Female patient K., aged 57, was admitted to the clinic with complaints of periodic headache. The former outpatient examination had revealed unruptured aneurysm of the ICA ophthalmic segment. Left-side carotid angiography and rotation angiography demonstrated aneurysm with a wide neck (5.5 mm); a dome/neck ratio was 1:1. Preoperative preparation (PlavixÒ and AspirinÒ in a dose of 75 mg/day and 300 mg/day respectively) was followed by implantation of self-expandable Neuroform2 stent into sub-supraclinoid segments of ICA and embolization of aneurysm with Matrix biodegrading coils. A postoperative period was uneventful. The patient took antiaggregants during a month after operation; it was done in compliance with a preoperative scheme. Control MRI-examination, carried out a month after intervention, showed no signs of blood flow in an aneurysm cavity.

The demonstration goal was to inform about the nearest favorable result of stent-assisted embolization with use of biodegrading coils, performed in Russia for the first time.
