Moyamoya Disease: Available Treatment Options
Moyamoya disease is a long-term condition that disrupts brain blood flow. Proper medical and surgical treatments are essential to manage it. This overview covers options to enhance circulation and reduce stroke risk.
Medical Treatment
Doctors prescribe medication for Moyamoya disease, such as aspirin to reduce blood clots and calcium channel blockers to relieve headaches and spasms.
However, medicine alone often isn’t sufficient; surgery is frequently necessary to provide additional support.
Methods of Revascularization
Surgery is essential for managing Moyamoya disease by restoring blood flow. The two primary procedures are direct and indirect revascularization.
Direct revascularization creates a bypass by connecting a scalp artery to a brain artery, quickly enhancing blood flow and reducing stroke risk.
Indirect revascularization promotes the development of new blood vessels gradually. Procedures like EDAS, EMAS, and burr hole surgery are used to enhance blood flow to the brain over time.
| Revascularization Technique | Procedure | Benefits | Considerations |
|---|---|---|---|
| Direct Revascularization | STA-MCA Bypass | Immediate blood flow restoration | Technically demanding, requires experienced surgeons |
| Indirect Revascularization | EDAS, EMAS | Stimulates new vessel growth | Variable time for effectiveness, less immediate |
Selecting between medicine and surgery depends on the patient’s needs, with a team of doctors collaborating to provide optimal care. Insights into Surgery and Anesthesia for Moyamoya Disease
