Vein Vava Upper Left

Vena cava superior left - (V. Cava Superior Sinistra). Venous artery of the upper half of the body. Supplies blood to all organs of the chest, the upper part of the abdominal cavity and part of the chest cavity. The left superior sinus, also known as the superior lateral vein in human anatomy, is a paired vessel that drains into the superior vena cava, receiving blood from the liver, stomach, spleen, pancreas, gall bladder, kidneys, adrenal glands and all abdominal organs. In the systemic circulation, the left superior sinus is the largest artery. The name is associated with its location behind the sternum. The sinus is located to the left and superior to the esophagus, closely adjacent to the T4 vertebra. The anatomical position of the upper left sinus varies slightly among people of different heights and body compositions. “Sinus” is not a venereal disease term (unlike, for example, “sinusoidal motion” or “cavity of sinusoids” used in nuclear medicine). It describes the anatomical structure of the vessel (the line responsible for the movement of blood in the vessel) and has nothing to do with its origin. Its name in Russian is a literal translation from Latin using the term Anatomicus Latinus.

When referring for surgery, it is necessary to clarify in advance the location of the patient’s sinuses. Caution must be maintained during surgery as gas insufflation can only be performed above the T5 vertebral level. Intraoperative trauma can occur at the point where the needle enters the patient’s body, as well as upon contact with “provocative” organs located next to the vessel: stomach, bladder, aorta, etc. According to some studies in the field of neurosurgery, dysfunction of the “left venous sinus” leads to abdominal pain. If you experience pain in the lower abdomen or lower back, you should immediately consult a doctor. When puncturing the left superior vein, excessive accumulation of blood is allowed. It is recommended to perform repeated punctures after dilatation of the internal diameter of the left upper sinus. After puncture, the vessels are fixed with special clamps.
