An arteriovenous graft serving as a fistula for hemodialysis access. A vascular bypass is often created to serve as an access point to the circulatory system for hemodialysis. Such a bypass is referred to as an arteriovenous fistula if it directly connects a vein to an artery without using synthetic material. [citation needed]
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.
The radiocephalic arteriovenous fistula (RC-AVF) is a shortcut created between cephalic vein and radial artery at the wrist. It is the recommended first choice for hemodialysis access. However, after a period of usage, failures can occur.
Fistulectomy is a surgical procedure where a surgeon completely removes a fistula, an abnormal tract (i.e. tube) that connects two hollow spaces of the body. [1] [2] In comparison to other procedural options of treating fistulae such as fistulotomies, where a fistula is cut open (i.e. unroofed) but not completely removed, and seton placement, where a rubber band seton is passed through the ...
Deep vein thrombosis (DVT) is the formation of thrombus in a deep vein. DVT is more likely to occur in the lower extremity than the upper extremity or jugular vein. When a DVT involves the pelvic and lower extremity veins it can sometimes be classified as an iliofemoral DVT.
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 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] An arteriovenous fistula can increase preload. [8] AV shunts also decrease the afterload of the heart.
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.
