The supraorbital artery is a branch of the ophthalmic artery. It passes anteriorly within the orbit to exit the orbit through the supraorbital foramen or notch alongside the supraorbital nerve , splitting into two terminal branches which go on to form anastomoses with arteries of the head.
The superior ophthalmic vein is the only orbital vein whose course generally parallels the course of an orbital artery: it has a similar course as the ophthalmic artery [1] (however, the latter instead exits the orbit through the optic canal). [2] Within the orbit, the superior ophthalmic vein passes posterior-ward alongside the ophthalmic artery.
Magnetic resonance angiography (MRA) is a group of techniques based on magnetic resonance imaging (MRI) to image blood vessels. Magnetic resonance angiography is used to generate images of arteries (and less commonly veins) in order to evaluate them for stenosis (abnormal narrowing), occlusions, aneurysms (vessel wall dilatations, at risk of rupture) or other abnormalities.
The ophthalmic artery (OA) is an artery of the head. It is the first branch of the internal carotid artery distal to the carotid sinus . Branches of the ophthalmic artery supply all the structures in the orbit around the eye , as well as some structures in the nose , face , and meninges .
Superior orbital fissure syndrome, also known as Rochon-Duvigneaud's syndrome, [4] [5] is a neurological disorder that results if the superior orbital fissure is fractured. ...
With the introduction of the Seldinger technique in 1953, the procedure became markedly safer as no sharp introductory devices needed to remain inside the vascular lumen. Radial access technique for angiography can be traced back to 1989, when Lucien Campeau first cannulated the radial artery to perform a coronary angiogram.
The supraorbital vein is a vein of the forehead. It communicates with the frontal branch of the superficial temporal vein. It passes through the supraorbital notch, and merges with the angular vein to form the superior ophthalmic vein. The supraorbital vein helps to drain blood from the forehead, eyebrow, and upper eyelid.
Interventional radiology (IR) is a medical specialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound. IR performs both diagnostic and therapeutic procedures through very small incisions or body orifices.
