Question | Answer |
---|---|
The greater saphenous vein: | passes upward on the anteromedial calf and the posteromedial to medial thigh. It ends by passing through the saphenous hiatus in the deep fascia of the proximal thigh to enter the common femoral vein. |
Which of the folloing is NOT correct regarding the GSV? A. It passes on the sup/lat side. B. It passes on the sup/med side. C. It enters the FV. D. Originates along the dorsum of the foot. E. It has more valves in the calf than in the thigh. | A. It passes superiorly on the lateral side of the knee. |
The superficial vein that sends flow to the three main perforating veins of the distal calf is called: | Posterior arch vein The posterior arch vein, since it connects the Cockett perforators in the calf, is implicated in the formation of venous stasis ulcers. |
Boyd's perforating vein is located: | Near the knee. There are many, many perforating veins. The main ones are the Cockett perforators in the mid to distal calf (connected by the posterior arch vein), Boyd's perforator near the medial knee. |
Where are the Crockett perforators located? | In the mid to distal calf. Color-flow perforator assessment are becoming fairly common for patients with chronic venous insufficiency. |
Where are Boyd's perforators located? | Near the medial knee. Color-flow perforator assessment are becoming fairly common for patients with chronic venous insufficiency. |
Where are Dodd's perforators located? | Somewhat above the knee. Color-flow perforator assessment are becoming fairly common for patients with chronic venous insufficiency. |
Where are Hunter's perforators located? | Around mid thigh. Color-flow perforator assessment are becoming fairly common for patients with chronic venous insufficiency. |
The left common iliac vein: | Crosses posterior to the right common iliac artery just distal to the aortic bifurcation. The LT CIV is medial to the artery. The IVC is to the RT of the AO. Thus the LT vein must cross some arterial structure to communicate with the IVC. |
The brachial veins connect the: | Ulnar and radial veins to the axillary vein. |
Of the deep veins, which is imaged LEAST commonly? | Distal profunda veins. (Distal deep femoral vein.) Because of its depth, these veins are usually very difficult to image. |
The term muscle pump refers to: | The calf muscles. Refers to the mechanism of venous return from the lower extremities, which overcomes hydrostatic pressure in the upright patient. The veins and sinuses fill during relaxation; then contraction of muscles propels blood cephalad. |
Which vein in the antecubital fossa connects the cephalic and basilica veins? | Median cubital vein |
Which of the following is NOT a deep vein of the upper extremity? A. Ulnar vein B. Cephalic vein C. Axillary Vein D. Radial vein E. Brachial vein | Cephalic Vein |
The brachiocephalic vein is found: | On both sides of the neck. The venous anatomy of the neck varies from arterial in that this vein occurs bilaterally, and the artery is found only on the right. This vein is formed by the junction of the subclavian and internal jugular veins.+ |
Which of the vessels joins the brachial veins to form the axillary vein? | Basilic vein It begins on the ulnar side of the forearm and crosses ventrally at the antecubital region. The basilic vein lies medial to the brachial artery in the upper arm. |
Muscular veins of the calf that empty into the popliteal vein behind the knee are: | Gastrocnemius veins Commonly seen on the venous duplex scan and may be thrombosed like other calf veins. They should be distinguished from soleal sinuses, which empty into the posterior tibial and peroneal veins in the calf itself. |
Compared to the arteries, veins have: | Thinner adventitia and media Intimal linings are the same size in arteries and veins--a layer of endothelial cells. |
Regarding venous valves, which is FALSE: A. Essential to muscle pump B. Bicuspid C. Endothelial tissue D. Allow flow only away from the heart. E. Have sinuses to facilitate closure | D. This statement about venous valves--"Allow flow only away from the heart"-- is false. Valves (when they are working properly) allow flow only toward the heart. |
