RationaleVascular complications associated with extracorporeal membrane oxygenation (ECMO) increase the in-hospital mortality. Perforation of the inferior vena cava (IVC) during venovenous extracorporeal membrane oxygenation (V-V ECMO) cannulation and subsequent emergency management prior to vascular surgery has rarely been reported.Patient ConcernsA 72-year-old female was diagnosed with IVC perforation caused by venovenous extracorporeal membrane oxygenation cannulation.DiagnosesAbdominal computed tomography venography with 3D reconstruction confirmed that the cannula tip had perforated the abdominal cavity from the conjunction of the iliac vein and IVC. As a result, the patient was diagnosed with inferior vena cava perforation.InterventionsAttempts to reposition the dislocated cannula using digital subtraction angiography were unsuccessful. However, we found that ECMO could maintain a stable blood flow; therefore, we decided to keep ECMO running, and to minimize blood loss from the puncture site, we ensured adequate blood transfusion while operating V-V ECMO. Subsequently, emergency laparotomy was performed to fix the vascular lesion, and we established a new V-V ECMO circuit through cannulation of the bilateral internal jugular veins.OutcomesIn the case of confirmed V-V ECMO-related vascular perforation of the IVC, it is crucial to continue ECMO device operation to maintain negative pressure in the IVC and position the dislocated catheter to block the perforation site, effectively controlling bleeding. Therefore, emergency laparotomy should be promptly performed for vascular repair. Fortunately, the patient recovered successfully and was subsequently discharged.LessonsThis case highlights several important lessons: When advancing a cannula, in this case, it is essential to first identify the guidewire placement to ensure proper guidance; In the event of a confirmed V-V ECMO-related vascular perforation of the IVC, maintaining negative pressure in the IVC through continued ECMO device operation and positioning the dislocated catheter to block the perforation site are crucial steps to control bleeding prior to emergency open vascular repair; After undergoing vascular repair, if ECMO support is still necessary, it is advisable to opt for a catheterization strategy that avoids previously repaired blood vessels.Copyright © 2023 the Author(s).
