Budd-Chiari syndrome (BCS) is a disorder with numerous causes that is a result of hepatic outflow obstruction, in the absence of right heart failure or constrictive pericarditis. Acute Budd-Chiari syndrome is uncommon and clinically characterized by ascites, hepatomegaly, and hepatic insufficiency. In the majority of cases, patients present with chronic BCS, showing a dysmorphic liver disease with variable fibrosis deposition. In chronic Budd-Chiari syndrome, hepatocellular carcinoma (HCC) and benign regenerative nodules (called large regenerative nodules or FNH-like lesions) have been described in the literature. Very few studies have reported magnetic resonance imaging (MRI) findings about these nodules, using hepatobiliary contrast medium. The aim of our review is to describe the magnetic resonance imaging findings of hepatic regenerative nodules in BCS, with emphasis on the hepatobiliary phase, and to compare the imaging features of benign nodules with those of HCC.

Objective: To assess the effects of inferior vena cava and/or hepatic vein (IVC±HV) venoplasty on liver volumetry and function in individuals with Budd Chiari syndrome (BCS) who present with ascites and at least one patent hepatic vein.

Methods: A retrospective analysis was conducted on the clinical data of 17 patients with BCS (6 males and 11 females, average age of 42.3 ± 11.

Catatonia may manifest as an independent entity or as a feature of a neuropsychiatric or medical illness. While electroconvulsive therapy (ECT) is the gold standard treatment for catatonia, it is typically administered if the patient's symptoms fail to respond to benzodiazepines. We describe the case of a 22-year-old male with Budd Chiari induced cirrhosis and no prior psychiatric history, who presented with symptoms of psychosis and hepatic encephalopathy, was treated in the ICU for multi-factorial delirium, developed symptoms of catatonia that failed to respond to lorazepam, ultimately requiring ECT with a favorable response.

Unlabelled: This article describes a case of a 26-year-old female with a history of Evan's syndrome who presented with severe exertional dyspnoea and abdominal discomfort. The patient was diagnosed with chronic Budd-Chiari syndrome, a rare vascular disorder characterized by obstruction of the hepatic vein. We discuss the risk factors, the clinical manifestations, and diagnostic methods for Budd-Chiari syndrome, as well as the possible association with an underlying incomplete systemic lupus erythematosus.

Budd-Chiari syndrome with obstruction in the inferior vena cava causes increased venous pressure in the azygous-hemiazygous system and paravertebral venous plexus, which is transmitted to the epidural venous plexus, devoid of the valves. It causes epidural venous plexus engorgement and venous congestion and may present rarely with low back pain or radiating pain. However, patients developing lower limb weakness as a complication of Budd-Chiari syndrome is an infrequent and severe presentation.

Article Synopsis
  • Budd-Chiari syndrome (BCS) is a rare, serious condition caused by blocked blood flow from the liver due to clotting.
  • Treatment usually requires long-term blood thinners and methods to unblock the veins.
  • This case report presents a new technique called hepatic venous thromboaspiration, which is used to help reopen the obstructed veins.
