AI Article Synopsis
- The study aimed to define new ultrasound parameters for assessing cesarean scars and analyze how these vary with the number of cesarean deliveries.
- Transvaginal ultrasound was performed on 109 women, revealing that 100% had detectable cesarean scars, with differences noted in scar thickness and index values among those with multiple cesarean sections.
- The findings indicated a significant decline in scar thickness and certain index values for women who had three cesarean sections compared to those who had one or two, highlighting the impact of multiple surgeries on scar quality.
Article Abstract
Objectives: To define and assess the new ultrasonographic parameters of cesarean hysterotomy scars and to analyze their variation depending on the number of cesarean sections.
Material And Methods: Transvaginal ultrasound was carried out among 109 patients after cesarean section in the lower uterine segment with single-layer uterine closure. The following cesarean hysterectomy scar parameters were assessed: angle of the apex (K), basis (P) and height (W) of the anechoic triangle, the thickness of the knit tissue scar segment (G), G/P index and G/W index.
Results: Transvaginal ultrasound detected the cesarean hysterectomy scar in 100% of the examined woman. In 5.5% of cases the completely knit hysterectomy scar tissue was identified. All patients from this group underwent a single cesarean section. In the remaining 94.5% of women, the ultrasound detected a presence of the anechoic triangle, defined as scar defect. No difference of statistical importance considering assessed scar parameters was observed between the groups of patients after one and two cesarean sections. The decrease of the thickness of the knit tissue scar segment (G) in the group of patients after three cesarean, sections in comparison to the group of patients after single (1.3 mm vs. 6.7 mm, p = 0.0134) and two (1.3 mm vs. 7.4 mm, p = 0.0366) abdominal deliveries, was found, as well as statistically important decrease in G/P index value in the group of patients after three cesarean sections in comparison to the patients after one (0.3 vs. 1.3, p = 0.0263) and two cesarean sections (0.3 vs. 1.2, p = 0.0138).
Conclusions: The new ultrasonographic parameters to assess the cesarean hysterectomy scar in nonpregnant uterus were introduced. Statistically important decrease in the thickness of the knit tissue scar segment (G) and G/P index value in the group of patients after three cesarean sections in comparison to the group of patients after single and two abdominal deliveries was revealed.
