Venous Thrombosis III: Interprofessional Care

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...

In Vitro Fertilization

In Vitro Fertilization

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Hemodialysis I: Introduction

Hemodialysis I: Introduction

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...

Veins of the Abdomen and Pelvis

Veins of the Abdomen and Pelvis

The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

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...

Summary

Inferior vena cava (IVC) filters appear safe for use during pregnancy, with no identified complications for mothers or babies. This study found no adverse outcomes in pregnancies with IVC filters in situ.

Area of Science:

Obstetrics and Gynecology
Vascular Surgery
Maternal Health

Background:

Thromboembolism is a leading cause of maternal mortality in the UK.
Inferior vena cava (IVC) filters are used for recurrent thromboembolism or when anticoagulation is contraindicated.
The safety of IVC filter use during pregnancy is not well-established due to limited data.

Purpose of the Study:

To review pregnancy outcomes in women who required an IVC filter during pregnancy.
To assess the safety and complications associated with IVC filter placement or continuation during gestation.

Main Methods:

Retrospective review of obstetric and radiology databases.
Identification of 12 pregnancies in 6 women with an IVC filter in situ.
Analysis of antenatal, delivery, and neonatal outcomes.

Main Results:

No antenatal complications were observed related to IVC filter placement.
No recurrent thromboembolism occurred in pregnancies with pre-existing filters.
All infants were born in good condition with normal Apgar scores and mean birthweight of 2982 g.

Conclusions:

IVC filter placement or continuation during pregnancy did not appear to cause adverse maternal or fetal outcomes in this case series.
Further research may be warranted to confirm safety in larger cohorts.
Obstetric indications guided delivery mode in all cases.
