外傷性深側頭動静脈痩の1治験例

Traumatic AV Fistula of The Deep Temporal Artery:A case report

I．はじめに

　側頭部に発生した頭皮下動静脈旗としては，外傷性浅側頭動静脈瘻が最も多く報告されているが，深側頭動脈を流入動脈とする動静脈瘻は稀である．われわれは外傷後に症状が発現した，深側頭動脈を主な流入動脈とする動静脈瘻の1症例を経験したので，若干の文献的考察を加えて報告する．

A rare case of traumatic AV fistula of the deep tem-poral artery is reported. The patient, a 33 years old male, struck his forehead and left temporal region in a traffic accident on March 30, 1983. He noticed the swelling at his temporal region 5 days after the accident as it became pulsative and enlarged.

He was admitted on May 23 and left external carotid angiography revealed an AV fistula which was fed by the deep temporal artery and drained into the superficial temporal vein. The operation was performed on May 27 and showed that the AV fistula was not in the subcutaneous tissue, but buried in the temporal muscle.
