Vascular Anatomy Flashcards

The femoral vein becomes the external iliac vein at which anatomical landmark?

Answer: Inguinal ligament

The femoral vein passes beneath the inguinal ligament, at which point it becomes the external iliac vein.

Which branch of the aorta supplies oxygenated blood to the right arm?

Answer: Brachiocephalic (innominate) artery

The brachiocephalic (innominate) artery branches from the aortic arch and divides into the right subclavian artery and right common carotid artery.

The axillary vein transitions into the subclavian vein at which border of the first rib?

Answer: Medial border

The axillary vein becomes the subclavian vein at the lateral border of the first rib, or alternatively described at the medial border as it crosses over.

Which structure separates the subclavian artery from the subclavian vein in the infraclavicular region?

Answer: Anterior scalene muscle

The anterior scalene muscle lies between the subclavian artery (posterior) and the subclavian vein (anterior), serving as an important anatomical separator.

In which direction does the left subclavian vein travel to join the left internal jugular vein forming the left brachiocephalic vein?

Answer: Horizontally and medially

The left subclavian vein travels horizontally and medially across the mediastinum to join the left internal jugular vein, forming the longer left brachiocephalic vein.

The popliteal vein is located in which compartment relative to the popliteal artery?

Answer: Posterior and superficial to the artery

In the popliteal fossa, the popliteal vein lies posterior and superficial to the popliteal artery, with the tibial nerve most superficial.

Which vein is most commonly used as a landmark for ultrasound-guided internal jugular vein access because of its proximity?

Answer: Common carotid artery

The common carotid artery is the primary landmark during ultrasound-guided IJ access; the IJ vein lies lateral and superficial to the carotid artery.
