Introduction: Balloon angioplasty maturation (BAM) is a salvage method for autologous arteriovenous fistula (AVF) maturation failure. AVF creation using small-diameter veins is considered to have poor outcomes. Therefore, this study aimed to explore the long-term patency of small-diameter veins (≤3 mm) using BAM.
Methods: BAM was performed if the fistula failed to mature and function adequately to provide prescribed dialysis.
Findings: Out of 61 AVFs, 22 AVFs successfully matured without further intervention (AVF group) and 39 AVFs failed to mature. Except for 1 patient who required peritoneal dialysis, the remaining 38 patients received salvage BAM, and 36 of those successful matured (BAM group). Kaplan-Meier analysis revealed no significant differences between the AVF and BAM groups in terms of primary functional patency (p = 0.503) and assisted functional patency (p = 0.499). Compared with the AVF group, the BAM group had similar assisted primary functional patency (1-year: 94.7% vs. 93.1%; 3-year: 88.0% vs. 93.1%; 5-year: 79.2% vs. 88.3%). In addition, there were no significant difference between groups in the duration of primary functional patency and assisted primary functional patency (p > 0.05). Multivariate analyses showed that vein diameter and number of BAM procedures were independent predictors of primary functional patency in the AVF group and BAM group, respectively. Patient with 1 mm increase in vein size had 0.13-fold probability of having decreased duration of patency (HR = 0.13, 95% CI: 0.02-0.99, p = 0.049), while patients who received two times of BAM procedures were 2.885 as likely to have decreased duration of primary functional patency (HR = 2.885, 95% CI: 1.09-7.63, p = 0.033) than patients who received one BAM procedure.
Discussion: BAM is a relatively effective salvage management option with an acceptable long-term patency rate, even for small cephalic veins.

Background And Objective: Septoplasty and turbinate reduction surgery (STR) is hypothesized to affect pulmonary function by modifying airway dynamics. This study investigates the impact of STR-mediated improvements in nasal patency on pulmonary function tests (PFTs).
Methods: In a prospective analysis, 37 adult patients undergoing STR were enrolled.

Objective: To evaluate the safety and efficacy of chocolate balloons in patients with chronic limb-threatening ischemia (CLTI) and infrapopliteal artery disease, and compare them with conventional balloons.
Methods: This single-center retrospective study included 167 patients with CLTI and infrapopliteal who underwent endovascular intervention with or without chocolate balloons from September 1, 2019 to June 30, 2023. The primary endpoint was amputation-free survival (AFS).
Introduction: Auto-expandable ureteral stents can be an alternative to percutaneous nephrostomy (PCN) in refractory ureteral stenosis. Our aim is to analyse results and complications of ureteral stents in our centre.
Methods: Retrospective review of OptiMed® expandable ureteral stents placed in our centre (1996-2022).

Autogenous arteriovenous fistula (AVF) is the vascular access of choice for chronic kidney disease to patients requiring hemodialysis. However, there still needs to be more consensus on whether the best surgical approach is an end-of-vein to side-of-artery (ETS) or a side-of-vein to side-of-artery (STS) anastomosis. This study aims to compare venous maturation rates, mid-term patency and post-operative steal syndrome rates between ETS and STS techniques for arteriovenous fistulas.
