Percutaneous transluminal angioplasty and vacuum sealing drainage for patients with diabetic foot and arteriosclerosis obliteration of the lower extremity / 中华普通外科杂志

ABSTRACT

Objective To study the clinical efficacy of percutaneous transluminal angioplasty (PTA) and vacuum sealing drainage technique on patients with diabetic foot and arteriosclerosis obliteration of the lower extremity.Methods Sixty-four patients were divided into two groups.Group A (32 patients) were treated by traditional methods,while 32 patients in Group B treated by vacuum sealing drainage technique in addition to percutaneous transluminal angioplasty.Results One week after surgery,ABI in group A was 0.53 ±0.17 vs 0.85 ±0.27 in group B,P =0.00.Ulcer healing rate increased from 31.25％ in group A to 81.25％ in group B,P ＜0.01.The amputation rate decreased from 56.25％ in group A to 18.75％ in group B,P =0.00.Claudication distance extended and ulcer recurrence rate in group A was 40％,while in group B it was 0,P =0.00.Conclusion The combination of PTA and vacuum sealing drainage significantly improves the prognosis of patients with diabetic foot and arteriosclerosis obliteration of the lower extremity.
