Mid term result of deep balloon angioplasty for diabetic infrapopliteal artery occlusive diseases

Abstract

Objective To investigate short and mid-term therapeutic effect of deep balloon percutaneous transluminal angioplasty (PTA) for diabetic infrapopliteal artery occlusive disease.Methods Diabetic infrapopliteal artery occlusions in 73 cases (86 limbs and 131 vessels) were recanalized using deep balloon angioplasty.Digital substraction angiography (DSA) imaging was performed.Perioperative clinical data and surgical complications was analyzed.The short and mid term therapeutic effect was observed.Results 79 of 86 (91.86％) occluded limbs were recanalized after PTA,postoperative artery perfusion improved obviously below the knee,resting pain and intermittent claudication were relieved,while skin temperature improved.The ankle brachial index was higher than that of the preoperative period.Intraoperative complications developed in 6.85％ (5/73) cases,while postoperative complications occurred in 8.22％ (6/73).There was no perioperative mortality.There were 0 cases,4 cases,9 cases,10 cases,and 13 cases respectively lost to followed up after 1,2,3,4 and 5 years.The average restenosis rate below knee artery was 16.53％,pain recurred in 28.11％,ulcer recurrence was 10.95％,and limbs amputation rate was 12.49％ in five years.Conclusions Deep balloon angioplasty is safe and effective for the treatment of diabetic infrapopliteal arterial occlusive disease as evidenced by short to mid-term follow-up results.
