Venous Thrombosis III: Interprofessional Care01:29

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...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
Varicose Veins II: Diagnostic Studies and Interprofessional Care01:26

Varicose Veins II: Diagnostic Studies and Interprofessional Care

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Venous Thrombosis IV: Nursing Management

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

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 I: Introduction01:30

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...

Summary

Catheter-based treatments for deep vein thrombosis (DVT) offer benefits for selected patients, potentially preventing post-thrombotic syndrome. Further research is ongoing to establish optimal use of these endovascular DVT therapies.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Cardiology

Background:

  • Deep vein thrombosis (DVT) management has evolved with increased use of aggressive, catheter-based interventions.
  • Endovascular therapies for DVT aim to address risks, benefits, and uncertainties in treatment.

Purpose of the Study:

  • To outline risks, benefits, and uncertainties of endovascular DVT therapies.
  • To describe clinical situations for considering endovascular DVT treatment.
  • To update readers on new outcome data for catheter-based DVT interventions.

Main Methods:

  • Review of risks, benefits, and uncertainties surrounding endovascular DVT therapies.
  • Description of clinical scenarios for endovascular DVT treatment consideration.
  • Analysis of new outcome data for catheter-based DVT interventions.

Main Results:

  • Endovascular thrombolytic therapy is reasonable for selected DVT patients with acute limb-threatening compromise, vena cava occlusion, or iliofemoral DVT.
  • Catheter-based DVT interventions may prevent post-thrombotic syndrome (PTS) in proximal DVT patients.
  • Endovascular intervention can benefit selected PTS patients by reducing venous hypertension and improving limb function.

Conclusions:

  • Endovascular DVT therapies are valuable for specific patient groups, including those with acute limb compromise or proximal DVT.
  • The ongoing ATTRACT Study will evaluate the safety and efficacy of pharmacomechanical catheter-directed thrombolysis (PCDT) for proximal DVT.
  • An individualized approach to patient selection is recommended for interventional DVT therapies pending further study results.
