Study of Arteriovenous Fistula Cases in a Tertiary Care Hospital: A Cross-sectional Study from Marathwada region of Maharashtra State

Abstract

Introduction: Arteriovenous fistulas are a preferred choice for hemodialysis access in chronic kidney disease patients. There is increased adoption of arteriovenous fistula creation in Marathwada region of Maharashtra state. Our objective is to study various arteriovenous fistulas that have been created in our center.

Methods: This is a descriptive cross-sectional study conducted in a tertiary care hospital including all cases of arteriovenous fistula creation from March 2024 to February 2025. Convenient sampling method was used. Detailed vascular mapping and color Doppler ultrasonography was done in the bilateral upper limb as preoperative preparation and to choose a site for arteriovenous fistula creation. Data were entered into the Statistical Package for the Social Sciences version 20 for analysis.

Results: Among 100 patients, the most common location was brachiocephalic 40 (40%) patients followed by brachiobasilic 36 (36%), radiocephalic 22 (22%), and arteriovenous graft between the brachial artery and axillary vein 2 (2%). The mean duration of hospital stay was 1.44 days. Six (6%) patients required re-intervention, all within 24 hours. Four (4%) patients had a failure of arteriovenous fistula requiring the creation of a new arteriovenous fistula.

Conclusions: Brachiocephalic was the most common location for arteriovenous fistula creation. Reintervention was not common.
