Hiatal hernias are classified according to the increasing severity of protruding intra-abdominal viscera through the esophageal hiatus (types I-IV). Herein is the case of an elderly patient presenting with recent-onset dyspnea, postprandial gastroesophageal reflux, and hypoxemia. Imaging revealed a rare type IV hiatal hernia implicating the stomach and part of the pancreas. This case highlights the seemingly benign clinical manifestations of a massive hiatal hernia, despite its ability to complicate treatment or exacerbate comorbid conditions.
INTRODUCTION: Proximal aortic neck dilatation (PND) is associated with increased rate of complication after endovascular aneurysm repair (EVAR). Although many studies investigated PND after the placement of endografts that use self-expanding stents, there are no such reports for patients treated with endografts that use polymerfilled sealing rings. The purpose of this study is to examine PND and graft migration after EVAR with the Ovation stent graft.
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.
