Review Comparative Study
[Buerger's disease or thromboangiitis obliterans].
To review clinical data, pathophysiology and treatment of thromboangiitis (Buerger's disease). ⋯ If pathophysiology is still poorly understood, spontaneous evolution can be avoided by stopping tobacco and prostacyclin.

A right-to-left shunting across a patent foramen ovale is a rare cause of acute respiratory failure after pneumonectomy. ⋯ A platypnea-orthodeoxia (dyspnea induced by the upright position with arterial deoxygenation relieved by recumbency) should lead to the diagnosis which is confirmed by echography or cardiac catheterization. The prognosis is good after surgical closure of the patent foramen ovale. The physiopathologic mechanism is poorly understood. We report two cases of platypnea-orthodeoxia.
