Tactics of neonatal surgical treatment of uterine appendage torsion in newborns

Introduction. Antenatal torsion of the uterine adnexa remains a challenging diagnostic entity in contemporary perinatal medicine. This is due to the rarity of the condition, the absence of pathognomonic sonographic criteria, and the lack of unified clinical management protocols.
Materials and methods. The presented clinical cases describe rare instances of antenatal torsion of the uterine adnexa in newborns. The key diagnostic findings were obtained through prenatal ultrasound examination, which revealed adnexal mass lesions. The diagnosis was subsequently confirmed intraoperatively and by pathological examination. Both patients underwent laparoscopic surgical treatment with histological verification of ovarian tissue necrosis.
Results. In both cases, patient survival was achieved; however, the adnexal structures involved in the torsion were nonviable due to the development of tissue necrosis.
Conclusion. The presented clinical cases demonstrate the need for further accumulation of experience, systematic data collection, and analysis to establish a consensus-based approach to the diagnosis and management of this condition. Such efforts will not only improve long-term outcomes but also enhance the potential for fertility preservation in affected patients, which is a critical aspect of their future health and reproductive potential. Long-term follow-up and data analysis may form the basis for developing more accurate and effective treatment strategies for antenatal torsion.
