Morphometrical study of the arterial perforators of the deep inferior epigastric perforator flap.

摘要: Although abdominal perforator flaps based on a cutaneous branch of the deep inferior epigastric artery (DIEP flaps) have many advantages, preparing these is technically difficult and requires great skill, especially as portion running under anterior rectus abdominis sheath must be operated upon "blind". To allow easier preparation elevation DIEP flap pedicle, we propose that arterial should: 1) more than 1.0 mm large; 2) run straight intramuscular course, parallel to m. fibers, with no large muscular branches; 3) only short immediately sheath. We examined 329 perforators (more 0.5 in diameter at sheath) 66 mm. from 33 cadavers among them: 52 "large" were over diameter; 107 "suitable" ran muscle fibers without giving off 35 "ideal" combined characteristics. The ideal usually located mid-abdominal region, 10-30 lateral umbilicus. suitable present, often combination perforator(s), restricted area 20 cranial 40-50 classified course ramification pattern a. into six patterns, depending whether anastomosis was sited medial or level which branches originated.
