Surgical treatment of large/giant carotid-ophthalmic and other intradural internal carotid artery aneurysms

Surgical approaches to paraclinoid aneurysms (PCAs) have evolved considerably since the early 1980s, when Dolenc’s work clarified the anatomy of the cavernous sinus and the paraclinoid region. An improved understanding of this anatomy has led to the area no longer being considered prohibited territory for surgeons [1, 2, 6, 7]. The Dolenc method has revolutionized the management of PCAs, dividing thought about their treatment into distinct eras, pre-Dolenc and post-Dolenc [6, 7].
