partially thrombosed aneurysms.

a. Stenting after coiling with balloon remodeling technique in 24 aneurysms. The choice of this option was to decrease the risk of thromboembolism complications in some

b. Bail-out stenting in 7 aneurysms. In these cases, the deployment of the stent was not planned in advance. Trapping of an extruded coil or coil mass by means of stent placement could prevent parent vessel closure and obviate the need for coil removal. 3. Stent was delivered alone in one aneurysm (0.4%). A 38-year-old woman with a basilar aneurysm was planned to treat with sequential technique. Because trans-stent aneurysm catheterization was difficult and caused stent movement, coil embolization was postponed to a second session. Fortunately, intraaneurysmal spontaneous thrombosis was noted by angiography 3 months later, and coiling was no more an option for her. Complete occlusion was observed at 1-year follow-up angiography

**Figure 2.** Angiography demonstrated a basilar trunk aneurysm in a 38-year-old woman with SAH (A B). A Neuroform stent (4.5 × 20 mm) was deployed across the aneurysm neck, and coil embolization was postponed to a second session due to difficulty in trans-stent aneurysm catheterization (C). One-

All patients underwent CT scanning within 6 hours after the procedure. During the hospital stays, physicians performed neurological examinations of the patients once each day. After

year follow-up angiography demonstrated complete occlusion (D E).
