Insights

Endovascular catheter thrombectomies effectively removed inferior vena cava (IVC) and iliac vein thromboses, preventing embolism and restoring blood flow. Long-term IVC patency was achieved in over 83% of patients.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Cardiovascular Medicine

Background:

  • Floating thromboses in the inferior vena cava (IVC) pose a significant risk of pulmonary thromboembolism (PTE).
  • Effective treatment strategies are crucial for managing these thromboses and preventing embolic events.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of endovascular catheter thrombectomies (ECT) for "high" floating thromboses of the IVC.
  • To establish an algorithm for using ECT in preventing PTE and treating IVC thromboses.

Main Methods:

  • Seventy-two patients with "high" floating IVC thromboses underwent ECT.
  • Assessment of complete and partial thrombus evacuation, complication rates, and IVC patency post-procedure.

Main Results:

  • Complete thrombus evacuation was achieved in 48 patients from the IVC and 4 from common iliac veins.
  • IVC patency was maintained in 92.9% at the hospital stage and 83.3% long-term.
  • ECT eliminated the source of embolism and facilitated optimal cava filter placement.

Conclusions:

  • ECT is an effective method for treating floating IVC thromboses, resolving embolic source and restoring venous patency.
  • Developed an algorithm for ECT application based on patient condition, thrombosis characteristics, and risk factors.
  • High rates of IVC patency support the role of ECT in preventing PTE.

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

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...

Pulmonary Embolism III: Nursing Management

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
Pulmonary Embolism I: Introduction01:19

Pulmonary Embolism I: Introduction

A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
