摘要：

Objective: This study investigates the potential role of intravascular ultrasound (IVUS) in the outcome in patients undergoing percutaneous transluminal angioplasty (PTA) of the superficial femoral artery. Materials: Angiographically and the qualitative and quantitative IVUS data obtained at the narrowest site derived from 39 patients before and after PTA were analysed. Results: Angiographically the diameter of the remaining stenosis seen after PTA was classified as <50% in 31 patients (success); in eight patients a failure was encountered. Evaluating at 6 months the functional and anatomic results of the PTA in 31 patients, the intervention was a success in 14 patients (Group I) and a failure in 17 patients (Group II). The remaining eight patients defined as angiographic failure following PTA comprised Group III. Neither qualitative nor quantitative IVUS data obtained before PTA could pl effect outcome. Conversely after PTA, the extent of dissection was significantly move severe in Groups II and III than in Group I. Similarly, significant differences were found between Groups I and II for mean free lumen area (13.2 vs. 9.7 mm(2), respectively) and mean free lumen diameter (4.1 vs. 3.5 mm, respectively. Quantitative data obtained in Group II weve similar to those in Group III. Conclusion: This preliminary study demonstrates that following PTA the extent of dissection, free lumen area and diameter seen with IVUS ave predictive factors of patency. Future studies with more patients ave mandatory to further highlight the sensitivity of these observations.
