Occurrence of valves in the main trunk of the renal vein

Abstract: The increasing use of selective angiography in modern roentgenologic diagnostics has indicated the need for more detailed anatomical information. Both the renal and gonadal veins have in recent years been subjected to investigation from the roentgenologic as well as from the clinical and physiologic points of view (HELANDER et colI. 1958, EDWALL 1958, HELANDER & LINDBOM 1960, FUCHS 1961, AHLBERG et colI. 1965, 1966). Information on the valves varies in the literature. A number of authors describe the presence of valves in the renal veins (HENLE 1868, RIVINGTON 1873, GEGENBAUER 1903, FAGARASANU 1938, and KUGELGEN & GREINEMANN 1957), while others deny their existence (LUSCHKA 1863, GLANTENAY & GOSSET 1904, MOLLENDORFF 1943, DALLA PALMA & SERVELLO 1956, GILLOT et coll, 1960, and BARRY et call. 1962). The majority of the authors who have observed valves in the renal veins have given no frequency figures, the exceptions being RIVINGTON, and FAGARASANU, who investigated ten and thirty autopsy cases, respectively. The former found valves on the right side in three and on the left side in two cases, while the latter observed valves on the right side in twenty-one cases and on the left in eleven cases. It has been stated that the left gonadal vein with few exceptions empties into
