Congenital or nonatherosclerotic dolichoectasia is a rare condition; its etiology, natural history, and indications and technique of treatment are not yet clarified. During a workup for recent headaches and left-sided paresthesia in a 48 year-old female patient, brain MR imaging and cerebral angiography showed a large dolichoectasia of the P2 segment of the right posterior cerebral artery (PCA). The patient passed endovascular testing for occlusion of P2 with both balloon test occlusion and selective amytal testing. Endovascular coil occlusion of the right PCA dolichoectasia was successfully performed with hydrogel coils.
先天性或非动脉粥样硬化性颅内动脉扩张症是一种罕见疾病；其病因、自然病史以及治疗指征和技术尚未明确。在对一名48岁女性患者近期头痛和左侧感觉异常进行检查期间，脑部磁共振成像和脑血管造影显示右侧大脑后动脉（PCA）P2段有一大段颅内动脉扩张。该患者通过球囊试验闭塞和选择性阿米妥试验进行P2段闭塞的血管内测试。使用水凝胶弹簧圈成功地对右侧PCA颅内动脉扩张症进行了血管内弹簧圈闭塞术。
