The palmar venous network (VRS) is an important vascular system that ensures adequate blood flow to the palm and other superficial structures of the hand. It belongs to the type of rudimentary vascular systems of the body and is involved in the processes of maintaining optimal blood supply to the hand, arm and surface of the entire body. Knowledge of this system is required to understand pathologies, diagnose and treat diseases associated with damage to the venous network of the palm.
The palmar veins are made up of several components, including dilated veins called umbilical veins and coronates. These dilated and often thinned veins are important for regulating blood pressure and controlling blood flow. They can also be affected during strenuous activities such as standing for long periods of time, poor nutrition and other factors that can lead to various diseases such as thrombophlebitis, which occurs when the umbilical veins are blocked.
The umbilical veins pass through the palm and connect separate sections of the vascular system located on the back of the hand. They convey blood from individual parts of the hand and fingers to the center of the palm and into the main vein of the limb, where it flows into a larger vein responsible for transporting blood from the upper limb towards the large vessel and the cardiovascular system. Blood flow to different parts of the hand can change depending on the level of stress, degree of friction and other factors, resulting in changes in blood pressure in the umbilical veins. When the pressure becomes too high, it can overflow the walls of dilated vessels, forming blood clots. The importance of understanding the palmar venous network lies in its importance to overall circulation and its ability to function in several challenging physical environments. If the veins in this area of the body are not working properly, it can greatly affect your circulation and even your life. Therefore, knowledge about this system is an important aspect in medicine, sports and tasks for training the arms and hands.
