Abstract:

Aim. Was to demonstrate our experience of using the stent-assistant technology for treatment of thromboembolic complication during endovascular procedures in extra- and intracranial arteries.

Materials and methods. Five patients with thromboembolic complication were successfully treated using stent-assistant technology In one case thromboembolic complication appeared during stenting of ICA, another - during performing of diagnostic cerebral angiography In 3 cases thromboembolic complications appeared during endovascular occlusion of intracranial artery. In four cases we used stent Solitaire (Covidien) in one case - Enterprise (Codman).

Results. In all cases we achieved full restoration of blood flow in intracranial vessels. Three patients were discharged without any neurological deficit. Two patients were discharged with minimal neurological deficit (mRS 1).

Conclusion. Stent-assistant technology can be successfully used in treatment of thromboembolic complications during endovascular procedures in extra- and intracranial arteries.
