Assessment of balloon occlusion test of internal carotid artery.

dissection of extracranial internal carotid artery due to balloon guiding catheter resulting in asymptomatic internal carotid artery occlusion

dissection of the internal carotid artery (ica) is a rare condition that accounts for a significant proportion of ischemic strokes in young adults. iatrogenic dissection as a complication of neurointerventional procedures is a traumatic dissection which has been reported relatively rare in the literature. in this report, a case of dissection of the ica is reported that was caused by repetitive ...

Internal carotid balloon test occlusion does require quantitative CBF.

Balloon test occlusion of the internal carotid artery with stable xenon/CT cerebral blood flow imaging.

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 flow (CBF) with the internal carotid artery both open and temporarily occluded with a nondetachable balloon on a double lumen Swan-Ganz catheter. Patients were those in whom we planned to sacrifice the internal carotid ...

Temporary balloon test occlusion of the internal carotid artery: experience in 500 cases.

PURPOSE To describe experience with 500 temporary balloon occlusions of the internal carotid artery, with particular emphasis on the techniques and complications. METHODS Temporary occlusion of the internal carotid artery was accomplished endovascularly using various balloon-catheter combinations. These temporary balloon occlusions were combined, when possible, with cerebral blood flow analys...

Perfusion MR neuroimaging in patients undergoing balloon test occlusion of the internal carotid artery.

BACKGROUND AND PURPOSE We sought to investigate whether the combination of conventional, diffusion-weighted, and perfusion-weighted MR imaging increases the diagnostic accuracy of balloon test occlusion of the internal carotid artery. We describe perfusion anomalies and patterns of enhancement seen in areas of altered brain perfusion during MR-monitored temporary balloon occlusion of the intern...
