Background: Laparoscopic techniques have been used during pregnancy by obstetricians since the 1970's, primarily to diagnose and treat ectopic and heterotopic pregnancies. Pregnancy was considered as an absolute contraindication to laparoscopy by surgeons as recently as 1991, and a few still doubt the safety of minimal access in gravid patients. When an emergent operation is indicated, the surgery should not be withheld on the sole basis of patient's gravid state. On the contrary, the alleviation of maternal disease is thought to take priority because the health of the foetus is dependant on the mother...

Background  The gold standard for antenatal diagnosis of placenta previa is the transvaginal ultrasonography. In placenta previa cases, separation of placental and uterine tissues is challenging even for the most experienced surgeons. Life-threatening obstetrical complications from cesarean deliveries with placenta previa include peripartum hemorrhage, coagulopathy, blood transfusion, peripartum hysterectomy, and multiple organ failure. Cases  We detailed the 3 cases of placenta previa that underwent bilateral uterine artery ligation; if hemostasis was not achieved, horizontal mattress sutures were placed in the lower uterine segment...

Primary extraovarian dysgerminoma is very rare. Nearly all reported uterine germ cell tumors are nondysgerminoma. Herein, we reported a primary intrauterine dysgerminoma. A 21-year-old pregnant woman G2 L1 with a gestational age of 33 weeks referred to an obstetric ward with a chief complaint of labor pain and membrane rupture. Ultrasonography showed a large hypoechoic lobulated area adjacent to the lower part of her uterus. She underwent an operation and a huge mass was detected in her uterus, which was extended to her pelvic floor...

The Republic of Congo is facing a shortage of specialists and an unequal distribution of healthcare professionals between urban and rural areas, limiting access to diagnostic ultrasonography. Besides other issues this project aims at establishing the feasibility of remote training by live teleconsultation in obstetrical ultrasonography, as a mechanism to support isolated care by untrained staff. The project includes abdominal ultrasound testing for women during all stages of pregnancy. The first results have shown that the transmission of dynamic images, at a low cost internet connection, offers the possibility of distance training of peripheral health professionals, with the real-time remote support of gynecologists...

PURPOSE: Although magnetic resonance imaging (MRI) represents the gold standard for image guided adaptive brachytherapy (IGABT) for cervical cancer, the majority of brachytherapy (BT) continues to be guided by computed tomography (CT). However, CT seems to overestimate the target-volume definition, and the potential of transrectal ultrasonography (TRUS) needs further evaluation. This prospective, comparative study aimed to evaluate CT-based target contouring with the incorporation of TRUS during BT...

REVIEW
Tülay Şahin, Onur Balaban
Ultrasonography has gained popularity in recent years among anaesthesiologists and being used widely for regional blocks and central venous catheterization. Ultrasonography for neuraxial blocks was found beneficial especially for determining the correct needle insertion site and estimating the needle insertion depth of epidural space. In many recent studies, ultrasound guided epidural and spinal blocks have been evaluated among obstetric patients. Pre-procedural lumbar ultrasonography and real time ultrasound guidance for neuraxial blocks was the subject of these studies...

BACKGROUND/AIMS: In clinical settings, the pulsatility index (PI) has become a widely used tool for monitoring obstetrics or other vascular diseases. It is based on the maximum Doppler shift waveform derived from ultrasonography. However, it remains unclear whether the PI levels are correctly predicted from the perfusion in mouse model of hindlimb ischemia. METHODS: To explore the relationship between PI and perfusion, we generated a unilateral hindlimb ischemia model in 8-week-old C57BL/6 male mice by ligation of the right common iliac artery and femoral artery...
