O papel do forame clinocarotídeo na cirurgia de aneurismas da artéria oftálmica

Abstract

Introduction: The anterior clinoid process may present anatomical variations between individuals, even with changes in the same individual (between sides), mainly related to the formation of a bone bridge between it and the middle clinoid process and the clinoid process later. Recognition of the clinocarotid foramen is important in the treatment of aneurysms of the ophthalmic segment of the internal carotid artery, since the need to perform anterior clinoidectomy may result in inadvertent injury to the vascular structures.

Objective: To review the incidence of clinocarotid foramen and interclinoid bone bridge in current literature.

Method: Integrative review collecting existing information on virtual platforms using the descriptors “brain aneurysm, skull base, internal carotid artery, sphenoid bone” with AND or OR search.

Result: Twenty-five articles were found who met the objective, being read and summarized for this review.

Conclusion: The presence of aneurysms in the paraclinoid region/ ophthalmic segment of the internal carotid artery has a higher incidence in both the clinocarotid foramen and the interclinoid bone bridge.
