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 to ...
Superficial veins are often visible underneath the skin. Those below the level of the heart tend to bulge out, which can be readily witnessed in the hand, where the veins bulge significantly less after the arm has been raised above the head for a short time.
Deep veins are deeper in the body and have corresponding arteries. Perforator veins drain from the superficial to the deep veins. [16] These are usually referred to in the lower limbs and feet. [17] Superficial veins include the very small spider veins of between 0.5 and 1 mm diameter, and reticular or feeder veins. [18] Venous plexuses
Blood vessel disorder generally refers to the narrowing, hardening or enlargement of arteries and veins. It is often due to the build-up of fatty deposits in the lumen of blood vessels or infection of the vessel wall. This can occur in various locations such as coronary blood vessels, peripheral arteries and veins.
The most common form of venous access is a peripheral venous cannula which is generally inserted into veins of the hands, forearms, and occasionally feet. [1] Healthcare providers may use a number of different techniques in order to improve the chances of successful access.
Varicose veins and reticular veins are often treated before treating telangiectasia, although treatment of these larger veins in advance of sclerotherapy for telangiectasia may not guarantee better results. [18] [19] [20] Varicose veins can be treated with foam sclerotherapy, endovenous laser treatment, radiofrequency ablation, or open
The basilic vein is a large superficial vein of the upper limb that helps drain parts of the hand and forearm. [1] It originates on the medial side of the dorsal venous network of the hand and travels up the base of the forearm, where its course is generally visible through the skin as it travels in the subcutaneous fat and fascia lying superficial to the muscles.
It receives the common palmar digital veins (the veins corresponding to the branches of the superficial arterial arch). [citation needed] It drains into the superficial ulnar radial and superficial radial veins, [1] [additional citation(s) needed] and the median antebrachial vein. [2]
