Early fatal hemorrhage after endovascular cerebral aneurysm treatment with a flow diverter (SILK-Stent): do we need to rethink our concepts?

Neuroradiology. 2011 Jan;53(1):37-41. doi: 10.1007/s00234-010-0676-7. Epub 2010 Mar 26.


A 69-year-old woman presenting with short lasting recent episodes of visual impairment was treated uneventfully with a flow diverter covering the neck of a large paraophthalmic aneurysm. As angiography showed immediate flow reduction we abstained from additional coiling which was initially planned. Eleven days later CT demonstrated nearly complete thrombosis of the aneurysm. Twenty days after treatment the patient suffered a lethal subarachnoid hemorrhage after rupture of the aneurysm. All available data were reviewed and beside hemodynamic factors instability of the intra-aneurysmal thrombus is discussed as a possible cofactor leading to this disastrous event.
