Intracranial arterial dolichoectasia (or dilatative arteriopathy) is characterized by abnormal elongation, tortuosity, or increase in diameter of at least one of the main cerebral vessels. Dolichoectasia can be found incidentally or can present with cranial neuropathies (including vision loss) or stroke. Here, we describe the presentation and open surgical treatment of a patient with dolichoectasia of the intracranial internal carotid artery (ICA) causing monocular vision loss.
A 73-year-old man presented with several months of progressive monocular vision loss and was found to have dolichoectasia of the supraclinoid ICA and subsequently underwent microsurgical decompression of the overlying affected optic nerve. The patient's postoperative convalescence was uncomplicated, and he had improvement in his right-sided monocular vision loss after surgery.
We present the case of a patient with dolichoectasia of the supraclinoid ICA causing compression of the optic nerve with resultant monocular vision loss. Timely microvascular decompression proves to be an effective technique for vision preservation in the setting of this rare pathologic entity.
颅内动脉迂曲扩张（或扩张性动脉病）的特征是至少一条主要脑动脉异常伸长、迂曲或直径增加。迂曲扩张可偶然发现，也可表现为颅神经病变（包括视力丧失）或中风。在这里，我们描述了一位颅内颈内动脉（ICA）迂曲扩张导致单眼视力丧失的患者的表现和开放手术治疗。
一名 73 岁男性出现数月进行性单眼视力丧失，发现存在颅底 ICA 迂曲扩张，随后接受了受影响视神经上方的显微减压手术。患者术后恢复顺利，术后右侧单眼视力丧失得到改善。
我们报告了一例因颅底 ICA 迂曲扩张导致视神经受压而导致单眼视力丧失的病例。及时的微血管减压术被证明是治疗这种罕见病理实体导致视力丧失的有效方法。
