摘　　要：目的 :探讨已经结扎的颈外动脉能否通过结扎处或通过结扎处上下血管间形成的侧支循环吻合再通。方法 :1988年 9月至 1995年 4月对 9例严重顽固性老年鼻出血患者施行了颈外动脉结扎术 ,其中 2例分别于颈外动脉结扎后 5年和 7年在结扎侧鼻腔再次出血 ,为明确患者已经结扎的颈外动脉和复发鼻出血之间的关系 ,对患者已经结扎的颈外动脉进行血管数字减影造影。结果 :已经结扎的颈外动脉不会通过双重血管结扎处 ,也不会通过结扎处上下血管形成的侧支循环吻合再通 ,而且在结扎处周围也不可能形成侧支循环的吻合支 ,已经结扎的颈外动脉和复发鼻出血之间没有任何关系。结论 :已经结扎的颈外动脉不会随着时间的推移而重新再通。Objective:To investigate whether the external carotid artery which has been ligated can get repatency through the ligation or the ramus anastomosis of collateral circulation above and below the ligation position.Methods:From September 1988 to April 1995, the external carotid artery had been ligated in 9 patients with severe epistaxis. Among them, 2 patients had recurrence epistaxis in the side of the ligation,of whom 1 recurred on the 5 years after ligation and 1 recurred on the 7 years after ligation.Digital subtraction angiography on the external carotid artery which had been ligated was performed in order to confirm the relation between the ligated external carotid artery and the recurrence epistaxis in the 2 patients.Result: The external carotid artery which had been ligated could not get repatency through the ligation or the ramus anastomosis of collateral circulation above and below the ligation position,and the ramus anastomosis of collateral circulation above and below the ligation couldn′t had formed. The external carotid artery which had been ligated had no relation with the recurrence of epistaxis.Conclusion: The external carotid artery which have been ligated can not get repatency as time goes on.
