Screening is widely used to detect early hepatocellular carcinoma in Asian patients with cirrhosis. Its effectiveness in Caucasian patients has been suggested, but remains to be proven. Therefore we prospectively studied 118 French patients (68 males, 50 females, age 55 +/- 12) with Child-Pugh A or B cirrhosis (alcoholic in 82) and without detectable hepatocellular carcinoma. The screening program consisted of ultrasound examination of the liver and determination of blood alpha-fetoprotein and des-gamma-carboxyprothrombin levels every 6 months. The median follow up was 36 months (range 4-48). Only four patients were lost to follow up. Fourteen hepatocellular carcinomas were detected, in six cases by ultrasonography alone, in four by alpha-fetoprotein alone, in three by ultrasonography and alpha-fetoprotein and in one case by ultrasonography and des-gamma-carboxyprothrombin, but never by des-gamma-carboxyprothrombin alone. The tumor presented as a unique nodule in nine patients. The tumor was less than 3 cm in diameter without portal thrombosis or metastasis in three cases. Surgery was performed in only one case. In this study, the annual incidence of hepatocellular carcinoma was high (5.8%), but the screening methods used did not effectively identify potentially resectable tumors in Caucasian patients with cirrhosis.

Orthotopic liver transplantation (OLT) is nowadays accepted as the best therapy for end-stage liver disease. The difficulties involved are even greater in children than in adults, and it is debatable whether exclusively pediatric programs are warranted. The aim of this paper is to analyze our experience at the Children's Hospital "La Paz", with the first consecutive 100 OLT in children, 61% of whom weighed less than 20 kg. Since 1986, 220 pediatric patients were evaluated as candidates, 100 OLT were performed in 78 patients and 13 died on the waiting list, currently maintained below 15 cases. Indications were: cholestasis (45), metabolic disease (18), fulminant hepatic failure (3), primary liver tumors (2) and cirrhosis (10). Mean age was 66 months (range = 7 to 216) with a mean weight of 21 kg (range = 6 to 60), twenty patients weighed less than 13 kilograms. OLT was performed by standard technique. Reduced or segmental grafts were necessary in 8 instances. Twenty-two patients were retransplanted and 2 received three grafts. Indications for retransplantation were: hepatic artery thrombosis (8), primary nonfunction (4), chronic rejection (7), portal thrombosis (2) and Budd-Chiari recurrence (1). Acute rejection was observed in 52 patients, and eight cases developed a chronic rejection. These episodes were treated with "bolus" of steroids, monoclonal antibodies (OKT-3) and FK-506. Surgical complications included: hepatic artery thrombosis 12%, portal vein thrombosis 3% and biliary fistula or stenosis 13%. The incidence of primary non-function was 7%. Actuarial survival rate at 5 years was 75%.(ABSTRACT TRUNCATED AT 250 WORDS)

Eleven liver cirrhosis patients with variceal bleeding and/or ascites were treated by transjugular intrahepatic portosystemic shunt. Four of the patients were combined with hepatoma, and 2 had portal thrombosis. Ten of the patients were successfully achieved TIPS, but one patient who had portal thrombosis was failed because of portal vein occlusion; success rate of 90%. An average decrease of 14mmHg in portal vein pressure was measured in the 10 patients. All of the successful patients including 4 with hepatoma were observed the disappeared or diminished varices and ascites without technical complication. Mild encephalopathy was encountered in 2 patients but who responded well to medical therapy. Three dimension MRA before TIPS was helpful for understanding the anatomical relationship between portal vein and hepatic vein. It is concluded that TIPS is an effective and safe treatment, indicating for the patients who have uncontrollable variceal bleeding and/or ascites even with hepatoma.

Portal vein thrombosis is often considered a contraindication to orthotopic liver transplantation. We have analyzed the incidence, risk factors, management and outcome of patients with portal vein thrombosis undergoing orthotopic liver transplantation. During the period from October 1988 to October 1992 140 grafts were performed on 132 patients. Fourteen had portal vein thrombosis with either partial (n = 7) or complete (n = 7) occlusion of the portal vein at surgery. Portal vein thrombosis was more common in patients with autoimmune chronic active hepatitis (3/5 vs. 11/127, chi 2 = 13.3, P < 0.001), cryptogenic cirrhosis (4/12 vs. 10/120, chi 2 = 7.2, P < 0.01), or those with tumors (6/22 vs. 10/110, chi 2 = 5.7, P < 0.05). In 13 of the 14 portal inflow was reestablished by flushing, balloon thrombectomy, or passage of a graduated dilator. In one patient complete fibrous obliteration necessitated a portal vein to right gastroepiploic vein anastomosis. On follow-up there have been 6 deaths in this group (6/14 = 43%) from recurrent cancer (n = 1), sepsis (n = 4), and cardiac and renal failure (n = 1). Four of these 6 patients had confirmation of PV patency on imaging. The remaining 8 patients are alive and well (median follow-up 37 months, range 6-53 months). Post-transplant portal vein thrombosis occurred in 3 of the 14 patients (21%) with a portal vein abnormality at surgery and in two of the 118 patients with a normal portal vein (3/14 vs. 2/118, chi 2 = 8.5, P < 0.01). Four of the 5 cases were successfully treated by surgical thrombectomy.

Portal vein thrombosis (PVT) is usually a complication of pre-existing cirrhosis, abdominal malignancy (e.g., pancreatic or hepatocellular carcinoma), or abdominal inflammation (e.g., appendicitis, diverticulitis, pancreatitis). Less frequently, PVT can be associated with myeloproliferative or connective tissue disorders or inflammatory bowel disease [1]. PVT can cause or exacerbate portal hypertension; variceal bleeding or hypersplenism may then develop acutely or several years later. PVT also complicates portosystemic shunt surgery or hepatic transplantation. Unfortunately, the signs and symptoms of PVT can be subtle or nonspecific and can be overshadowed by the underlying illness. The radiologist may be the only physician to suggest the preoperative or premortem diagnosis of PVT. Familiarity with the imaging findings of PVT, therefore, is imperative.

We report on a case of early portal vein thrombosis occurring after liver transplantation in a patient with alcoholic cirrhosis. Although this complication is usually accompanied by acute graft failure and/or gastroesophageal bleeding, in this patient the portal thrombosis occurred with the appearance of general dropsy and encephalopathy, serum protein deficiency and a slight rise in liver function test values. Echo-Doppler and arteriography showed portal thrombosis, arterial hyperflow and the persistence of a large spontaneous spleno-renal shunt, identified before the transplant had taken place. Endoscopy did not reveal gastroesophageal varices. Since there was no sign of serious ischemic damage or of a serious deterioration of liver function, the patient was treated non-operatively. Some particular hemodynamic aspects implicated in the appearance of portal thrombosis in our case are discussed. However, the authors consider that spontaneous portal-systemic shunt, in the presence of advanced cirrhosis, inverted portal flow, without gastroesophageal varices, can be considered as a surgical total diverting shunt and should be taken as a risk for portal thrombosis after transplantation.

From January 1986 to September 1995, 4 patients were hospitalized in our ward for gastrointestinal bleeding from ectopic varices. The patients were all female, aged 30 to 65 years. The etiology of portal hypertension in these patients was alcoholic cirrhosis, cirrhosis in Wilson's disease and previous alveolar echinococcosis treated by right hepatectomy, complicated by post-operative portal thrombosis. Clinical presentation in all 4 cases was lower gastrointestinal bleeding. Diagnosis was by emergency arteriography in 3 cases; no source was found in one case with recurrent hemorrhage. The 4 patients had a history of abdominal surgery. The location of the ectopic varices was small bowel and cecum. 3 patients were treated surgically: right colectomy, partial small bowel resection and porto-caval shunt with complete lysis of adhesions. One patient was treated conservatively with emergency placement of a TIPS (transjugular intrahepatic porto-systemic shunt), with simultaneous embolization of cecal varices. Upon laparotomy, all 3 surgical cases presented ectopic varices in post-operative adhesions. In conclusion, in a patient with portal hypertension presenting with lower gastrointestinal bleeding, hemorrhage from ectopic varices should be kept in mind and investigated by arteriography. A history of abdominal surgery seems to be a predisposing factor in development of ectopic varices by adhesion formation.

Portal hypertension is a relatively uncommon pathologic condition in children and young adults in contrast with older adults. The aim of this study is to evaluate the utility of sonography and color Doppler sonography in the diagnosis of portal hypertension in children and young patients and to evaluate the sonographic pattern of each disease. We reviewed 25 such patients who were younger than 30 years old and obtained the following sonographic findings: (1) liver cirrhosis: (a) multiple intrahepatic venovenous shunts in patients with primary Budd-Chiari syndrome and (b) intrahepatic vascular narrowing and nodular coarse parenchymal texture, with multiple very-high-echo spots along the portal vein in patients with Wilson disease; (2) congenital hepatic fibrosis: marked and developed collaterals, wide periportal echogenic band, and a heterogeneous parenchymal texture comprised of multiple high echoes but without portal thrombus; and (3) extrahepatic portal thrombosis: invisible portal lumen except as an echogenic band. Sonography and color Doppler sonography are very useful in diagnosing these portal hypertensive diseases. However, there are no specific sonographic findings, and the role of sonography is limited to follow-up observation of associated secondary hepatobiliary changes in patients with congenital biliary atresia.

The prognosis for patients with primary liver cancer (PLC) often depends on tumor recurrence and the development of extrahepatic metastases, particularly after liver transplantation. We have developed a sensitive test to detect both spontaneous circulation of tumor cells and the spread of liver cells due to chemoembolization and alcoholization. Reverse-transcription polymerase chain reaction was used to search for cells expressing alpha-fetoprotein (AFP) messenger RNA in the peripheral blood of 84 patients with PLC and 102 controls (55 patients with chronic hepatitis and/or cirrhosis, 10 patients with benign liver tumors or liver metastases from intestinal cancers, and 37 healthy individuals). By spiking the blood of healthy volunteers with HepG2 cells, we assessed the sensitivity limit: one HepG2 cell mixed with 10(7) leukocytes. All 102 controls tested negative. In contrast, 28 patients (33.3%) with PLC tested positive. Positivity for the test was significantly associated with portal thrombosis, tumor size, intravascular tumor emboli, serum AFP level, and extrahepatic metastases. Patients were followed up for a mean period of 39 +/- 51 weeks: the probability of developing extrahepatic metastases was significantly higher in positive than in negative patients. Eighteen negative patients with PLC were tested before, 1 hour after, and 24 hours after locoregional therapy: 9 tested positive either 1 or 24 hours after alcoholization or chemoembolization. In conclusion, we have developed a highly specific and sensitive test to detect circulating tumor cells in patients with PLC. This test is likely to be clinically useful in evaluating the risk of developing extrahepatic metastases and the possibility of iatrogenic spreading of liver-derived, possibly tumorous, cells.

A case of hepatic infarction with portal thrombosis is reported. A 63-year-old woman with liver cirrhosis and esophageal varices was admitted for treatment of the esophageal varices. Endoscopic variceal ligation (EVL) and endoscopic injection sclerotherapy (EIS) were performed. Two months later, she experienced right hypochondralgia and right flank pain. Serum transaminase levels were suddenly elevated, and computed tomography scans of the liver showed multiple small nodular lesions. Her condition worsened, and she died of hepatic failure. Autopsy revealed splenic and portal vein thrombosis, multiple hepatic infarction, and evidence of chronic pancreatitis. We believe that liver cirrhosis and chronic pancreatitis were the main risk factors for the portal thrombosis, and the treatment for esophageal varices appeared to have triggered the thrombosis. The hepatic infarction was caused by the portal thrombosis.
