Intrathoracic migration is an important complication of laparoscopic Nissen fundoplication. Most migrations are small and asymptomatic. We propose a simple and reproducible radiologic definition of two different types of intrathoracic migration of the wrap observed after laparoscopic Nissen fundoplication.
Because radiologic evaluation is necessary after surgery and for band adjustments, radiologists are involved in the postoperative follow-up and may be asked to perform those adjustments themselves.
The pronator teres muscle is rarely examined during a routine sonographic examination of the elbow joint. Nevertheless, it can be affected by a variety of conditions, including trauma and tumors, and can be implicated in compression of the median nerve. This pictorial essay first illustrates the anatomy and biomechanics of the pronator teres. Then we present the sonographic technique for examination, normal sonographic appearance, and anatomic variations of the pronator teres and adjacent structures as well as sonography of their main disorders. Normal and pathologic sonographic appearances are correlated with magnetic resonance imaging and radiographic results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
