Extracranial-intracranial microvascular by-pass in the treatment and prevention of cerebral ischemia.
The microanastomosis of a scalp artery to a cortical vessel to augment cerebral blood flow is a significant advance in the treatment of patients with cerebral ischemia due to intracranial arterial obstruction. Results of nearly two thousand cases performed in the world since 1967 show clearly that the operation is excellent in the relief of transient ischemic attacks and in the prevention of iatrogenic stroke. Its place in the long term prevention of strokes is being evaluated. A personal series of 16 patients with 18 microvascular by-passes is reported. The indication, technique and pitfalls of this procedure is illustrated in this local series.
