Summary
Inferior vena cava filter embolization is uncommon, but fracture can lead to heart migration. A young woman required open cardiac surgery to remove a fractured filter, preventing further complications.
Area of Science:
- Cardiovascular Surgery
- Medical Device Technology
- Interventional Radiology
Background:
- Inferior vena cava (IVC) filter embolization occurs in up to 11.8% of cases.
- Device migration to the heart is a rare but serious complication, often associated with IVC filter fracture.
Observation:
- A young woman presented with hemodynamic instability three days post-routine IVC filter placement.
- The IVC filter had fractured, and the device had migrated, posing an immediate risk.
Findings:
- The fractured IVC filter was not retrievable via standard endovascular methods.
- Open cardiac surgery under cardiopulmonary bypass was necessary for successful device removal.
Implications:
- This case highlights the potential for catastrophic complications from IVC filter fracture and migration.
- Surgical intervention may be required for retrieval when endovascular methods fail, emphasizing the need for careful monitoring and timely intervention.

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...

01:25Hemodialysis I: Introduction
313
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

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...

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...
