Long-term outcomes of exercise therapy versus revascularization in patients with intermittent claudication.

Shirasu T, Takagi H, Yasuhara J, Kuno T, Kent KC, Farivar BS et al.  

Ann Surg 2023; 278: 172-178.

The analysis included nine RCTs with 1477 patients. After a mean of 3.6 years of follow-up, the rate of development of critical ischaemia was similar: rate ratio 0.77, 95 per cent confidence interval 0.36 to 1.69, P=0.51. Rates of amputation and death were also similar.

Comment: No advantage to life or limb from revascularisation, but may of course benefit symptoms in the shorter term.
