Traumatic Aneurysms of the Superficial Temporal Artery – Case Report
淺顳動脈創傷性血管瘤－病例 報告
摘要
淺顳動脈創傷性血管瘤好發於男性，且多於顏面鈍傷害2-6週後發生。在西方國家中常因曲棍球、滑冰、棒球要橄欖球或籃球等運動或汽車事故之鈍傷害而導致淺顳動脈創傷性血管瘤。國內因曲棍球或橄欖球等高速運動較不風行，故此類高速運動鈍傷害造成淺顳動脈創傷管瘤之發生率遠比國外低，但國內騎機車未戴安全帽者眾，所以因機車車禍導致淺顳動脈創傷性血管瘤之發生率則遠較國外高。 多數病例只要透過詳實之病歷記錄及理學檢查即可作出診斷。超音波是一種非侵犯性、具經濟效益，且可重覆實施之診斷工具。常見之鑑別診斷包括動靜脈瘻管、血管腫瘤、中硬腦膜動脈血管瘤合併骨骼侵蝕，脂肪瘤、膿瘍或囊腫等。局部麻醉下進行切除乃是簡易有效之治療方法。在此我們提出5例各式創傷及1例醫緣性淺顳動脈創傷性血管瘤，並對國內血管瘤形成之機轉、大小及特性、好發之年齡及部位和保守及手術治療之比較等經追蹤後做一系列之探討，以增加國內耳鼻喉科醫師對此罕見疾病之瞭解，並建立我國本土文獻以供參考。

Most traumatic aneurysms of the superficial temporal artery (STA) are secondary to a blunt trauma and are seen within 2-6 weeks after injury. Eighty percent of all cases occur in males. All victims in our series are males and most (5/6) are young men. All aneurysms in our cases are pulsatile and sixty-seven percent (4/6) are non-tender. The size of aneurysms varies from 0.5cm to 3 cm in diameter. All aneurysms are seen within 5 weeks after injury and are false aneurysms. Most aneurysms (5/6) are located at the right temporal region (preauricular branch of STA), except one at the right frontal branch. The incidence of the STA aneurysm caused by motorcycle accidents in our cases is higher (33%) than that of the Western countries, due to the fact that motorcycles are a popular form of transportation and many riders do not wear helmets. Eighty percent (4/5) aneurysms can be excised under local anesthesia, except in a child (case 5). Only one patient (case 5) needs a second operation due to a subsequent coagulopathy. Sixty-seven percent (4/6) aneurysms occur in intensive exercises and vehicle racing without a helmet. So we suggested that it should be compulsory for riders to wear a helmet. We present 5 male cases of STA aneurysm caused by various types of trauma and one iatrogenic STA aneurysm. To the best of our knowledge, cases 5 and 6 are the first reports of this kind in the literature.
