Hemodynamic instability associated with the invasive treatment of carotid stenosis

Surgery and endovascular procedures on the common and internal carotid arteries are often accompanied by hemodynamic instability in the periprocedural period. Arterial hypertension typically occurs after carotid endarterectomy, while carotid artery stenting is often associated with arterial hypotension and bradycardia. The cause of hemodynamic instability in periprocedural period is dominantly impairement of carotid sinus baroreceptors function, where surgical and endovascular procedures are performed. The activity of baroreceptors may also be influenced by the patient‘s concomitant diseases, periprocedural management, the type of anesthesia, surgical technique or stent, as well as other less known factors. Knowledge of factors causing hemodynamic instability is important for prevention of postprocedural complications.
