Ligation of the renal vein during resection of abdominal aortic aneurysm.
In resection of abdominal aortic aneurysm, ligation and division of the left renal vein may be necessary in order to expose the perirenal aorta. This manoeuvre is possible, with conservation of the left kidney function, because of the extensive venous collateral circulation of the left kidney. It is of crucial importance however, that ligation of the vein is performed close to the inferior vena cava. A case is presented where ligation of the left renal vein was performed in relation to an operation for a ruptured abdominal aortic aneurysm. After the operation there was initially dysfunction of the left kidney, and later on sepsis-induced uraemia. The renal function stabilized at a moderately reduced level. No permanent kidney damage related to the venous ligation could be demonstrated. In the literature serious renal damage has been reported in 10 cases out of 89 reported ligations of the left renal vein. Ligation of the left renal vein is thus a reasonably safe and acceptable procedure for surgical exposure in difficult aortic procedures.
