Insights

Fibrin sheaths around central venous catheters can persist after removal, leading to rare but severe cardiac complications in pediatric oncology patients, including valve destruction and atrial erosion.

Area of Science:

  • Cardiology
  • Oncology
  • Medical Devices

Background:

  • Long-term central venous catheters (CVCs) are essential in pediatric oncology.
  • Fibrin sheath formation around CVCs is a common complication.
  • Fibrin sheaths typically resolve after catheter removal without sequelae.

Observation:

  • This report details three pediatric oncology patients.
  • Patients presented with cardiac complications years after CVC removal.
  • Complications involved embolized "ghost" catheters.

Findings:

  • One patient required tricuspid valve replacement due to complete tricuspid valve destruction.
  • Two patients experienced atrial wall erosion.
  • These severe outcomes stemmed from persistent fibrin sheaths and "ghost" catheters.

Implications:

  • Rare but severe complications necessitate long-term follow-up for "ghost" catheters in pediatric oncology.
  • Cardiac monitoring may be warranted in patients with a history of CVC-associated fibrin sheaths.
  • This highlights potential long-term risks associated with CVCs beyond initial treatment.

Cardiac Catheterization II: Right Heart Catheterization

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
