Görüntüleme yöntemleri klavuzluğunda subkuran venöz port implantasyonu: Tek Merkez Deneyimi

The aim of this study is to present our experience about subcutaneous venous ports placed under guidance of imaging method. In this study, the records of interventional radiology unit were reviewed and 150 consecutive subjects, who underwent subcutaneous venous port implantation under guidance of imaging methods between the dates of 01.03.2007 and 04.09.2008 were presented. Patients were evaluated in terms of technical success, perioperative and late term complications. Thecnical success was 100%. None of the subjects had perioperative (first 30 days) complication. During long term follow-up, 3 subjects had skin necrosis and 4 subjects had infection related with catheter (2.6%). Rate of catheter sepsis calculated ad 1.3%. Complication which required extraction of port (skin necrosis, infection) occurred in 7 subjects (4.6%). One hundred and twenty one (121) of the patients are still alive and their ports are functional. Due to low rates of perioperative and early term complication, if there are qualified staff and adequate equipment, technique of subcutaneous venous port placement under guidance of imaging method should be preferred instead of landmark technique

Vitamin D Deficiency in Children and Adolescents

Objective Vitamin D deficiency is an important health problem in both developed and developing countries. Recent reports on the extraskeletal effects of vitamin D have led to increased interest in prevalence studies on states of deficiency/insufficiency of vitamin D. The aim of this study was to determine the frequency of vitamin D deficiency and insufficiency in children and adolescents residing in Ankara, Turkey and to investigate the factors associated with low vitamin D status

Experimental investigation of thermal comfort performance of a radiant wall and ceiling panel system

The number of radiant heating-cooling systems in building applications is increasing it is because of low energy consumption, low operating temperature and high values they provide in terms of working compatibility with renewable energy sources. In this study, ground source heat pump integrated radiant panels installed on the wall and suspended ceiling of the office room in Yıldız Technical University Science and Technology Application and Research Centre were experimentally examined in terms of thermal comfort according to the relevant standards. Vertical air temperature differences and mean radiant temperatures were investigated. The mean air temperature differences at 0.1 m and 1.7 m were found to be 3,9 oC 2.9 oC 3.5 oC, 3.1 oC and 3.4 oC on average for the five different stands, respectively. PMV and PPD values were found to be 0.78 and 18.9% for February 12 (Case 1), 0.36 and 8.4% for February 13 (Case 2), respectively. In the experiment carried out under the conditions of Case 2, while the comfort conditions were provided in almost all of the day, the desired comfort conditions could not be achieved in Case 1 after 11 am. © 2022.

Radiological report: Expectations of clinicians

PURPOSE Although there have been many publications on composing an accurate radiological report, they usually do not include an assessment of the clinicians expectations from a radiological report. In this study, we aimed to assess the clinicians' expectations and preferences in terms of radiology report style and content. MATERIALS AND METHODS A multiple-choice questionnaire, containing 19 questions, was formed. Two-hundreds clinicians, working either in a university hospital or a public hospital, were allocated into 4 groups which included equal number of clinicians from surgery and internal medicine departments. Questionnaire was applied to participants by face-to-face interview. Results were analyzed for each group using Pearson chi-square test. RESULTS No statistically significant difference was found among four groups except for the 16(th) question which was about the image format pertaining to the report (CD/DVD or negative film). It has been determined that clinicians preferred detailed, standardized radiological reports with complete sections (i.e., clinical information, technique, findings, conclusion, recommendations). CONCLUSION This study provided essential data for radiologists to write more effective reports

Vieussens’ arterial ring: a rare coronary variant anatomy

PURPOSEWe aimed to evaluate Vieussens’ arterial ring (VAR) variants by consecutive coronary computed tomography (CT) angiography examinations.METHODSWe retrospectively evaluated the presence of VAR in a total of 3443 consecutive coronary CT angiography examinations performed between November 2010 and January 2015. CT examinations were performed with a 64-row multidetector computed tomography (MDCT) scanner. All CT angiography images were evaluated for the presence and morphologic features of VAR subtypes. VAR variants were classified into four subgroups.RESULTSEleven VAR variations (3.19‰) were identified. Type 1A was the most common VAR type (n=8), followed by Type 2 (n=2) and Type 3 (n=1). Type 1B was not detected.CONCLUSIONAlthough VAR variation is less frequently detected with coronary CT angiography than in previously reported anatomic series, coronary CT angiography is quite effective to reveal VAR subtypes and other relevant cardiocoronary anomalies

Choosing the appropriate side for subcutaneous port catheter placement in patients with mastectomy: Ipsilateral or contralateral?

To evaluate long-term clinical follow-up results of implanting subcutaneous port catheters (SPCs) on ipsilateral or contralateral with mastectomy side in patients with axillary lymph node dissection. A total of 73 patients composed of ipsilateral (34 catheters) and contralateral (39 catheters) groups, with SPCs were included. All patients had lumpectomy or modified radical mastectomy for breast cancer. Ipsilateral and contralateral groups had similar patient characteristics. Five late complications were seen in the ipsilateral group and 2 late complications in the contralateral group. No statistical significant difference was seen between two groups in regard to late complications. Four complications of the ipsilateral group were classified as major group C and 1 as major group D, while 1 complication of the contralateral group was classified as minor group B and 1 as major group C according to Society of Interventional Radiology (SIR) classification. No statistical significant difference was seen between complication rates of two groups in regard to SIR classification. SPC related complications do not differ in regard to ipsilateral or contralateral side selection on mastectomized patients with breast cancer and lymph node dissection. SPCs can be implanted on ipsilateral or contralateral sides of the operation in these patients
