BACKGROUND
Posterior communicating artery (PCoA) aneurysms are most commonly located at the junction of the internal carotid artery and the PCoA. "True" PCoA aneurysms, which originate from the PCoA itself, are rarely encountered. Most previously reported cases were treated surgically mainly before the endovascular option became available.
CASE DESCRIPTION
A 53-year-old male presented with sudden onset of right hemiparesis and aphasia. Left middle cerebral artery stroke was diagnosed. Further studies revealed a 3 mm left PCoA aneurysm arising from the PCoA itself, attached to neither the internal carotid artery nor the posterior cerebral artery. Endovascular treatment was performed and the aneurysm was coiled completely.
CONCLUSION
Technical advances in endovascular interventional technology have permitted an additional approach to these lesions. The possible endovascular significance of the treatment of true PCoA aneurysms is discussed.
背景
后交通动脉（PCoA）动脉瘤最常见于颈内动脉与后交通动脉的交界处。起源于后交通动脉本身的“真性”后交通动脉瘤很少见。大多数先前报道的病例主要在血管内治疗方法出现之前接受手术治疗。
病例描述
一名53岁男性突发右半身轻瘫和失语。诊断为左大脑中动脉卒中。进一步检查发现一个3毫米的左后交通动脉瘤，起源于后交通动脉本身，既不附着于颈内动脉也不附着于大脑后动脉。进行了血管内治疗，动脉瘤完全栓塞。
结论
血管内介入技术的技术进步为这些病变提供了另一种治疗方法。讨论了真性后交通动脉瘤治疗的可能血管内意义。
