TASC-D	38 (77.6%)	42 (80.8%)	0.69
Combined treatment*	32 (65.3%)	24 (46.2%)	0.05
Debridement	6 (12.2%)	5 (9.6%)	0.67
Minor amputation	14 (28.6%)	14 (26.9%)	0.85

Postoperative ABI^#	0.90 (0.67–0.94)	0.83 (0.68–0.92)	0.86
MACE^† at 30 days	2 (4.1%)	1 (1.9%)	0.61

Major amputation at 30 days	0 (0%)	2 (3.8%)	0.49

*Combined treatment: combined treatment of the femoropopliteal and the infrapopliteal sector; ^#ABI: ankle-brachial index; ^†MACE: major adverse cardiovascular events; ^&MALE: major adverse limb events; ⁺SR: single revascularization; ^μMR: multiple revascularization.
