AD) admission are not well described. Using state-based administrative claims data, we sought to define readmission rates after AD and to identify factors associated with them.
Methods: State Inpatient Databases for Florida (2007-2012) and New York (2008-2012) were queried for AD index admissions. Admissions were stratified by initial treatment strategy: type A open surgery repair (TAOR), type B open surgery repair (TBOR), thoracic endovascular aortic repair (TEVAR), or medical management (MM). All-cause readmission rates were calculated at 30 days, 90 days, and 2 years. Logistic regression was used to identify factors associated with readmission at each time point for all type A admissions (TAOR) or type B admissions (TBOR, TEVAR, MM).
Results: We identified 4670 patients with an AD index admission. Treatment was with TAOR in 1031 (22%), TBOR in 761 (16%), TEVAR in 412 (9%), and MM in 2466 (53%). Patients were predominantly male (59.4%) and white (61.9%), with a median age of 66 years. Overall mortality during AD index admission was 14.8% (TAOR, 15.8%; TBOR, 17.1%; TEVAR, 9.0%; MM, 14.7%; P = .002 across all groups). All-cause readmission rates were similar across treatment groups at 30 days (9.6%-11%; P = .56), 90 days (15.2%-20%; P = .26), and 2 years (49.2%-54.4%; P = .15). Higher income quartile (vs lowest) was associated with lower odds of early readmission (at 30 days and 90 days) after type B admissions but not after type A admissions. At 2 years, self-pay (vs Medicare) was associated with lower odds of readmission in both type A and type B admissions, whereas higher comorbidity count and black race (vs white) were associated with higher odds of readmission. TEVAR (vs MM) was also associated with higher odds of readmission. Cardiovascular disease was the most common cause for readmission at all time points. Emergency department readmission counts were highest after MM admissions, and ambulatory surgical admissions were highest after TBOR. Both TEVAR and MM initial costs were lower than TAOR and TBOR costs, but at 2 years, costs remained significantly lower only for MM.
Conclusions: In-state 30-day, 90-day, and 2-year readmission rates after AD were not associated with initial treatment type. Two-year readmissions are common. Strategies to target socioeconomic, race, and geographic factors may reduce variations in readmission patterns after AD admission
