Clinical analysis of intracranial hemangioblastomas treated by microsurgery combined with preoperative in-terventional embolization and its related problems / 中华显微外科杂志

ABSTRACT

Objective To investigate the clinical effect of microsurgical resection combined with preoperative interventional embolization in the treatment of solid intracranial hemangioblastomas, and to analyze the effect of pre-operative embolization on tumor resection,and to discuss the surgical technique and perioperative management of mi-crosurgery. Methods From September, 2010 to September, 2015, the clinical signs, preoperative embolization, mi-crosurgery and prognosis of 18 patients with solid hemangioblastomas were retrospectively analyzed. The patients were examined by CTA and MRI,18 patients underwent DSA tumor arterial embolization and tumor microsurgery. Results The tumor diameter was 2.5-4.0 cm, the proportion of preoperative embolization tumor was 100% in 4 cases, 80% -95% in 9 cases,60%-70% in 3 cases and 60% in 2 cases.16 cases(88.9%)were subtotal tumors,2 cases(11.1%) were subtotal resection, 1 case died. No patients with intraoperative blood transfusion.followed up for 2 years without tumor recurrence. Conclusion The risk of postoperative hemangioblastomas is high, and the intervention of em-bolization for tumor artery will reduce the risk of operation.Microsurgery is the preferred treatment,and skilled micro-surgery is the key to treatment.
