[Endovascular closure of a foramen ovale after a right pneumonectomy].

We report the case of a patient, 62-year-old, with a non small cell lung cancer treated by right pneumonectomy followed by chemo and radiotherapy. After surgery appeared a refractory hypoxemia increasing with supine position. Cardiac catheterism showed a right left shunt by reopening of the "foramen ovale". We have performed foramen's occlusion by endovascular method with prothetic material with good result until the death, 14 months later, by neoplasic evolution.
