Microvascular bypass procedures for ischemic cerebrovascular disease
Bulletin of the Los Angeles Neurological Societies
|January 1, 1980
Summary
Extracranial to intracranial (EC/IC) bypasses, particularly superficial temporal to middle cerebral artery (STA-MCA) grafts, offer treatment for cerebral ischemia. These procedures can reduce transient ischemic attacks (TIAs) in select patients, with ongoing studies evaluating long-term stroke protection.
Area of Science:
- Neurosurgery
- Vascular Surgery
- Neurology
Background:
- Cerebral ischemia resulting from inaccessible cerebrovascular disease, such as carotid artery and middle cerebral artery occlusion/stenosis, necessitates advanced treatment strategies.
- Extracranial to intracranial (EC/IC) microvascular bypass grafting is increasingly employed to address these challenging conditions.
Purpose of the Study:
- To discuss the patency rates, potential complications, and established indications for superficial temporal to middle cerebral artery (STA-MCA) bypass.
- To highlight the role of EC/IC bypasses in managing cerebral ischemia and preventing cerebrovascular events.
Main Methods:
- Review of current surgical techniques and outcomes for EC/IC bypass procedures.
- Discussion of clinical evidence supporting the use of STA-MCA bypass for specific cerebrovascular pathologies.
Main Results:
- EC/IC bypasses have demonstrated the ability to significantly reduce or completely arrest transient ischemic attacks (TIAs) in carefully selected patient cohorts.
- The long-term efficacy of a functioning STA-MCA bypass in providing stroke protection is currently under extensive multinational investigation.
Conclusions:
- Superficial temporal to middle cerebral artery (STA-MCA) bypass is a viable option for treating cerebral ischemia caused by inaccessible cerebrovascular disease.
- Further research, including multinational controlled trials, is essential to fully elucidate the long-term stroke protective benefits of STA-MCA bypass.
