Rapid improvements in walking distance and quality of life have been identified in patients with intermittent claudication following percutaneous transluminal angioplasty, but the medium-term results are less well defined. The aim of this study was to assess quality of life and walking distance in the medium term. Walking distance was assessed before percutaneous transluminal angioplasty and at 6 weeks and 1 year after the procedure using a previously validated questionnaire. At the same time, quality of life was assessed using a EuroQol questionnaire and a visual analogue scoring system. Twenty-four patients (12 men, 12 women, mean age 65 years) underwent successful percutaneous transluminal angioplasty (five iliac, 17 femoropopliteal, two both). Significant improvements in walking distance and quality of life were demonstrated following percutaneous transluminal angioplasty. These were maintained at 1 year, although perceived health state deteriorated. During the study period, six patients developed other serious comorbidities. Development of comorbid conditions may affect the medium-term outcome of quality of life studies in patients treated for intermittent claudication. Data from such studies should therefore be interpreted with care.
