Abdominal Ultrasound
Abdominal ultrasound is specifically used to detect any abnormalities of the abdominal organs and other structures in the upper abdominal regions. An abdominal ultrasound can aid in determining the cause of abdominal pain or monitoring an abdominal aneurysm. It is mainly used to detect gall stones and tumors. Problems of the liver such as jaundice, cirrhosis or fatty deposits can be evaluated with abdominal ultrasound. Enlarged spleen, pancreatis and blocked bile ducts can be diagnosed with an abdominal ultrasound. Extreme obesity and gas or other materials in the stomach or intestines can affect the accuracy of an abdominal ultrasound. An abdominal ultrasound can aid placement of needle or other instrument during biopsy. Any fluid buildup in the abdominal cavity can be detected.
Ultrasound
Ultrasound is a medical imaging technique that is also called ultrasound scanning or sonography. High frequency sound waves and their echoes and used in this technique for obtaining images from inside the human body. The echoes of sound waves reflected from the human body are recorded and displayed as a real-time visual image. This technique is similar to the echolocation used by bats, whales and dolphins. The sonar used by submarines also operates the same technique. Ultrasound is useful method to examine many of the body's internal organs like heart, liver, gallbladder, spleen, pancreas, kidneys and bladder. Movement of the internal tissues and organs are captured in ultrasound. This enables the physicians to diagnose a variety of disease conditions and also assess the damage caused to the systems.
The ultrasound machine transmits high frequency sound pulses into the human body by using probes. These sound waves that travel into the body hit a boundary between the tissues inside the body and reflect the sound waves to the probe. Some waves travel even further and they reach another boundary and then get reflected back. The waves that are reflected are picked up by the probe and relayed back into the ultrasound machine.
The ultrasound machine in turn calculates the distance from the probe to the tissue or organ by using the speed of sound tissue and the time of each echo's return. The machine displays these distances and intensities of the echoes on the screen. Through the echoes that are produced the sonologist can identify how far away an object is, how large it is, its shape and consistency (fluid, solid or mixed). Two dimensional images are formed and reflected on the screen. Different types of ultrasound are used for different disease conditions. Ultrasound is used in a variety of clinical settings including obstetrics and gynecology, cardiology and cancer detection. The abdominal ultrasound, pelvic ultrasound and transvaginal ultrasound are commonly used.
Pelvic Fracture
Fractures of the pelvis account only for about 0.3-6% of all fractures. A pelvic fracture can simply be described as a break in one or more bones comprising the pelvis. Pelvic fracture is a serious condition and requires immediate medical intervention.
The worst pelvic fractures are caused by high-speed accidents such as car accidents or motorcycle accidents or falls from high places, which have major impact on the body. The greater the force, the more severe the fracture. Depending upon the direction and degree of the force, these injuries can be life threatening.
Other injuries such as broken bones or damage to liver, kidneys or other organs.
Pelvic fracture also occurs in people with osteoporosis.
Pelvic fracture occurs among teens, involved in sports and athletic activities such as football, hockey, skiing and long distance running. These fractures occur with sudden muscle contractions.
Pelvic fracture is usually caused by falls in elderly people, especially when getting out of a bathtub or descending stairs.
Symptoms of pelvic fracture include severe pain in the groin, hip or lower back area. The pain is bound to worsen when moving the legs. There may be pain in the abdomen and numbness and tingling sensation in the groin or legs. Bleeding from the vagina, urethra or rectum is often noticed with pelvic fractures. There may be difficulty in urinating and difficulty in walking or standing.
Types of Pelvic fractures
Stable or unstable pelvic fractures: In stable pelvic fracture, there is minimal hemorrhage. The break occurs in one point in the pelvic ring. In unstable pelvic fracture, the pelvis becomes unstable. The break occurs in two or more break points in the pelvic ring. There occurs moderate to severe hemorrhage.
Open or closed pelvic fractures: If open skin wound occurs during the fracture in the lower abdomen, it is called open pelvic fracture. If no skin wounds occur, then it is closed pelvic fracture.
Diagnostic tests such as x-rays, CT scans are used to diagnose pelvic fractures. MRI allow a detailed picture of the pelvic area. Abdominal ultrasound is used to find internal bleeding and other injuries within the abdomen. Urethrography may be conducted to check injuries in urethra by means of an injected dye. Arteriography, in which dye is injected in the arteries to check for internal bleeding within the pelvis, is sometimes used.
Treatment to the pelvic fracture depends upon the severity of the injury caused. A pelvic fracture is a serious injury. In some cases, it may be complicated with injuries in other parts of the body and severe shock as well. Sometimes severe internal and external bleeding and damage to the internal organs could occur. In these situations, immediate attempt is made by the emergency doctor to stop internal and external bleeding caused by the injury. In case of minor fracture, the treatment would merely consist of bed rest and painkillers.
Most of the times, surgery is undertaken to repair the pelvic fracture. Healing after surgery can take anywhere between few weeks to several months. Thus a lengthy rehabilitation becomes necessary after an extensive pelvic surgery.
