Radiol Clin North Am 2014 Nov 2;52(6):1201-13. Epub 2014 Sep 2.

Department of Radiology and Radiological Sciences, Vanderbilt University Medical Center, 1161 21st Avenue South, CCC-1118 MCN, Nashville, TN 37232-2675, USA; Department of Obstetrics and Gynecology, Vanderbilt University Medical Center, 1161 21st Avenue South, CCC-1118 MCN, Nashville, TN 37232-2675, USA.

Volume imaging in the pelvis has been well demonstrated to be an extremely useful technique, largely based on its ability to reconstruct the coronal plane of the uterus that usually cannot be visualized using traditional 2-dimensional (2D) imaging. As a result, this technique is now a part of the standard pelvic ultrasound protocol in many institutions. A variety of valuable applications of 3D sonography in the pelvis are discussed in this article. Read More

Factors associated with success of vaginal birth after one caesarean section (VBAC) at three teaching hospitals in Addis Ababa, Ethiopia: a case control study.

BMC Pregnancy Childbirth 2013 Feb 1;13:31. Epub 2013 Feb 1.

Department of Obstetrics and genecology, Addis Ababa University, Addis Ababa, Ethiopia.

Background: Vaginal delivery after previous one cesarean section for a non recurring indication has been described by several authors as safe and having a success rate of 60-80%. Hence many centers are offering VBAC for candidates leaving the century old dictum of once cesarean always cesarean. But predicting success of VBAC after trial of labor (TOL) is still a difficult task due to the lack of a validated prediction tool. Read More

Pregnancy complications in women with uterine duplication abnormalities.

Ultrasound Q 2010 Dec;26(4):193-200

Department of Radiology, Beth Israel Deaconess Medical Center, Boston, MA 02215, USA.

Patients with duplication anomalies have a higher incidence of infertility, repeated first trimester spontaneous abortions, fetal intrauterine growth restriction, fetal malposition, preterm labor, and retained placenta. The role of imaging is not only to detect and diagnose müllerian anomalies but also to help distinguish surgically correctable forms of müllerian duct anomalies from nonsurgical forms. Imaging is also important to identify the location of the pregnancy, because ultrasound guidance may be needed after miscarriage or when pregnancies occur in an ectopic location. Read More

Laparoscopically-assisted transabdominal oocyte retrieval in an infertility patient with ovarian malposition.

Reprod Med Biol 2009 Jun 23;8(2):85-87. Epub 2009 Apr 23.

Division of Reproductive Medicine Sugiyama Clinic 1-53-1 Ohara, Setagaya Tokyo Japan.

Infertility patients with malpositioned ovaries have considerable difficulty conceiving naturally because of extended fallopian tubes and ovarian malposition; such patients turn for help to assisted reproductive technology (ART) treatment. For most of these patients, ovarian malposition prevents transvaginal oocyte retrieval, so the transabdominal approach for oocyte retrieval is required. One of our infertility patients presented with ovarian malposition, and laparoscopy-assisted transabdominal oocyte retrieval was performed. Read More

Childs Nerv Syst 2003 Aug 4;19(7-8):555-60. Epub 2003 Jul 4.

Pediatric Radiology Department, Hôpital Necker-Enfants Malades, 149 rue de Sevres, 75743 Paris Cedex 15, France.

Introduction: Diastematomyelia, also termed split cord malformation, is a form of occult spinal dysraphism characterized by a cleft in the spinal cord. Prenatal diagnosis of this anomaly is possible by ultrasonography (US), and fetal MRI can be used to diagnose the type of diastematomyelia precisely. Diastematomyelia can be isolated or associated with other dysraphisms, segmental anomalies of the vertebral bodies, or visceral malformations (horseshoe or ectopic kidney, utero-ovarian malformation, and anorectal malformation).
