Introduction:
The primary and definitive diagnosis of meningioma is based on histological assessment; however, employing imaging methods, like Magnetic Resonance Imaging (MRI) is very helpful to describe lesion's characteristics. Accordingly, we decided to study the effect of imaging factors, like MRI data on the volume of hemorrhage (estimated blood loss) during meningioma surgery.
Methods:
This was a cross-sectional, retrospective, and analytical study. The eligible patients were those with meningioma who were candidates for surgery. A total of 40 patients with meningioma were selected and assessed. The preoperative imaging findings were recorded, then estimated blood loss during the surgery was determined.
Results:
A reverse association was revealed between the degree of proximity to the nearest sinus and the rate of bleeding. Furthermore, the size of the mass was positively associated with the rate of bleeding; however, there was no significant correlation between the volume of bleeding and other parameters, including the degree of edema, the volume of mass, the site of the tumor in the brain, and the histological subtype of the tumor. The mean time of operation was strongly correlated with blood loss. The rate of bleeding was more expected in hypertensive versus normotensive patients.
Conclusion:
Bleeding in various volumes could be a frequent finding in intracranial meningioma surgery. Overall, tumor size, the duration of surgery, a history of hypertension, and distance to the nearest sinuses were the main determinants for the severity of hemorrhage in patients undergoing meningioma surgery.
Insights
Magnetic Resonance Imaging (MRI) can predict bleeding during meningioma surgery. Larger tumors, longer operation times, hypertension, and proximity to sinuses increase blood loss in meningioma patients.
Area of Science:
- Neurosurgery
- Radiology
- Oncology
Background:
- Meningioma diagnosis relies on histology, but Magnetic Resonance Imaging (MRI) aids in characterizing lesions.
- Understanding factors influencing intraoperative bleeding is crucial for surgical planning and patient safety.
Purpose of the Study:
- To investigate the correlation between preoperative imaging characteristics, particularly MRI findings, and estimated blood loss during meningioma surgery.
- To identify key determinants of hemorrhage volume in patients undergoing meningioma resection.
Main Methods:
- A cross-sectional, retrospective analytical study involving 40 patients with meningioma undergoing surgery.
- Preoperative imaging findings were recorded, and estimated blood loss during surgery was quantified.
Main Results:
- Tumor size and proximity to the nearest sinus were significantly associated with bleeding volume.
- Longer operative duration and a history of hypertension were strongly correlated with increased blood loss.
- No significant correlation was found between bleeding volume and tumor edema, mass volume, tumor location, or histological subtype.
Conclusions:
- Intracranial meningioma surgery can involve significant blood loss.
- Tumor size, surgical duration, patient history of hypertension, and proximity to sinuses are primary predictors of hemorrhage severity.
