Based on the development of new tools, including drug coated balloon, paclitaxel eluting stent, interwoven stents, debulking tools, More and more acute or subacute thromboembolic occlusions of lower extremity included stage IIb were treated with endovascular procedures. Most guidelines suggests only stage I and stage IIa lesions are suitable for endovascular treatments. Therefore, a well-designed real-world study that track the safety and clinical relevant outcomes, are required to determine the optimal therapies for patients with acute or subacute thromboembolic occlusions of lower extremity.
Patients aged 18 years or older.
Diagnosis of acute or subacute limb ischemia classified as Rutherford classification stage I to IIb.
Rutherford classification ranging from 3 to 5.
Successful guidewire passage through the lesion of the femoropopliteal artery lesion, followed by further endovascular treatment. There are no restrictions will be implemented on the methods used for guidewire passage through the target lesion. The presence of thrombus must be confirmed via angiography and/or DSA and must be associated with occlusions of the lower extremity or ISR.
Acute or subacute limb ischemia patients with Rutherford classification stage III.
Patients diagnosed with thromboangiitis obliterans.
Patients requring open surgery or hybrid operation after contrast radiography.
Patients with a history of stroke, cerebral hemorrhage, gastrointestinal bleeding, myocardial infarction, or similar conditions in the past 3 months.
