title: [Operative management of trigono-atrial lesions].
abstract: Trigono-atrial-Lesions are microsurgically serios accessible, the results of transcortical aproaches are difficult and frequently unsatisfactory. The microsurgical anatomy of the trigono-atrial region will be studied on 100 brain hemispheres (the posterior cerebral arteries were injected selective on 70 hemispheres). According to the anatomical findings, an interhemispheric microsurgical approach has been developed. The operative results of 25 patients with different atrial lesions are presented. There was no operative mortality, the postoperative morbidity was 12%, in 24% (n = 6) the preoperative state was still unchanged, in 12 cases (48%) we note a normal neurological and neuropsychological postoperative status. In 4 patients (16%) the neurological symptoms are postoperatively improved. According to these first results, the described transatrial approach seems to be a real alternative for careful selected meanly leftsided lesions of the trigone.
