１９９１年１月～１９９４年３月，我们对９１例病人共９９个脑动脉瘤夹闭术后常规行脑血管造影。造影发现动脉瘤残留者５例（５％），动脉瘤完全未夹闭者１例（１％），载瘤动脉闭塞者１２例（１２％）。手术后造成动脉瘤残留的原因主要与动脉瘤的部位、大小、蒂的宽窄以及手术中动脉瘤的破裂等有密切关系。术者对动脉瘤以及载瘤动脉是否被夹闭往往有误，故不能替代手术后的脑血管造影。动脉瘤残留和血管闭塞术后可以是无症状的，必需靠术后行脑血管造影发现，这样才能对其进行必要的和适当的处理，从而降低脑动脉瘤术后的死亡率和致残率。
From January 1991 to March 1994, we performed routine cerebrovascular angiography in a total of 99 cerebral aneurysms in 91 patients. Angiography showed aneurysm residual in 5 cases (5%), aneurysm completely unclosed in 1 case (1%), in 12 cases of parent artery occlusion (12%). Aneurysm caused by surgery after the main causes and the location of aneurysms, size, pedicle width and aneurysm surgery is closely related to the rupture. Surgery on the aneurysm and the parent artery is often caught in the wrong, it can not replace postoperative cerebral angiography. Aneurysm residual and vascular occlusion may be asymptomatic after surgery, cerebral angiography must be found after surgery, so as to carry out the necessary and appropriate treatment, thereby reducing the mortality and morbidity after cerebral aneurysm surgery .
