Thermographic assessment of perforating arteries. A preoperative screening method for fasciocutaneous and musculocutaneous flaps.

Pre-operative localization of the involved perforating arteries in the planning of musculocutaneous or fasciocutaneous flaps may lead to a higher survival rate of the whole skin island. This in particular will be of importance in donor areas with changed haemodynamics. A noninvasive method is described for the accurate preoperative localization of the perforating arteries of the trunk and extremities; a method which causes minimal discomfort to the patient, but which will help in preparing for a successful operation. We have used this method since 1983 for all high-risk patients, and it has proved to be very useful in our hands.
