DIEP flap
Pronunciation: DEEP flap
Also written as: DIEP — Deep Inferior Epigastric Perforator
Deep inferior epigastric perforator flap used for breast reconstruction without sacrificing muscle.
Full Definition
The DIEP flap (Deep Inferior Epigastric Perforator) is an advanced microsurgical technique for breast reconstruction that uses skin and fat from the lower abdomen while preserving the underlying rectus abdominis muscle. Unlike the TRAM flap, the DIEP flap technique carefully dissects around muscle fibers to harvest only the perforating blood vessels, resulting in reduced donor site morbidity and decreased risk of abdominal wall weakness. The procedure requires extensive microsurgical expertise to connect the flap's blood vessels to recipient vessels in the chest. Recovery time is typically longer than implant-based reconstruction but provides a more natural breast contour using the patient's own tissue.
Usage
Usage note: Always spell out the full form on first use in documentation.
