[The mechanisms of speech recovery following revascularization surgery in patients having had an ischemic stroke].
A study is presented of 20 patients with ischemic stroke showing speech disorders. After the surgically performed extra-intracranial microanastomosis of the superficial temporal artery with branches of the middle cerebral artery there always followed an improvement of the aphasic defect. During control angiographic examination a 2% solution of novocaine was introduced into the carotid artery. Injection of the preparation into the left carotid artery produced a short-term cessation of speech while administration of novocaine into the right carotid artery did not effect the speech function. It is concluded that speech restoration occurs due to rehabilitation processes in the dominant hemisphere of the brain.
