The incidence of placenta and umbilical cord abnormalities is high in abnormal course of the delivery. Although the detection rate of umbilical cord abnormalities is steadily increasing with the improvement of ultrasound technology, and the fact that ultrasound scanning can distinguish umbilical cord conditions, this information has not exerted much impact on the management of labor to date. We believe prenatal detection of umbilical cord abnormalities must reduce the number of emergent cesarean sections and intrauterine fetal death. In this review, we describe the ultrasound diagnosis and management of major umbilical cord abnormalities, including abnormalities of cord insertion site (velamentous and marginal cord insertion), hypercoiled cord and nuchal cord, considering the current knowledge on physiologic and pathologic aspects of each umbilical cord abnormality.

Ultrasound I: Abdominal Ultrasonography

Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...
