Arterial dissection is now recognized as an important cause of stroke. Most reported dissections involve the extracranial portion of the internal carotid artery (ICA) and vertebral arteries. Spontaneous dissecting aneurysms of the intracranial ICA are uncommon. Endovascular treatment for cerebral aneurysms has become widespread; however, the dissecting aneurysm is still difficult to treat if the parent artery has to be preserved. More recently, stenting has been advocated for use with endosaccular coiling, with the coils held in place by the stent. We herein report a spontaneous intracranial ICA dissecting aneurysm in a 51-year-old woman who was treated using a new technique of combined stent and coils.
