Aneurysm Rupture After Treatment With Flow Diverting Stent

Recently there has been increased interest in the use of flow diverting devices to treat intracranial aneurysms. The goal is to deviate the blood flow away from the aneurysm and promote its thrombosis and exclusion from the circulation. This therapy is mostly considered for large, geometrically complex, wide necked, unruptured aneurysms that are difficult or impossible to coil or clip. Recent trials using flow diverting stents have shown promising results [1]. However, little is known about the possible complications of these procedures. This paper presents a hemodynamic study of a cerebral aneurysm that was treated with a flow diverting stent and ruptured a few days later.
