Primary Outcome Measures:
  • Occlusion of the below-knee artery or bypass [ Time Frame: 36 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Mortality [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
    The number of death during the first month after procedure, no matter whether the cause of death is related to the procedure.

  • Rate of limb salvage [ Time Frame: 36 months ] [ Designated as safety issue: Yes ]
  • Procedural complications, defined as any adverse event [ Time Frame: 36 months ] [ Designated as safety issue: Yes ]
    including MI, DVT, hematoma, renal failure, wound infection, lymphatic fistula

  • Quality of Life assessment [ Time Frame: 36 months ] [ Designated as safety issue: Yes ]
    assessment in 1 month,6 months,12 months,24 months and 36 months post procedure

  • Restenosis measured by Duplex Ultrasound or CTA [ Time Frame: 36 months ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: PTA
The patients with short-obstruction in the below-knee artery will be included in this group.
Device: Percutaneous Transluminal Angioplasty
Before operation, take aspirin 100mg every day. During the operation, balloon is delivered by a catheter and positioned through the narrowing in the artery. Then expand the balloon against the wall of the blood vessel to provide a wider channel for blood.
Experimental: bypass
The patients with long-obstruction in the below-knee artery will be included in this group.
Device: below-knee arterial bypass
Before operation, take aspirin 100mg every day. Perform bypass to below-knee(posterior tibial,anterior tibial or peroneal)arteries, saphenous vein graft with end to side anastomoses

Detailed Description:

The trial includes two parts and here is part II. This part is a multi-center, prospective, registration study which focuses on the treatment of below-knee arterial lesion. Totally 130 patients will be entered into this part. They should suffer ischemic symptom with Rutherford 3-6 for the occlusion of the below-knee arteries(anterior tibial、posterior tibial or peroneal artery). According to the lesion length, the patients will accept transluminal angioplasty or below-knee arterial bypass. They will be followed up for 3 years. Study examinations will be done at screening, procedure time, 1, 6, 12, 24 and 36 months after procedure.
