[Carotid endarterectomy and endovascular angioplasty with stenting in patients with atherosclerotic stenoses and occlusions of the internal carotid artery].

The authors made a comparative assessment of carotid endarterectomy and endovascular angioplasty with stenting in patients with atherosclerotic lesions of the carotid arteries. The authors consider that indications to stenting and carotid endarterectomy are identical in patients with stenose and occlusions of the carotid arteries. Contraindications to angioplasty of carotid arteries are determined.

[Role of extra-intracarotid anastomosis in the surgical treatment of chronic cerebral ischemia].

About 500 patients with ischemic brain lesions were studied. Out of them 201 patients underwent 230 operations: 140 extra-intracarotid bypass (EIB) and 90 various interventions on brachiocephalic branches. The study of cerebral hemodynamics by examining blood pressure in the central artery of the retina and middle cerebral artery during surgery, comparison of these findings with those of Doppler sonography and angiography made the authors conclude that EIB improves cerebral hemodynamics, and in some cases it is the only intervention able to improve the status of patients.
