RESUMEN
We report a case of a 22-year-old female with antiphospholipid antibody (APLA) syndrome who presented with severe dyspnea. Diagnostic imaging confirmed pulmonary embolism (PE), and treatment comprised unfractionated heparin and apixaban. APLA syndrome was diagnosed based on clinical, serological, and radiological findings. During evaluation, the patient developed cardiogenic shock necessitating catheter-directed thrombolysis, followed by veno-arterial extracorporeal membrane oxygenation (VA-ECMO) due to deteriorating condition and suspected heparin-induced thrombocytopenia (HIT). Surgical embolectomy with bivalirudin use followed, and a hybrid veno-arterial-venous (VAV) ECMO setup was implemented. Postoperatively, the patient improved, transitioning to veno-venous (VV) ECMO and eventually ECMO withdrawal. ECMO is a valuable tool for managing complex cardiorespiratory cases like PE. In the context of HIT and APLA syndrome, prompt anticoagulant transition is vital, and bivalirudin is an effective heparin alternative. Our study highlights the challenges involved in managing patients needing ECMO support with immunothrombotic conditions like HIT and APLA syndrome.
