Vascular Preoperative Venous Mapping Decreases the Frequency of Negative Exploration in Arteriovenous Fistula Creation
Journal Title: Journal of Islamabad Medical and Dental College - Year 2017, Vol 6, Issue 3
Abstract
Objective: To assess the impact of preoperative venous mapping on the incidence of negative exploration for arteriovenous fistula (AVF) in patients requiring hemodialysis. Patients and Methods: This case control study was conducted in Department of Vascular Surgery Combined Military Hospital Lahore and Peshawar, from January 2016 to June 2016. A total of 200 consecutive patients fulfilling the inclusion criteria were divided into Case (with preoperative mapping) and Control (without mapping) groups. Negative exploration rate along with fistula maturation rates were recorded and compared. Results: In Control group 24% patients had negative exploration when compared with 0% in Case group (p-value 0.000). In Case group, 16 % patients had change in type and site of AVF based on the results of venous mapping hence bringing down the negative exploration rate to zero in this group. Conclusion: Routine preoperative venous mapping decreases negative exploration in AVF creation and is helpful in deciding the best site and type of AVF.
