研究目的:

主要目的:评估下肢动脉硬化闭塞症患者介入治疗前后微血流灌注变化,以明确治疗对微血流灌注的改善情况。 次要目的:评估不同Rutherford分级的下肢动脉硬化闭塞症患者微血流灌注情况,以明确下肢缺血严重程度。  

Objectives of Study:

Main objective: To evaluate the changes in microvascular perfusion in patients with lower extremity arteriosclerotic occlusive disease before and after interventional treatment, in order to determine the improvement of microvascular perfusion resulting from the treatment. Secondary objective: To assess the microvascular perfusion status in patients with lower extremity arteriosclerotic occlusive disease of different Rutherford grades, in order to determine the severity of lower extremity ischemia.
