Ultrasound I: Abdominal Ultrasonography

387
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Ultrasonography

6.3K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Summary

A multidisciplinary placenta accreta spectrum (PAS) team and standardized ultrasound reduced hysterectomies and length of stay. Improved prenatal diagnosis is needed for better risk stratification.

Area of Science:

  • Obstetrics and Gynecology
  • Maternal-Fetal Medicine
  • Surgical Outcomes

Background:

  • Placenta accreta spectrum (PAS) poses significant risks during delivery.
  • Effective management strategies are crucial for improving maternal outcomes.

Purpose of the Study:

  • To compare outcomes before and after implementing a multidisciplinary PAS team with a standardized ultrasound approach.
  • To evaluate the impact of this integrated approach on hysterectomy rates, blood loss, and length of hospital stay.

Main Methods:

  • Retrospective cohort study of deliveries complicated by PAS (August 2009 - April 2022).
  • Comparison of patient demographics and pregnancy characteristics between pre- and post-PAS team implementation (October 2020).
  • Statistical analysis using Fisher's exact test, chi-squared, t-tests, and Kruskal-Wallis test.

Main Results:

  • The PAS team was associated with a significant reduction in hysterectomies (66% vs. 93%, p < 0.001).
  • Maternal length of stay was significantly shorter with the PAS team (p=0.031 overall, p=0.042 for hysterectomies).
  • Prenatal diagnosis rates increased (97% vs. 83%), with a higher rate of false positives (31% vs. 11%).

Conclusions:

  • A multidisciplinary PAS team combined with standardized ultrasound effectively reduces unnecessary hysterectomies and hospital length of stay.
  • Increased prenatal detection, while beneficial, also leads to a higher incidence of false positive diagnoses.
  • Improved prenatal diagnostic accuracy and preoperative risk stratification are essential for optimizing PAS management.
