Fig. 1. Intraoperative dopplerography in carotid endarterectomy.

A) Registration of initial flow indices on the “open” carotid artery with the 8MHz CW probe. B) Patterns of “hampered perfusion” in CCA and “stenosis” (systolic BFV of 288 cm/s) in ICA. C) Registration of flow indices after endarterectomy and plasty of the opening of ICA with a patch made of PTFE. D) Major flow in the opening of ICA (systolic BFV of 55 cm/s).
