The diploic veins (Latin: venae diploicae) are large, valveless venous blood vessels with a thin vascular wall. Once an indication for central venous catheterization is established, the clinician has multiple sites to select from including the internal jugular vein, subclavian vein, femoral vein or a peripherally inserted central catheter (PICC). 11/2 . Case. Azygos vein. The internal jugular vein is a continuation of the sigmoid sinus. Match. The diploic veins are connected with the cerebral sinuses by emissary veins. It courses inferiorly within the carotid sheath, collecting tributaries in the neck. The right and left brachiocephalic veins are large veins that receive venous drainage from the subclavian, vertebral, and internal jugular veins on their respective sides. By the end of this module, the learner will be able to: Describe the anatomical relationship of the subclavian vein (SV) to the clavicle and its fascia, first rib, subclavian artery, brachial plexus, internal jugular vein, anterior scalene muscle, phrenic and vagus nerves, pectoralis muscles, clavipectoral fascia, and parietal pleura. The subclavian veins collect deoxygenated blood from the upper extremities and the pectoral (shoulder) girdle. Axillary vein 4. They are divided from each other by the scalenus anterior in 2 arches. It rarely rises above the level of the clavicle and possesses a pair of valves about 2 cm from . Other deep veins of the upper extremity that accompany the major arteries include the radial, ulnar, brachial, axillary veins. The subclavian, transverse cervical and suprascapular veins are accompanied by their respective arteries in the posterior triangle.

The internal jugular vein ( v. jugularis interna) collects the blood from the brain, from the superficial parts of the face, and from the neck. The subclavian artery travels laterally towards the axilla. The arterial supply to the upper limb begins as the subclavian artery. Using ultrasound can decrease the time to cannulation in addition to many of the feared complications. Thoracic duct anatomy must be understood in the context of its embryology. Subclavian steal syndrome is a rare condition causing syncope or neurological deficits when the blood supply to the affected arm is increased through exercise.Subclavian steal is secondary to a proximal stenosing lesion or occlusion in the subclavian artery, typically on the left. On the right, the subclavian artery arises from the brachiocephalic trunk. Accordingly, using this landmark in improving and simplifying subclavian vein cannulation was the purpose of this study. The subclavian arteries branch to the vertebral arteries. It arises posterior to the left sternoclavicular joint, although this may vary with study population (see Fig. The subclavian vein (Latin: vena subclavia) is a large blood vessel that arises from the axillary vein. It is usually provided with a pair of valves, which are situated about 2.5 cm. The right subclavian artery is located below the clavicle. I nternal thoracic artery. Anatomically, the venous drainage can be divided into three parts: Venous drainage of the brain and meninges: Supplied by the dural venous sinuses. Other Quizlet sets. Details. Your blood moves through a complex network of blood vessels including arteries, veins and capillaries. The left subclavian artery is the fifth branch of the aorta and the third branch from the arch of the aorta. The azygos vein is a single vein that drains the thorax and enters the superior vena cava just before it joins the heart. The primary function of veins is to transport deoxygenated blood from all parts of the body, returning it to the heart, and then on to the lungs to be reoxygenated. It is one of the deep veins of the neck. SCVT can occur from multiple etiologies and is a potentially life-threatening pathology if not treated in a timely manner.

The subclavian vein is a large blood vessel that arises from the axillary vein.It is one of the deep veins found on each side of the neck. Figure 1. The subclavian vein crosses up and over the first rib in front of the anterior scalene muscle (and is therefore not within the scalene triangle). The right subclavian artery arises from the brachiocephalic artery and its branches. The subclavius muscle is a short, triangular muscle of the thoracic wall that lies underneath the clavicle. These carry oxygenated blood up to the brain from the base of the neck. It originates from the first rib and courses laterally to insert on the undersurface of the middle third of the clavicle. Additionally, the transverse cervical and suprascapular arteries (branches of the subclavian) course through the fossa after branching from the first portion of the subclavian artery. The subclavian vein (SVC) is classified as a deep vein and is the major venous channel that drains the upper extremities.
