Solution to vessels mismatch in microsurgery: Vertical arteriotomy technique.

ABSTRACT:

Background

Microvascular anastomosis is the key for successful free flap transplantation. Ideally, the anastomosis should maintain the flow with minimal turbulence, disruption of endothelium, and minimizing the furrow to prevent thrombosis and failure of the flap. One of the main pitfalls of micro-anastomosis is vessels size mismatch.

Method and result

There are many ways to overcome this issue, which includes forced mechanical dilation of the smaller vessel, oblique cuts, fish mouth cuts, interposition grafts, end-to-side anastomosis, coupling device, and others. Here, we report a simple technique with single customizable longitudinal arteriotomy of the smaller vessel to achieve an adequate size match to the larger vessel. It has been used for more than 10 years at our inst
