[Blood circulation of the "super-thin" skin flap with preserved subdermal vascular network and its clinical application].
摘要
For the study of the blood circulation of the superthin skin flap, arterial perfusion of Chinese black ink was performed in 24 cadavers. From 1984 to 1990, "super-thin" skin flap transplantations have been done in 18 patients with deep injuries as a result of electric contact burn, wringer injuries, or chemical burns. The flap taken from thoracic, abdominal, or upper arm regions was trimmed before transfer, and 2 mm thickness of fat was left attached to the subdermal vascular network. The largest super-thin skin flap of the inguinal region was 7 cm in breadth at the pedicle, 15 cm in length and 20 cm in width at the distal part. All of these flaps survived after transfer. Division of the pedicles was performed 3-5 days postoperatively. The cosmetic and functional results were all satisfactory.
