The Haemodynamic Effect of Carotid Endarterectomy

Objectives: to assess the haemodynamic effect of carotid artery surgery, and to relate postoperative changes to the state of cerebral circulation before revascularisation. Materials and methods: using transcranial Doppler we studied bilateral middle cerebral artery (MCA) flow velocities before and o...

Zusammenfassung:	Objectives: to assess the haemodynamic effect of carotid artery surgery, and to relate postoperative changes to the state of cerebral circulation before revascularisation. Materials and methods: using transcranial Doppler we studied bilateral middle cerebral artery (MCA) flow velocities before and on 1st day, 2nd or 3rd day and 4th or 5th day and 3 months after carotid surgery in 61 patients. In addition, ipsilateral MCA flow velocity was monitored continuously during surgery. Data were related to the internal carotid artery (ICA) perfusion pressure (cerebral perfusion pressure index, CPPI), measured directly before ICA clamping. Results: postoperatively, MCA flow velocities increased significantly overall (p
