Several approaches to the treatment of intracranial dissecting aneurysms have been used. We report our experience with endovascular treatment of intracranial dissecting aneurysms since Enterprise VRD (Johnson & Johnson Codman, Miami, FL, USA) stent was introduced into Japan. Between July 2010 and December 2012, 18 patients (eight ruptured and 10 unruptured) underwent endovascular treatment of intracranial dissecting aneurysms. Patients with a ruptured dissecting aneurysm were treated as follows: Four patients were treated with internal trapping using coils, three patients with blood blister-like aneurysms (BBAs) were treated with placement of three or four stents, and one by stent-assisted coil embolization. All patients with an unruptured dissecting aneurysm except one treated with internal trapping were treated by stent-assisted coil embolization. All aneurysms were completely occluded. Procedural complications occurred in one BBA with parent artery occlusion and cerebral infarction. Of all the other patients treated with stents, all parent arteries were preserved.
Treatment using stents is an effective alternative for the treatment of intracranial dissecting aneurysms. However, in cases of ruptured dissecting aneurysm, strict indications for the use of stents may be needed.
