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 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 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 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...
Pulmonary Embolism I: Introduction01:29

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 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...

Summary
This summary is machine-generated.

Venous thromboembolism is a major cause of maternal death. Diagnosis of deep venous thrombosis and pulmonary embolism during pregnancy requires specific imaging, with low-molecular-weight heparin being the preferred treatment.

Point-Of-Care Ultrasound Screening for Proximal Lower Extremity Deep Venous Thrombosis

Published on: February 10, 2023

Area of Science:

  • Obstetrics and Gynecology
  • Hematology
  • Vascular Medicine

Background:

  • Venous thromboembolism (VTE) is the leading cause of maternal mortality in the United States.
  • Pregnancy significantly increases the risk of deep venous thrombosis (DVT), especially with a history of thrombosis or thrombophilia.
  • While general screening for thrombophilia is not advised, testing is recommended for high-risk individuals.

Purpose of the Study:

  • To review the risk factors, diagnostic methods, and management strategies for venous thromboembolism in pregnancy.
  • To highlight the importance of early and accurate diagnosis of DVT and pulmonary embolism (PE) in pregnant patients.
  • To discuss the safety and efficacy of anticoagulation therapies during pregnancy and postpartum.

Main Methods:

  • Review of current literature on VTE in pregnancy.
  • Discussion of diagnostic modalities including Doppler ultrasonography for DVT and CT scans for PE.
  • Analysis of anticoagulation options, including heparinoids and warfarin, in the context of pregnancy and breastfeeding.

Main Results:

  • Factor V Leiden and prothrombin G20210A mutations are common inherited thrombophilias; antiphospholipid antibody syndrome is a key acquired defect.
  • Clinical DVT symptoms can be subtle and mimic gestational edema, necessitating diagnostic imaging.
  • Pulmonary embolism often presents postpartum with respiratory symptoms, requiring prompt CT evaluation.

Conclusions:

  • Accurate diagnosis of VTE in pregnancy relies on appropriate imaging techniques.
  • Low-molecular-weight heparin is the preferred anticoagulant for prophylaxis and treatment during pregnancy.
  • Warfarin is safe postpartum and compatible with breastfeeding, while contraindicated during gestation.
