Stereotaxic coagulation of a paraventricular arteriovenous malformation

Abstract

✓ Stereotaxic coagulation of a single feeding vessel to a deeply situated arteriovenous malformation is described. The procedure involves stereotaxic positioning of a coagulating electrode to the arterial supply of the malformation. The placement is guided by intraoperative angiography. Although the coagulation did not immediately affect the feeding vessel, a postoperative angiogram obtained 1 month later demonstrated elimination of the major abnormalities in the malformation.
