Metroplasty and fetal survival.

Area of Science:

• Reproductive Medicine
• Surgical Gynecology
• Maternal-Fetal Medicine

Background:

• Uterine malformations, particularly symmetric types, are associated with infertility and recurrent pregnancy loss.
• Habitual abortions and preterm births significantly reduce fetal survival rates in affected women.

Purpose of the Study:

• To evaluate the efficacy of metroplasty in improving fetal survival rates for women with symmetric uterine malformations.
• To assess the outcomes of pregnancies following metroplasty in patients with a history of habitual abortions and/or preterm births.

Main Methods:

• A retrospective analysis of 20 cases of metroplasty for symmetric uterine malformations performed between 1973-83.
• Surgical techniques included modified Jones & Jones (16 cases), Tompkins (3 cases), and Strassman (1 case).
• Pregnancy outcomes before and after metroplasty were compared, focusing on fetal survival rates.

Main Results:

• Preoperative fetal survival rate was 6.5% (2 live births from 46 pregnancies).
• Postoperative fetal survival rate increased to 86.4% (19 live births from 22 pregnancies).
• No operative complications were noted; subsequent pregnancies had few complications, with most deliveries via Cesarean section.

Conclusions:

• Metroplasty is a highly effective surgical intervention for improving fetal survival in women with symmetric uterine malformations and a history of pregnancy loss.
• The procedure significantly enhances the likelihood of successful term pregnancies without increasing risks in subsequent gestations.
