The results of percutaneous transluminal angioplasty of renal arteries (PTA) were evaluated in 43 patients followed up for 2-39 months (mean: 14 months). The benefit of PTA was higher (82%) in hypertensives with arterial fibrodysplasia (n = 11) than in atherosclerotic vascular lesions (53%, n = 19). Of 15 patients with reduced renal function before PTA, the glomerular filtration rate rose in seven. A major complication was in one patient arterial dissection and in another one loss of function of the transplanted kidney due to acute tubular necrosis. The results confirm that PTA is an important contribution to the treatment of renovascular hypertension.

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.

Stenosis within the arteriovenous fistula (AVF) of hemodialysis patients leads to vascular access dysfunction and inadequate hemodialysis. Percutaneous transluminal angioplasty (PTA) is the standard therapy for stenosis. However, rates of restenosis and loss of access patency remain high.

Background: Undiagnosed and untreated atherosclerotic renal artery stenosis (ARAS) can result in end-stage kidney disease (ESKD). To obtain an accurate diagnosis, it is crucial to recognize the symptoms and signs suggesting renal artery stenosis (RAS) and perform appropriate diagnostic and treatment procedures afterward.
Case Presentation: We present a case of a 60-year-old female patient with hypertensive crisis, acute heart failure (HF), and pulmonary edema as the initial signs of acute kidney injury (AKI) caused by right RAS and left renal artery occlusion in the presence of severe aortic atherosclerosis revealed on computed tomography angiography (CTA) of the abdomen.

Objective: In this study, we aimed to retrospectively review patients with post-thrombotic syndrome (PTS) and investigate its long-term outcomes, and a novel classification were presented across multiple institutions.
Methods: We retrospectively evaluated patients with PTS who underwent endovascular therapy at two institutions between January 2018 and September 2023. Baseline patient demographics, lesion characteristics, and in-hospital and follow-up outcomes were collected and analyzed retrospectively.
