Objective: To evaluate the effect of hybrid operation suite in the treatment of cerebral and spinal vascular diseases and intracranial hypervascular tumors. Methods: A retrospective study was conducted on 132 patients with various cerebral and spinal vascular diseases and intracranial hypervascular tumors who were treated by hybrid surgery at Department of Neurosurgery, Huashan Hospital from October 2016 to December 2017.There were 70 male and 62 female patients with a mean age of 48.33 years (range: 14-78 years), including 64 cases of intracranial aneurysm (41 complicated aneurysm cases), 28 cases of brain arteriovenous malformation (BAVM), 12 cases of hypervascular tumor, 12 cases of dural arteriovenous fistula (DAVF), 6 cases of carotid artery stenosis, 5 cases of Moyamoya disease, 3 cases of intracranial aneurysm or BAVM combined with tumor, 1 case of scalp arteriovenous fistula and 1 case of critical brain trauma in which a foreign metal stick approached the basal vascular circuit.Abnormalities were found in 16 cases in intraoperative angiography. The clinical data of all patients was collected as a perspective cohort. The success rate of hybrid surgery, intra-operative and post-operative complications, morbidity, mortality, rate of infection, the length of hospital stay were all analyzed to illustrate the effect of hybrid operation mode to traditional surgical pattern. Results: For 64 cases with intracranial aneurysms, the immediate complete occlusion rate was 90.5%, with a mortality of 4.7% and a morbidity of 14.0%. For 28 cases of BAVM and 12 cases of DAVF, all patients achieved total obliteration and favorable social independent outcomes after hybrid surgery, with no complication.For 6 cases of carotid artery stenosis and 5 cases of Moyamoya, intra-operative confirmed good cerebral reperfusion without any new post-operative neurologic deficits. After tumor vessels embolization, 4 out of 12 cases of hypervascular tumor needed intra-operative blood transfusion, and all patients achieved total tumor resection in a single stage. Only one patient with medulla oblongata hemangioblastoma died 6 months after operation due to respiratory deficit related pneumonia. Compared to traditional surgeries, the hybrid operation pattern did not significantly increase the total infection rate, central nervous system infection rate, hospital stay days and post-operative hospital stay days (all P> 0.05) while the in-patient cost increased mildly (119 332 yuan vs .98 215 yuan, t= 2.38, P= 0.02). Conclusions: The operations of complex cerebral and spinal vascular diseases and intracranial hypervascular tumors can be performed in hybrid operation suite safely.This surgical mode can ensure the quality of operation and promote the development of innovative and complicated surgical procedures.
