Ovarian torsion refers to the rotation of the ovary at its pedicle, to such a degree as to occlude the ovarian blood supply or drainage, which can potentially damage the ovary. Patients with ovarian torsion often present with sudden onset of sharp and usually unilateral lower abdominal pain, accompanied by nausea and vomiting.
Ovarian torsion is a medical emergency and requires immediate treatment. It is typically diagnosed through a physical exam and imaging tests such as an ultrasound. Treatment may include surgery to untwist the ovary and restore its blood supply. In some cases, the ovary may need to be removed if it has been damaged due to ischemia.
