[Significance of extra-intracranial microanastomoses for cerebral blood flow (author's transl)].
In occlusion and stenosis of the major cranial and cervical arteries supplying the brain with consequent ischemic brain lesions anastomosing extra- and intracranial arteries by microsurgery may dramatically improve deficient brain nutrition. For such extra-intracranial arterial bypass operations (EIAB) well-defined rules were developed both for indications and contraindications and for optimum timing of surgery. EIAB effectively prevents intermittent and threatening irreversible neurologic dysfunction in TIA and PRIND and produces a substantial improvement, at times even a complete restitution of preoperative deficits in cases with completed stroke. Even at an advanced patient age operative morbidity and mortality have been extremely low in the author's experience (operative mortality, 1%; mortality overall 3,5%).
