PURPOSE
To exploit the potential benefits of percutaneous transluminal angioplasty (PTA) in patients with short obstructive lesions in the lower extremity, it is preferable to select patients suitable for PTA before proceeding to hospital admission and angiography. The aim of this prospective study was to evaluate the role of color-coded duplex scanning in the correct selection of patients for PTA and its influence on planning the approach to the lesion.
METHODS
On the basis of clinical history, physical examination, pressure indices, and ultrasound duplex scanning, 109 patients were scheduled for PTA.
RESULTS
The indication for PTA was correct in 103 patients (94%), while the procedure was performed successfully in 98 patients (90%). The approach to the lesion was planned successfully in the majority of patients.
CONCLUSION
This study shows that it is justifiable to plan PTA on the basis of information obtained by duplex scanning. Results of the duplex scan may guide the catheterization route.
目的
为了在患有下肢短段阻塞性病变的患者中利用经皮腔内血管成形术（PTA）的潜在益处，在进行住院和血管造影之前，最好选择适合PTA的患者。这项前瞻性研究的目的是评估彩色编码双功扫描在正确选择PTA患者中的作用及其对规划病变治疗方法的影响。
方法
基于临床病史、体格检查、压力指数和超声双功扫描，109例患者被安排进行PTA。
结果
103例患者（94%）的PTA适应证正确，而98例患者（90%）手术成功。大多数患者的病变治疗方法规划成功。
结论
本研究表明，根据双功扫描获得的信息来规划PTA是合理的。双功扫描结果可指导导管插入路径。
