Insights

A giant thrombus adhered to an intravenous hyperalimentation (IVH) catheter in the right atrium. Histopathology confirmed thrombus, highlighting its potential as an intra-cardiac mass cause.

Area of Science:

  • Cardiology
  • Vascular Surgery
  • Oncology

Background:

  • Intravenous hyperalimentation (IVH) catheters are used for nutritional support in patients with advanced gastric cancer.
  • Intra-cardiac masses can be challenging to diagnose and manage, especially when associated with indwelling devices.

Observation:

  • A 63-year-old male with advanced gastric cancer developed a large (22 x 20 mm) intra-right atrial mass.
  • Echocardiography revealed a low-echo density mass adhered to an IVH catheter within the right atrium.
  • Transesophageal echocardiography confirmed the IVH catheter pierced the mass, but differentiation between vegetation and thrombus was difficult.

Findings:

  • Surgical removal of the intra-cardiac mass was performed.
  • Histopathological examination definitively diagnosed the mass as a giant thrombus.
  • The thrombus was found to be adhered to the indwelling IVH catheter.

Implications:

  • This case underscores the importance of considering thrombus formation as a potential cause of intra-cardiac masses in patients with indwelling IVH catheters.
  • Early detection and management are crucial to prevent complications associated with intra-atrial thrombi.
  • Further research may explore preventative strategies for thrombus formation around central venous catheters.

Cardiac Catheterization I: Pre-Procedure Overview01:28

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...

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 III: Left Heart Catheterization

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
