A 32-year-old woman underwent an autologous saphenous vein-covered stent deployment for the treatment of a saccular aneurysm on the distal renal artery. Complete exclusion of the aneurysm was immediately obtained. One year after the treatment, remarkable shrinkage of the aneurysm was demonstrated by means of computed tomography, and wide patency of the renal artery and the stent was shown by means of angiography.

We evaluated the clinical features and the risks of 14 patients with saphenous vein thrombophlebitis from April 2007 to May 2013 and compared the results with patients under operation for varicose veins during the same period (127 patients, 193 limbs). The rate of patients with higher body mass index (over 25) (78.6% vs. 35.3%, p = 0.0018), varicose change of saphenous vein (78.6% vs. 6.2%, p < 0.0001), and concurrent existence of thrombosis of other veins (50.0% vs. 7.1%, p < 0.0001) were all significantly higher than those of patients under operation for varicose veins. These patients with clinical features above may be at the risk of thrombophlebitis.
