Placental insufficiency and maternal death caused by advanced stage of breast cancer in third trimester.

We describe a case with placental, and general metastases, resulting in transient intrauterine and general hypoxia, and with additionally clinical features similar to HELLP syndrome. A patient in the third trimester with dyspnea at rest developed right heart failure during c-section. During emergency thoracotomy the patient went into generalized shock and died after intense CPR. Placental insufficiency was based on a multilocal metastatic event, decreasing the utero-placental perfusion.
