encountered aneurysm of ophthalmic artery in cadaver – a case report
نویسندگان
چکیده
Ophthalmic artery is the branch of internal carotid artery as it emerges from the cavernous sinus medial to anterior clinoid process. Thereafter it traverses in optic canal to enter in the orbit, lies inferolaterally to the optic nerve. It continues forward over the optic nerve (80%) and below the nerve (20%). Main trunk of the artery ends by dividing in to supratrochlear and dorsal nasal branch [1]. Intracranial and intracanalicular part of ophthalmic artery is more prone for the diseases and injuries. Therefore it becomes necessary to have knowledge about its anatomy, relations with the surrounding structures, variations and pathology [2]. One of the pathological conditions is carotid-ophthalmic aneurysm. Finding of aneurysm at the commencement of ophthalmic artery is rare. Location of this type of aneurysm may hinder the diagnostic as well as surgical procedures because of its close proximity with cavernous sinus, carotid siphon and optic nerve. Angiography is the diagnostic tool for carotid-ophthalmic aneurysm [3]. An insight into such particular type of aneurysm might prove fruitful towards neurosurgeries with minimal incidence of injury to surrounding structures. Case Report

Variations in the arterial pattern of the upper limb are abundant and diverse and have been observed frequently either in cadaver dissection or in clinical practice and reports. In the most of these reports, radial or ulnar arteries were commonly involved, which can be damaged during surgical procedures. This report presents a case of a rare variation in arising branches of brachial artery. Dur...
