A variety of cerebral vascular anomalies are widely applied, however anomalies of the middle cerebral artery (MCA) are relatively infrequent. The duplicated MCA (DMCA) is a MCA anomaly. Aneurysm arising from the origin of the DMCA is rare. Cerebral angiography in a 61-year-old female demonstrated a small (about 3 mm) saccular aneurysm located at the origin of the DMCA in the anterior direction. Considering the unusual location, the lesion was treated, regardless of the size. Aneurysmal characteristics of a broad neck and small size limited the endovascular approach, necessitating open surgery. Her postoperative course was uneventful and postoperative angiography showed complete obliteration of the aneurysm. The patient was discharged without neurologic deficit.
多种脑血管畸形被广泛应用,然而大脑中动脉(MCA)畸形相对少见。双大脑中动脉(DMCA)是一种MCA畸形。起源于DMCA的动脉瘤罕见。一名61岁女性的脑血管造影显示一个小(约3毫米)的囊状动脉瘤位于DMCA起始部向前方向。考虑到其不寻常的位置,无论大小,该病变均接受了治疗。宽颈和小尺寸的动脉瘤特征限制了血管内治疗方法,因此需要进行开放手术。她的术后过程顺利,术后血管造影显示动脉瘤完全闭塞。患者出院时无神经功能缺损。
