    Dextrane 40 followed by cardiac arrest
    (2000) Turkoz A.; Gulcan O.; But A.K.; Hazar A.; Ersoy O.
    Anaphylactic reaction due to dextrane 40 is uncommon. A case of anaphylactic reaction followed by cardiac arrest after intravenous dextran 40 infusion in postoperative period is reported. In this case, Cardiopulmonary resuscitation was continued for 116 min after the cardiac arrest and the case was recovered completely. The possible etiology, manifestations, and management of the adverse drug reaction are discussed.

    Internal mammary artery atherosclerosis in segments removed during coronary artery bypass grafting surgery and C. Pneumoniae infection
    (2004) Ege E.; Paç M.; Durmaz R.; Bulut Y.; Hazar A.; Emmiler M.; Aydin N.E.
    Objective: Recent studies suggest the association of atherosclerotic cardiovascular disease with Chlamydia pneumoniae infection. We investigated C. pneumoniae DNA in internal mammarian artery (IMA) (used as a coronary bypass conduit) and its relationship with atherosclerosis. Methods: Sixty-six consecutive patients who underwent coronary artery bypass grafting (CABG) during an eight-month period were included in this study. From all patients, we attempted to obtain surplus segments of harvested IMA grafts. The vessels were examined histopathologically, and presence of C. pneumoniae DNA in IMA grafts was assessed by polymerase chain reaction (PCR). Results: C. pneumoniae DNA was found in 7 (10.6%) of 66 IMA specimens. The light microscopic examinations of IMA segments from the C. pneumonia positive group showed atherosclerotic intimal changes in four of the seven patients. These atherosclerotic changes were type II in three patients and type III in one patient according to the AHA classification. The rest of the IMA segments from 62 patients did not show any discernible atherosclerotic lesion. Conclusion: The IMA graft examination by PCR and histopathology may be helpful in the determination of future graft patency for IMA bypass surgery.

    Peripheral vascular injuries
    (2001) Cihan H.B.; Gülcan O.; Hazar A.; Türköz R.
    Between 1994-2000, 60 peripheral vascular injuries were admitted to the Turgut Ozal Medical Center Thoracic and Cardiovascular Surgery Clinic. Forty eight (80%) of patients were male, twelve (20%) were female and their age ranged from 5 to 70 years (mean 28.9 years). The causes of injuries were related to penetrating device in 34 (56.6%), gun shots in 14 (23.3%), blunt trauma in seven (11.6%) and iatrogenic causes in five(8.3%). Total laceration, partial laceration and pseudoaneurysm were observed in 45 (75%), 14 (23.3%) and one (1.6%) respectively. The localization of injuries were the upper limbs in 34(56.6%) and the lower limbs in 26 (43.4%). The vascular injury localizations in order of frequency were femoral artery in 12 cases (20.75%), radial artery in ten cases (17%), popliteal artery in ten cases (15%), brachial artery in nine cases (15%), axillary artery in nine cases (13.2%), ulnar artery in six cases (11.3%) and tibial artery in four cases(7.4%). There were nearby venous injuries in nine patients (15%) and neural injuries in ten patients (16.6%). The patients' mean admission time to the hospital was 3 hours and 30 minutes and mean operation time for revascularization was within 95 minutes. The operative techniques were autogenous saphenous vein graft interposition in 27 cases (45%), resection and end-to-end anastomosis in 19 cases (31.6%), lateral repair in ten cases (16.6%), synthetic graft insertion in three cases (4.8%) and ligation in one case (1.6%). Our success rate was 98.2% in salvaging the limbs. Mean length of hospital stay was 14.4 days. Mortality was not observed during the hospital stay.
