Blood Flow Capacity Assessment of End-to-Side Arterial Anastomosis In Vivo in Rats

Abstract

Introduction The aim of this article was to assess the flow capacity of end-to-side arterial anastomosis depending on the method of its implementation.

Materials and Methods The study was conducted on 30 live Wistar rats in vivo, which were randomly divided into three groups. In each group of animals, an end-to-side microanastamosis was performed using three methods of donor artery preparation: 45 degrees (group A), 90 degrees (group B), and arteriotomy according to the “fish mouth” type (group C). The determination of flow capacity of anastomosis by measuring the blood volume flow with transonic flowmeter was performed.

Results The obtained average values after the anastomosis were, respectively, 7.335 mL/s (standard deviation [SD]: 2.0771; min: 4.05; max: 10.85), 7.36 mL/s (SD: 0.836 mi: 6.15; max: 8.75), and 6.37 mL/s (SD: 1.247; min: 5.05; max: 9.05). No statistically significant difference in the blood volume flow velocity between all types of anastomoses was obtained (p = 0.251).

Conclusion The flow capacity of end-to-side arterial anastomosis does not depend on the chosen method of anastomosis.
