Author's reply: Systematic review of exercise training or percutaneous transluminal angioplasty for intermittent claudication (Br J Surg 2012 99 16-28)

摘要

We thank Yan and Kwong for their interest in our systematic review. We are aware and very pleased that more and larger high-quality randomized controlled trials on the relative effectiveness of percutaneous transluminal angio-plasty (PTA) and exercise training for intermittent claudication have become available since our literature search in September 2010. Mazari and colleagues found that PTA, exercise training, and PTA combined with exercise training were equally effective in improving walking distance and quality of life after 12 months in patients with intermittent claudication due to femoropopliteal disease. The results of the CLaudication: Exercise Versus Endoluminal Revascu-larization (CLEVER) study in patients with intermittent claudication due to aortoiliac disease are clearly outlined in Yan and Kwong's letter.
