Transcavernous Transclinoidal Half-and-Half Approach for Clipping of a Twice Recurrent Stent-Coiled Giant Basilar Tip Aneurysm: A 3D Surgical Video.

The authors present a 3D surgical video of a half and half, trans-cavernous approach for microsurgical clipping of a giant basilar tip aneurysm that recurred twice after endovascular treatment. The case refers to a 60 year-old man who presented with subarachnoid hemorrhage and was treated with coiling and with a good clinical and radiographic outcome. At three months, he was found to have recurrent filling at the neck of the aneurysm, and was treated again endovascularly with stent coiling. Three months after his second treatment, he again was found to have filling of the base of the aneurysm and was referred for microsurgical clipping.
