(2014) Coskun, Isa; Colkesen, Yucel; Demirturk, Orhan Saim; Tunel, Huseyin Ali; Turkoz, Riza; Gulcan, Oner; 24512396
We retrospectively compared the results of conventional coronary artery bypass grafting (CABG) performed on patients who showed no preoperative evidence of serious atherosclerosis of the ascending aorta with the results of the aortic no-touch technique (using coronary artery-saphenous vein composite grafts) on CABG patients who did show such evidence. From 2003 through 2012, 3,152 consecutive patients underwent isolated primary CABG at our hospital. We chose 360 for the current study. The study group (n=120) comprised patients who had undergone operation via the aortic no-touch technique. Propensity-score-matching (1: 2) was used to select the control group of 240 patients who had undergone conventional CABG. Early and late survival rates, reintervention-free survival rates, and freedom from cardiac death were compared. Early and late mortality rates were similar in the study and control groups (P=0.19 vs P=0.29, respectively), as were cardiac-related death (2.5% vs 2.1%, respectively; P=0.53) and overall death (8.3% vs 7.9%, respectively; P=0.51). Overall survival rates were 91.7% vs 92.1% and freedom-from-cardiac-death rates were 97.4% vs 97.5% (P=0.71 vs P=0.78, respectively; mean follow-up period, 5.27 +/- 2.51 yr). Reintervention-free survival rates were also similar (96.7% vs 98.8%, respectively; P=0.2). As a result of the similar rates of early and late survival, reintervention-free survival, and freedom from cardiac death, we conclude that the aortic no-touch technique with composite grafts might be a reasonable option in patients who have atherosclerotic ascending aorta that cannot be clamped.
Open Surgical Repair After Endovascular Treatment with Endologix Stent Graft: A Case Report
(2015) Coskun, Isa; Demirturk, Orhan Saim; Tunel, Huseyin Ali; Andic, Cagatay; Gulcan, Oner
Endovascular treatment of abdominal aortic aneurysm repair is increasingly being used today. We report a 72-year-old male patient who underwent open surgical repair due to separation of Intu Trak Powerlink XL (Endologix) endovascular stent graft four months after endovascular intervention for abdominal aortic aneurysm with 9.5 cm diameter.
Positive Clinical Outcomes of The Saphenous Vein Interposition Technique for Ruptured Popliteal Artery Aneurysm

Popliteal artery aneurysms (PAAs) can be treated successfully by surgical and endovascular methods; however, the best treatment strategy for a ruptured PAA has yet to be established. We assessed the clinical results of using saphenous vein interposition to treat ruptured PAAs in our hospital. The subjects of this study were seven men (average age 59 years, range 43-71 years), who underwent emergency surgery for a ruptured PAA at our hospital between January 2007 and November 2012. The patients were assessed after 1, 6, and 12 months, postoperatively. All included patients underwent saphenous vein graft interposition via a medial approach. No complications or graft thromboses were encountered in the immediate postoperative period. The patients were discharged after an average of 4 days postoperatively (range 3-5 days). The patients were followed up for an average of 32 months (range 2-60 months). The medium-term graft patency was 100 %. No patients suffered early or medium-term limb loss and there was no mortality. Based on our positive results, saphenous vein graft interposition should be considered as the first choice of surgical treatment for a ruptured PAA.
Predictors of in-hospital mortality following redo cardiac surgery: Single center experience
(2015) Colkesen, Yucel; Coskun, Isa; Cayli, Murat; Gulcan, Oner; 26527452
Purpose: Redo cardiac operations represent one of the main challenges in heart surgery. The purpose of the study was to analyze the predictors of in-hospital mortality in patients undergoing reoperative cardiac surgery by a single surgical team. Methods: A total of 1367 patients underwent cardiac surgical procedures and prospectively entered into a computerized database. Patients were divided into 2 groups based on the reoperative cardiac surgery (n = 109) and control group (n = 1258). Uni-and multivariate logistic regression analysis were performed to evaluate the possible predictors of hospital mortality. Results: Mean age was 56 +/- 13, and 46% were female in redo group. In-hospital mortality was 4.6 vs. 2.2%, p = 0.11. EuroSCORE (6 vs. 3; p < 0.01), cardiopulmonary bypass time (90 vs. 71 min; p < 0.01), postoperative bleeding (450 vs. 350 ml; p < 0.01), postoperative atrial fibrillation (AF) (29 vs. 16%; p < 0.01), and inotropic support (58 vs. 31%; p = 0.001) were significantly different. These variables were entered into uni- and multivariate regression analysis. Postoperative AF (OR 1.76, p = 0.007) and EuroSCORE (OR 1.42, p < 0.01) were signifi cant risk factors predicting hospital mortality. Conclusions: Reoperative cardiac surgery can be performed under similar risks as primary operations. Postoperative AF and EuroSCORE are predictors of in-hospital mortality for redo cases.

(2015) Coskun, Isa; Andic, Cagatay; Demirturk, Orhan Saim; Gulcan, Oner
Pseudoaneurysm of the superficial femoral artery after a traumatic fracture of the femur is rarely seen. In the present study, we reported treatment with endovascular embolization and surgery in a 9-year-old male patient in whom superficial femoral artery pseudoaneurysm which developed after traumatic, comminuted femoral distal diaphyseal fracture.
