To the Editor.—
The letter from Drs Jennings and Glucksman (213: 1905, 1970) introduced a case demonstrating that renal vein ligation, unlike thrombosis, was without deleterious effect. They could find no report of this fact. Nevertheless there are a number of references to division of the left renal vein in man. First described by Erlik et al1 in 1964, they and others2-4 later have presented a series of cirrhotic individuals in whom the vena caval stump was used for portarenal anastomosis with no detectable harm to the kidney. Three years ago Gonzalez et al5 reported in The Journal that, during removal of a pheochromocytoma, they ligated the left renal vein of their patient without permanent sequelae. About the same time, Neal and Shearburn6 recommended division of the left renal vein as an adjunct to resection of abdominal aortic aneurysm, having performed this maneuver in 11 patients.
