Abstract The 1691 (G>A) factor V Leiden (FVL) and 20210 (G>A) prothrombin (PT) mutations are the two most common genetic risk factors in venous thromboembolism. The 677 (C>T) methylene tetrahydrofolate reductase (MTHFR) mutation is the most frequently mentioned as an independent genetic risk factor for venous thromboembolism. As there are limited published data on the prevalence of the 1691, 20210 and 677 mutations in our population, the aim of this study was to determine the frequencies and association of these deep vein thrombosis mutations in the Bosnian population. This study included 111 thromboembolic patients and 207 healthy subjects with absence of known risk factors for venous thromboembolism. Genotyping of the 1691, 20210 and 677 mutations was done by polymerase chain reaction (PCR), followed by restriction digestion with MnlI, HindIII and HinfI enzymes. Out of the 111 patients, 18.0% were heterozygous and 2.70% were homozygous for the 1691 mutation. Among 207 healthy controls, 3.86%, were heterozygous for the 1691 mutation. This study confirmed the association of the 1691 mutation with deep vein thrombosis in the Bosnian population odds ratio (OR) [95% confidence interval (CI)] = 6.0 (2.62-14.14); p = 0.0001). The 20210 mutation was detected in 2.70% of patients and it was totally absent in the control group. Allele and genotype frequency of 677 did not differ significantly between the cases and controls (χ2 = 1.03; p = 0.309).

Surgical revascularization of the heart (CABG - coronary artery bypass grafting) is one way of treating coronary heart disease. Bleeding is one of the serious and frequent complications of heart surgery and can result in increased mortality and morbidity. Hemostasis disorder may be secondary consequences of surgical bleeding, preoperative anticoagulant therapy, and the use of cardiopulmonary bypass. Tests used for routine evaluation of the coagulation system are activated partial thromboplastin time (APTT) and international normalized ratio (INR). The study encountered 60 patients who were hospitalized at the Clinic for Cardiovascular Diseases, University Clinical Center Tuzla. Patients underwent elective coronary artery bypass heart surgery either with cardiopulmonary bypass (on-pump CABG) or without it (off-pump CABG). The aim of this study was to compare the changes in coagulation tests (APTT, INR) in patients who were operated on-pump and patients operated off-pump. Our study showed that the values of APTT and INR tend to increase immediately after surgery. Twenty-four hours after surgery these values are declining and they are approaching the preoperative values in all observed patients (p <0.05). Comparing APTT between the groups we found that postoperative APTT levels are significantly higher in the group of patients who underwent surgery with cardiopulmonary bypass (p <0.05). Changes in coagulation tests after surgical revascularization of the heart are more pronounced in patients who were operated with on-pump technique compared to patients operated off-pump technique.

INTRODUCTION Techniques of coronary artery revascularisation on the beating heart have evolved with an attempt to reduce the potential deleterious effects of extracorporeal circulation. It is of particular value in those with a calcified or atheromatous ascending aorta. Total arterial revascularisation is ideal. CASE REPORT We describe a case of 66 year-old male patient, previously suffered mild cerebrovascular incident, schedueled for myocardial revascularisation of double coronary disease with Left main stenosis. METHOD Sternotomy was done in standard fashion. Both mamary artery were harvested and distal anastomoses were made in standard fashion by Prolen 8/0. For local stabilisation Medtronic Octopus vaccum stabiliser was used. DISCUSSION Feasibility to perform arterial revascularistion by using off-pump aorta no-thouch techniqe (anaortic technique) on the patient previously suffered stroke and with increasd risk of the same complication was presented. This technique is recommended whenever technically feasible.

We present a case of 71 year old man operated in our clinic for ruptured abdominal aneurysm complicated with aorto-caval fistula, which was revealed during the surgery and successfully repaired by direct sutures within the aorta. This is the first record of the aorto-caval fistula that was so far noticed in our clinic. Urgent surgery and repair of the defect conneting aorta and vena cava by direct sutures within the aorta followed by ruptured aneurysm repair with tube graft is only way of treatment. Despite its infrequent occurrence, aorto-caval fistula should always be considered in any case of ruptured abdominal aneurysm.

Study comparing the results of coronary artery bypass grafting (CABG) with and without cardiopulmonary bypass (CPB) in the treatment of left main stenosis (LMS) has not yet been made in Bosnia and Herzegovina. The main aim of this study was to compare result of CABG performed on 176 patients, in Cardiovacular clinic of University Clinical Center in Tuzla from May 1999 to January 2005, by these two methods in LMS group of patients in the early and late postoperative period. The study was divided in two parts. In the first part, early postoperative period (30 days after the surgery) has been analysed, which encompasses results of CABG in 92 patients revascularisied without CPB (OPCAB) method (Group A), and 84 patients with LMS revascularisied with CPB method (ONCAB, CCAB) (Group B). In the second part, late postoperative period (one year after surgery) has been analysed. Patients from both groups were contacted and interviewed. Total number (276 versus 278), same as average number of grafts per patients (3.0 +/- 1.45 versus 3.31 +/- 0.86 p = 0.096), was insignificantly higher in group B. Perioperative and postoperative results revealed significant differences between two groups in reduced mechanical ventilation time (2.9 versus 7.3 hours, p = 0.039), less blood transfusion requirement (200.3 versus 419.9 ml, p = 0.035) and postoperative length of stay (7.4 versus 8.3 days). Inotrop support requirement was significantly higher in group B during the surgery (14.1% versus 29.8%, p = 0.019) and postoperative period longer than 12 hours (7.6 versus 22.6%; p = 0.009). Significant difference for mortality was noticed in early postoperative period in group A (0.0 versus 5.95%, p = 0.023). There was no significant difference for any of additional procedures (7.9 versus 7.8, p = 0.802), for major complications (8.0 versus 9.1%; p = 0.985) or for mortality (7.9 versus 5.2%; p = 0.692). Patients' survival after CABG for period of 12, 24, 36 and 48 months after surgery was not statistically significant (97.0 versus 96.1%, p = 0.802; 95.5 versus 96.1%, p = 0.857; 93.2 versus 94.8%, p = 0.913; 92.0 versus 94.8%, p = 0.692). This study revealed that OPCAB is effective and safe method for treatment of LMS, and there are certain advantages in comparison to classical method in short-term follow up, with no difference in long-term results.

Although superficial thrombophlebitis is a common disorder until recently it was considered as benign disorder. Also it is associated with varicose vein at legs and it was treated effectively with conservative methods, walking and non-steroid anti-inflammatory drugs. Aims of our investigation were: determine frequency of clinically silent deep vein thrombosis at legs in patient with and without superficial thrombophlebitis, determine correlation between superficial thrombophlebitis and deep vein thrombosis regardless of localization of superficial thrombophlebitis in superficial veins of legs and determine adequacy and safety vein phlebography in early diagnosis clinically silent deep vein thrombosis in patients with superficial thrombophlebitis. Using flebography in prospective study was evaluated incidence of clinically silent deep vein thrombosis in 92 patients with varicose veins at legs. By phlebograpy in patients with varicose veins at legs and superficial thrombophlebitis at legs and without clinical signs of DVT at legs of the 49 patients we detected DVT in 12 patients (24, 48%), in three male and nine female. We detected localization of DVT in ilijacofemoral junction in 4,08% patients, although localization of DVT in femoropopliteal region was observed in 6, 12% patients and localization in crural region was in 14.28% patients. Localization of DVT at legs was detected in iliac vein in 16.66% patients, in femoral vein in 25% patients, popliteal vein 8.33% patients, anterior tibial vein 16.66%, posterior tibial vein in 25% and crural veins 8.33% patients. Also we deduced significant difference between two group of patients (chi2 = 10, 76). Such result proves thesis that in most patients with superficial thrombophlebitis and varicose veins is possibility of developing of DVT.

Our patient with peritonitis, chronical ileus and ileostoma has had the atherosclerotic occlusive changes in aorto-iliac area on both sides. Hypotensive crises must have made hemodynamic conditions worse, permitting thrombosis in the collateral circulation to cause acute ischemia of the right leg. Because of the bad general condition and infection on the anterior abdomen wall, the axillo-femoral bypass has been the only way for the arterial reconstruction and salvation of the leg.
