Endovascular treatment	Cases	Gender		Mortality		Dialysis cases	Etiology
		Male	Female	30-day mortality	Hospital mortality		ASO	TAO	Others
Aorto–iliac lesion*12)	2,569	2,122	447	12	23	285	2,548	3	17
Femoro–popliteal lesion*12)	1,834	1,300	534	7	29	498	1,824	5	4
Infrapopliteal–ankle lesion*12)	961	651	310	25	48	460	950	1	8
Others	46	30	16	2	1	22	43	2	1
Total (number of regions underwent EVT)*12)	4,768	3,636	1,132	39	83	1,026	4,727	9	28
Total (number of limbs underwent EVT)*13)	4,153	3,191	962	32	65	804	4,116	7	26

*11) Including patch plasty. *12) 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). *13) When a case underwent endovascular treatment in multiple regions, the case is counted as one case.
