Arteriovenous fistulae following hair transplantation: collective review and report of a case.

Hair transplantation has become one of the most common cosmetic procedures in men. Complications are reported to be rare. Eight cases of arteriovenous fistulae following the procedure have been recorded in the literature, occurring anywhere from a few weeks to several months after the transplantation. This presentation, the ninth case, is of a 33-year-old man whose procedure was performed in a dermatology clinic and who first saw signs of an enlarged, pulsating blood vessel in the temporal region some 7 weeks later. A photograph of the lesion is presented and the method of treatment of the fistula is described.
