A Formation of a true knot in subclavian venous catheter in a patient in the intensive care unit

Abstract

Vascular catheters installation is most frequently used in critical care units. A node in the catheter lumen is a rare mechanical complication of the central venous catheterization. The 14-year-old was treated for acute appendicitis complicated by diffuse purulent peritonitis. It was decided to install a central venous catheter on the very first day of treatment. A catheterization of the right subclavian vein according to Seldinger was carried out. The catheter functioned properly for 6 days. On the 7th day, in the process of removal of the catheter, its extraction was blocked at a 1 cm depth from the tip. The catheter was removed by strong physical force with the occurrence of a hematoma in the area of installation of the catheter. Once removed, on the catheter there was found a node, formed inside the vessel. In this case, no disabling and life-threatening complications as a result of the use of the catheter were recorded. In the future, the patient was discharged recovered.
