To assess position of right chest drain inserted into the eighth intercostal space, but is projecting over the right upper quadrant on the abdominal x-ray.
In the abdomen the chest drain has been inserted through the lower right hemidiaphragm into the right lobe of the liver.
This crosses through the right lobe of the liver to the left lobe avoiding both main branches of the portal vein.
It exits the left lobe through its inferior surface and runs anterior to the distal stomach and terminates just anterior to the hepatic flexure of the colon.
The drain is not passing through the pleural cavity.
