ABSTRACT
Interventional radiological techniques have assisted the orbital surgeon in the management of some orbital vascular lesions and a variety of other lesions with a significant blood supply. It has also expanded the spectrum of vascular lesions that can be managed by either the radiologist alone or in combination with orbital and other surgeons. This presentation will summarize the techniques currently available and touch on future possibilities. It will not describe methods such as computed tomography or ultrasound guided biopsy, or the potential for stereotactic techniques, which are now used
widely in neurosurgery and probably have a place in the management of a small proportion of lesions affecting the orbit. Specifically, the following disorders will be discussed: carotid-cavernous sinus fistulas, arteriovenous malformations, distensible venous anomalies, preoperative embolization of tumors, and aneurysms.
