Objective To study the clinical effect and applied value of pecutaneous transtuminl angioplasty(PTA) and pecutaneous transtuminl angioplasty and stenting( PTAS) on lower extremity atherosclerotic occlusive disease(LEAOD). Methods From May 1995 to January 2009, pecutaneous transtuminl angioplasty and stenting treatment was performed in 169arteriosclerosis obliterans LEAOD patients. Results Total achievement ratio was 97.63% (149/169).Except the PTAS treatment for 4 LEAOD patients was failed,the others were doing well for clinical symptom disappear or better, whose average ankle brachial index(ABI) were 0.11～0.58(0.37±0.19) and 0.69～1.16 (0.88±0.17) respectively. The statistical result showed a significant difference in ABI (P0.05). follow-up visiting for 3～60 months; The encumbered superficial femoral artery (63 patients in Arteria iliaca, 55 patients in middle-upper 2/3 segment of superficial femoral artery and 35 patients in meta-infer 1/3 segment) keep smooth bloodstream with a proportion of 98.53%, 92.65%, 91.18%, 89.71%; 91.67%, 86.67%, 81.67%, 73.33%; 85.37%, 78.05%, 68.29%, 56.09% respectively, the time of follow-up visit was 6, 12, 36 and 60 months. Conclusion The PTA and PTAS treatment for LEAOD was a safe and effective option. ,which could make obstructed blood vessel long-term enlighten in effect and remarkably raise the haemodynamics index.
