Abstract: Objective To summarize the treatment experiences and long-term surgical efficacy of spinal hemangioblastomas.Methods The surgical experiences of 46 patients with spinal hemangioblastomas were analyzed retrospectively.All patients underwent microsurgical resection without preoperative embolization, and 52 operations were performed and 58 tumors were resected.McCormick classification was used to evaluate the function of spinal cord.The mean follow-up time was 8 years.Results Total tumor resection was achieved in 55 tumors and subtotal ones in 3.A week later, improvement was obtained in 11 cases, no changes in 29 and aggravation in 6.No patients died.During a follow-up period from 7 to 9 years, the spinal function was improved in 18 patients, remained stable in 21 and deteriorated in 7.No tumor recurrence was found.The subtotal resection affected the prognosis (P =0.08, OR =10.8, 95 ％ CI 2.1-60.8).Conclusions The spinal hemangioblastomas are highly vascularized benign tumors that can be surgically cured under microscope.Subtotal resection is a risk factor of prognosis.
