Microsurgical removal of suprasellar meningiomas
Abstract:
The authors report 17 cases of large suprasellar meningiomas operated on during the 2-year period from February 1982 through March 1984. The tumors ranged from 4 to 9 cm in diameter. These patients presented with severe visual loss (4 were blind) and optic atrophy or papilledema. These tumors were noteworthy in their encroachment against and around the carotid arteries and optic nerves laterally, as well as against the hypothalamus with extension into the interpeduncular cistern and frontal fossa. Advanced microsurgical technique assisted in total removal of all tumor tissue with preservation of vital structures. There were three deaths: two from pulmonary embolism and one from gastrointestinal hemorrhage. The surgical technique for the total removal of these very large tumors is described.
Insights
This study details 17 cases of large suprasellar meningiomas, emphasizing advanced microsurgical techniques for total tumor removal and preservation of vital structures in patients with severe visual loss.
Area of Science:
- Neurosurgery
- Oncology
Background:
- Suprasellar meningiomas are tumors that grow near the optic nerves and brain.
- Large tumors can cause significant visual impairment and neurological deficits.
Purpose of the Study:
- To describe the surgical management and outcomes of 17 patients with large suprasellar meningiomas.
- To highlight the microsurgical techniques used for complete tumor resection.
Main Methods:
- Retrospective review of 17 surgically treated large suprasellar meningiomas (4-9 cm).
- Application of advanced microsurgical techniques for tumor removal.
- Focus on preserving critical neurovascular structures.
Main Results:
- Complete tumor removal was achieved in all cases.
- Patients presented with severe visual loss, optic atrophy, or papilledema.
- Three surgical deaths occurred (pulmonary embolism, gastrointestinal hemorrhage).
Conclusions:
- Advanced microsurgical techniques enable total resection of large suprasellar meningiomas.
- Careful surgical planning is crucial for preserving neurological function.
- Despite risks, microsurgery offers a viable treatment option for these complex tumors.
