An Experimental Human DIEP Flap Model to Investigate Preservation Strategies for Vascularized Composite Allografts and Free Flaps

Our study aims to improve preservation and survival of vascularized composite allografts, and free flaps using human experimental flaps models. Current research mainly relies on animal VCA and free flap models, often using rodent or large animal hand/limb osteomyocutaneous flaps. To begin, perform the preoperative dermal lipectomy marking with the patient and identify the midline from the pubic synthesis to the xiphoid process.

Draw a transverse line approximately seven centimeters above the vulvar commissure. Extend this line laterally about seven centimeters on each side, gently curving it upward to join just below the anterior superior iliac spines. Identify the perforators around the umbilicus using a handheld acoustic doppler probe with eight to 10 megahertz while the patient is in the supine position.
