A 54-year-old man underwent right transfemoral angiography because of left renal hematuria. During angiography, dissection of abdominal aorta and thoracic aorta was encountered. It was initiated by intramural catheter passage at the bifurcation of the internal and external iliac artery. Transaxillary aortography about one month after the first angiography showed occlusion of the dissecting space in the thoracic aorta and existence of dissecting space in the abdominal aorta. Communicating orifices between the true space and the false space existed not only at the bifurcation of internal iliac artery and external iliac artery, but also at the abdominal aorta near the left renal artery. CT 1.5 months after the first angiography did not demonstrate more improvement. Surgery was performed. It was impossible to sew up and close the orifices of the space because of the fragility of the intima. Surrounding abdominal aorta and common iliac artery were wrapped near orifices with a dacron graft. A follow-up CT obtained 3 months postoperatively showed that the dissecting space in the abdominal aorta had disappeared. Wrapping was very useful to promote organization of the dissecting space.
