Supervised exercise training is not associated with increased gastrocnemius muscle oxygenation during exercise or increased hyperemic hemoglobin flow after a model of ischemia. This suggests that the symptomatic improvement witnessed is not the result of increased oxygen delivery to the active muscle. The enhanced recovery after exercise training therefore reflects a combination of enhanced metabolic economy and increased oxidative capacity, suggesting that exercise training helps reverse an acquired metabolic myopathy.

UGFS with CO₂/O₂ instead of air was associated with a slightly increased saphenous truncal occlusion rate and reduced the incidence of skin staining without increasing thrombophlebitis in this clinical series. We observed only one transient neurological event in this series so could not evaluate the effect of CO₂/O₂ foam in reducing these events.

Supervised exercise training for claudication results in an increase in the proportion of MHC type I expression within the symptomatic gastrocnemius muscle.

The Vascular Society of Great Britain and Ireland recognises the importance of interventional vascular radiology as part of the multidisciplinary approach to the provision of emergency vascular services. However, arranging emergency rotas for vascular radiology is not easy because of the small numbers of interventional radiologists who may also be required to cover other specialities.
