Edward J. Bartle, M.D., William H. Pearce, M.D., John H. Sun, M.D., Robert B.

Fig. 1 A, 4 mm embryo (4 to 5 weeks). B, 10 mm embryo (5 to 6 weeks). Persistence of the lower left subcardinal vein leads to bilateral inferior vena cava; persistence of the left subcardinal and regression of the right subcardinal veins lead to left-sided inferior vena cava. C, 15 mm embryo (6 to 7 weeks). Persistence of the anastomotic segment leads to renal collar; persistence of the left dorsal renal vein with regression of other elements leads to retroaortic left renal vein. D, 18 to 20 mm embryo (8 weeks). Normal adult anatomy.
