Carotid interventions and blood pressure

Arterial baroreceptors are pressure sensors found in the carotid sinus near the bifurcation of the carotid artery and in the aortic arch. Carotid interventions, whether endovascular or surgical, affect this complicated control system and the post-interventional blood pressure behavior. Comparisons between the intervention techniques, however, are challenging due to the varying measurement methods, duration of observation, and patient populations. The question as to which interventional method is preferable, if undisturbed regulation of blood pressure is concerned, still remains unanswered. The fact that blood pressure events (i.e., hemodynamic instability, hypertension, unstable blood pressure) frequently occur both immediately after intervention and in the long term, mandates a particularly careful cardiopulmonary and blood pressure monitoring. Direct and indirect measurements of baroreceptor sensitivity can be helpful in identifying high-risk patients, although the association to hard clinical endpoints is rarely documented for methodological reasons.
