Background: Balloon angioplasty (BA) is effective in relieving neoaorta recoarctation (reCoa) after the Norwood procedure. However, recurrence is not uncommon and risk factors for success and recurrence require further elucidation. We report the results of BA for reCoa following the Norwood procedure. We examine acute results and risk factors associated with success and recurrence after BA.
Methods: Patients who underwent BA between November 2000 and June 2010 were studied. Factors for immediate success and recurrence after BA were determined using logistic regression. Recurrence-free survival was evaluated using the Kaplan-Meier curve.
Results: Forty-seven angioplasties were performed in 39 patients. Mean age at catheterization was 5.0 ± 4.1 months. BA was successful in 40 angioplasties (85.1%). A higher preprocedure gradient across the coarctation (P = 0.04) and a higher ratio of balloon to descending aorta (P = 0.01) were associated with success. Six patients required redilation. Risk factors for recurrence included older age at Norwood (P = 0.02), younger age (P = 0.03), lower weight (P = 0.04) and smaller body surface area at balloon angioplasty (BA) (P = 0.04), and shorter duration between surgery and angioplasty (P = 0.03). Freedom from recurrence from the first catheterization was 82% after 6 months and 78% after 1 year. There were no neurologic sequelae or deaths.
Conclusions: BA is effective acutely and long term with limited morbidity and mortality. Recurrence occurs usually within the first year. Delay in performing the initial angioplasty may be beneficial in reducing the risk of recurrence, but further study is needed.

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.

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.

Background: Multisystem inflammatory syndrome in neonates (MIS-N) is a rare condition thought to be associated with prenatal exposure to maternal severe acute respiratory syndrome coronavirus 2 infection. This immune-mediated hyperinflammation has been described in neonates with multiorgan dysfunction, including cardiopulmonary, encephalopathy, coagulopathy, and vascular complications. However, renovascular complications in MIS-N are rare.
