Eversion Carotid Endarterectomy is Associated with Decreased Baroreceptor Sensitivity Compared to the Conventional Technique

This study published in the European vascular and endovascular Surgery Journal determined differences in postoperative barorecepter sensitivity (BRS) following eversion CEA (E-CEA) and conventional CEA (C-CEA). Sixty-four patients undergoing E-CEA (n = 37) and C-CEA (n = 27) were prospectively studied. Non-invasive measurements of mean arterial pressure (MAP), cardiac output (CO) and total peripheral resistance (TPR) were taken perioperatively over three 10-min periods. Baroreflex gain was calculated as the sequential cross-correlation between heart rate and beat-to-beat systolic blood pressure. Compared with changes observed after C-CEA, E-CEA was associated with an increase in systolic pressure, diastolic pressure, mean arterial pressure and heart rate on postoperative day 1. BRS decreased after E-CEA significantly onday 1 and 3. By contrast, BRS increased after C-CEA on day 1 and day 3. These findings are likely the result of carotid sinus nerve interruption during E-CEA and preservation with C-CEA.
