Pulmonary arterial dissection is an uncommon but usually a deadly complication of chronic pulmonary hypertension. However, with the development of diagnostic and therapeutic interventions in recent years, a few reports in surviving patients with pulmonary artery dissection have been reported.

Patent ductus arteriosus (PDA) is a congenital anomaly caused by a failure to close of a fetal vessel which connects the pulmonary artery directly to the ascending aorta after birth. A rare but lethal complication of PDA is pulmonary artery dissection and dissection usually occurs as a result of chronic pulmonary arterial hypertension associated with PDA and is typically seen in patients with Eisenmenger’s syndrome[2-5]. In this report, we described pulmonary artery dissection in a pregnant patient with a previously un-diagnosed PDA without an obvious rise in pulmonary artery pressure.

Case Report:
A 26-year-old female patient was admitted to our clinics with sudden dyspnea and chest discomfort one hour after giving birth to twins by vaginal delivery. She had no previous medical history. On physical examination, her blood pressure was 100/60 mmHg and pulse rate was 125/min. The ECG was consistent with sinus tachycardia. An echocardiography was performed with a pre-diagnosis of pulmonary embolism. However, echocardiographic examination revealed a dilated main pulmonary artery and a dissection flap extending from main pulmonary artery to left pulmonary artery....
