Abstract [Objective]To explore the efficacy of early microsurgical treatment of ruptured aneurysms of anterior communicating (ACOM ) artery .[Methods] Totally 50 patients with ruptured aneurysms of ACOM artery in our hospital underwent microsurgery through the pterional approach within 48 hours .The imaging characteristics and operation methods were discussed .[Results]The intraoperative diagnosis was consistent with preoperative diagnosis in 50 patients .Among them ,5 patients were multiple aneurysms ,and 3 patients were posterior communicating artery aneurysm ,and 1 patient was middle cerebral artery aneurysm ,which was ipsilateral and occluded by operation for one time ,and 1 patient was C2 segment aneurysm of bilateral carotid artery in which two aneurysms of major lateral carotid artery were occluded by operation for one time and con-tralateral C2 segment aneurysms were observed continuously .The ruptured aneurysms were middle and small aneurysms .After the operation for 6 months ,43 patients were Glasgow outcome scale(GOS) grade Ⅴ ,and 2 patients were grade Ⅳ ,and 1 patient was grade Ⅲ ,and 2 patients were grade Ⅱ ,and 2 patients were gradeⅠ .[Conclusion] Attention to the details and individual management are the critical for the success microsur-gery of ruptured aneurysms of ACOM artery .Early microsurgery for clearing hematocele and occluding aneu-rysms can achieve the satisfactory results .
