Clinical value of interventional therapy in arterial occlusive disease of lower extremities
介入治疗在下肢动脉闭塞性疾病中的临床应用价值分析

摘要

目的 探讨介入治疗在下肢动脉闭塞性疾病中的临床应用价值。方法 随机抽取50例下肢动脉闭塞性疾病患者进行分析，选取时间是2020年1月-2022年1月，对其实施导管动脉内溶栓、PTA（经皮腔内血管成形术）和选择性血管内支架置入术患者50例，探讨介入治疗在下肢动脉闭塞性疾病中的临床疗效。结果 50例患者，47例开通成功，3例完全闭塞未开通患者实施搭桥术。9例患者进行单纯溶栓，1例患者进行溶栓后给予球囊扩张成形，4例患者进行球囊扩张成形，33例患者采用球囊扩张成形及腔内支架。47例患者通过血管腔内介入治疗后45例患者症状消失，2例患者症状改善。PTA和血管内支架置入术手术后6个月3例患者在原位置再次出现狭窄；PTA和血管内支架置入术患者术后1-2年分别有5例患者出现再次狭窄。结论 下肢动脉闭塞性疾病治疗过程中采用导管动脉内溶栓、PTA、支架置入术为有效疗法，临床中需要依据患者病情选择合适疗法。

Abstract

Objective: To explore the clinical value of interventional therapy in arterial occlusive disease of lower limbs.
Methods: 50 patients with arterial occlusive disease of the lower extremities were randomly selected and analyzed. The selected time was from January 2021 to January 2022. Catheter intra-arterial thrombolysis, PTA (percutaneous transluminal angioplasty) and selective endovascular stent placement were performed on them to explore their clinical effects.
Results: after treatment, 7 of the 50 patients had a degree of patency of more than 80%, and 4 patients with complete occlusion without patency underwent bypass surgery. After PTA and stent implantation, the degree of patency ranged from 90% to 100%; After 46 patients were treated by endovascular intervention, 35 patients' symptoms disappeared and 11 patients' symptoms improved. 6 months after the operation, 2 patients had restenosis in the original position, and 1 patient had restenosis 1-3 years after the operation.
Conclusion  : in the treatment of arterial occlusive disease of lower extremities, catheter intra-arterial thrombolysis and PTA are effective therapies. In clinical practice, it is necessary to select appropriate therapies according to the patient's condition.
