Abstract
We present a case of an 80-year-old male who had a right buttock claudication after embolization of the right internal iliac artery and endovascular aneurysm repair (EVAR) for aneurysms of the right common iliac and abdominal arteries. We used follow-up dynamic computed tomography to measure the diameter of the superior gluteal artery (SGA). The comparison ratio (SGA diameter after EVAR / SGA diameter before EVAR) of the right SGA at 1, 3, and 9 months was 0.74, 0.80, and 1.1, respectively, while that of the left SGA at 9 months was 0.97. The patient reported using a walking stick at 1- and 3-month follow-ups but not at the 9-month follow-up. The computed tomography (CT) showed sequential dilatation of the SGA, which appeared to be associated with the relief of the buttock claudication.
