Accessory right inferior hepatic vein

An accessory right inferior hepatic vein is the most common variation of the hepatic veins.  It is present in up to 48% of the population and drains the posterior part of the right lobe (mainly segments 6 and 7) directly into the inferior vena cava. Variations in hepatic vascular anatomy are pa...

Superficial middle cerebral vein

The superficial middle cerebral vein (SMCV) (also known as the Sylvian vein) is one of the superficial cerebral veins. It usually passes along the Sylvian fissure posteroanteriorly, it collects numerous small tributaries which drain the opercular areas around the lateral sulcus. It curves anteri...

Ascending lumbar communicant vein

The ascending lumbar communicant vein is a communication between the left ascending lumbar vein and the left renal vein. Because of its retroperitoneal location, when dilated, it may be mistaken for a lymph node on non-contrast studies with thick collimation. The image shows the left renal vein...

Total anomalous pulmonary venous return

Total anomalous pulmonary venous return (TAPVR) is a cyanotic congenital heart anomaly with an abnormal drainage anatomy of the entire pulmonary venous system. This contrasts with partial anomalous pulmonary venous return (PAPVR) where only part of the pulmonary venous anatomy is abnormal. In T...

Left gastric vein

The left gastric vein (also known as the coronary vein) drains both gastric walls. It forms a loop with the right gastric vein at the lesser curvature of the stomach. The left gastric vein travels in the lesser omentum to drain in the portal vein. It also communicates with the lower esophageal v...

Superior mesenteric vein

The superior mesenteric vein (SMV) accompanies the superior mesenteric artery (SMA) and drains the midgut to the portal venous system. Gross anatomy Origin and course Mesenteric venous arcades, which accompany the arteries, unite to form the jejunal and ileal veins in the small bowel mesenter...

Pulmonary veins

The pulmonary veins drain oxygenated blood from the lungs to the left atrium. A small amount of blood is also drained from the lungs by the bronchial veins Gross anatomy There are typically four pulmonary veins, two draining each lung: right superior: drains the right upper and middle lobes ...

Great saphenous vein

The great saphenous vein (GSV) forms part of the superficial venous system of the lower limb.  Terminology The great saphenous vein is the preferred term over other variants such as long saphenous vein (LSV), greater saphenous vein or internal saphenous vein 5. Gross anatomy Origin and cours...

Small saphenous vein

The small saphenous vein (SSV) forms part of the superficial venous drainage of the lower limb. Terminology Small saphenous vein is the preferred terminology over other terms such as short saphenous vein, external saphenous vein or lesser saphenous vein 5.  Gross anatomy Origin and course T...

Venous drainage of the lower limb

The anatomy of the venous drainage of the lower limbs is extremely variable. However, there is order in the variability. The veins of the lower extremities are arranged in three systems: the superficial, the deep, and the perforating venous systems. These are located in two main compartments: th...

Perforating veins of the lower limb

The perforating veins of the lower limb (PV or “perforators”) are so called because they perforate the deep fascia of muscles, to connect the superficial venous systems of the lower extremity to the deep veins where they drain. There are numerous veins that are variable in arrangement, connectio...

Perforators of the leg and calf (venae perforantes cruris)

The perforators of the leg (venae perforantes cruris; PV; or “perforating veins”) are a subset of, and not to be confused with, the larger overarching group of perforating veins of the lower limb. This group of veins connects the superficial venous systems and deep veins in the calf and are div...
