Introduction: Even though it has been reported that femoropopliteal artery endovascular revascularization is often performed with antegrade femoral artery interventions, which are technically relatively challenging, having the advantage of better control, it has also been reported that recanalization failure may occur in approximately 20% of patients and some materials have been developed for this reason. Aim: To evaluate the safety of retrograde popliteal artery intervention and our procedural success rate for symptomatic femoropopliteal artery occlusive disease. Material and methods: A total of 95 endovascular revascularization procedures were performed for treating symptomatic occlusive peripheral artery disease in the study period. Inclusion criteria were defined as patients who underwent endovascular revascularization procedures for symptomatic femoropopliteal artery occlusive disease. Patients who underwent a percutaneous endovascular procedure for iliac artery or below-knee arterial occlusive disease in the same session and patients who had previously undergone peripheral arterial bypass grafting or endovascular treatment for existing femoropopliteal artery disease were excluded. Results: We evaluated 45 peripheral endovascular procedures performed on 39 patients with a mean age of 62.49 ±11.38 years in our hospital for chronic femoropopliteal artery occlusive disease. Twelve (26.7%) of the endovascular treatment procedures were performed with retrograde access through the popliteal artery (Group 2). In neither group were any complications of arterial rupture, distal embolism, early thrombosis, or pseudoaneurysms observed. Conclusions: We are of the opinion that the retrograde popliteal artery technique is an effective and safe intervention option in endovascular revascularization, particularly in the revascularization of the long segment and complex femoropopliteal artery occlusions.

Objectives: Since nonvalvular atrial fibrillation is persistent in nature, patients with chronic nonvalvular atrial fibrillation are at life-time risk for development of thromboembolic events. Several novel oral anticoagulants have entered the market and there has been a growing body of evidence regarding their efficacy in prevention of ischemic stroke and arterial thromboembolism. The present study sought to compare the baseline characteristics between patients presenting with upper and lower extremity arterial thromboembolism developed secondary to nonvalvular atrial fibrillation.Methods: This retrospective study was made up of patients presenting with acute upper or lower extremity arterial thromboembolism as the first presentation of atrial fibrillation. Patients were included if they had acute upper or lower critical limb ischemia symptoms lasting for less than one week. Patients in whom chronic peripheral artery disease was diagnosed were also excluded to prevent potential confounding.Results: Overall, 46.9% of patients presented with upper extremity arterial thromboembolism and 53.1% of patients presented with lower extremity arterial thromboembolism. None of the baseline characteristics showed significant difference between patients with upper and lower extremity arterial thrombosis.Conclusion: It was observed that there was no significant difference in the incidence of extremity involvement of acute arterial thromboembolism occurring in patients with nonvalvular atrial fibrillation in our study, and we think that acute arterial thromboembolism must be taken into consideration as one of the first signs and symptoms of atrial fibrillation.

Superficial venous aneurysms, which are mostly asymptomatic and detected when patients were referred to for the treatment or evaluation of a femoral or inguinal hernia or soft tissue masses, are associated with a risk of developing pulmonary embolism. We aimed to present a case of a greater saphenous vein aneurysm of which its misdiagnosis possesses morbidity risk and confused with inguinal hernia. A 45-year-old female patient admitted to our clinic with swelling and pain in her right groin that had been present for about three years. The patient was also treated with inguinal hernia repair once due to her related complaints. A venous color doppler ultrasound was performed for differential diagnosis and a 70x31-mm sized fusiform proximal greater saphenous vein aneurysm and a grade-4 pathologic reflux in the right saphe-nofemoral junction was observed in the ultrasonographic examination. As a result, the swelling detected in the inguinal region should be evaluated in terms of possible superficial venous aneurysm, which may cause thromboembolism and ruptures, and this condition, which is frequently confused with inguinal hernia, should be taken into consideration and taken under operation as soon as possible in case of its presence.

The article discusses the significance of lateral chest radiography to detect the retained surgical sponge. At postoperative period, the plain radiography of the chest showed hypodense mass with the thick peripheral rim, characteristic whirl-like pattern, suggestive of foreign body on the right heart border. The radiographic detection of the sponges on standard antero-posterior projections is difficult due to the exposure factors, other confusing linear markers and metallic densities.

Purpose: The hypoxia inducible factor (HIF)-1 is a dimeric protein complex that plays an integral role in the body's response to hypoxia. This study aimed to analyze the regulation of HIF-1α following vascular and/or endovascular surgery in peripheral arterial disease (PAD) patients., Materials and Methods: A total of 40 patients with PAD (≥Rutherford category 3) were included in this prospective study. The mean age was 61.9±9.2 years. Open surgery was performed in 16 patients, and endovascular intervention was performed in 34 patients. At preoperative (T1), postoperative day 1 (T2), and month 3 (T3), the serum HIF-1α levels were checked using the ELISA technique., Results: At T3, the ankle-brachial index was significantly higher than the preoperative value (P<0.001). Serum HIF-1α levels at T1, T2, and T3 were 2.0±1.7 ng/mL, 1.9±1.7 ng/mL, and 1.6±1.4 ng/mL, respectively. Serum HIF-1α levels between T1 and T3 and between T2 and T3 were significantly different (P<0.05). The preoperative HIF-1α levels were lowest in iliac lesions compared to femoropopliteal or tibial lesions., Conclusion: The HIF-1α levels were decreased in all patients on postoperative days, T2 and T3, compared with the preoperative values. Our results indicated that HIF-1α may be a surrogate marker after revascularization in patients with PAD. Further studies are needed to analyze the sensitivity, specificity, and cut-off values of HIF-1α in patients with PAD.
