Summary
3D-TOF MRA-guided middle cerebral artery contouring significantly improves insular glioma resection. This technique enhances tumor removal, reduces neurological deficits, and improves patient survival rates compared to traditional methods.
Area of Science:
- Neurosurgery
- Neuroradiology
- Oncology
Background:
- Insular gliomas pose surgical challenges due to proximity to critical neurovascular structures.
- Accurate delineation of the middle cerebral artery (MCA) is crucial for safe and effective tumor resection.
Purpose of the Study:
- To evaluate the clinical efficacy of middle cerebral artery (MCA) contouring guided by 3D-time-of-flight Magnetic Resonance Angiography (3D-TOF MRA) in the surgical resection of insular gliomas.
Main Methods:
- A retrospective analysis of 67 patients with insular gliomas treated between January 2017 and February 2021.
- Patients were divided into an observation group (3D-TOF MRA-assisted MCA contouring) and a control group (standard microsurgery).
- Comparison of extent of tumor resection (EOR), postoperative neurological dysfunction, Karnofsky Performance Status (KPS), progression-free survival (PFS), and overall survival (OS).
Main Results:
- The observation group achieved a significantly higher EOR (72.2%) compared to the control group (32.3%) (P < 0.001).
- Surgery-related neurological dysfunction was lower in the observation group (8.33%) versus the control group (35.6%) (P = 0.001).
- The observation group demonstrated improved 3-year PFS (31.6 months) and OS (33.5 months) compared to the control group (PFS: 15.3 months, OS: 19.8 months) (P < 0.05).
Conclusions:
- Preoperative 3D-TOF MRA effectively visualizes MCA anatomy, guiding surgical contouring of critical vessels.
- This approach facilitates safer and more effective insular glioma resection.
- The technique reduces postoperative neurological deficits and enhances long-term patient prognosis.
