腹壁下动脉穿支分布特点及扩张穿支皮瓣临床应用

Objective To'explore the distribution of deep inferior epignstric perforator vessel and application of the expanded perforator flap for large sear on hand and forearm. Methods 20 healthy adults were selected to detect the distribution of deep inferior epignstrie perforator vessel. 10 cases with eieatricial constriction on hand and forearm were treated with expanded perforator flap. Results 425 perforator paints were detected on the skin surface of abdomen in 20 adults. 80% of the points are located within the area which is 1.1 ～5.8 cm far from the mid-line of abdomen. According to the Rand method, the percentage of the paints in zone Ⅰ, Ⅱ, Ⅲ were 26%, 43%, and 30%, respectively. There were few points in zone Ⅳ. The area around navel had a high density of points. The paints were distributed asymmetrically at the two sides of abdomen, 10 cases were treated. Vascular deficiency happened at the distal end of one flap. All the other 9 flaps survived. Conclusions The expanded deep inferior epigastric perforator flap is thin and has a large size. It is very suitable for large sear on forearm or hand.
