Traumatic arteriovenous fistula (AVF) is not an uncommon disorder, but late discovery and the presentation of high-output heart failure is very rare. This patient did not know that he had traumatic AVF after a gunshot injury in the left thigh 14 years ago. The major presentation of the AVF was signs of heart failure. We performed surgical repair after making the diagnosis. The patient recovered with an uneventful course. This report stresses the importance of history-taking and physical examination in making the diagnosis of traumatic AVF.
RT 3D TEE can clearly delineate the geometries of defects in their entirety, including shape, size, and location of the defect and track canal. It would also appear that RT 3D TEE is superior to 2D TEE in the process of guiding the wire through the difficult canal anatomy, facilitating the overall procedure. The small mitral PVLs can be completely occluded, but subsequent complications occurred with large defect closures because of embolization or releak. Therefore, transcatheter closure of PVLs seems to be an attractive alternative for these patients, but newer occluder designs that better conform to leak geometry will be required to improve outcomes.
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.
