Comparative StudyLocating perforator vessels by dynamic infrared imaging and flow Doppler with no thermal cold challenge.
Dynamic Infrared Imaging (DIRI) is a noninvasive technique that precisely analyzes the infrared radiation of any object. We used this technique to locate the dominant perforator vessels in flap surgery in conjunction with conventional Doppler. ⋯ DIRI produces a skin thermographic map of perforator vessels and their perfusion area. Handheld Doppler locates perforators at the aponeurotic level. Their combination increases safety in the planning of perforator flap surgery.
