Vascluar 1 - UE Venous

Digital veins

drain blood from the fingers

Superficial palmar venous arch

collects superficial drainage and continues into the ulnar veins

Deep palmar arch

drains deeper structures and continues into the radial veins

Radial and ulnar veins

continue proximally through the forearm

Brachial vein

join near the axilla to form the axillary vein

Axillary vein

becomes the subclavian vein at the upper border of the first rib

Subclavian

joins the internal jugular vein at the clavicular level

Axillary

Subclavian and internal jugular veins join

to form the

SVC

Right and left brachiocephalic veins join to

form the

Right atrium

The SVC enters the

Superficial veins

run above the deep fascia

Cephalic

travels laterally and is the longest vein in the arm

Median cubital vein

connects the cephalic and basilic veins at the antecubital fossa

Deltoid

Cephalic vein courses along the biceps and

Dorsal

Cephalic originates from the ____ venous arch of the hand

ulnar component

Basilic vein arises from the ____ of the dorsal venous arch

Median antebrachial

arises from a palmar venous plexus

External jugular

receives blood from the cranium, face, and neck

Internal jugular vein

drains the face and neck

Neck veins

provide collateral pathways when central veins are obstructed

Congestive heart failure

An enlarged IJV may be seen with

First rib

The subclavian vein continues the axillary pathway after the

Clavicle

IJV and subclavian vein meet near the

Internal thoracic

may be seen near the IVJ and Subcl confluence

Vertebral

drains the head and terminates in the posterior aspect of the brachiocephalic vein

Internal thoracic and inferior thyroid

may drain into the brachiocephalic veins

LE

Does UE or LE have more valves?

Rouleax flow

may be visible near the valve sinus

Venous confluences

Most common thrombus sites

Distal arm veins

may normally lack spontaneous or phasic flow, but will augment with distal compression

Acute thrombus

• Anechoic or lightly echogenic filling defect

• Dilated, non-compressible vein

• Spongy texture, poorly attached to the wall

Chronic thrombus

• Echogenic, contracted vein with wall thickening

• Partial color flow from recanalization or collaterals

• May have valve damage or fibrotic webbing

Effort thrombus

caused by repetitive arm motion or thoracic outlet compression

SVC syndrome

obstruction of central venous outflow → bilateral arm and facial swelling

Prox obstruction

Loss of respiratory phasicity suggests

Obstruction distally

No augmentation suggests

Prox obstruction or extrinsic compression

Continuous flow suggests

Anticoagulation

primary therapy for acute DVT

Surgical decompression

Surgical treatment for thoracic outlet syndrome
