We investigated the initial and midterm outcomes of Zilver PTX, which was approved in Japan for the first time. Patient population was the all-comer (71 patients, 81 limbs), which included 54.3% on hemodialysis, 58% of severe calcification, 61.7% of TASC D lesions and average lesion length was 204.7 ± 97.7 mm. MALE free ratios revealed 85.1% at 6 months and 70.1% at 1 year. Considering the study population which involved more than 50% of TASC D and hemodialysis patients, the initial and midterm clinical outcomes of Zilver PTX were feasible enough.

Renovascular hypertension (RVH) is caused from various diseases. Here, we report a case of RVH complicated with ulcerative colitis in a 40-year-old male. The contrast enhanced CT scan and angiography revealed right renal artery occlusion and developed collateral arteries. It also revealed the stenosis of left renal segmental artery and hepatic artery, obstruction of the beginning of both internal iliac arteries, and partial constriction of the abdominal aorta. FDG-PET demonstrated no uptake of FDG in large vessels. Skin and colon biopsies showed no evidence of any vasculitis. Thus, this case was very difficult to diagnose what caused RVH.

Case 1: A 30-year-old woman who was diagnosed as traumatic thoracic aortic dissection and other multiple organ injuries duringa traffic accident was performed an operation. Case 2: A 65-year-old man who was diagnosed as a ulcer-like projection (ULP) was expanded was performed an operation. In both cases, we used a fenestrated stent graft in order to preserve the left subclavian artery. By using fenestrated stent graft, it was possible to have secured a landing zone, preserving the left subclavian artery. It was suggested that fenestrated stent graft for preserving the left subclavian artery is one of the useful surgical techniques.
