BACKGROUND: Various complications can cause hypoxemia after pulmonary resection for lung cancer, but intracardiac shunt that becomes symptomatic and causes severe hypoxemia postoperatively is very rare. We report a case that presented platypnea-orthodeoxia syndrome (POS) due to right-to-left shunt via patent foramen ovale (PFO).
CASE: A 71-year-old man with a lung cancer in the left upper lobe was referred to our hospital. Left upper lobectomy was performed. Dyspnea developed postoperatively, which was worsened by sitting or standing and relieved in a recumbent position. Contrast transesophageal echocardiogram (TEE) and right intracardiac catheterization revealed a right-to-left shunt via PFO. Open-heart closure of PFO was performed and the patient was free from POS.
CONCLUSIONS: Postoperative intracardiac shunt via PFO can cause severe hypoxemia after lung resection. POS suggests the possibility of intracardiac shunt and careful observation is needed.
