Vessel size discrepancy is a recognized complication associated with free flap anastomosis. This complication occurs when the diameter of the blood vessels from the free flap does not match the diameter of the recipient's blood vessels. Proper anastomosis is crucial for ensuring adequate blood flow to the flap, which is vital for its survival. When there is a mismatch in vessel sizes, it can lead to complications such as thrombosis or inadequate perfusion, ultimately jeopardizing the viability of the flap.

In the surgical setting, careful planning and technique are necessary to avoid such discrepancies, including the selection of appropriate donor sites and vessels. Surgeons may use various strategies, such as the use of tapered anastomosis or the strategic placement of sutures, to address potential size differences and ensure successful implantation of the free flap.
