Abstract:

Objective To investigate the efficacy and safety of chocolate balloon dilatation angioplasty on diabetic patients with infrapopliteal artery occlusion. Methods Fifty-six diabetic patients with infrapopliteal artery occlusion from September 2020 to February 2021 were selected and randomly divided into two groups with 28 patients in each group. The control group was treated with ordinary balloon for interventional treatment of percutaneous infrapopliteal artery intraluminal angioplasty, while the observation group was treated with chocolate balloon. The operative success rate, intraoperative flow limiting dissection formation were observed between the two groups; the ankle-brachial index(ABI), transcutaneous oxygen pressure(tcpO2), and symptom improvement were compared between the two groups before and after surgery. Results The success rate of technology in the observation group and the control group were both 100%, and the success rate of operation were 96.43% and 89.29%, respectively; 6 infrapopliteal arteries formed flow restriction dissections after balloon dilation in the observation group (6/39) , and 15 infrapopliteal arteries formed in the control group (15/40).The rate of intraoperative flow limiting dissection formation in the observation group was lower than that in the control group(P<0.05). ABI and tcpO2 in the observation group were significantly better than that in the control group(P<0.05). Symptoms were significantly improved after surgery in the both groups. Conclusion The application of chocolate balloon dilatation in the treatment of infrapopliteal artery occlusion is satisfactory, can effectively reduce the occurrence of flow limiting dissection, the short-term effect is more superior.
