Anchor Versus Parachute Suturing Technique in Arteriovenous Fistula Creation for Hemodialysis

Arterio-venous Fistula Clinical Trial

Official title: Anchor Versus Parachute Suturing Technique in Arteriovenous Fistula Creation for Hemodialysis

Status Recruiting

Clinical Trial Summary

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.

Clinical Trial Description

Introduction End-stage kidney disease (ESKD) is increasing worldwide and is likely to increase further because of aging populations and the increased prevalence of type II diabetes mellitus. It is a chronic and irreversible condition associated with substantial morbidity and high mortality and constitutes a heavy financial burden on healthcare systems. The reduced hemodialysis-related mortality rate has increased the need for dependable vascular access. For end-stage renal failure patients, arteriovenous fistulas (AVFs) are the reliable hemodialysis access option. Compared to tunneled central venous catheters, they had a reduced risk of systemic sepsis and a lower overall cardiovascular death rate. Numerous factors for early failure and "arrested maturation" have been implicated, including abnormal anastomotic hemodynamics, the diameter of the vein, hyperplasia of intima and stenosis or scarring, insufficient arterial flow, and suture technique. The surgical technique is an essential aspect in determining AVF surgery success. The lack of data supporting any anastomotic suture technique is better in AV access patency, or less complication makes the choice of suture technique for AV access formation dependent on the operator's discretion and their best clinical judgment. For this reason, we conducted prospective research on AVFs created using two distinct continuous suturing techniques, the anchor technique, and the parachute technique, to examine the impact of these two techniques on the initial outcomes of AVFs. 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). ;
