Adnexal TorsionAdnexal torsion is the twisting of part or all of the adnexa on its mesentery. It usually involves the ovary but may also involve the fallopian tube.
Torsion accounts for 2–3% of gynecological emergencies and usually occurs in the reproductive age group (including during pregnancy), but is not uncommon before menarche or in postmenopausal women. It occurs because of the mobility of the supporting pedicles, infundibulopelvic, and ovarian ligaments. During torsion, venous blood flow followed by arterial flow is impaired. This leads to congestion, adnexal edema, ischemia, and necrosis.
Torsion of a normal-sized ovary or of an ovary with cysts smaller than 5 cm is rare. Risk factors include the presence of large and heavy ovarian cysts, such as benign cystic teratoma (dermoid cyst), and tubal pathology including hematosalpinx, hydrosalpinx, and para-ovarian cysts.
