The DIEP flap takes much longer than a TRAM flap. Doesn that increase the risk?
No. All of this surgery is skin and subcutaneous surgery that is very superficial. The surgery is done on the surface of the abdomen and chest and not inside of these areas. The body interprets the loss of the abdominal muscle (in a TRAM flap) as a major insult. This prolongs recovery much more than a careful surgery that does less harm to the body.
