The novel inflammatory marker NLR may be used to predict worse outcomes and hospital mortality in patients with AAD treated by surgical repair.

We aimed to evaluate the characteristics of 198 new patients with Buerger's disease treated surgically in the last decade. We also compared these results with our former series reported in 1993. The records of patients with Buerger's disease who were enrolled in an ongoing investigational protocol between 1991 and 2001 were reviewed. Sympathectomy was carried out in 161 patients and revascularization in 19 patients. The cumulative secondary patency rate was 57.9% for bypass grafts at a mean follow-up of 5.4 years. Clinical outcome following sympathectomy was considered improved in 52.3% of patients, stable in 27.8%, and worse in 19.8%. Seven major and 36 minor amputations were performed, with a limb salvage rate of 95.6%. The aggressiveness of the disease has increased compared with previous series, parallel to the expansion of cigarette consumption. Bypass surgery should be considered for patients with severe ischemia who have target vessels. Sympathectomy still has a role to improve distal flow.
