Balloon angioplasty was performed in 200 patients with recoarctation of the aorta in a multicenter prospective study. The average age at the time of the procedure was 7.0 years (range 1 month to 26 years). Systolic pressure (mean +/- standard deviation) in the ascending aorta decreased from 134.5 +/- 23.4 to 127.4 +/- 22.0 mm Hg. The descending aortic systolic pressure rose from 92.7 +/- 18.2 to 114.1 +/- 21.6 mm Hg. Peak systolic pressure differences decreased from 41.9 +/- 19.6 to 13.3 +/- 12.1 mm Hg. The diameter of the recurrent coarctation site increased from 5.2 +/- 2.9 to 8.9 +/- 3.4 mm. After angioplasty residual pressure differences of less than or equal to 20 mm Hg were found in 79.4% of the patients. Five patients died of complications related to the procedure (2.5%). Two deaths were directly related to the technical aspects of the procedure and 3 patients died because of the severity of the underlying disease. One additional patient had a cerebrovascular accident. Femoral artery complications occurred in 17 patients (8.5%) and 8 patients required surgical thrombectomy. Balloon angioplasty offers a satisfactory alternative to surgery for recurrent coarctation; both results and complications compare favorably with surgical therapy.

Balloon-mounted versus self-expandable stent in failed neurothrombectomy: a post hoc analysis of the SAINT study.
J Neurointerv Surg

Department of Neurology, Emory University School of Medicine, Atlanta, Georgia, USA
Background: Previous studies have shown that when thrombectomy has failed, rescue intracranial stenting is associated with better clinical outcomes compared with failed reperfusion. However, comparative data regarding stent type are lacking.
Objective: To compare the procedural and clinical outcomes of balloon-mounted stents (BMS) with those of self-expandable stents (SES).
Carotid disease treatment modality and its association with post-operative vasoactive medication utilization and hospital length of stay.

Objective: Carotid artery disease is a major cause of stroke for which the standard treatment has traditionally been a combination of medical management and intervention, including both carotid endarterectomy (CEA) and transfemoral carotid artery stenting (TF-CAS). In recent years, transcarotid artery revascularization (TCAR) has been adopted as a promising treatment following FDA approval in 2015. In terms of stroke reduction, TCAR has been found to have equivalent outcomes with CEA with shorter operative times.

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.

Optimizing the longevity of vascular access in hemodialysis patients remains a critical aspect of patient care, given the significant role of arteriovenous fistulas (AVFs) and arteriovenous grafts (AVGs) in enabling effective dialysis. Vascular access complications, such as stenosis, thrombosis, and cannulation-related damage, continue to challenge both the functionality and the sustainability of these access points. Recent advancements underscore the importance of a robust follow-up strategy, integrating clinical evaluations with diagnostic tools like color Doppler ultrasound (CDU) and emerging interventional approaches such as drug-coated balloon (DCB) angioplasty.

Department of Vascular Surgery, Beijing Tongren Hospital, Capital Medical University, Beijing, China -
Background: This study aimed to investigate the clinical outcomes of percutaneous transluminal angioplasty (PTA) in patients undergoing hemodialysis with different types of superior vena cava obstruction (SVCO) lesions.
Methods: This retrospective observational study recruited patients undergoing hemodialysis with SVCO and analyzed the clinical characteristics of SVCO. Patency rates were collected for patients treated with PTA and were assessed using the t-test, U-test, log-rank test and survival analyses such as the Kaplan-Meier method.
