Objective:
To describe sonographic findings in livers of pregnant women with severe preeclampsia and abdominal pain.
Methods:
Over a 12-month period, we performed serial sonographic examinations on 32 pregnant women with severe preeclampsia and acute right upper quadrant and epigastric pain. On each sonogram we observed the liver size and texture, "periportal halo" sign, gallbladder wall, Glisson capsule thickness, painful compression of the liver and gallbladder, and ascites. The pancreas, spleen, kidneys, and uterus were also studied. Sonography was repeated after delivery.
Results:
Initial sonograms showed liver abnormalities in 28 patients. Abnormalities consisted of liver hypertrophy (n = 24), hyperechoic thickening of the periportal area (periportal halo sign; n = 23), striated thickening of the gallbladder wall (n = 27), hyperechoic thickening of the Glisson capsule (n = 11), liver areas of increased echogenicity (n = 11), subcapsular hematoma (n = 1), and subcapsular calcification (n = 1). Probe compression of the liver enhanced abdominal pain (n = 13), whereas the gallbladder was painless in all cases. No gallbladder stones were detected. Ascites (n = 16) and pleural effusion (n = 11) were also present. In no case did we detect abnormalities of the pancreas, kidneys, or spleen. All patients eventually had hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome according to the American College of Obstetricians and Gynecologists classification. In 7 cases, HELLP syndrome developed postpartum. Three patients also had eclampsia. Follow-up sonograms highlighted quick regression of abnormalities after delivery.
Conclusions:
The livers of women with severe preeclampsia who had HELLP syndrome showed sonographic abnormalities before biological abnormalities. Serial sonographic examinations could therefore contribute to the obstetric care of these women. Preeclampsia and HELLP syndrome should be routinely checked for in all pregnant women with acute abdominal pain.

01:20Ultrasound I: Abdominal Ultrasonography
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...
01:25Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.
