Introduction: Creating functional arteriovenous fistulae (AVF) at the wrist is challenging in paediatric patients because of the small calibre of the blood vessels.
Methods: We report our experience with AVF surgery in children younger than 15 years of age using microsurgical techniques. Twenty-five patients underwent AVF surgery between 2003 and 2015 (20 for haemodialysis, 4 for plasmapheresis and 1 for parenteral nutrition). Median (range) age was 9 (2-15) years and median weight was 24 (8-61) kg.
Results: The one-month occlusion rate was 8%. The primary and secondary patency rates at 1, 2, 3 years were: 60%, 49%, 42%, and 82%, 72%, 54%, respectively. The median (range) maturation time was 4.53 (0.5-11.2) months. We found no statistically significant effect of patient age, body weight, type of AVF and indication for AVF creation on the primary and secondary patency rates.
Conclusions: Microsurgical AVF creation at the wrist can be performed with satisfactory results and should be the preferred technique in the paediatric population.

Background: Arteriovenous fistulas (AVFs) in kidney transplant recipients are sometimes closed, either as a policy or due to complications. We collected data on the incidence of complications after AVF closure in a national cohort of transplanted patients.
Methods: Patients who received a kidney transplant between 2000 and 2015 and had a functional AVF that was later ligated or extirpated were included.

Lower extremity arteriovenous (AV) access serves as a crucial alternative for hemodialysis when upper extremity options are no longer viable. While there are numerous reports on functional patency, limited information exists regarding complications related to venous insufficiency and postoperative quality of life. This study aims to assess the actual incidence of such complications and provide evidence-based insights for clinical decision-making.

Objective: To describe the treatment outcomes of patients who underwent Percutaneous Transluminal Angioplasty (PTA) for Central Vein Occlusive Disease (CVOD) in end-stage kidney disease and determine the association between patient profile and treatment outcomes.
Methods: A single-institution, retrospective review of patients aged 18 and above with end-stage kidney disease who underwent PTA for CVOD in the University of the Philippines - Philippine General Hospital (UP-PGH) from January 1, 2013, to December 31, 2022, was performed. These patients' demographic and clinical profiles were evaluated using means, frequencies, and percentages.
