PURPOSE: To assess frequency of adverse events, efficacy, and clinical outcomes of percutaneous portal vein embolization (PVE) in patients with bilobar colorectal liver metastases undergoing staged hepatectomy with preservation of segment IV ± I only. MATERIALS AND METHODS: Retrospective analysis was performed of 40 consecutive patients who underwent right PVE after successful left lobectomy between 2005 and 2013. Rates of adverse events, future liver remnant (FLR) > 30% compared with baseline liver volume, clinical success (completion of staged hepatectomy with clearance of liver metastases), and overall survival were analyzed...

While hepatic tuberculosis is rare, primary tubercular liver abscess (TLA) is a rarer condition even in endemic countries such as India. Liver abscess in portal cavernoma cholangiopathy (PCC) is predominantly pyogenic. A 14-year-old girl was found to have PCC with multiple liver abscesses. Persistent fever and development of neurological symptoms prompted further evaluation, and she was found to have primary TLA complicated by tubercular meningitis. We report a rare case of primary TLA complicated by tubercular meningitis in asymptomatic PCC...

Portal biliopathy (PB) is defined as the presence of biliary abnormalities in patients with non-cirrhotic/non-neoplastic extrahepatic portal vein obstruction (EHPVO) and portal cavernoma (PC). The pathogenesis of PB is due to ab extrinseco compression of bile ducts by PC and/or to ischemic damage secondary to an altered biliary vascularization in EHPVO and PC. Although asymptomatic biliary abnormalities can be frequently seen by magnetic resonance cholangiopancreatography in patients with PC (77%-100%), only a part of these (5%-38%) are symptomatic...

Primary prophylaxis in portal hypertension in children is controversial, because there are few studies documenting its efficacy on the risk of bleeding. Twenty-eight centres out of the 38 we contacted returned a completed questionnaire about their clinical practices. More than 75% of the centres use endoscopy to screen patients diagnosed with portal cavernoma, biliary atresia, cystic fibrosis, and other fibrotic chronic liver diseases with suspected portal hypertension. In cases of grade 2 varices with red marks and grade 3 varices >90% of centres perform sclerotherapy or endoscopic variceal ligation...

Paroxysmal nocturnal hemoglobinuria (PNH) is associated with severe end-organ damage and a high risk of thrombosis. Budd-Chiari syndrome, which develops after thrombotic occlusion of major hepatic blood vessels, is relatively common in PNH and has been associated with increased mortality. We report the case of a 46-year-old male with PNH who presented with Budd-Chiari syndrome associated with portal cavernoma, portal hypertension and hypersplenism. In September 2010, the patient suffered gastrointestinal bleeding, hematuria, and elevated plasma lactate dehydrogenase; he started eculizumab therapy with a good response...

OBJECTIVE: To characterize biliary abnormalities seen in portal cavernoma cholangiopathy (PCC) on MR cholangiopancreaticography (MRCP) and elucidate certain salient features of the disease by collaborating our findings with those of previous studies. METHODS: We prospectively enrolled 52 patients with portal cavernoma secondary to idiopathic extrahepatic portal vein obstruction, who underwent a standard MRCP protocol. Images were analyzed for abnormalities involving the entire biliary tree...

Although transjugular intrahepatic portosystemic shunts are most frequently used for the management of portal hypertension, the surgical approach is preferred for symptomatic portal cavernoma cholangiopathy. We present the case of a 25-year old female patient with a portal cavernoma secondary to catheterization of the umbilical vein at birth. She had had two episodes of esophageal variceal bleeding, successfully treated by endoscopic banding. and an episode of acute cholangitis secondary to portal cavernoma cholangiopathy...

Portal biliopathy refers to cholangiographic abnormalities which occur in patients with portal cavernoma. These changes occur as a result of pressure on bile ducts from bridging tortuous paracholedochal, epicholedochal and cholecystic veins. Bile duct ischemia may occur due prolonged venous pressure effect or result from insufficient blood supply. In addition, encasement of ducts may occur due fibrotic cavernoma. Majority of patients are asymptomatic. Portal biliopathy is a progressive disease and patients who have long standing disease and more severe bile duct abnormalities present with recurrent episodes of biliary pain, cholangitis and cholestasis...

Portal vein thrombosis is observed in up to 10% of liver transplant candidates, hindering execution of the procedure. A dilated gastric vein is an alternative to portal vein reconstruction and decompression of splanchnic bed. We present two cases of patients with portal cavernoma and dilated left gastric vein draining splanchnic bed who underwent liver transplantation. The vein was dissected and sectioned near the cardia; the proximal segment was ligated with suture and the distal segment was anastomosed to the donor portal vein...

Extrahepatic portal vein obstruction (EHPVO) is a primary vascular condition characterized by chronic long standing blockage and cavernous transformation of portal vein with or without additional involvement of intrahepatic branches, splenic or superior mesenteric vein. Patients generally present in childhood with multiple episodes of variceal bleed and EHPVO is the predominant cause of paediatric portal hypertension (PHT) in developing countries. It is a pre-hepatic type of PHT in which liver functions and morphology are preserved till late...

BACKGROUND: Supra-mesocolic surgery (SMS) is complicated in patients with portal vein cavernoma (PC) and portal decompression is recommended. The aim of this study was to report a large single centre of SMS in patients with PC without portal decompression. METHODS: Between 2006 and 2013, all patients who met inclusion criteria were analyzed retrospectively. The primary endpoint was the feasibility rate, surgical and postoperative outcome. The secondary endpoints were the long-term outcome of patients who underwent biliary bypass for cholangitis...

Background. Portal cavernoma (PC) is the most critical condition with risk or variceal hemorrhage in pediatric patients. We retrospectively investigated the patients with PC focusing on the predictors for recurrent variceal bleeding. Methods. Between July 2003 and June 2013, we retrospectively enrolled all consecutive patients admitted to our department with a diagnosis of PC without abdominal malignancy or liver cirrhosis. The primary endpoint of this observational study was recurrent variceal bleeding. Independent predictors of recurrent variceal bleeding were identified using the logistic regression model...

Intraductal sonography generates high-resolution images of the entire length of the biliary tree and peribiliary tissues, including 3-dimensional dual- and muti-plane reconstructions to depict complex anatomy. Portal cavernoma cholangiopathy (previously called portal biliopathy) can have multiple etiologies of obstructive cholestasis in the same patient, which can be difficult to define even with advanced imaging techniques.We describe 2 difficult cases of portal cavernoma cholangiopathy in which intraductal sonography helped in clinical management decisions...

This article reports a patient with a de novo ∼ 9.32 Mb duplication at 16p13.3 and a ∼ 71 Kb deletion at 22q13.33. The patient was followed from 1 month old to 3 years and 8 months of age and presented typical features of the 16p13.3 duplication syndrome. In addition, the patient presents a portal cavernoma, an alteration rarely reported in this condition. Renal agenesis was detected as additional developmental defect. After genomic array and FISH analysis, the karyotype was 46,XX,ins(22;16)(q13;p13.2p13...

PURPOSE: Portal cavernoma follows a chronic occlusion of the portal vein. The long-term consequences of portal cavernoma are not well known. The objective of this study was to report the aetiology of the portal cavernoma and its natural course after excluding liver diseases causes. METHODOLOGY: A single centre retrospective study based on the data collected from the radiology department of the Clermont-Ferrand hospital was conducted from 2000 to 2011. All the patients for whom an imagery found a portal cavernoma have been looked for excluding the patients having a liver disease whatever the aetiology and the Budd-Chiari syndrome...
