腎静脈圧迫による腎出血の1例

Abstract

Despite a careful search of the many literatures of the superior mesenteric artery syndrome, there were little available data on the concomitant symptoms or signs of the renal vein compression. Recently we found the case showing "nutcracker" phenomenon with macroscopic hematuria. The patient was a 19-year-old man with the chief complaint of asymptomatic macroscopic hematuria. Cystoscopic finding showed blood spurting from the left ureteral orifice. The abdominal aortography and the selective left renal venography showed that the left renal vein lay in the fork between the abdominal aorta and the superior mesenteric artery and was compressed by these vessels. Clinically this case was diagnosed as the left renal bleeding due to "nutcracker" phenomenon.
