The peripheral vascular system is the part of the circulatory system that consists of the veins and arteries not in the chest or abdomen (i.e. in the arms, hands, legs and feet). [ 1 ] [ 2 ] The peripheral arteries supply oxygenated blood to the body, and the peripheral veins lead deoxygenated blood from the capillaries in the extremities back ...
A communicating vein directly connects two parts of the same system such as the Giacomini vein that connects the (superficial) small saphenous vein with the (superficial) great saphenous vein. Peripheral veins carry blood from the limbs and hands and feet.
Peripheral artery disease most commonly affects the legs, but other arteries may also be involved, such as those of the arms, neck, or kidneys. [4] [17] Peripheral artery disease (PAD) is a form of peripheral vascular disease. Vascular refers to both the arteries and veins within the body. PAD differs from peripheral veinous disease. PAD means ...
Venous insufficiency is the most common disorder of the venous system, and is usually manifested as either spider veins or varicose veins. Several treatments are available including endovenous thermal ablation (using radiofrequency or laser energy), vein stripping , ambulatory phlebectomy , foam sclerotherapy , laser , or compression.
If the impaired vein function causes significant symptoms, such as swelling and ulcer formation, it is referred to as chronic venous disease. [3] It is sometimes called chronic peripheral venous insufficiency and should not be confused with post-thrombotic syndrome in which the deep veins have been damaged by previous deep vein thrombosis.
The tunica media may (especially in arteries) be rich in vascular smooth muscle, which controls the caliber of the vessel. Veins do not have the external elastic lamina, but only an internal one. The tunica media is thicker in the arteries rather than the veins. The outer layer is the tunica adventitia and the thickest layer in veins. It is ...
A peripheral venous catheter is the most commonly used vascular access in medicine. It is given to most emergency department and surgical patients, and before some radiological imaging techniques using radiocontrast, for example. In the United States, in the 1990s, more than 25 million patients had a peripheral venous line each year. [2]
Midline access is a type of peripheral venous access inserted into peripheral veins and that extends further than standard peripheral catheters but does not yet reach the large central veins of the thorax. They are used when intermediate-term access (one month) is needed or when administering medications that are highly irritating to smaller veins.
