The aim is to compare the safety of using transfemoral and transradial approach in patient undergoing carotid arteries stenting.
The use of transradial approach in carotid arteries stenting can significantly decrease the amount of adverse events associated with transfemoral approach such as bleeding or hematoma. Otherwise providing transradial approach is fraught with technical difficulties of common carotid artery canulation that can result in embolic complications. Taking into account the absence of studies in this area of medicine, providing investigation evaluating parameters of safety for both methodics is very actual.

| Transradial carotid artery stenting | Procedure | The radial artery is punctured with a trocar. A guidewire is advanced through its lumen, and the trocar is withdrawn. An introducer is passed into the vessel. Then a standard endovascular procedure is carried out under local anesthesia and fluoroscopic control. To prevent cerebral embolism, a protection device is positioned distally of target lesion in internal carotid artery. Then balloon angioplasty of target lesion (if required) is provided. After the angiographic control stent is implanted. After removing all of devices a control angiographic study is provided. Medical therapy includes aspirin(acid acetylsalicylic) 125 - 300 mg/d and plavix (clopidogrel) in dose 300-600 mg prescription before the procedure and heparin sodium injection during the procedure(5000 U iv). After the procedure aspirin(acid acetylsalicylic) in dose 100 mg/d within long period should be prescribed in all the patients, and Plavix (clopidogrel) in dose 75/d should be prescribed within 2 months. |
