Delayed parent artery narrowing occurring months after aneurysm surgery: a complication after aneurysm surgery--technical case report.

The authors report two patients with a rare complication of parent artery narrowing that occurred 3 and 6 months after aneurysm surgery. In both cases, the stenosed arteries had been wrapped around their entire circumferences with neurosurgical sponge (cotton linter) and coated with plastic adhesive (cyanoacrylate compounds) and the aneurysmal neck had been clipped. This reinforcement procedure was considered to have caused the unusual delayed arterial narrowing. The importance of avoiding circumferential parent artery wrapping with plastic-adhesive coating is emphasized.
