Accidental portal vein catheterization during pleural drainage catheter insertion: a case report

Abstract

Abstract Background Iatrogenic portal vein (PV) injuries following pleural drainage catheter (PDC) insertion are rare but life-threatening. This case report emphasizes the importance of prompt recognition and effective interventional radiology (IR) management. Case presentation A 38-year-old Asian male, admitted for a non-ST-segment elevation myocardial infarction, suffered a critical PV injury during PDC insertion, leading to rapid clinical deterioration. The IR team conducted a portogram, retrieved the catheter, and successfully executed an embolization procedure. The patient's recovery, confirmed through imaging and improving liver function tests, enabled discharge with follow-up instructions. Conclusions This case highlights the clinical significance of promptly recognizing and effectively managing iatrogenic PV injuries during PDC insertion, with the pivotal role of IR. Collaboration between IR and surgical teams is crucial for optimizing patient outcomes.
