Abstract

Acute abdomen in pregnancy is one of the biggest diagnostic and therapeutic challenges today. Despite advances in medical technology, the preoperative diagnosis of acute abdominal conditions is still inaccurate. Torsion of the adnexa, which refers to complete or partial rotation of the adnexa, resulting in obstruction of venous and lymphatic reflux in the ovary, is a common gynecological emergency. Torn adnexa affect both the ovary and the fallopian tube, and rarely affect only one of them. Adnexal torsion occurs more frequently in the first and early second trimester than in the third trimester. It is difficult to diagnose in advanced pregnancy because of nonspecific symptoms and signs of acute abdomen as well as ultrasound limitations due to uterine enlargement complicate diagnosis. Late diagnosis and delayed surgical treatment result in ovarian loss and fetal endangerment. It is important to thoroughly evaluate the adnexa at the 1st ultrasound examination in pregnancy and to monitor the observed formations.
