Abstract
The affect of bilateral cervical ganglionectomy was observed in basilar artery vasospasm induced by the application of Oxyhemoglobin in cats. In cases with vasospasm continued for,1 or 2 hours, basilar artery was dilatated and rCBF at white matter of pons was increased after the ganglionectomy. On the other hand, These changes after the ganglionectomy were slight in cases with vasospasm continued for 3 or 5 hours.
Clinically, the effectiveness of cervical ganglionectomy performed in early stage of vasospasm was reoprted. The findings in this report suggest it's significance.
