Spontaneous Regression of a True Intracanalicular Fusiform

Case Reports

Spontaneous Regression of a True Intracanalicular Fusiform Ophthalmic Artery Aneurysm After Endovascular Treatment of an Associated Dural Arteriovenous Fistula.

Ophthalmic trunk aneurysms associated with other vascular malformations are extremely rare, and little is known regarding its natural history and options of treatment. ⋯ A follow-up angiogram at 6 months showed complete obliteration of the dural arteriovenous fistula and regression of the ophthalmic trunk aneurysm. The literature is reviewed, and potential pathophysiologic mechanisms leading to this association and regression in this subgroup of aneurysms are discussed.

BackgroundOphthalmic trunk aneurysms associated with other vascular malformations are extremely rare, and little is known regarding its natural history and options of treatment.Case DescriptionWe present the interesting case of a 51-year-old man who was admitted with progressive visual loss secondary to a concurrent fusiform ophthalmic trunk aneurysm associated with a dural arteriovenous fistula. He was treated with transarterial embolization of the fistulous point.ConclusionsA follow-up angiogram at 6 months showed complete obliteration of the dural arteriovenous fistula and regression of the ophthalmic trunk aneurysm. The literature is reviewed, and potential pathophysiologic mechanisms leading to this association and regression in this subgroup of aneurysms are discussed.Copyright © 2018 Elsevier Inc.
