    Surgical Interventions for Late Complications of Arteriovenous Fistulas
    (2014) Belli, Sedat; Yabanoglu, Hakan; Aydogan, Cem; Parlakgumus, Alper; Yildirim, Sedat; Haberal, Mehmet; 25058786
    Our aim was to determine the most effective surgical treatment for arteriovenous fistula (AVF) complications after all other methods of salvage have failed. We evaluated 110 patients for 139 complications that occurred after the initial AVF placement and for whom surgical intervention was the last hope for retaining fistula access. Vascular steal syndrome and venous hypertension were the most common complications seen in our patients. The anastomoses of 17 of the vascular steal syndrome cases were narrowed either by stitches or by a polytetrafluoroethylene graft. The second most performed revision surgery was excision of the aneurysm and repair with primary suturing, followed by excision of the aneurysm and interposition grafting. Successful surgical outcomes were achieved in 111 of 139 procedures after revision surgery without constructing a new AVF. AVF salvage surgery is of paramount importance in order to increase the patency rate, which prolongs survival and increases the patient's quality of life.

    Evaluation of Demographic and Clinical Characteristics of Patients who Attempted Suicide by Self-Inflicted Burn Using Catalyzer
    (2015) Yabanoglu, Hakan; Aytac, Huseyin Ozgur; Turk, Emin; Karagulle, Erdal; Belli, Sedat; Sakallioglu, Ayse Ebru; Tarim, Mehmet Akin; Moray, Gokhan; Haberal, Mehmet; 25692434
    Our aim was to assess demographic and clinical characteristics of patients treated at our units who attempted suicide by self-incineration, and to compare the results of burns with or without catalyzer use. Twenty patients who attempted suicide by self-incineration were examined in terms of clinical and demographic characteristics. Average age of the study population was 35 years (range 13-85 years). Average percentage of total body surface area burn was 53% (9%-100%). Six (30%) patients used gasoline and 5 (25%) used paint thinner in order to catalyze burning. Of these 11 patients who used a catalyzer, 5 (45.4%) had inhalation injury and 7 (63.6%) died. Among 9 patients who did not use any catalyzer, 1 (11.1%) had inhalation injury and 4 (44.4%) died. In general, inhalation injury was diagnosed in 6 patients (30%) while 11 (55%) patients died. A high morbidity and mortality rate was found in patients who used a catalyzer.

    Results of Surgery in General Surgical Patients Receiving Warfarin: Retrospective Analysis of 61 Patients
    (2015) Belli, Sedat; Aytac, Huseyin Ozgur; Yabanoglu, Hakan; Karagulle, Erdal; Parlakgumus, Alper; Nursal, Tarik Zafer; Yildirim, Sedat; 25692422
    The aim of this study is to investigate postoperative complications, mortality rates, and to determine the factors affecting mortality on the patients receiving warfarin therapy preoperatively, as well as comparing the results obtained from emergency and elective surgeries. Surgical outcomes of 61 patients on long-term oral anticoagulation with warfarin who underwent surgery in our center were retrospectively reviewed over an 8-year period. Thirty-three (54.1%) patients were female, with a mean age of 53 years. Mitral valve replacement (62.3%) was the most frequent indication for chronic anticoagulation therapy. Twelve out of 61 (19.2%) patients underwent emergency surgery; 59 (96.7%) operations were classified as major surgery. We did not observe any thromboembolic events on patients receiving our bridging therapy protocol. Cardiopulmonary dysfunction (CPD; 19.7%) and hemorrhage (16.4%) were the most encountered postoperative complications. Presence of CPD, bleeding, endocarditis, and mortality were statistically significant for emergency surgeries when compared with the results obtained from elective surgeries. There were 5 (8.2%) deaths observed during follow-up. It was found that advanced age, prolonged duration of operations, and presence of CPD had a statistically significant effect on mortality (P < 0.05). The patients receiving oral anticoagulant had high postoperative complication and mortality rates. This case was more evident in emergency surgeries. It is recommendable that as mortality is more apparent in the patients who undergo emergency surgeries-being older, having long duration of operations as well as CPD. Therefore during the postoperative follow-up process, the patients should be closely monitored.
