Upper extremity vein anatomy
The upper extremity, also known as the arm, contains a complex network of veins that play a crucial role in the circulatory system. These veins function to transport blood from the arms back to the heart and lungs to be oxygenated.
There are two main types of veins in the upper extremity: superficial veins and deep veins. Superficial veins are located close to the surface of the skin and can be easily seen and felt. These veins include the cephalic vein, which runs along the lateral aspect of the arm and wrist, and the basilic vein, which runs along the medial aspect of the arm.
Deep veins, on the other hand, are located deeper within the tissue and are not visible from the surface. The deep veins of the upper extremity include the axillary vein, which runs through the armpit and connects to the subclavian vein, and the brachial vein, which runs along the inside of the arm and connects to the axillary vein.
Both the superficial and deep veins of the upper extremity are important for maintaining proper blood flow and circulation. However, the deep veins are especially vital as they are responsible for carrying the majority of the blood from the upper extremity back to the heart.
The upper extremity veins also have a number of important functions beyond just transporting blood. They help to regulate blood pressure and can act as a reservoir for excess blood during times of stress or physical activity. In addition, the veins of the upper extremity are essential for the administration of intravenous fluids and medications.
Overall, the anatomy of the upper extremity veins is complex and plays a crucial role in the proper functioning of the circulatory system. Proper care and attention to these veins is essential for maintaining good health and preventing problems such as vein damage or thrombosis.
Upper limb anatomy: Bones, muscles and nerves
At the cubital fossa on the anterior aspect of the elbow joint , this vein flows into the median cubital vein. Median vein of the forearm The median vein of the forearm begins from the palmar venous network and ends in any one of the veins in front of the elbow, mostly in the median cubital vein. Sometimes it communicates with the external jugular vein by a branch which ascends in front of the clavicle. Â The cephalic vein ascends along the forearm and communicates with the The basilic vein similarly ascends within the subcutaneous tissue of the medial aspect of the forearm and inferior portion of the arm. A few imperfect valves are found in the azygos vein; but its tributaries are provided with complete valves.

The internal jugular vein receives blood from the deep structures of the neck and the brain. Anticoagulation may be considered in non-ancer patients for progression with significant extremity symptoms. Kenhub does not provide medical advice. The definitive finding is the inability to collapse the thrombosed vein with probe pressure. Deep vein thrombosis associated with central venous catheters - a review. All these veins may play an important role in supplying collateral flow in the presence of subclavian and axillary vein thrombosis.
Duplex Scanning for Upper Extremity Veins
Upper-extremity deep vein thrombosis. The Bronchial Veins vv. At the border of the teres major, the vein moves deep into the arm. The median cubital vein is a common site of venepuncture. The superficial veins connect via a network of interlacing branches to eventually form the dorsal venous network on the back of the hand. Paradoxical embolism to the arterial circulation may occur in the presence of a patent foramen ovale causing stroke or acute ischemia elsewhere.
Veins of the upper limb
The superficial veins are placed immediately beneath the integument between the two layers of superficial fascia. Its ease of access, fixed position and superficial position make the median cubital vein a good site for venepuncture in many individuals. It measures about 7 cm. Palmar metacarpal veins extend along either side of the Dorsal metacarpal veins, as previously mentioned, are formed by the union of the dorsal digital veins and receive venous blood from the fingers. The external jugular vein drains blood primarily from the scalp and face. Illig KA, Doyle AJ.
Veins of the upper limb: Anatomy
D-dimer may be useful to rule out thrombosis, but the high false positive rate gives it a poor positive predictive value. Takeaway: Veins of the upper limb consist of arm veins, and forearms veins. The most prominent and anatomically consistent superficial veins are the cephalic analogous to the saphenous and basilic. The left internal jugular vein, which is usually smaller in caliber than the right internal jugular vein, crosses the common carotid artery before joining the left subclavian vein to form the left innominate vein, which then crosses the innominate artery to form, together with the right innominate vein, the superior vena cava. Continue from the axillary vein checking in transverse that the basilic and brachial veins of the upper arm are compressible. Exercising the limb and tapping vigorously over the vein can be helpful.
The Veins of the Upper Extremity and Thorax
Main deep veins of the upper limb include the superficial and deep venous palmar arches, the radial and ulnar veins, anterior and posterior interosseous veins, the brachial veins and the axillary vein. It is a superficial vein that is located anteriorly to the cubital fossa region. Basilic Vein The basilic vein originates from the dorsal venous network of the hand and ascends the medial aspect of the upper limb. Clinical anatomy of the veins of the upper limb The median cubital vein is the vein of choice for intravenous injections, for withdrawing blood from donors, and for The cephalic vein frequently communicates with the external jugular vein utilizing a small vein crossing in front of the clavicle. They are the radial and ulnar veins in the forearm, the brachial veins in the upper arm, the axillary vein, and finally the subclavian vein. This is usually for the purpose of providing intravenous therapy e. UE DVT has less associated morbidity than lower extremity DVT Table 2.
Veins of upper limb
In order for an upper extremity venous thrombus to be considered a DVT the clot has to seen within the internal jugular IJV , subclavian, axillary or brachial veins. The radial veins are smaller than the ulnar and receive the dorsal metacarpal veins. The commonest place for blood taking is the median cubital vein, which is a small vein connecting the basilic and cephalic vein in the anterior region of the elbow. It is formed by paired veins, which accompany and lie either side of an artery. Basilic Vein The basilic vein originates from the dorsal venous network of the hand and ascends the medial aspect of the upper limb.
Arm veins normal
There are two sets of veins in the upper extremity. A large oblique branch frequently connects the basilic and cephalic veins on the back of the forearm. Deep veins of the hand typically follow the arteries of the hand and include the dorsal and palmar metacarpal veins as well as the superficial and deep palmar arches. They drain into a venous plexus which is situated over the thenar and hypothenar eminences and across the front of the wrist. In its course it describes a slight curve, the convexity of which is to the right side. Duplex scan findings of central vein stenosis or occlusion include increased velocity, post-stenotic turbulence, and continuous flow downstream. Images courtesy of the D.
Venous Disease of the Upper Extremity
Kearon C, Akl EA, Comerota AJ, et al. The brachial veins vv. These continue proximally as superficial and deep palmar arches. Veins of the forearm Much like the veins of the hand, venous drainage of the forearm is achieved through a system of superficial and deep veins. Around the foramen magnum they form an intricate net-work which opens into the vertebral veins and is connected above with the occipital sinus, the basilar plexus, the condyloid emissary vein, and the rete canalis hypoglossi. The basilic vein is the typical location for insertion of PICC lines, thrombosis can be seen in up to 70-80% according to some studies, especially the longer the line is in place.
