Anchor Versus Parachute Suturing Technique in Arteriovenous Fistula Creation for Hemodialysis

Overview

Randomized controlled study to compare the results of two surgical techniques for AVF creation, including the anchor technique (Group A) and parachute technique (Group B). The study population will be patients referred to the Vascular surgery department for the creation of Hemodialysis access. Patients will be advised to undergo elective surgery for AVF once their renal Glomerular Filtration Rate Estimated (eGFR) is less than 15 ml/min. primary outcome: Functional Maturation of Arterio-venous Fistula \[ Time Frame: Six Months\] Ready fistula for cannulation, vein length at least 10 cm, diameter more than 6 mm, depth not more than 6 mm, and ability of the access to deliver a flow rate of 600ml/min and maintain dialysis for 4 hours.

Introduction Aim of the work To compare the results of two surgical techniques for AVF creation, including the anchor technique (Group A) and parachute technique (Group B). Patients and the method Study location: We will submit the study protocol for approval by Kafr ElSheikh medical research ethics committee, faculty of medicine, Kafr ElSheikh University. Study design: Randomized controlled study will be conducted in the department of vascular surgery in Kafr El Sheikh. Time of study: We started in march 2022. Study population: The study population will be patients referred to the Vascular surgery department for the creation of Hemodialysis access. Patients will be advised to undergo elective surgery for AVF once their renal Glomerular Filtration Rate Estimated (eGFR) is less than 15 ml/min. The number of patients: This study will be done on 150 cases, 75 cases in group A (anchor technique) and another 75 in group B (parachute technique).
