Summary
Cesarean section (CS) scars can heal poorly, increasing risks in future pregnancies. Standardizing ultrasound methods is crucial for assessing scar integrity and predicting complications.
Area of Science:
- Reproductive Medicine
- Obstetrics and Gynecology
- Medical Imaging
Background:
- Incomplete Cesarean section (CS) scar healing is linked to later pregnancy complications like scar pregnancy, placenta accreta, and uterine rupture.
- Current understanding of factors influencing poor CS scar healing and methods for its recognition remains uncertain.
- Existing research lacks consensus on ultrasound terminology, methods, and the clinical significance of CS scar morphology.
Purpose of the Study:
- To review current ultrasound-based definitions and methodologies for describing Cesarean section (CS) scars.
- To evaluate the performance of alternative techniques for assessing CS scar integrity.
- To propose a standardized ultrasound approach for describing CS scars to enable meaningful comparison across studies.
Main Methods:
- Systematic review of existing literature on ultrasound-based descriptions of Cesarean section (CS) scars.
- Analysis of various terminologies, methods, and reported results in ultrasonographic scar assessment.
- Evaluation of data associating scar morphology with the functional integrity of the lower uterine segment.
Main Results:
- Multiple ultrasound techniques exist for describing CS scars, but a lack of standardization hinders consensus on prevalence and clinical significance.
- Limited evidence connects specific ultrasound scar morphologies to the functional integrity of the lower uterine segment.
- There is a growing need for reliable methods to predict complications associated with CS scars.
Conclusions:
- A standardized ultrasound approach is proposed for describing Cesarean section (CS) scars to improve consistency and comparability in research.
- Further research is needed to validate the association between ultrasound scar appearance and actual uterine integrity.
- Developing predictive tests for CS scar complications is increasingly important for maternal health.

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.
