About 61613: Intracavernous carotid aneurysm trapping
Reports open surgical trapping of an aneurysm of the intracavernous carotid artery, including aneurysm removal, with or without a muscle graft.
A cerebrovascular or skull-base neurosurgeon treats an aneurysm located in the portion of the carotid artery within the cavernous sinus by surgically trapping it and removing the aneurysm. A muscle graft may be used as part of the trapping procedure. This is an operating-room service for a complex intracranial vascular condition, rather than an endovascular catheter procedure or excision of a nonvascular skull-base lesion.
