Wrap-clipping as a rescue surgical technique for vessel perforation due to stent strut: a technical note.

BACKGROUND: Arterial injury related to stent strut is rare during stent-assisted coil embolization.

METHOD: The patient underwent stent-assisted coil embolization for a right middle cerebral artery aneurysm. At this time, the parent arterial injury at M1 portion of the middle cerebral artery resulted in subarachnoid hemorrhage. The arterial penetration caused by the stent strut was repaired with wrap-clipping.

RESULTS: Postoperative angiograms demonstrated the complete obliteration of the arterial injury. The patient was discharged without neurological deficits. Neither recurrence nor stenosis was observed after surgery.

CONCLUSIONS: Wrap-clipping is a useful procedure to repair the arterial injury due to the stent strut.
