Hi,

I was looking over a CT abdomen/pelvis done on myself, that was in my med file dated 03/04/03.
The reader made a special note and I would like to know what it means or could mean, or , why :

"Left renal vein running posterior to aorta to join inferior vena cava."

Thanks for your help.. I just need to know if this is unusual or common :?: ...

It is unlikely that this will cause any problems. This is a slight anomaly in that the left renal vein normally passes in front of the aorta, but in some individuals it goes behind as in this case.

Have a look at: http://en.wikipedia.org/wiki/Renal_vein for a picture.

The kidney is the organ with the most number of variations in development. it is common to find variations in number, shape, size, location of the ureters, number of ureters etc.

Hope this helps.

Thank you kindly. Yes, this does help. I have always had low blood pressure . I was wondering if this may have something to do with it? I'll ask the Specialist next time I see her. Would you consider this a "defect" or, is it quite common?

It is a variant seen in some people.

The problem is that there could be lots of individuals with this anomaly, just that most people do not have a CT scan to find it. If patients do not have a problem, defects like this never get discovered. The majority of people that have 3 or 4 kidneys instead of 2 live a normal life and are never diagnosed....

Hi...normaly left renal vein should be infront of aorta just below the superior mesentric ostia...being of L.Renal vein behind the aorta may cause hypoperfution to left kidney leading to chronic renal failure....

The renal arteries normally arise off the side of the abdominal aorta, immediately below the superior mesenteric artery, and supply the kidneys with blood. Each is directed across the crus of the diaphragm, so as to form nearly a right angle with the aorta.

The renal veins are veins that drain the kidney. They connect the kidney to the inferior vena cava.
It is usually singular to each kidney, except in the condition "multiple renal veins".[1]
It also divides into 2 divisions upon entering the kidney:
* the anterior branch which receives blood from the anterior portion of the kidney and,
* the posterior branch which receives blood from the posterior portion.
