A method of translumbar aortography to get clear image was introduced in 67 cases with the following results. 1) Obstruction of the blood flow to the lower extremities was caused by compression on the lower abdomen with a rediolucent bag used for excretory urography on the abdomen. It was noted that the compression pressure was required to be as high as to make the systolic pressure of the arm, being 40 mmHg., higher than that of the leg. 2) Radiographic exposure was made 0.5 to 3.0 seconds after the commencement of the injection of the contrast medium, but the clearest picture was obtained when the exposure was made 0.5 to 2 seconds. 3) In this method a clear arteriogram was obtained in 83.6 percent, whereas in the existing translumbar aortography only 53.5 percent. 4) It was noted that a clear renal arteriogram was obtained, when the injection of the contrast medium was made into the aorta less than 3 cm above the ramification of the renal artery. In the existing aortography it was difficult to get a clear aortogram, when the injection was made below than the ramification of the renal artery, while with our method a clear picture was obtained, when the injection was made at 2 cm lower than the remification. 5) In this method only a case of shock due to local anesthesia was experienced, but never was found in the cases in which this method was performed. Some cases showed a fall of the blood pressure when compression was taken off.
