Patent muscular vessels in atheromatous obstruction of tibial arteries: a support of more peripheral revascularization procedures?
A considerable number of patients having aorto-femoral surgery for chronic obliterative atherosclerosis show evidence of obstructed run-off vessels. In this condition poorer long-term results were documented in many series. The present study was aimed at investigating the state of 33 small muscular arteries of 8 limbs amputated for atherosclerotic gangrene. Histological studies showed that 11 muscular arteries were completely free from atheromatous lesions and that another 11 with minor abnormal features could be considered susceptible of revascularization. The conclusive data from this study in a small series suggest that in generalized atherosclerotic obstruction of lower limbs, nearly 70 per cent of the muscular vessels distal to the obstruction are potentially suitable for revascularization.
