CORRELATION BETWEEN CLINICAL, ANGIOGRAPHIC AND TRANSCRANIAL DOPPLER SONOGRAPHIC FINDINGS IN PATIENTS WITH MOYAMOYA DISEASE

Nine patients with Moyamoya disease were followed by the authors betwe en 1982 and 1991. The patients were investigated with transcranial Dop pler sonography (TCD), angiography and clinically. Two patients were t reated conservatively. Bilateral extra-intracranial (EC-IC) anastomosi s was performed in 4 patients; in 2 patients bypass surgery was perfor med unilaterally. One patient with an aneurysm of the carotid artery p resented a subarachnoidal haemorrhage. There was a good correlation be tween TCD and angiographical findings in all patients. In four patient s indication for bypass surgery was established by TCD. All patients w ho underwent EC-IC bypass surgery improved clinically; the symptoms di sappeared in three patients and improved markedly in two patients. Tra nscranial Doppler sonography is proven to be a reliable atraumatic too l in diagnosis, indication for treatment and postoperative follow-up i n patients with moyamoya disease.
