An Iatrogenic Complication of Radial Artery Cannulation

摘要

Here, we report a potentially serious iatrogenic complication of arterial cannulation, and discuss the management and prevention of accidental arterial cannula transection. A 73-year-old man suffered from accidental cannula transection after removal of a radial arterial cannula. Three-dimensional computed tomography was used to confirm and locate the retained catheter. Surgical exploration was performed to remove the retained catheter, and the operation was completed smoothly without residual sequelae. Iatrogenic transection of arterial cannula is rarely reported. However, we should always be aware of the possibility of occurrence of this severe complication. We provide some recommendations for its management and ways to prevent its occurrence.
