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.
A Cimino fistula, also Cimino-Brescia fistula, surgically created arteriovenous fistula and (less precisely) arteriovenous fistula (often abbreviated AV fistula or AVF), is a type of vascular access for hemodialysis.
A peripherally inserted central catheter, or PICC line (pronounced "pick"), is a central venous catheter inserted into a vein in the arm (via the basilic or cephalic veins) rather than a vein in the neck or chest. The basilic vein is usually a better target for cannulation than the cephalic vein because it is larger and runs a straighter course ...
In anatomy, a fistula (pl.: fistulas or fistulae /-l i,-l aɪ /; from Latin fistula, "tube, pipe") is an abnormal connection (i.e. tube) joining two hollow spaces (technically, two epithelialized surfaces), such as blood vessels, intestines, or other hollow organs to each other, often resulting in an abnormal flow of fluid from one space to the other.
The median cubital vein is a superficial vein of the arm. [1] It lies on the anterior aspect of the elbow, [2] in the cubital fossa superficial to the bicipital aponeurosis. It bridges the cephalic vein and the basilic vein. [3] The median cubital vein receives a number of tributaries from the anterior forearm.
In the legs, bypass grafting is used to treat peripheral vascular disease, acute limb ischemia, aneurysms and trauma.While there are many anatomical arrangements for vascular bypass grafts in the lower extremities depending on the location of the disease, the principle is the same: to restore blood flow to an area without normal flow.
Deep and superficial vein thrombosis may in turn be caused by thrombophilia, which is an increased propensity of forming blood clots. [citation needed] Arteriovenous fistula (an abnormal connection or passageway between an artery and a vein) may cause chronic venous insufficiency even with working vein valves. [citation needed]
Both the artery and the vein dilate and elongate in response to the greater blood flow and shear stress, but the vein dilates more and becomes "arterialized". In one study, the cephalic vein increased from 2.3 mm to 6.3 mm diameter after 2 months. When the vein is large enough to allow cannulation, the fistula is defined as "mature". [7]
