Obstetric ultrasonography, or prenatal ultrasound, is the use of medical ultrasonography in pregnancy, in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus (womb).
The first two percutaneous ultrasound-guided fetal balloon valvuloplasties, a type of fetal surgery for severe aortic valve obstruction in the heart, were reported in 1991. [13] Among the first dozen reported attempts at this repair in the 1990s, only two children survived long-term.
Use of ultrasound to measure the size of the fetus in the womb is controversial, as these methods are often inaccurate and may lead to unnecessary caesarian section; a trial of labour is often recommended even if size of the fetus is estimated to be large. [2] Theoretically, pelvimetry may identify cephalo-pelvic disproportion. However, a woman ...
An ultrasound is performed before the procedure to view the position of the fetus and may be used during the procedure to help guide the needle. The mother’s blood is drawn for comparison against fetal blood, and intravenous access is established in the mother in order to supply medications as needed.
His manual dexterity at procedures and the Rodeck-Nicolaides team soon produced important papers on the use of fetoscopy in the management of a wide range of conditions such as Rhesus iso-immunization, fetal hydrops and intrauterine growth restriction, and procedures such as blood and tissue sampling in the diagnosis of single gene defects.

External cephalic version (ECV) is a process by which a breech baby can sometimes be turned from buttocks or foot first to head first. It is a manual procedure that is recommended by national guidelines for breech presentation of a pregnancy with a single baby, in order to enable vaginal delivery.
In humans, scaphocephaly is a form of dolichocephaly. Dolichocephalic dogs (such as the Lurcher or German Shepherd) have elongated noses. This makes them vulnerable to fungal diseases of the nose such as aspergillosis. [1] In humans the anterior–posterior diameter (length) of dolichocephaly head is more than the transverse diameter (width).
The anomaly scan, also sometimes called the anatomy scan, 20-week ultrasound, or level 2 ultrasound, evaluates anatomic structures of the fetus, placenta, and maternal pelvic organs. This scan is an important and common component of routine prenatal care . [ 1 ]
