Three‐dimensional ultrasonography in power Doppler mode (3D power Doppler) allows the appropriate quantitative assessment of the ovarian tissue vascularization. The present case is of an ovarian torsion in a pregnant woman at 6.5 weeks with ovarian hyperstimulation syndrome due to in vitro fertilization. Gray‐scale images of endovaginal two‐dimensional ultrasonography revealed enlargement of the right ovary and multiple peripheral follicles. Two‐dimensional ultrasonography in color Doppler mode… Expand
Case report: ovarian torsion in pregnancy - diagnosis and management.
A high clinical suspicion and early laparoscopic management correlate with favorable maternal and fetal outcomes, and the mere presence of blood flow on Doppler ultrasonography of the adnexa has a poor negative predictive value. Expand
3D/4D sonographic evaluation of amniotic band syndrome in early pregnancy: A supplement to 2D ultrasound
3D/4D ultrasound has the potential to be a supplement to conventional 2D ultrasound in evaluating amniotic band syndrome and could readily understand the fetal conditions and undergo counseling and choose the option of termination of pregnancy. Expand
Myths in the Evaluation and Management of Ovarian Torsion.
Although ovarian torsion is a challenging diagnosis, understanding myths surrounding the disorder may help emergency physicians consider it in unusual populations and improve emergency diagnosis and evaluation. Expand
Laparoscopic management of adnexal torsion
It is proved that timely diagnosis and intervention could help the ovarian salvage in women of reproductive age group and the outcome of minimally invasive laproscopic surgery in the management of adnexal masses was excellent. Expand

Conservative Management of Theca Lutein Cyst Accident: A Case Report
Theca lutein cysts can occur in 20-25% of molar pregnancies and in order to prevent recurrence adnexal fixation can be undertaken by plicating the ovarian ligament. Expand
Adnexal torsion in children: The role of family practice physicians and paediatricians
Paediatricians and general practitioners should perform early ultrasound and Doppler and refer patients to tertiary care centres where early intervention could save the patients' ovaries and future fertility, according to a retrospective study carried out in children ≤18 years old. Expand

3D power Doppler characteristics of unilateral ovarian torsion 2 weeks after embryo transfer in a pregnant patient with bilateral hyperstimulated ovaries is described. Expand
Usefulness of Doppler sonography in the diagnosis of ovarian torsion.
Abnormal flow detected by Doppler sonography is highly predictive of adnexal torsion and is therefore useful in the diagnosis of ovarian torsions, however, when normal flow is detected, it does not necessarily exclude an ovulation induction case and time to diagnosis in these cases is delayed.

Diagnosis of ovarian torsion with color Doppler sonography: depiction of twisted vascular pedicle.
Identification of the twisted vascular pedicle through ultrasonography is suggestive of ovarian torsion, and color Doppler sonography could be helpful in predicting the viability of adnexal structures by depicting blood flow within the twistedascular pedicle. Expand
Color Doppler sonography of adnexal torsion.
The color Doppler sonographic features in 13 patients with surgically proved adnexal torsion that help determine whether or not the ovaries were viable or nonviable at the time of surgery are presented. Expand
Sonographic evaluation of ovarian torsion in childhood and adolescence.
Emergency sonographic examination of the pelvis was performed in 41 girls with clinical suspicion of ovarian torsion and a 100% sonographic sensitivity for space-occupying disease of the ovary was obtained with a positive predictive value of 88% for the diagnosis of ovarianTorsion. Expand
Torsion of a hyperstimulated ovary during pregnancy: a potentially difficult diagnosis
Two cases of torsed hyperstimulated ovaries where grey scale and Doppler sonographic evaluation were inconclusive are presented and it is emphasized that MRI and physical exam skills are useful adjuncts to ultrasound in the evaluation of a pregnant patient. Expand

A positive whirlpool sign in the twisted vascular pedicle of the ovary is the most definitive sign of ovarian torsion and is predictive of nonviability of the Ovary. Expand
Adnexal torsion of hyperstimulated ovaries in pregnancies after gonadotropin therapy.
It is concluded that torsion of hyperstimulated adnexa in patients who conceived after gonadotropin therapy, is a special entity that requires more attention to achieve early diagnosis and can be saved by simply unwinding it. Expand
Ovarian torsion: clinical and imaging presentation in children.
A high level of clinical suspicion, expeditious imaging, and familiarity with the varied clinical and imaging presentations of ovarian torsion should decrease the surgical delay and improve the likelihood of ovarian salvage. Expand
