Spontaneous and complete regression of cerebral arteriovenous malformations has rarely been reported in the literature. We describe two new cases with a literature review.

The Leo stent is a cranial self-expanding stent recently developed for the treatment of wide-neck aneurysms. We report the first case with total occlusion of a cavernous aneurysm nine months after stent placement without complementary coiling.

The ultimate goal of endovascular treatment of intracranial aneurysms is complete occlusion of the aneurysm without compromising the parent artery. Several techniques have been described for the treatment of wide-necked aneurysms. An innovative method is proposed for the treatment of wide-necked aneurysms with the neck incorporated in the parent artery.
