BACKGROUND: Although rare, paradoxical embolism sometimes occurs with patent ductus arteriosus (PDA). This study presents a case of PDA-associated paradoxical embolism with acute ischemic stroke (AIS) and pulmonary embolism (PE) following thoracoscopic surgery.
CASE PRESENTATION: A 65-year-old woman developed acute-onset aphasia and right hemiparesis on the third day following thoracoscopic resection for a right lung tumor. Brain magnetic resonance imaging revealed multiple infarcts, and lower extremity venous Doppler ultrasound revealed deep vein thrombosis. The patient subsequently developed dyspnea, tachycardia, and hypoxemia. PE was confirmed by percutaneous transfemoral venous selective pulmonary angiography, which meanwhile demonstrated a PDA lesion. The patient, after receiving catheter-directed thrombolysis and inferior vena cava filter placement, improved in both neurological and respiratory status.
CONCLUSION: For an uncommon but potentially fatal case with PDA-induced paradoxical embolism causing AIS and PE, early recognition and treatment are vital. Further studies are warranted to determine the optimal management and prognosis of patients with PDA-related embolic events.
