Detailed Description
The Global Vascular Guideline on chronic limb threatening ischemia (CLTI) recommends using the Global Limb Anatomic Staging System (GLASS) to assess the severity of infrainguinal disease in CLTI patients. GLASS staging involves scoring the femoropopliteal (FP) and infrapopliteal (IP) segments separately. For IP segment scoring, the target artery path (TAP) is identified by the clinician based on either the least diseased or the recanalized IP path. However, this approach may lead to diverse GLASS staging results, especially for simple lesions below the knee. Additionally, the current version of GLASS does not account for multivessel IP revascularization, which may introduce subjective bias if a physician chooses different IP targets during multiple revascularization procedures.
In order to improve our understanding of the current staging system, the investigators will establish a prospective registry that collects data on conservative patients who have Chronic Limb-Threatening Ischemia (CLTI) and undergo endovascular therapy for infrainguinal lesions. To evaluate the stage of the lesions, the investigators will use two distinct IP scoring techniques. One approach will be based on the least disease IP path as identified by the pre-interventional angiogram, while the second technique will be based on the recanalized IP path preferred by the clinician. This scoring will be carried out by experienced physicians and the results will be recorded in an electronic database. Then the correlation between the major adverse limb events (such as clinical-driven target limb revascularization, major amputation, and all-cause death) with the patient's Wound, Ischemia, foot Infection (WIFI) classification, GLASS anatomic staging, calcification severity, and modified Society for Vascular Surgery (SVS) run-off score will be analyzed.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Rate of freedom from major adverse events (MAEs)
Time Frame: 12-month
|
Major adverse events (MAEs) is defined as index limb amputation above the ankle, clinical-driven target lesion revascularization (CD-TLR), or all-cause death
|
12-month
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Rate of acute procedure success
Time Frame: 72-hour after procedure
|
Acute procedure success is defined as technique success ( the achievement of final residual diameter stenosis <30% for stent and <50% for angioplasty or atherectomy by angiography at the end of the procedure and without flow-limiting arterial dissection or hemodynamically significant trans-lesional pressure gradient <10 mm Hg for endovascular revascularization ) and freedom form MAEs within 72 hours of the index procedure.

72-hour after procedure
|
Rate of freedom from clinical-driven target lesion revascularization (CD-TLR)
Time Frame: 24-month
|
Patients without clinical-driven target lesion revascularization (CD-TLR)
|
24-month
|
Rate of freedom from major adverse events (MAEs)
Time Frame: 24-month
|
Major adverse events (MAEs) is defined as index limb amputation above the ankle, clinical-driven target lesion revascularization (CD-TLR), or all-cause death
|
24-month
|
Primary sustained clinical improvement assessed by Rutherford classification
Time Frame: 24-month
|
Primary sustained clinical improvement is defined as an upward shift on the Rutherford classification to a level of claudication without the need for repeated target lesion revascularization in surviving patients without the need for unplanned amputation.
|
24-month
|
Change of quality of life assessed by Vasc quality of life scale
Time Frame: 24-month
|
Postoperative Vasc quality of life score minus preoperative Vasc quality of life score
