Buerger disease is a rare peripheral vascular disease that most frequently affects young men and is strongly correlated with tobacco use. Although several options have been suggested, no consensus exists on the management of patients with Buerger disease except for smoking cessation. Revascularization is sometimes required to salvage ischemic limbs; however, it is often not feasible because of a lack of distal target vessels. Herein, we present the cases of three patients with tissue loss and gangrene due to Buerger disease. These patients underwent dorsal metatarsal artery bypass and avoided amputation.
