Giant intracavernous carotid aneurysm treated by combined trapping and extra- intra-cranial bypass.

A case of a giant intracavernous carotid aneurysm, surgically treated by combined procedure of trapping and extra- intra-cranial arterial bypass, is reported. The authors reviewed the literature concerning the risks of immediate, early and late ischaemic complications related to carotid surgical occlusion. In agreement with other authors, the usefulness of extra- intra-cranial anastomosis in preventing cerebral ischaemia, in patients requiring surgical occlusion of main cerebral arteries, is suggested.
