The carpal communicans dorsalis vein, also known as the dorsal carpal vein, is one of the veins that forms the vascular bed in the hand. It connects the dorsal venous network of the wrist with the dorsal venous network of the forearm.
The communicating dorsal carpal vein originates in the dorsum of the wrist, from the dorsal vein of the hand, and passes through the carpal tunnel, where it divides into two branches: the dorsal and palmar carpal veins.
The dorsal branch runs along the dorsum of the dorsum of the wrist and joins the dorsum of the forearm, where it joins the dorsal veins of the forearm to form the dorsal venous canal.
The palmar branch of the carpal communicating dorsal vein runs along the palmar surface of the palm and connects with the palmar branch of the forearm, which is also part of the dorsal venous canal.
The carpal communicating dorsal vein plays an important role in the blood supply to the hand and forearm. It drains blood from the back and palm of the hand and forearm, and also transfers nutrients and oxygen to these areas.
Impaired function of the carpal communicating dorsal vein can lead to swelling, pain, and other symptoms associated with poor circulation. However, overall, this vein is an important element of the venous system of the hand and forearm and plays an important role in maintaining the health and function of these areas.
