Temporary balloon occlusion test of the left vertebral artery using parenchymography as tolerance predictor. A case report.

Temporary balloon occlusion is used as tolerance predictor in patients undergoing vascular occlusion with the aid of clinical assessment during a 30-40 minute temporary occlusion. Several other techniques have been used to help predict each patient's tolerance. Digital cerebral parenchymography (DCP) was originally described to improve our analysis of brain perfusion during ischemic events. We report a case using DCP as tolerance predictor in a patient undergoing sacrifice of the left vertebral artery.
