＊10) Bypass surgery combined with endovascular treatment is counted in both bypass category (Table 3-2) and endovascular category (Table 3-5). ＊11) Including redo operation only. Revision surgery cases should be counted in vascular complication part (see Table 6). ＊12) Including collagen disease related vasculitis, Behçet disease, fibromuscular dysplasia. ＊13) Postoperative irreversible brain complication. ＊14) Including percutaneous transluminal angioplasty (PTA), stent, and other endovascular means such as catheter atherectomy. ＊15) Only for open surgery. ＊16) Including aorto–iliac bypass or ilio–femoral bypasses. ＊17) Including popliteal–crural (or pedal) bypass. ＊18) Cases underwent extraanatomic bypass because of graft infection should not be included in this category. Those cases are listed in vascular complication (Table 6). ＊19) A case underwent axillo–femoro–femoral crossover bypass is counted as on case. A case combined with additional contralateral side of axillilo–femoral bypass as second staged surgery is counted as 2 cases. ＊20) Including patch plasty. ＊21) When endovascular treatment performed for multiple region, the case should be counted in each region (If a case underwent endovascular treatment in both aorto–iliac and femoro–popliteal region, this case can be counted one in aorto–iliac, and one in femoro–popliteal region). ＊22) Counting the patients number. When a case underwent endovascular treatment in multiple regions, the case is counted as one case.
