Area of Science:

  • Vascular Medicine
  • Oncology Support Care

Background:

  • Indwelling central catheters are increasingly used for chemotherapy, blood products, and parenteral nutrition.
  • Catheter-related thrombosis is a significant complication, involving fibrin sleeve formation or vessel wall thrombus.
  • While often asymptomatic, thrombosis can lead to severe outcomes such as catheter occlusion, vascular obstruction, septic phlebitis, and pulmonary embolism.

Purpose of the Study:

  • To discuss the pathophysiology of central venous catheter thrombosis.
  • To outline the management strategies for catheter-related thrombosis.

Main Methods:

  • Review of existing literature on catheter thrombosis.
  • Analysis of clinical manifestations and complications.
  • Discussion of diagnostic and therapeutic approaches.

Main Results:

  • Catheter thrombosis presents as fibrin sleeves or mural thrombi.
  • Potential complications include catheter dysfunction and thromboembolic events.
  • Pathophysiology involves endothelial injury and stagnant blood flow.

Conclusions:

  • Catheter thrombosis is a frequent and potentially serious complication of central venous catheter use.
  • Effective management requires understanding the underlying pathophysiology and prompt intervention.
  • Further research may improve prevention and treatment strategies.
