Methods Test balloon occlusion of the internal carotid artery was performed in 44 patients
with a variety of head and neck tumors or aneurysms. Technetium-99m-HMPAO was …

We describe a technique to predict preoperatively the safety of permanently occluding an
internal carotid artery. The method was performed by imaging stable xenon cerebral blood …

PURPOSE To describe the technique of using SPECT brain blood flow imaging to identify
patients at risk for having strokes after balloon or surgical ligation of an internal carotid …

carotid artery balloon test occlusion (BTO) and single-photon emission computed …

PURPOSE To describe experience with 500 temporary balloon occlusions of the internal
carotid artery, with particular emphasis on the techniques and complications. METHODS …

Balloon test occlusion (BTO) of the internal carotid artery (ICA) is used in conjunction with
single-photon emission computed tomography (SPECT) imaging to assess the …

A new method that employs a cerebral perfusion imaging agent, 99mTc-HMPAO, is
described for identifying those patients who clinically pass an internal carotid artery balloon …

MATERiALS AND METhODS Patient Population Twentypatients, 7 men and 13women, with

Permanent occlusion of the internal carotid artery may be required for en bloc resection of a
neck tumor or to treat certain aneurysms. The risk of ischemic infarct is usually assessed with …

A balloon test occlusion of the internal carotid artery was performed in 11 patients with
