Objective To study the effect of the intracavity thrombolysis, aspiration of debris, percutaneous transcathete angioplasty (PTA) and percutaneous transtuminl angioplasty and stenting (PTAS) on treating peripheral arterial obliterans disease (PAOD). Methods From May 1994 to May 2008, interventional treatment was performed in 285 patients with PAOD. Intracavity thrombolysis and aspiration of debris were performed in 63 patients suffering from acute arterial occlusion. Intracavity thrombolysis and PTA were performed in 61 patients suffering from arteriostenosis combined with acute occlusion. Intracavity thrombolysis, PTA and PTAS were performed in 161 patients suffering from chronic arteriostenosis occlusion. Results Total success rate was 98.25% (280/285). The success rate in intracavity thrombolysis and aspiration of debris was 96.83% (61/63), with 88.89% (56/63) of the blood vessels restored, 7.94% (5/63) of the blood vessels partially restored, and another 3.17% (2/63) failed. The success rate in intracavity thrombolysis and PTA was 85.25% (52/61). The success rate in PTA and PTAS was 98.14% (158/161). The total complication rate was 7.02% (20/285), of them the local thrombolysis and thromboclasis accounting for 7.94% (5/63), the local thrombolysis and PTA accounting for 14.75% (9/61), the PTA and stent implantation accounting for 3.73% (6/161). Conclusion Percutaneous transluminal treatment for stenotic and occlusive lesions of peripheral artery can effectively keep the blood vessel unobstructed for a long time and raise the haemodynamics index remarkably.
