Predictors of Hemodynamic Changes after Carotid Artery Stenting

Abstract

Carotid artery stenting implies instrumentation of the carotid bulb where the baroreceptors are placed and therefore baroceptor's dysfunction may provoke hemodynamic instability, Hemodynamic depression has been reported after carotid artery stenting (CAS) and carotid endarterectomy (CEA). Aim and objectives: This study aimed to assess the predictors of hemodynamic Changes peri carotid artery stenting. Subjects and methods: This was Prospective observational study that was Conducted at Ain shams university hospitals –Railway hospital (ERMED) and Suez insurance hospital, the study was conducted on 20 patients that developed carotid artery stenosis. Results: the results revealed that there was no statistically significant difference between presence and absence of hemodynamic changes as regard Lesion length, Dilatation %, and Lesion location. There was high statistically significant difference between Hemodynamic changes as regard Stent diameter, where p= 0.005. Conclusion: Hemodynamic instability due to hypotension and bradycardia in response to carotid artery stenting occurs in a relatively high proportion of patients. This study reemphasizes the importance of close hemodynamic monitoring during and after CAS and is consistent with the previous studies witch showed that the instability didn't translate into major neurologic complications.
