The interventional therapy for diabetic peripheral artery disease

Background: Diabetic peripheral arterial disease is the main cause of lower limb amputation in patients with diabetes. To summarize the technique and experiences and evaluate the clinical effects of blood vessel intervention operation on diabetic peripheral artery disease. Methods: 81 patients with diabetic peripheral artery disease from October 2007 to September 2011, 81 cases of the observation group were treated by balloon PTA. By adopting the Seldinger puncture technology, intubation was placed into a cobra catheter or a pig tail artery catheter and directed to the ipsilateral lower extremity artery. A guidewire was used to reach the lesion part of patients and a long balloon with a diameter of 4-6 mm was used to expand the artery with a pressure of 6-10 atm. Results: 81 patients in the observation group received the PTA surgery. The technical succesful rate was 100%, no complication happened. The skin temperature increased after treatment. The blood supply improved significantly. The pulsation of the foot dorsal artery was strengthened. The numbness and pain symptoms were moderated significantly. We observed better results in the observation group in lower limb vessel diameter and foot ulceration healing. None of the patients received amputation surgery. Its short-term effects were satisfactory. Conclusion: PTA is a feasible technique for diabetic peripheral artery disease. It has great clinical significance in treating diabetic peripheral arterial disease. Although its short-term effects is satisfactory, the long-term effects is necessary for follow up.
