The anatomy and fascial relationships of the superficial veins was investigated by dissection in 46 inferior limbs from 23 cadavers (14 males, 9 females, mean age 62 years). Gross anatomy Origin and course. Gross anatomy Origin and course. The external iliac vein (latin: v. iliaca externa) is a large vein formed by the femoral vein. A tributary or affluent is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. The stereomicroscope Tributaries. The inferior vena cava is a large, valveless, venous trunk that receives blood from the legs, the back, and the walls and contents of the abdomen and pelvis. In human cardiovascular system: Inferior vena cava and its tributaries. Objective: We evaluated the anatomy of the infrarenal portion of the human inferior vena cava and their ventral tributaries by video laparoscopy.Study Design: A total of 112 patients underwent laparoscopic para-aortic lymphadenectomy for gynecologic malignancies. The number, dimension, angulation, and position of the coronary sinus and of its tributaries were studied. Results: Two veins are consistently present: the middle cardiac vein (mean diameter 2.62 ± 1.26 mm) and the great cardiac vein (mean diameter 3.55 ± 1.24 mm). Venous channels called venous sinuses lie between the two layers of the dura mater, the outer covering of the brain; they possess no valves.Venous drainage of the brain is effected by these sinuses and communicating vessels. Others go from cold, raging rivers to small, warm streams as the snowpack runs out, or even stop flowing completely. The splenic vein is formed by splenic tributaries emerging at the splenic hilum in the splenorenal ligament at the tip of the tail of pancreas. The coronary sinus is the gateway for left ventricular (LV) epicardial lead placement for cardiac resynchronization therapy. The great saphenous vein lies within the subcutaneous tissues of the leg in the thigh in the saphenous compartment, which is bounded posteriorly by the deep fascia and superficially by the saphenous fascia 3. It then unites with the internal iliac vein to form the common iliac vein. A tributary does not flow directly into a sea or ocean. The implanting electrophysiologist is usually challenged by a high degree of variability in the coronary venous anatomy, making it important to have a more consistent and uniform segmental approach to describe the coronary venous tree and its branches. A river’s natural ups and downs are called “pulses.” Like a human being’s pulse, a river’s natural flow of water is life support for animals, plants, and fish, delivering what The thoracic duct receives lymph from, roughly, both halves of the body below the diaphragm and the left half above the diaphragm. It runs in the splenorenal ligament in close association with the splenic artery. It begins above the level of the inferior margin of the inguinal ligament, enters the pelvis, ascends medially along the psoas major. Background The intraoperative anatomy of the saphenofemoral junction can vary from the 'textbook' description of six independent proximal tributaries: three medial - superficial external pudendal, deep external pudendal and the posteromedial thigh branch - and three lateral - superficial epigastric, superficial circumflex iliac and the anterolateral thigh branch.
