Summary

Central venous catheter occlusion, often caused by thrombus formation, is a common issue. This case highlights retrograde flow within a sleeve thrombus as a cause of pain, suggesting anticoagulant use to prevent thrombosis.

Area of Science:

  • Vascular Surgery
  • Thrombosis Research

Background:

  • Central venous catheter (CVC) occlusion is frequently caused by thrombus formation, leading to catheter malfunction.
  • The precise pathology and pathogenesis of CVC-related thrombosis are often unclear due to inconsistent terminology in medical literature.
  • This review aims to clarify the pathogenesis and symptoms of CVC-related thrombosis and propose treatment strategies.

Observation:

  • A case report details a patient with a percutaneously placed left subclavian central venous line.
  • After nine months, the patient experienced significant pain during port injection, localized over the catheter tubing.
  • Surgical examination revealed retrograde flow around the catheter within a sleeve thrombus as the cause of pain.

Findings:

  • Central venous catheter-related thrombosis can manifest with localized pain during catheter use.
  • Sleeve thrombus formation with retrograde flow is a specific mechanism causing CVC malfunction and pain.
  • The case underscores the importance of understanding the varied presentations of CVC thrombosis.

Implications:

  • Minimizing the risk of thrombus formation is crucial for patients with long-term indwelling central venous catheters.
  • Prophylactic anticoagulant therapy should be considered to prevent central venous catheter-related thrombosis.
  • Standardizing terminology and understanding specific thrombotic mechanisms can improve CVC management and patient outcomes.
