(compensatory enlargement of the contralateral vertebral is common) 48 yr old male presents w/ retrograde flow in Lt Vertbral A. most likely related to occlusion of the: - Lt Subclavian Artery* -prox lt subclavian occlusion, lt VA flow will reverse to -provide BF to the left arm -condition termed SUBCLAVIAN STEAL*** -occurs more commonly on left side What is the most common anomaly of the Circle of Will is? - Absence of Hypoplasia of 1 or both communicating arteries Which of the following is NOT a branch of the Subclavian Artery? - NOT Brachial Artery - vertebral/thyrocervical trunk/internal mammary artery Differentiation of the Cervical ICA from the EC A can be accomplished by all of the following EXCEPT*: - ICA is usually located anteromedial to the ECA - ECA gives off multiple branches, - ICA normally no branches, bulbous area seen at origin - ICA usually located lateral and posterior to ECA Which o f the following vessels joins the Brachial Veins to form the Axillary Vein*? - Superficial Basilic vein* - begins at Ulnar side of forearm, - crosses ventrally at Antecubital region - lies medial to Brachial in upper arm Which vein in the Antecubital Fossa connects the Cephalic and Basilic (superficial) veins? - Median Cubital Vein (not paired) All of the following are Deep Veins of Upper Extremity* EXCEPT: - Cephalic (Superficial: Basilic, median cubital veins not paired ) - DEEP veins are Deep Palmar venous arch, Radial, Ulnar, interosseous veins of forearm, Brachial, Axillary usually paired deep veins* Brachiocephalic VEIN is found: - on both sides of the neck - formed by the junction of the Subclavian and Internal Jugu lar Veins The longest vein in the body is the: - Greater Saphenous Vein (GSV)* Which of the following is NOT true regarding Perforating Veins*? - Direct blood from the Deep system into Superficial system - Perforating veins direct blood flow from Superfi cial system (GSV/LSV) into Deep system - has 1 valve each, more numerous in the calf than thigh, known as Varicose veins when they are tortuous and dilated due to incompetent valves Portal Vein* is formed by the junction of which of the following veins? - - Splenic and SMV*** What vein normally courses b/n the SMA and Abdominal AO? - Left Renal Vein* -rarely, course behind AO/retroaortic or form ring around AO/circumaortic LRV Which statement is NOT true regarding the Soleal Veins? - Do NOT connect the Superficial Venous System - do empty into Posterior Tibial or Peroneal Veins, found Deep in the calf muscle, do not contain valves Boyd's vein* is a Perforating Vein that connects the Gastrocnemius veins to the: - Posterior Tibial Veins* -16 constant perf s - 8 drain PTV known as Boyds/Cockett* - 4 perf drain Peroneal - 4 drain into Soleal and Genicular veins - thigh, 2 constant perf known as Dodd's group/Hunter* Splenic vein drains into which of the following veins? - Portal vein* Hepatic Veins drain into the: - Inferior Vena Cava* Regarding the IVC, all of the statements below are True EXCEPT: - IVC drains into the Left Atrium of Heart is false -True: IVC is formed by confluence of the Common Iliac veins, has no valves below level of its insertion into the heart, courses to the RT of Abd AO?*** Outermost layer of the Arterial wall is the: - Adventitia* - (outer) adventitia, media, intima (innermost layer) Major function of the Vasa Vasorum* is to: - Provide nourishment to the Tun ica ADVENTITIA*** What is the function of the Semilunar Valves (Aortic/Pulmonary) of the veins? - Maintain unidirectional flow w/in the Venous System - designed to direct flow of blood Back TOWARD Heart by closing during Retrograde flow Which of the foll owing veins has the greatest number of valves*? - Greater Saphenous Vein (GSV)* has 10 -12 valves - LSV 6 -12 - Soleal Sinus 0 - Perforator 1 ea - Infrapop/deep 9 -12 ea - Pop/femoral 1 -3 ea
