At the meeting of the Western Section of the Triological Society in Laguna Niguel, Calif, James C. Andrews, MD, Los Angeles, Calif, in association with Anton Valvanis, MD, and Ugo Fisch, MD, Zurich, Switzerland, reported on the management of the internal carotid artery in surgery of the skull base, using detachable balloon catheters to produce temporary or permanent occlusion.
Using arteriography and temporary occlusion via balloon catheters, patients who have tumors that may require resection of the internal carotid artery to eliminate disease can be evaluated preoperatively to assess collateral circulation. The balloon catheter allows for preoperative assessment of the patient by occlusion of the internal carotid artery under local anesthesia, with the patient monitored for development of neurologic symptoms and electroencephalographic changes. The balloons are placed at the following three sites: the carotid bifurcation, the skull base, and proximal to the ophthalmic artery. The patient is monitored for
