There are many potential anatomical variations in the connection between the internal carotid artery and the posterior circulation through the posterior communicating artery (PCoA). We describe the endovascular treatment of an aneurysm arising near the origin of the PCoA belonging to a transitional type posterior cerebral artery. Coil embolization subsequently resulted in thrombo-occlusion of the adjacent PCoA causing thalamic infarction even though sufficient retrograde flow had been confirmed pre-operatively by Allcock's test.
颈内动脉通过后交通动脉(PCoA)与后循环之间的连接存在许多潜在的解剖变异。我们描述了一例起源于属于过渡型大脑后动脉的PCoA起始部附近的动脉瘤的血管内治疗。尽管术前通过奥尔科克试验已确认有足够的逆行血流,但弹簧圈栓塞随后导致相邻PCoA血栓形成闭塞,引起丘脑梗死。
