Methods From January to May, 2009, four diabetic patients with vascular lesions of lower extremities were examined by Doppler ultrasonography and digital subtration angiography (DSA). All patients were treated by percutaneous transluminal angioplasty (PTA) or stenting therapy. Results Stenoses and obstruction of lower extremity blood vessels were observed in all patients. After intervention therapy, vascular perfusion of lower extremities was improved and signs of rest pain and intermittent claudication were relieved; the skin temperature was improved, and the amputation level was apparently decreased. Conclusion It suggests that DSA is effective in judging extend and location of blood vessel stenosis,and the interventional treatment could lead to a satisfying prognosis.
