Abstract：
UNASSIGNED: The ultrasonic surgical aspirator is widely used in intracranial tumor resection as this instrument is considered safe. The advantage of an ultrasonic surgical aspirator is that it does not damage vessels or nerves close to the tumor. Therefore, limited information exists regarding intraoperative arterial injury by the ultrasonic surgical aspirator.
UNASSIGNED: We report two cases. The first case was a 30-year-old woman who underwent surgery for a recurrent craniopharyngioma, and the second was a 50-year-old man who underwent surgery for a meningioma. A craniopharyngioma encased the basilar artery in the former case, and the superior cerebellar artery was encased by a meningioma in the latter. An ultrasonic surgical aspirator was used to resect the tumors in two cases. During surgery, the arteries involved in the tumors were unintentionally injured using an ultrasonic surgical aspirator. Intraoperative hemostasis was achieved for the bleeding from the injured arteries. However, postoperative digital cerebral angiography revealed pseudoaneurysms in the injured arteries. A subarachnoid hemorrhage occurred in the first case. The pseudoaneurysms were managed using endovascular embolization.
UNASSIGNED: Intraoperative arterial injury can occur with the application of an ultrasonic surgical aspirator. Neurosurgeons should be cautious when using ultrasonic surgical aspirators to avoid damaging the arteries involved with the tumor.

摘要：
■超声外科吸引器广泛用于颅内肿瘤切除术，因为该仪器被认为是安全的。超声外科吸引器的优点是它不会损伤靠近肿瘤的血管或神经。因此,关于超声外科吸引器术中动脉损伤的信息有限。
■我们报告2例。第一个病例是一名30岁的妇女，她因复发性颅咽管瘤接受了手术，第二个是一名50岁的男子，他接受了脑膜瘤手术。在前一种情况下，颅咽管瘤包裹了基底动脉，小脑上动脉被脑膜瘤包裹。使用超声外科吸引器切除2例肿瘤。手术期间,使用超声外科吸引器无意中损伤了肿瘤中的动脉。对于损伤动脉的出血，实现了术中止血。然而,术后数字脑血管造影显示受损动脉有假性动脉瘤。第一例发生蛛网膜下腔出血。使用血管内栓塞治疗假性动脉瘤。
■应用超声外科吸引器会发生术中动脉损伤。神经外科医生在使用超声手术吸引器时应谨慎，以免损伤与肿瘤有关的动脉。
