Abstract

Use of stent assisted coiling of intracranial aneurysms has shown a recent increase. Despite technical improvement and accumulated clinical experiences, due to insufficient study data, debate over short and long term durability and associated complication has continued. To the best of our knowledge, this case report, for the first time, demonstrates delayed self-expansion phenomenon occurring as an acute and unpredictable complication of Neuroform stent assisted coiling for treatment of a ruptured intracranial aneurysm.

  Fig. 1 Working view of the three dimensional (3D) left internal carotid artery (ICA) shows the aneurysm at the left dominant anterior communicating artery before stent-assisted coiling (A). Working view of the left ICA angiogram shows optimal stent deployment and coil delivery but overlap of distal stent markers (B). Working view of the left ICA angiogram shows intact distal flow despite overlap of distal stent markers (C). Working view of left ICA angiogram shows more coil packing on the aneurysm but not yet none expansion of the distal stent marker(D). Immediately posttreatment, working view of the unsubtracted left ICA shows no flow compromise of parent and expansion of the distal stent marker(E).
