BACKGROUND: Revascularization is the optimal treatment for critical limb ischemia (CLI). Traditional measures of outcome of intervention are as follows: graft patency, limb salvage rates, and patient survival rates; however, these have little meaning for a patient if he/she cannot ambulate independently or go back to work. This study was undertaken to assess the functional outcome of intervention in these patients. METHODS: Fifty patients with CLI treated over a 3-year period were included in this prospective clinical study. After evaluation, treatment was given to each patient on the basis of the Transatlantic Inter-society Consensus II guidelines. The outcome of treatment and the functional restoration to pre-illness lifestyle were assessed at the end of 1 month, and then at 6 months. RESULTS: Fifty patients with CLI were included in the study; male to female ratio was 9:1, and the mean age at presentation was 45 years. After evaluation, only 38 patients (76%) were found suitable for revascularization. Traditional measures of success showed a graft patency rate of 75%, limb salvage rate of 89.5%, and patient survival rate of 96% at 6 months after treatment. All eight parameters of quality-of-life analysis showed significant improvement as assessed by the Research and Development (RAND) 36-Item Health Survey 1.0 form. However, among the 38 patients who were revascularized, 20 (52.6%) went back to their initial occupation after 6 months, 12 (31.6%) remained at home even though they were ambulant, and five (13.2%) were able to manage only limited activities; one patient succumbed to death. CONCLUSION: With only 53% of revascularized patients returning to work, a salvaged leg does not equate with return to premorbid ambulatory/occupational status, although there might be improvement in quality of life because of other reasons. As surgeons, we need to look beyond leg salvage and graft patency and take on a more holistic approach.
