Regional Cerebral Blood Flow Measurement as a Supportive Indication for Vascular Surgical Procedures

The indication for surgical procedures to improve the cerebral perfusion is usually given by the clinical findings and course as well as by the results of the angiographic examination. This is true for extraintracranial arterial bypass operations as well as for vascular surgical treatments at the internal carotid. In those cases lowered perfusion values in the regional cerebral blood flow (rCBF) measurement will be found (1), corresponding with the clinical and the angiographic findings. A change in the indication given by the clinical and angiographic findings as a result of the rCBF measurement is unusual. The clinical findings and course, the angiographic results, and the values of the rCBF measurement fit together, each supporting the indication.
