Differential Diagnoses
Media Gallery
-
Feet of patient with thromboangiitis obliterans (Buerger disease). Note ischemic ulcers on distal portion of left great, second, and fifth toes. Although patient's right foot is normal in gross appearance, angiography demonstrated compromised arterial flow to both feet.
-
Superficial thrombophlebitis of great toe in patient with thromboangiitis obliterans (Buerger disease).
-
Tobacco smoke stains on male patient's fingers suggest diagnosis of thromboangiitis obliterans (Buerger disease). Patient presented with small, painful ulcers on tips of thumb and ring finger.
-
Lower-extremity arteriogram of peroneal and tibial arteries of patient with thromboangiitis obliterans (Buerger disease) demonstrates classic findings of multiple small and medium-sized arterial occlusions with formation of compensatory "corkscrew collaterals."
