Introduction: The problem of tumors and tumor-like formations of the ovaries in pregnant women today remains relevant due to the lack of standardized methods for their diagnosis and treatment tactics in pregnant women.

Aim: This thesis were to evaluate the effectiveness of management of pregnant women with tumors and tumor-like formations of the ovaries to determine the prognosis of pregnancy and the condition of the fetus.

Material and methods: In a retrospective registry study, including women who delivered during a three-year period, there were 12 pregnant women with detected tumors and tumor-like formations of the ovaries during pregnancy. Confirmation of the diagnosis was performed by ultrasound examination with Doppler blood flow in these tumors. The average age of pregnant women was 25, 2 years. During the first screening examination, ovarian pathology was detected in 10 pregnant women (83.3%), in 2 pregnant women during the second screening examination (16.7%). Surgical treatment required 4 patients (33.3%), which was performed by laparoscopic access at 16-17 weeks of pregnancy. Indications for surgical treatment were – torsion of the leg of the cyst in 3 pregnant women and 1 pregnant woman with severe pain in combination with large tumors. All other pregnant women were observed conservatively under dynamic supervision.  The score of all newborns for Apgar was 8-9 points

Results and conclusions: Ultrasound examination with Doppler vascular tumors and ovarian tumors can confirm the diagnosis, choose the optimal method of surgical treatment in case of complications associated with these formations; the optimal time for laparoscopic treatment is 16-17 weeks of pregnancy.
