Peri-procedural variables and outcomes of long-period hemodynamic instability after carotid artery angioplasty and stenting.

CAS-induced HI occurs in a considerable percentage while several peri-procedural variables are determined as independent predictors to develop long-period HI. Patients with prolonged HI are associated with increased risk of neurologic events and thus standardized intervention as well as management of long-period HI are of critical importance during clinical process.
