Using ultrasound in preoperative mapping and surveillance of arteriovenous grafts for haemodialysis improves patency rates: Single-centre experience.

Background: This study aimed to evaluate patency outcomes of arteriovenous grafts (AVGs) before and after using Duplex doppler ultrasonography (DUS) in preoperative mapping and surveillance of AVG.

Methods: In this single-centre, retrospective cohort study 212 patients receiving AVGs from January 2009 to December 2022 were included. In group 1, the creation of AVG as well as screening was based on physical examination alone.

Arteriovenous Grafts' Types of Indications and Their Infection Rate.

Background: Arteriovenous graft infection is a well-known and frequent complication. The objective of this study was to compare infection rates of primary and secondary indicated arteriovenous grafts (AVGs).

Subjects And Methods: Retrospectively, we evaluated the indications for AVGs created at our institution which became infected.

Creation of arteriovenous fistula for hemodialysis in the older population.

Objective: To evaluate the results of arteriovenous fistula (AVF) created for haemodialysis in patients older than 65 years of age.

Subjects And Methods: A retrospective analysis of patients with AVF or arteriovenous graft (AVG) creation, who were older than 65 years of age and were operated on at the II. Surgical Clinic at the University Hospital in Olomouc from 2014 - 2018 was performed.
