Distal anterior cerebral artery aneurysms are infrequent. The most common location is at the bifurcation of the pericallosal and callosomarginal arteries. Cerebral artery anomalies can sometimes, at least partially, explain aneurysm formation in less common locations in relation to hemodynamic stress caused on the vascular wall. We report a very rare case of subarachnoid hemorrhage due to a ruptured frontopolar artery aneurysm as a part of an anomalous anterior cerebral artery complex that was, for the first time, treated with endovascular coiling.
大脑前动脉远端动脉瘤并不常见。最常见的位置是胼周动脉和胼缘动脉的分叉处。脑动脉异常有时至少可以部分解释在血管壁上由血流动力学应力导致的不常见位置的动脉瘤形成。我们报告了一例非常罕见的蛛网膜下腔出血病例，病因是额极动脉动脉瘤破裂，该动脉瘤是异常大脑前动脉复合体的一部分，首次采用血管内栓塞治疗。
