Diagnosis and endovascular therapy of vascular lesions in the cavernous sinus

Abstract

One hundred and twenty-eight lesions of the cavernous sinus were diagnosed and treated by endovascular embolization alone or combined with postembolization surgery. All patients presented with acute or subacute cavernous sinus syndrome. A complete angiographic evaluation included bilateral internal and external carotid and vertebral angiography. A total of 88 carotid-cavernous (c-c) fistulae (68 traumatic and 20 spontaneous) and 40 giant aneurysms were demonstrated. A complete anatomic cure or satisfactory clinical improvement was seen in 67 of 68 traumatic fistulae, in 14 of 20 spontaneous c-c fistulae and in 38 of 40 giant intracavernous aneurysms. An overall 15 per cent immediate and 2.7 per cent long-term morbidity with one death was observed. The technical and clinical complications involving endovascular therapy of each specific intracavernous vascular lesion are analyzed.
