血液透析动静脉内瘘狭窄的介入治疗

目的 探讨经皮腔内血管成形术（percutaneous transluminal angioplasty,PTA）治疗动静脉内瘘狭窄的疗效. 方法 20例上肢动静脉内瘘狭窄患者,对比PTA术前和术后的临床表现、透析血流量及血管造影改变. 结果 所有病例经PTA治疗后,狭窄段明显扩张,透析血流量大于220ml/min,经造影证实狭窄小于30％.结论 PTA是治疗动静脉内瘘狭窄的有效方法,其操作简单、创伤小、安全、近期效果明显.

The interventional treatment of arteriovenous fistula stenosis in hemodialysis patients

Objective To investigate the clinical effect of percutaneous transluminal angioplasty for the treatment of arteriovenous fistula stenosis in hemodialysis patients.Methods Percutaneous transluminal angioplasty was performed in 20 hemodialysis patients with arteriovenous fistula stenosis.The preoperative and post operative clinical manifestations,the blood rate flow during hemodialysis and the angiographic demonstrations were recorded and compared.Results After Percutaneous transluminal angioplasty,the stenotic segment was remarkably dilated in all patients.The blood rate flow increased to more than 220ml/min during hemodialysis.Angiographic demonstrations showed that the degree of stenosis was less than 30％.Conclusion As a simple,mini-invasive and safe technique with remarkable short-term effectiveness,percutaneous transluminal angioplasty is an valuable therapy for arteriovenous fistula stenosis in hemodialysis patients.
