IVC anomalies are uncommon, usually of little physiological consequence, and mostly discovered incidentally during cross-sectional imaging in otherwise healthy individuals. However, they do have implications of relevance to surgeons because they may lead to significant complications during vascular interventional radiology procedures and retroperitoneal surgery when undiagnosed. This review synthesizes the current literature pertaining the development and identification of IVC anomalies, highlighting their possible implications for surgical procedures involving this retroperitoneal vessel.
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.
