RVT REGISTRY REVIEW QUESTION WITH CORRECT SOLUTIONS 2023Aortic Arch Branches brachiocephalic (innominate), left common carotid, left subclavian Bovine Arch common origin of the left CCA and innominate Subclavian Artery runs on the outer border of the 1st rib and posterior to the clavicle Major Branches of the Subclavian Artery vertebral, thyrocervical, dorsal scapular, internal thoracic, costocervical, internal mammary Axillary Artery originating at the lateral border of the 1st rib and terminating at the lower border of the teres major muscle Major Branches of the Axillary Artery superior thoracic, lateral thoracic, anterior circumflex humeral artery, thoraco-acromial, sub-scapular, posterior circumflex Brachial Artery originates at the head of the humerus and terminates at the antecubital region; lies medial to the humerus but courses anteriorly toward the antecubital fossa Radial Artery originates at the antecubital fossa and terminates at the deep palmar arch; courses on the lateral side of the forearm Which is the smaller of the two forearm arteries? radial artery Ulnar Artery originates at the antecubital fossa and terminates at the superficial palmar arch; courses on the medial side of the forearm Palmar Arch (Volar) consists of the deep and superficial palmar arch which are located within the hand Digital Arteries originate from the palmar arch and have 2 branches that are lateral and medial Right Common Carotid Artery originates from the innominate Left Common Carotid Artery originates from the aortic arch External Carotid Artery supplies blood to the face and scalp and is an important collateral pathway 8 ECA Branches superior thyroid, ascending pharyngeal, lingual, facial, occipital, posterior auricular, internal maxillary, superficial temporal Superficial Temporal major artery of the face and is a common collateral, also used for the "temporal tap" Internal Carotid Artery supplies most of the anterior circulation to the brain, eyes, forehead, and nose; no cervical branches 1st ICA Branch ophthalmic artery (intracranial) Vertebral Artery originates from the subclavian artery and terminates at the confluence to form the basilar; supplies the posterior circulation to the brain Anterior Cerebral Artery originates at the terminal ICA and courses anterior in the brain to provide anterior circulation Middle Cerebral Artery originates at the terminal ICA and courses lateral toward the temporal bone and provides anterior circulation Posterior Cerebral Artery originates at the basilar artery and wraps around the cerebellum; provides posterior circulation to the brain Atherosclerosis affects the intimal and medial layers of the arterial wall; common sites are origins and bifurcations What is the most common cause of arterial disease? atherosclerosis Dissection medial layer is weakened causing a "false lumen" into the media of the artery Thromboembolic plaque that breaks off and travels distally and lodges into a smaller vessel
