To the Editor.—In our article in the July issue of the Archives (107:66-68, 1973), the mortality for patients who underwent surgical interruption of the inferior vena cava was listed as 4%. This is misleading as the 4% reflects only the mortality from recurrent pulmonary emboli. The mortality from all causes within 30 days of operation was 17% as outlined in another article (unpublished data).
