A rare case of ovarian cancer in pregnancy complicated by pulmonary embolus and myocardial infarction: management dilemmas

Malignant ovarian neoplasms diagnosed during pregnancy at advanced stages are very rare. The clinical course and prognosis of pregnant patients diagnosed with epithelial ovarian cancer is similar to that of non-pregnant patients. We describe our management of a woman diagnosed with FIGO IIIc ovarian cancer at Caesarean section. Immediately after surgery she suffered a pulmonary embolus and a myocardial infarction. She showed signs of a severe pulmonary hypertension (59 mmHg). Four weeks later the pulmonary hypertension was still moderate but, despite her critical status, she underwent primary debulking surgery (PDS). This was performed under extensive anaesthesiological monitoring. Through this rare case, we show that despite the complex initial status of a critically ill patient, PDS can still remain the mainstay of treatment in patients with advanced ovarian cancer as most patients are able to tolerate even extensive debulking surgery without the need for neoadjuvant chemotherapy.
