| Sumario: | Risk of cerebral hypoperfusion during carotid endarterectomy arterial is the main limiting factor of this technique. Shunt allows partial maintenance of cerebral perfusion during clamping. We analyze the hemodynamic behavior of ipsilateral middle cerebral artery and internal carotid artery during surgery. For this purpose, a preoperative intracerebral hemodynamics study using transcranial colour-coded duplex has been performed along with continuous transcranial ultrasound monitoring of intraoperative middle cerebral artery and measurement of invasive pressure in common carotid and internal carotid arteries during carotid endarterectomy. We have observed a significant positive relationship between presence or absence of collateral circulation in the preoperative study by transcranial doppler and maintenance of both carotid pressures and velocities in middle cerebral artery during the intervention. The analysis of collateral circulation patterns allows us to identify patients with the highest risk of presenting intraoperative cerebral ischemia and to require the use of shunt during clamping. |
