Abstract:Budd-Chiari syndrome (BCS), also known as hepatic venous outflow tract obstruction includes a group of conditions characterized by obstruction to the outflow of blood from the liver secondary to involvement of one or more hepatic veins (HVs), inferior vena cava (IVC) or the right atrium. There are a number of conditions that lead to BCS-ranging from hypercoagulable states to malignancies. In up to 25% patients, no underlying disorder is identified. Diagnosis of BCS is based on a combination of clinical and ima… Show more
“…Caudate lobe may demonstrate better venous enhancement due to its unique venous drainage pattern. A “flip-flop” pattern may occur in the portal venous phase as the central part of the liver demonstrates low attenuation due to contrast wash-out and gradual increase of the peripheral attenuation [ 26 ].

Differential diagnosis in non-traumatic acute abdomen is broad and unrelated diseases may simulate each other from a clinical perspective. Despite the fact that they are not as common, acute abdominal pain due to diseases related to visceral vessels may be life-threating if not detected and treated promptly. Thrombosis, dissection, and aneurysm in the abdominal visceral arteries or thrombosis in visceral veins may cause acute abdominal pain. Imaging with appropriate protocoling plays a fundamental role in both early diagnosis and determination of the treatment approach in these cases where early treatment can be life-saving. Computed tomography (CT) appears to be the most effective modality for the diagnosis as it provides high detail images in a very short time. Patient cooperation is also a less concern as compared to magnetic resonance imaging (MRI). As the imaging findings may sometimes be really subtle, diagnosis may be difficult especially to inexperienced imagers. Correct protocoling is also very critical to detect arterial abnormalities as visceral arterial abnormalities may not be detectable in portal phase only abdominal CT scans. In this article, we aimed to increase awareness among imaging specialists to these not very common causes of acute abdomen.

“…Budd-Chiari syndrome (BCS) is characterized by obstruction to the hepatic venous outflow at the level of IVC or hepatic veins. Predisposing factors include hypercoagulable states, which can be both congenital and acquired [ 28 ]. Pregnancy itself is a risk factor for BCS, but additional risk factors are usually present [ 29 ].…”
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.
