Therapeutic effect of percutaneous transvascular stent on senile lower extremity arteriosclerosis obliterans

Abstract

Objective To observe the curative effect of percutaneous transvascular stenting on elderly patients with lower extremity arteriosclerosis obliterans. Methods A retrospective analysis of 46 patients with lower extremity arteriosclerosis obliterans admitted to Shenzhen Hospital of Traditional Chinese Medicine from July 2014 to January 2018 was made. The patients were randomly divided into control group and observation group, with 23 cases in each group. Percutaneous balloon angioplasty was used in the control group, and percutaneous balloon angioplasty and stenting were used in the observation group. The clinical effects and complications of the two groups were compared. And the ankle brachial index and claudication distance were compared, when the patients had been followed up for 6 months and 12 months. Results The clinical effective rate of the observation group (95.65%) was higher than that of the control group (73.91%), and the difference was significant(P<0.05). The incidence of complications in the observation group (4.35%) was lower than that in the control group (26.09%), and the difference was significant (P<0.05). The sputum index and the sacral distance 6 months and 12 months after treatment in the two groups were significantly improved with the prolongation of the postoperative time. The sputum index and the claudication distance of the observation group were significantly higher than the control group, and the difference was significant (P<0.01). Conclusions In elderly patients with lower extremity arteriosclerosis obliterans, percutaneous balloon angioplasty combined with endovascular stenting can effectively improve the clinical treatment effect, reduce the incidence of postoperative complications, and improve the postoperative index and claudication distance with ideal effects.
