Abstract
Since their introduction into clinical practice two decades ago, flow diverting stents became a powerful device in endovascular treatment of different cases of complex intracranial aneurysms, especially large and giant ones. These devices provide higher coverage of the parent vessel (30–50%) compared to conventional intracranial stents, decreasing blood flow into the aneurysm and producing eventual aneurysmal thrombosis. Compared to stent-assisted coiling results in literature, they showed comparable morbidity and mortality [2,3]. However, regarding endovascular treatment of complex intracranial aneurysms arising in very large diameter vessels, (≥5.3 mm - LDV), only few devices are available on the market. We present here a case of embolization of complex large carotid aneurysm using a largest available FD stent on the market, DERIVO2, 8x50 (Acandis GmbH & Co. KG, Pforzheim, Germany).
