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...

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...

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...

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...
Birth Control Methods01:22

Birth Control Methods

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although vasectomy...

Summary

Postpartum embolization effectively stops severe postpartum bleeding, reducing the need for hysterectomies. This safe interventional radiology procedure also offers a treatment for uterine fibroids, preserving fertility.

Area of Science:

  • Interventional Radiology
  • Obstetrics & Gynecology
  • Vascular Medicine

Context:

  • Postpartum hemorrhage (PPH) is a leading cause of maternal mortality and morbidity.
  • Hysterectomy is often required to control intractable PPH, leading to loss of fertility.
  • Symptomatic uterine fibroids significantly impact women's quality of life, especially those desiring future fertility.

Purpose:

  • To evaluate the efficacy and safety of postpartum embolization in managing severe PPH unresponsive to conventional treatments.
  • To assess the impact of uterine artery embolization on fertility in women treated for PPH.
  • To explore the utility of uterine artery embolization for treating symptomatic uterine fibroids in women who do not desire future pregnancy.

Summary:

  • Postpartum embolization, performed by interventional radiologists upon obstetrician request, provides an effective method to halt severe postpartum bleeding when other measures fail.
  • The procedure demonstrates a favorable safety profile and appears to preserve normal fertility post-embolization.
  • Uterine artery embolization is also a safe and effective treatment for symptomatic uterine fibroids, leading to gradual myoma shrinkage over months.

Impact:

  • Reduces maternal mortality rates associated with postpartum hemorrhage.
  • Minimizes the incidence of postpartum hysterectomies, preserving reproductive potential.
  • Offers a minimally invasive therapeutic option for both acute obstetric emergencies and chronic gynecologic conditions like uterine fibroids.
