Objective::
To determine the diagnostic accuracy of ultrasound to detect deep--vein thrombosis in pregnant patients.
Method::
We searched Pubmed, LILACS, Scopus, Google Scholar and System for Information on Grey Literature from inception to April 2016. The reference lists of the included studies were analyzed. Original articles from accuracy studies that analyzed ultrasonography to diagnose deep-vein thrombosis in pregnant women were included. Reference standard was the follow-up time. The QUADAS-2 score was used for quality assessment.
Results::
Titles and summaries from 2,129 articles were identified. Four studies that evaluated deep-vein thrombosis in pregnant women were included. In all, 486 participants were enrolled. High risk of bias was seen in three out of four studies included regarding flow and timing domain of QUADAS-2. Negative predictive value was 99.39%.
Conclusion::
Accuracy of ultrasonography to diagnose deep-vein thrombosis in pregnant women was not determined due to the absence of data yielding positive results. Further studies of low risk of bias are needed to determine the diagnostic accuracy of ultrasonography in this clinical scenario.

Ultrasound 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...
