医源性视网膜中央动脉栓塞

IATROGENIC CENTRAL ARTERY EMBOLISM

本文报告三例头颈部注射药物后引起视网膜中央动脉栓塞,其中二例是由于药物中混悬液进入视网膜中央动脉内形成栓子,造成动脉栓塞。另一例是由于造影剂快速、大量进入颈内动脉再进入视网膜中央动脉,使全视网膜动脉均为造影剂充盈,短时间内使视网膜缺血、缺氧而致失明。

This paper presented 3 cases of central retinal artery embolism (CRAE) caused by the drug injection at the head and neck.In two of the three cases,the emboli were formed by the suspended drug which entered CRA resulting in the occlusion.Another case was caused by the large amount of meglucaminidiatrizoas which was injected too quickly during angiography.The CRA was filled up with fluorescein in a very short time, which lead to ischemia and hypoxia of the retina. This paper stressed the importance of early diagnosis and prompt treatment.The authors also Discussed the method of drug injection at the head and neck.
