Retrieval of a dislocated coil and stent-assisted coiling by Solitaire® stent during endovascutar treatment of an intracraniat aneurysm

coilingCoil embolization is an effective and safe procedure for the treatment of intracranialaneurysms. It is known to produce good clinical outcomes and provide sufficient protec-tion against recurrent bleeding [1-4]. In a systematic review, Brilstra et al. retrieved19 (1.4%) re-bleeding episodes, 36 (2.6%) aneurysmal ruptures, 124 (9%) ischemic and 55(4%) permanent complications in 1383 patients with ruptured and unruptured aneurysmstreated with coil embolization. Complications occurring during coil embolization includerupture of aneurysm, arterial dissection, bleeding and microembolic complications. Coildislocation is another rare complication of coil embolization which occurs in 2-6% of theprocedures [3,5-7]. Thromboembolic complications during endovascular treatment couldbe caused by coil dislocation or thrombus formation in parent vessel because of vasospasm[2]. Dislocation can be fixed by retrieval of the coil from the aneurysm or placement of thecoil back in the aneurysm [3,8]. Retrieval of a dislocated coil can be achieved by snaresand stent retrievers.We present herein a case where Solitairestent (Ev3, Irvine, CA, USA) was used forretrieval of a dislocated coil, which protruded into the proximal part of the internal carotidartery (ICA) during endovascular treatment and secondly for total aneurysm treatment bystent-assisted coiling technique in the same patient.2015 Editions francaises de radiologie.
