The cerebellar hemangioblastoma (CHB) has an abundant blood supply and deep anatomical location. Complete surgical resection is generally very difficult. This study investigated the safety and effectiveness of preoperative embolization followed by surgical resection of CHB in a large cohort of patients. A database of 125 CHB patients with surgical resection in Beijing Tiantan Hospital between July 2006 and July 2012 was reviewed. Of those, 46 cases (experimental group) received preoperative embolization, 79 cases (control group) underwent surgery without embolization. Patient demographics, tumor size, duration of surgery, blood loss, blood transfusion, complications and follow-up results were collected and analyzed retrospectively. In the experimental group, the Kamofsky score (KS) was 80-100 in 40 cases (86.9%), 40-70 in 4 cases (8.7%), and below 40 in 2 cases (4.3%). Among 31 cases with follow-up, KS was 80-100 in 27 cases (87.1%), 40-70 in 2 cases (6.5%), and 0 in 2 cases (6.5%). In control group, KS was 80 -100 in 65 cases (82.2%), 40-70 in 6 cases (7.6%), 10-30 in 3 cases (3.8%), and 0 in 3 cases (3.8%). Among 53 cases with follow-up, KS was 80-100 in 44 cases (83.0%), 40-70 in 4 cases (7.5%), 10-30 in 1 case (1.9%), and 0 in 4 cases (7.5%). There were statistically significant differences between the experimental and control groups in tumor size, duration of surgery, amount of intraoperative blood loss and transfusion (p<0.01). However, complications (p=0.31) and follow-up results (p=0.76) showed no significant differences between groups. Selective preoperative embolization of those CHB patients with richer blood supply, higher hemorrhage risk, is safe and effective, and is a reliable adjuvant therapy for complete surgical resection of CHB.
