Clinical Trial Summary

Current assessment of lower limb ischemia cannot reflect the location and degree of ischemia. Tissue perfusion assessment was used in the diagnosis and treatment of lower limb ischemia in this project, and the quantitative evaluation of ischemia degree was realized by using its advantages of quantitative analysis and perfusion imaging.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Perfusion of the index leg assessed by BOLD MRI before and after endovascular intervention.	BOLD evaluates perfusion noninvasively and can be used for long-term monitoring and postoperative follow-up. Improving the perfusion assessment will improve the evaluation system for endovascular treatment of PAOD.	1 year
Primary	Perfusion of the index leg assessed by PBV before and after endovascular intervention.	PBV can evaluate intraoperative perfusion quantitatively in real time.	During operation
Secondary	The relationship between perfusion and function of the lower limb in PAOD patients	The preoperative and postoperative motor functions of the patients were tested to analyze the functional impact of perfusion improvement.	1 year
