A middle-aged patient came to control kidney cysts. At ultrasound the cysts does exist, but after examining the bladder, the probe slid a little higher and a rather strange view appeared, the first thought that came to me was a aortic dissection, but no. As a result, I came to the conclusion that this is an anomaly of the caudal aorta, i.e. its final part, in the area of bifurcation. Moreover, the bifurcation goes to the left, then the right common iliac artery makes slightly less than 360 degrees above the aorta, and the left one also makes a loop more than 360 degrees of a smaller diameter. The patient was recommended abdomen CT. Ps. As already described in the literature, such anomalies have significance in interventional cases, in particular when using access via the femoral artery, such as CAG (coronary angiography). external link |
