Core Tip
Core Tip: Veno-venous extracorporeal membrane oxygenation (ECMO) is a vital intervention for severe respiratory failure, but anatomical variations can complicate the procedure. Anatomical variations of the middle hepatic vein, for example, may hinder cannula placement, leading to insufficient flow and severe complications such as liver injury or failure. Real-time ultrasonography and fluoroscopy are essential for detecting and correcting cannula misplacement, ensuring optimal ECMO function, and preventing serious complications. Careful imaging and precise technique are crucial, particularly in patients with anatomical anomalies.
