By increasing blood flow to the brain, it lowers stroke risk and boosts thinking skills.
Many patients see big improvements after surgery. They feel better mentally and have less chance of strokes. The surgery is customized for each patient to ensure the best blood flow to affected brain areas. Revascularization surgery for Moyamoya disease uses different techniques to enhance brain blood supply. The choice of method depends on the patient’s health, disease extent, and brain anatomy.
Types of Bypass Surgery
Surgical revascularization for Moyamoya disease uses different bypass techniques. These are chosen based on the patient’s needs.
Bypass surgery for Moyamoya disease falls into two main types: direct and indirect bypass. It’s important for patients and their families to understand these options. This helps them make informed decisions about their treatment.
Direct Bypass Surgery
Direct bypass creates a new blood flow path. It connects a healthy blood vessel to the affected brain area. This method is very effective and can greatly improve outcomes for some patients.
Indirect Bypass Surgery
Indirect bypass promotes the growth of new blood vessels. It places a healthy blood vessel near the affected brain area. This allows natural blood vessel growth to occur.
The choice between direct and indirect bypass depends on several factors. These include the patient’s health, the disease’s extent, and the neurosurgical team’s expertise. Moyamoya disease specialists work with patients to find the best surgical approach.
