Microsurgical treatment of juxtapeduncular angiomas.

Five patients harboring juxtapeduncular angiomas were all treated by a direct microsurgical approach. Anatomic considerations, angiographic data on the feeding arteries, and related anomalies are discussed. The operating microscope and deep hypotension were very useful for the complete removal of these lesions, which were approached in most cases by a "backward" technique. Diffuse bleeding from the paraventricular area was difficult to handle. There were no postoperative deaths. At follow-up examination, 1 patient had hemiparesis and hemianopia, 2 patients had mild visual field defects, and 2 patients had normal neurological examinations. All but one of the patients have resumed their previous occupations. It is concluded that microsurgery constitutes the best treatment for these malformations.
