Recently interventional radiologic procedures for vascular occlusive diseases have become an alternative to the surgical method. Percutaneous transluminal angioplasty(PTA) is an effective treatment for a short, concentric, segmental, stenotic lesion. The patency rate of PTA depends on the nature of the lesion. The long-term patency rate is high in iliac artery lesions. Percutaneous stent placement is an effective long-term treatment for patients with iliac insufficiency. New stents, such as a drug-coated, radioactive stent, are under investigation to overcome the re-stenosis after PTA or stent insertion. Percutaneously placed endoluminal stent-grafts for treatment of abdominal aortic aneurysm were developed to avoid major intraabdominal surgery and related morbidity and mortality.

BACKGROUND: Recently, cardiopulmonary exercise testing (CPX) has become a popular diagnostic method for differentiating the main cause of exertional dyspnea or exercise limitation. We evaluated the difference in the CPX results according to interpretative algorithms and the methods of exercise in Korea. METHOD: Sixty-six patients with chronic lung disease and 48 adults with dyspneic symptoms, but with no abnormalities in a spirometry performed symptom limited CPX, were included in this study. The results were interpreted using both Wasserman's(WA) and Eschenbacher's algorithm (EA), and a comparison between both algorithms was made. Thirty-three healthy medical students performed the CPX with a cycle ergometer and treadmill. The results were interpreted with EA and the concurrenec in interpretations was evaluated according to the methods of exercise. RESULTS: 1. In patients with chronic lung disease, the overall concordance rate between the two algorithms was 63.6%. The concordance rates were 69.8% in patients with obstructive, 25.0% in those with restrictive, and 66.7% in those with mixed pulmonary insufficiency. In patients with dyspneic symptoms but normal findings in resting spirometry, the concordance rate was 60.4%. 2. In healthy medical students, in results interpreted with EA, the concordance rate between the cycle ergometer and treadmill exercise was 25.0%. CONCLUSION: Both interpretative algorithms and methods of exercise may affect the CPX results. In using CPX as a diagnostic test for the causes of dyspnea in the Korean population, the interpretative algorithms and method of exercise need to be standardized, and a predictive VO2max equation needs to be established.
