Abstract

Background and Objective. Meningiomas represent the most prevalent benign intracranial tumors, comprising 13- 26% of primary intracranial neoplasms. These tumors derive their blood supply from both extracranial and intracranial circulation. Over recent decades, pre-operative embolization (POE) has emerged as a potential adjunctive therapy to surgery, aiming to reduce tumor vascularity. Our study seeks to explore the potential correlation between the extent of devascularization following POE of meningiomas and intraoperative blood loss.

Methods. This cross-sectional study involved nine meningioma patients at a tertiary hospital, involving chart review of patients across four years. These patients were referred for POE due to angiographic evidence of a hypervascular mass between January 2018 and January 2022. We collected demographic data, tumor characteristics (including location, size, and vascular supply), and intraoperative variables such as total operative time and blood loss. Statistical analyses aimed to uncover correlations between vascularization degree and various factors.

Results. Our population consists predominantly of females (53.68%), with a mean age of 45.85 ± 13.65 years. Only one mortality was recorded (7.7%). Pre-operative embolization achieved devascularization in the majority (69.2%) of cases, with approximately two-thirds (66.7%) experiencing complete devascularization. Mean total operative time stood at 336.11 ± 301.88 minutes, with a mean post-operative blood loss of 985.56 ± 1013.72 milliliters. Additionally, for those with recorded recovery times, the mean recovery time was 14.32 ± 13.51 hours.

Mortality rates showed no association with sex, devascularization status, or number of feeding vessel zones. Furthermore, the extent of devascularization did not correlate with age, sex, number of feeding vessel zones, postoperative blood loss, total operative time, or recovery time (p >0.05).

Conclusion. In summary, this study represents a significant endeavor to elucidate factors influencing meningioma outcomes following pre-operative embolization. Despite limitations regarding patient numbers, our study offers valuable insights into operative parameters and embolization considerations for future analyses in our tertiary center.
