[The dynamics of the cerebral circulation during the surgical treatment of paragangliomas of the neck].
Clinical and rheoencephalographic studies ot 17 cases of paraganglioma of the neck revealed insufficient collateral blood circulation after compression of the common carotid artery on the affected side. In such cases, surgery carries a risk of brain ischemia. Improvement of collateral blood circulation was achieved by rheoencephalographically controlled compression of the common carotid artery performed daily with increasing duration. A patient was considered eligible for surgery if no signs of brain hemisphere ischemia were apparent following a 40% or less decrease in rheoencephalographic anacrotism amplitude from baseline. Common or internal carotid arteries were resected in 6 out of 17 cases of neck paraganglioma dissection. Adequate preoperative preparation prevented cerebral ischemia development in the postoperative period.
