Purpose: The purpose of this study was to assess the effectiveness of anastomotic pseudoaneurysms (APAs) endovascular treatment following aorto-iliac-femoral surgical reconstruction.
Basic Procedures: We retrospectively evaluated 54 patients who underwent aorto-iliac-femoral bypass (72 APAs). Follow-up was performed with echo-color-Doppler and/or computed tomography angiography at 1, 3, and 6 months after the procedure and then yearly. We compared clinical success in terms of mortality between aortic APAs and nonaortic APAs (iliac-femoral-popliteal).
Main Findings: Immediate technical success was 100%. No periprocedural complications occurred. Six patients died during follow-up due to causes not related to APA and 5 due to sepsis at 3 months after the procedure. Thirty-day mortality was 9% overall, and we did not register any statistically significant different between aortic APA and nonaortic APA groups. During a mean follow-up of 25.5 months (range: 3-72), we registered 3 occlusions of stent-graft leg, respectively, at 3 days, 7 days, and 24 months after the procedure, 2 type I endoleaks and 1 type III endoleak. Primary clinical success rate was 87.2%, and secondary clinical success was 95.7%.
Conclusions: Endovascular treatment resulted as a valid alternative to open surgery and could be proposed as the treatment of choice for APAs especially in patients with a high surgical risk.

Background: Due to the heterogeneity of literature findings, stent type selection for the endovascular treatment of complex aorto-iliac occlusive disease remains challenging. The BELSTREAM study, a physician-initiated, prospective, multicenter, single-arm study, aims to report the safety and efficacy of the balloon expandable LifeStream Peripheral Stent Graft System (BD, Tempe, Arizona, USA) for the treatment of complex TASC C and D aorto-iliac artery lesions.
Methods: Seventy patients and 133 lesions were included at six Belgian institutions.

The underlying mechanisms of abdominal aortic aneurysms (AAAs) are not fully understood. Given the multifactorial nature of AAA development and progression, a comprehensive approach is essential. Throughout my academic career, I conducted various studies on AAA.

Chronic limb-threatening ischemia (CLTI) occurs in the advanced stage of peripheral artery disease and is associated with high risks of mortality and amputation. Universal management strategies are not always applicable, owing to population diversity, and the Western trials may not be applicable to Japanese patients, owing to differences in demographics and clinical profiles. This paper examines the outcomes of revascularization in Japanese CLTI patients and emphasizes the benefits of tailored management.

Objective: Antithrombotic therapy improves endovascular intervention outcomes for peripheral artery disease. However, there are limited data guiding the choice and duration of these adjuvant therapies. Thus, we explored current antithrombotic prescribing preferences among vascular interventionalists, hypothesizing that there are varied and inconsistent treatment practices among providers.

Renal ischaemia due to renal artery stenosis produces two differing responses - a juxtaglomerular hypertensive response and cortical renal dysfunction. The reversibility of renal impairment is not predictable, and thus renal revascularisation is controversial. This study aims to test the hypothesis that the hypertensive response to renal ischaemia reflects viable renal parenchyma, and thus could be used to predict the recovery in renal function.
