​Renal Artery or Vein Thrombosis

Renal artery or vein thrombosis is the blockage of the renal artery (which brings blood to the kidney) or renal vein (which carries blood away from the kidney) due to the formation of a blood clot. This causes malfunctioning of the kidney which can lead to high blood pressure and kidney failure if it is not treated immediately. In children, most cases of renal artery or vein thrombosis occur due to severe dehydration, which allows the blood to clot more readily. Dehydration can be caused by diarrhoea. 90% cases of renal vein thrombosis occur in infants less than a year old while 75% of the cases occur in babies less than a month old.
