Suction blister transplantation for leg ulcers.

Application of suction blister transplants to leg ulcers is an alternative symptomatic treatment to split-skin grafting, i.e. "pinch-grafting". Blisters are produced by the suction device Dermovac at a suction pressure of 250-300 mmHg for 1-2 hours. The blister-roofs are cut off at the periphery and placed on the granulation tissue of the ulcer. The healing time for leg ulcers was 10-14 days. Excellent epithelialization was seen in 10 out of 12 ulcers. The advantages of the method are, that it is easy to perform, no scarring is produced, and the procedure is painless.
