Objective:To investigate the emergency surgical effect of ruptured intracranial dural arteriovenous fistula (DAVF).Methods:Patients with ruptured intracranial DAVF underwent microsurgery in the Department of Neurosurgery, Nanping First Hospital Affiliated to Fujian Medical University from May 2013 to July 2022 were retrospectively included. The clinical, imaging and follow-up data were collected, and the clinical characteristics, selection of surgical methods and treatment effects of patients were summarized.Results:A total of 8 patients with DAVF were enrolled. Their age ranged from 11 to 60 years (average, 48 years). There were 7 males and 1 female. All 8 patients suffered from intracranial hemorrhage, manifested as headache and vomiting in 2 cases, simple conscious disturbance in 2 cases, conscious disturbance with cerebral hernia in 3 cases, and conscious disturbance with limb paralysis in 1 case. The fistula was located in the anterior fossa in 4 cases (including 2 cases with aneurysms), the middle fossa in 2 cases (including 1 case with moyamoya disease), the transverse sinus in 1 case, and the anterior 1/3 area of the sagittal sinus in 1 case. Cognard classification: 7 patients were type Ⅲ and 1 was type Ⅳ. After admission, all patients underwent emergency craniotomy and microsurgery to remove hematoma. Among them, 4 patients underwent decompressive craniectomy at the same time, 1 patient with moyamoya disease underwent dural turnover and temporalis muscle application at the same time, and 2 patients with aneurysms at the same location were clipped at the same time. Postoperative re-examination of head CT showed that the hematoma was cleared satisfactorily and the midline was no shift in all 8 patients. CT angiography (CTA) showed that the fistula disappeared within 2 weeks. Seven patients were followed up within 1-12 months after operation. CTA or digital subtraction angiography showed no recurrence of DAVF. Two patients with aneurysms did not have residual or recurrent aneurysms. All patients had no new neurological symptoms, and the Glasgow Outcome Scale score in 2 patients increased by 1 compared with that at discharge.Conclusion:Emergency microsurgery is an effective method for the treatment of ruptured intracranial DAVF, especially for patients with special parts or complicated hematoma, cerebral hernia, and other vascular diseases.
