Eversion Carotid Endarterectomy…
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.
