Question 1

Define and explain the significance of vascular anastomoses.

Accepted Answer

A vascular anastomosis is a ʺcoming togetherʺ of either arteries or veins. Vascular anastomoses are alternative pathways for blood flow. These pathways are called collateral channels. Arterial anastomoses often occur around joints providing alternative pathways for blood to flow when movement of a joint impinges upon flow through other vessels. The anastomosis ensures adequate perfusion of the tissue.
Venous anastomoses provide multiple pathways for drainage. Blockage of a single vein rarely blocks blood flow or leads to tissue death.
