Abstract
Stroke is a leading cause of death and disability and it is considered the most common and disabling neurological disorder among the elderly worldwide. In particular, atherosclerotic disease at the bifurcation of the common carotid artery is associated with 20 % to 30 % of strokes and it therefore constitutes a huge medical, social and economic problem.
Carotid artery stenosis has different presentations ranging from being asymptomatic, transient ischemic attacks up to completed stroke.
Carotid duplex ultrasound is the established method for diagnosing a cervical carotid artery stenosis, and for post-intervention follow up of patency rates, it may be the single preoperative diagnostic test.
Management of carotid stenosis includes controlling of risk factors, and antiplatelets and anticoagulants, and revascularization either by endarterectomy or angioplasty and stenting.
The results of the randomized trials comparing CEA with CAS demonstrate that CAS is associated with an increased risk of any stroke or death within 30 days. However, significant heterogeneity was found for this outcome measure, which, among other factors, is likely attributable to the evolving nature of CAS (for instance use of protection device and learning curve), as well as to differences in patient characteristics included in these studies and different outcome measures. So, CAS is a continually refined procedure that has much broader application potential than CEA does, and the improving outcomes of CAS procedure in the randomized trials reflects the advancement in technology and the more experience gained by the operators.
The aim of the study was to present the immediate and delayed outcomes of carotid endarterectomy and carotid stenting procedures that were performed on some cases at kasr Alainy hospital. Six patients were included in the study and were sustaining events of cerebral ischemia confined to the ipsilateral internal carotid artery, with stenosis more than 70% ( one case was ≥ 65 %) of arterial lumen, Patients were included whether they were symptomatic or not . Either endarterectomy or angioplasty and stenting were done for each patient randomly and patients were followed up both radiologically and clinically for 12 months. The results showed that carotid stenting is equivalent to carotid endarterectomy in reducing carotid stenosis without increased risk for major complications of death/stroke or restenosis. This confirms that for patients who are candidates for carotid intervention, CEA and CAS should be considered as complementary procedures; in situations in which one procedure is high risk, the other one is feasible with acceptable risk, and CAS provides for those who are trained in both techniques a wide range of options to deal with a broad spectrum of pathologic conditions that affect the cervical carotid arteries.
