目的：对前交通动脉瘤的脑血管造影结果进行分析。材料与方法：采集我院近年来全部经手术证实的２２例前交通动脉瘤的脑血管造影，并以随机选出的非前交通动脉瘤的２５０例脑血管造影为对照组。结果：２５０例对照组的脑血管造影的血管形态、走行基本正常，而２２例前交通动脉瘤的脑血管造影的血管形态及走行则全部表现为作者提出的“易形成前交通动脉瘤的血管模式”，即：一侧前动脉第一段缺如、闭塞或纤细，另一侧颈内动脉则通过开放的前交通动脉同时供应双侧前动脉。结论：（１）如ＣＴ检查示鞍上池或纵裂出血，脑血管造影具有此模式的影像改变，即使脑血管造影未见明确的动脉瘤改变，也应考虑前交通动脉瘤的存在。（２）如脑血管造影为此模式，即使无蛛网膜下腔出血，亦应警惕前交通动脉瘤的发生，并注意随访。
Objective: To analyze the results of cerebrovascular angiography of anterior communicating aneurysms. Materials and Methods: Cerebral angiography of 22 cases of anterior communicating aneurysm confirmed by operation in our hospital in recent years was collected. The control group consisted of 250 cases of cerebral angiography of non-communicating artery aneurysm randomly selected. Results: Cerebral angiography of 250 control subjects showed basically normal vessel morphology and blood vessel morphology and pathology of 22 angiocardiographic anterior communicating aneurysms. All the results showed that the vascular morphology of the anterior communicating artery aneurysm Mode ", namely: the first section of the anterior artery is absent, occluded or slender, and the other side of the internal carotid artery supplies the bilateral anterior artery through the open anterior communicating artery at the same time. CONCLUSIONS: (1) Cerebral angiography has an image change in this mode of imaging if the CT scan shows a suprasellar or longitudinal splitting hemorrhage. The presence of the anterior communicating artery aneurysm should also be considered, even if no definite aneurysm changes are detected in the cerebrovascular angiography. (2) such as cerebral angiography for this mode, even without subarachnoid hemorrhage, should also be alert to the occurrence of anterior communicating aneurysms, and pay attention to follow-up.
