Thrombosis and Recanalization of Small Saccular Cerebral Aneurysm : Two Case Reports and a Suggestion for Possible Mechanism

ABSTRACT

Reports of thrombosis and recanalization of cerebral aneurysm are rare. We report two cases of small, saccular aneurysms in which spontaneous thrombosis had occurred during the preparation for endovascular coiling. Also, we review reported cases and propose the presumed pathogenesis.
