Massive hemobilia is a well recognized clinical entity, particularly when it presents with jaundice, GI bleeding, and biliary pain. However, occult hemobilia is more difficult to diagnose and has seldom been reported because of its clinically silent nature. In fact, this is usually overlooked until complications arise. Hemocholecyst or clot within the gallbladder may rarely occur in this setting, leading to cystic duct obstruction and cholecystitis. Most previous reports describe cholecystitis resulting from hemocholecyst after iatrogenic trauma. We describe two cases in which hemocholecyst occurred from underlying malignancies, both resulting in cholecystitis (acute or chronic).
Continued smoking and failure to undergo DS within the first three postoperative months are modifiable factors associated with RVG occlusion. Smoking cessation and graft surveillance must be stressed to optimize patency of infrainguinal RVGs.
Flow velocity varies widely within and among AxFBGs. Patency of AxFBGs is associated with higher midgraft PSV, and thrombosis with midgraft velocities less than 80 cm/s.
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.
