Inferior venacaval obstruction clinical features

IVC obstruction features are the following
  • Dilated veins seen over the abdomen and chest. 
  • Direction of flow is from below upwards and look for the direction below the umbilicus. 
  • These represent dilated anastomotic channels between the superficial epigastric and circumflex iliac veins below, and the lateral thoracic veins above, they convey  the diverted blood from long saphenous vein to axillary vein
How abdominal wall wins are formed in IVC obstruction ?
These are dilated anastomotic channels formed between the superficial epigastric and circumflex
iliac vein below, and the lateral thoracic veins above, carrying blood from long saphenous vein to axillary vein. This Is why the direction of blood flow is from below upwards.
