Abstract:
Objective To estimate the clinical effect and application value of percutaneous transluminal angioplasty and stenting (PTAS) on patients with lower extremity atherosclerotic occlusive disease (LEAOD). Methods Percutaneous transluminal angioplasty (PAT) and PATS were performed on 127 patients with diabetic lower limb arteriosclerosis. Results Total achievement ratio was 97.64% (124/127). PTAS was failed in 3 patients, clinical symptoms disappeared or improved in 124 patients. The average ankle brachial index (ABI) before and after operation was 0.35 (0.11-0.58) and 0.87 (0.67-1.06), respectively. The difference in ABI before and after operation was significant (P<0.05). During 3-60 months following-up, arteria iliaca remained open in 53 patients, and no recurrence of clinical symptom was found. At 6, 12, 36 and 60 months after operation, the encumbered superficial femoral artery kept smooth bloodstream with a proportion of 97.78%, 91.11%, 84.44%, 75.56% in 45 patients in upper 2/3 segment and 89.66%, 79.31%, 72.41%, 65.52% in 29 patients in infer 1/3 segment, respectively. Conclusion Long-term vessel recanalization can be obtained effectively and haemodynamics index be remarkably improved with PTA and PTAS in LEAOD patients.
