Endovascular treatment of isolated iliac artery aneurysms with anaconda stent graft limb.

Isolated aneurysms of the iliac arteries are relatively rare conditions that traditionally have been treated by surgical reconstruction. We report our experience with endovascular treatment of iliac artery aneurysms (IAAs) with Anaconda stent graft limb. Two male patients were found to have 4.5 and 3.6 cm isolated common IAAs, respectively. The endograft was successfully advanced and deployed precisely to the intended position in both cases. In one case the internal iliac artery was embolized. No type I or II endoleak was observed immediately after the procedure. In one patient postimplantation fever (>38°C) and gluteal claudication occurred. After 2 years followup both iliac endovascular stent grafts are patent and without endoleak. Endovascular treatment with Anaconda limb stent graft seems to be a safe and feasible alternative to open surgery.

Factors associated with the development of superficial vein thrombosis in patients with varicose veins.

INTRODUCTION: Superficial vein thrombosis (SVT) is a common and controversial clinical entity. Recent studies have demonstrated that SVT should be seen as a venous thromboembolism (VTE). The objective of this study was to investigate the prevalence of thrombophilia defects and to estimate the role of age, sex and body mass index (BMI) in patients with varicose veins (VVs) and SVT. MATERIALS AND METHODS: A total of 230 patients with VVs, 128 with, and 102 without SVT underwent thrombophilia testing included factor V Leiden, prothrombin G20210A, methylenetetrahydrofolate reductase and plasminogen activator inhibitor- 1 mutations, protein C, protein S (PS), anti-thrombin III and plasminogen deficiencies and levels of A2 antiplasmin, activate protein C resistance and lupus anticoagulant. According to Clinical-Etiology-Anatomy-Pathophysiology (CEAP) classification patients were categorized in two subgroups: moderate disease (C2,3) and severe disease (C4,5,6). Age and body mass index were also assessed. RESULTS: The prevalence of thrombophilia defects was significantly higher in patients with moderate disease and SVT (p=0.002). In the C2,3 group, SVT was associated with PS deficiency (p=0.018), obesity (p<0.001), male gender (p=0.047) and age (p<0.001). There were no significant differences in patients with severe disease. CONCLUSIONS: Age, male sex, obesity and PS deficiency are factors associated with SVT development among patients with VVs having moderate disease (C2,3).
