The anatomy of the orbital vascular bed is complex, with tremendous individual variation. The main arterial supply to the orbit is from the ophthalmic artery, a branch of the internal carotid artery. The external carotid artery normally contributes only to a small extent. However, there are a number of orbital branches of the ophthalmic artery that anastomose with adjacent branches from the external carotid artery, creating important anastomotic communications between the internal and external carotid arterial systems. The venous drainage of the orbit occurs mainly via two ophthalmic veins (superior and inferior) that extend to the cavernous sinus, but there are also connections with the pterygoid plexus of veins, as well as some more anteriorly through the angular vein and the infraorbital vein to the facial vein. A working knowledge of the orbital vasculature and lymphatic systems is important during orbital, extraocular, or ocular surgery. Knowing the anatomy of the blood supply helps one avoid injury to the arteries and veins during operative procedures within the orbit or the eyelid. Inadvertent injury to the vasculature not only distorts the anatomy and disrupts a landmark but also prolongs the surgery and might compromise blood flow to an important orbital or ocular structure. Upon entering the cranium, the internal carotid artery passes through the petrous portion of the temporal bone in the carotid canal and enters the cavernous sinus and middle cranial fossa through the superior part of the forame lacerum . It proceeds forward in the cavernous sinus with the abducens nerve along its side. There it is surrounded by sympathetic nerve fibers (the carotid plexus ) derived from the superior cervical ganglion. It then makes an upward S-shaped turn to form the carotid siphon , passing just medial to the oculomotor, trochlear, and ophthalmic nerves (V1). After turning superiorly in the anterior cavernous sinus, the carotid artery perforates the dura at the medial aspect of the anterior clinoid process and turns posteriorly, inferior to the optic nerve.

This study describes a case of traumatic carotid-cavernous fistula poorly treated with balloons and rescued by coils through a PComA approach. A six-year-old boy suffered a left temporal bone puncture wound. Digital subtraction angiography disclosed a left carotid cavernous fistula. Five balloons were implanted into the cavernous sinus and the parent artery was sacrificed unwillingly, but the residual fistula retro-engorged by the ophthalmic artery communicated with the maxillary artery and the post circle through the PComA. We finally occluded the residual fistula through the PComA with coils. Once the parent artery was sacrificed and the distal residual fistula still retro-engorged, another patent communicating artery may be a rescue approach.

✓ Some intracranial aneurysms that might be considered inoperable by open craniotomy are readily treatable by stereotaxic thrombosis. This is possible because the stereotaxic technique requires only that some point on the fundus of the aneurysm can be punctured with a needle. Illustrative cases are given describing the successful treatment of aneurysms arising at the origin of the ophthalmic artery, within the cavernous sinus, within the sella turcica, and from the vertebrobasilar and the posterior inferior cerebellar arteries ventral to the brain stem. The aneurysms within the sella or cavernous sinus can be approached through the sphenoid sinus, and the aneurysms ventral to the brain stem can be approached through the clivus without opening the dura.
