The Safety and Efficiency of Endovascular Treatment of Acute or Subacute Thromboembolic Occlusions of Lower Extremity.

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.
