Deep inferior epigastric perforator flap reconstruction
Deep inferior epigastric perforator flap (DIEP) reconstruction is a type of breast reconstruction surgery. It essentially involves the transfer of the patient's own skin and subcutaneous tissues from the lower abdominal wall to the chest to form the breast mound.
The operation spares the rectus muscle, which results in fewer complications and a faster return to normal activities.
The normal glandular breast parenchyma appears replaced by abdominal adipose tissue. Preliminary CT angiography of the inferior epigastric arteries is also often required for surgical planning.
- fat necrosis: reported to occur in around 6-18% of cases 2.
- hematoma +/- seroma formation
- vascular compromise: can occur from either arterial or venous compromise and can lead to flap failure
- tumor recurrence within or around the flap
- donor site complications: e,g, hernia
