Abstract
OBJECTIVES Non-cirrhotic portal vein thrombosis (PVT) is a main cause of portal hypertension in children. We describe the characteristics at presentation and outcome of a cohort of patients with PVT to determine clinical features and predictors of outcome. METHODS We recorded: (1) Associated factors: prematurity, congenital malformations, neonatal illnesses, umbilical vein catheterization (UVC), deep infections, surgery; (2) congenital and acquired prothrombotic disorders; (3) features at last follow up including survival rate and need for surgery. RESULTS 187 patients, mean age at diagnosis 4 ± 3.7 years, had a history of prematurity (61%); UVC (65%); neonatal illnesses (79%). The diagnosis followed the detection of splenomegaly (40%), gastrointestinal bleeding (36%), hypersplenism (6%), or was incidental (18%). Of 71 patients who had endoscopy at presentation 62 (87%) had oesophageal varices. After 11.3 years' follow up 63 (34%) required surgery or TIPS. Ten-year survival rate was 98%, with 90% shunt patency. Spleen size, variceal bleeding and hypersplenism at presentation were predictors of surgery or TIPS (p < 0.05). CONCLUSION PVT is associated with congenital and acquired co-morbidities. History of prematurity, neonatal illnesses and UVC should lead to rule out PVT. Large spleen, variceal bleeding and hypersplenism at presentation predict the need for eventual surgery in a third of cases.

Abstract
AIM: To study the management and outcome of children with extrahepatic portal vein obstruction (EHPVO) in a whole country population.
METHODS: A nationwide multicenter retrospective case series of children with EHPVO was conducted. Data on demographics, radiographic studies, laboratory workup, endoscopic and surgical procedures, growth and development, were extracted from the patients’ charts. Characteristics of clinical presentation, etiology of EHPVO, management and outcome were analyzed.
RESULTS: Thirty patients, 13 males and 17 females, 19 (63.3%) Israeli and 11 (36.7%) Palestinians, were included in the analysis. Age at presentation was 4.8 ± 4.6 years, and mean follow-up was 4.9 ± 4.3 years. Associated anomalies were found in 4 patients. The incidence of EHPVO in Israeli children aged 0-14 years was 0.72/million. Risk factors for EHPVO were detected in 13 (43.3%) patients, including 9 patients (30%) with perinatal risk factors, and 4 patients (13.3%) with prothrombotic states: two had low levels of protein S and C, one had lupus anticoagulant, and one was homozygous for methyltetrahydrofolate reductase mutations. In 56.6% of patients, no predisposing factors were found. The most common presenting symptoms were an incidental finding of splenomegaly (43.3%), and upper gastrointestinal bleeding (40%). No differences were found between Israeli and Palestinian children with regard to age at presentation, etiology and clinical symptoms. Bleeding occurred in 18 patients (60%), at a median age of 3 years. Sclerotherapy or esophageal banding was performed in 20 patients. No sclerotherapy complications were reported. Portosystemic shunts were performed in 11 patients (36.6%), at a median age of 11 (range 3-17) years: splenorenal in 9, mesocaval in 1, and a meso-Rex shunt in 1 patient. One patient underwent splenectomy due to severe pancytopenia. Patients were followed up for a median of 3 (range 0.5-15) years. One patient died aged 3 years due to mucopolysaccharidase deficiency type III. None of the patients died due to gastrointestinal bleeding.
CONCLUSION: EHPVO is a rare disorder. The etiological factors are still mostly unknown, and the endoscopic and surgical treatment options ensure a good long-term prognosis.

Abstract
OBJECTIVE To study a single-centre experience of the management of extrahepatic portal vein obstruction (EHPVO) in children during the last 3 decades. MATERIALS AND METHODS The medical records of 108 children (67 male, median age 4.75 years, range = 1 day-16.3 years) presenting with EHPVO between 1979 and 2005 were reviewed retrospectively. RESULTS Extended prothrombotic screening performed in 30 patients revealed low protein C activity (6 patients), low free protein S (2), and a positive lupus anticoagulant (1); factor V Leiden mutations and the JAK2V617F mutation were not identified. Associated congenital anomalies were found in 26 of the 108 children (24%). Clinical presentation included splenomegaly in 98 (91%) and ascites in 3 (3%). Elevation of liver enzymes and prolonged international normalized ratio were seen in 13 (12%) and 14 (13%) children, respectively. Haematological parameters of hypersplenism were present in 13 (12%). Bleeding occurred in 83 (77%) patients with a median age of 4.58 (0.02-16.37) years. On first endoscopy, oesophageal varices were present in 92 patients; of those subjects, 70 (76%) received sclerotherapy, 5 (5%) had band ligation, and 16 (17%) received both. Complications of endoscopy occurred in 34 (37%) patients: oesophageal ulcers in 16, oesophageal stricture in 10, both in 7, and erosive gastritis in 1. Seventeen (16%) children underwent shunt surgery for uncontrolled bleeding at a median age of 9.7 (5.2-23.7) years. CONCLUSIONS The aetiology of EHPVO in the majority of patients remains unknown. Sclerotherapy and banding are effective treatments for bleeding varices with good long-term outcome. Procoagulant state is an infrequent cause of EHPVO in children.

Abstract
Factor V (FV) G1691A mutation, in a heterozygous state, is one of the most common inherited risk factors for development of thrombosis. However, the clinical manifestations of homozygosity for the FV G1691A mutation in children is largely unknown because of the limited number of studies reported. The purpose of this study was to evaluate the clinical manifestations and laboratory findings of children with thrombosis who were homozygous for this mutation. Ten patients (four male/six female; mean age, 4.5 years; age range, 1-13 years) who were found to be homozygous for the FV G1691A mutation among 360 consecutive children with thrombosis (2.8%) were the subjects of this study. Six of the 10 patients had venous thrombosis, two had purpura fulminans, one had diffuse skin ecchymosis and one had arterial thrombosis. No history of thrombosis was present in their family members. Seven of the 10 children were under the age of 5 years. One or more additional risk factors (infection, protein S and protein C deficiencies, elevated factor VIII, etc.) were also present in nine of these patients. None of these patients had prothrombin G20210A mutation but one patient had risk-associated plasminogen activator inhibitor-1 gene 4G/4G genotype. These findings suggest that, in the presence of other underlying risk factors, homozygosity for FV G1691A mutation may lead to development of thrombosis at a very young age.

Abstract
OBJECTIVE Mortality of extrahepatic portal vein thrombosis depends on underlying causes other than gastrointestinal bleeding. The aim of this study was to evaluate the etiology, treatment, and prognosis of patients with extrahepatic portal vein thrombosis. METHODS The records of 12 patients (age range: 1-9 years) diagnosed with extrahepatic portal vein thrombosis with a minimum follow-up of 2 years were analyzed retrospectively. Their diagnostic evaluations, treatment modalities, complications and long-term follow-ups were noted. RESULTS Mean follow-up period was 7.4 +/- 3.9 years (2-14 years). Hemorrhage from esophageal varices was the prevalent symptom in 6 patients (50%). Six patients had signs of hypersplenism, 5 were found to have thrombophilia: 2 protein C, 1 protein S, 1 combined protein S, C, and antithrombin III deficiency, and 1 homozygous factor V Leiden mutation. Two patients had congenital cardiovascular abnormalities, and 1 patient developed portal thrombosis after splenectomy operation. None of the patients who started propranolol prophylaxis before first bleeding episode bled during their follow-up periods. Endoscopic sclerotherapy succeed in 66.6% variceal hemorrhages. Shunt surgery was performed in 1 patient. The patients neither faced a life-threatening variceal bleeding nor died during follow-up period. CONCLUSION Prognosis of extrahepatic portal vein thrombosis is good in childhood. Thrombophilic states are the most frequent precipitating causes. Propranolol for prophylaxis of variceal bleeding and sclerotherapy might be the preferred modalities.

Abstract
Three neonates with fetal thrombotic vasculopathy in the placenta and severe neonatal liver disease are described. Symptoms included a bleeding disorder on the first day of life, followed by direct hyperbilirubinemia and elevated liver transaminases. All patients also had evidence of thrombosis outside the placenta, including cerebral infarct in two infants and thrombosis of the inferior vena cava in one infant. Liver disease was demonstrated to be thrombotic in one infant who died with Budd-Chiari syndrome. Two infants survived and had liver biopsy with cholestasis, bile duct proliferation, and portal fibrosis demonstrated at 4 weeks and 11 weeks of age, respectively. The etiology of thrombosis is unknown, though in one patient an excessively long and coiled umbilical cord may be implicated. The prenatal onset of thrombosis suggests an inherited or acquired thrombophilic state. In cases of enigmatic neonatal liver disease, an association with thrombosis should be considered and thrombi sought in placenta, umbilical cord, major blood vessels, and other organs. Evaluation for a hypercoagulable state is also suggested.

Abstract
The factor V (FV) G1691A mutation, the prothrombin (PT) G20210A variant, the methylenetetrahydrofolate reductase (MTHFR) T677T genotype, together with fasting homocysteine (HCY) concentration, lipoprotein (Lp)(a), anti-thrombin (AT), protein C (PC), protein S (PS) and anti-cardiolipin antibodies were investigated in 65 consecutively recruited infants (neonate to < 12 months) with renal venous thrombosis (RVT; n = 31), portal vein thrombosis (PVT; n = 24) or hepatic vein thrombosis (HVT n = 10), and 100 age- and sex-matched healthy controls. FV G1691A was found in 14 babies (heterozygous: RVT n = 9, PVT n = 4; homozygous HVT n = 1) and five controls, the MTHFR TT677 genotype together with increased HCY in four infants with thrombosis (RVT n = 2; PVT n = 1; HVT n = 1) compared with one control, and the PT G20210A variant was present in one control only. PC type I deficiency was diagnosed in three patients (RVT n = 2; PVT n = 1) and AT deficiency in two patients (RVT n = 1; PVT n = 1). Three neonates with spontaneous thrombosis showed FV G1691A combined with Lp(a) and the FV G1691A was combined with the PT G20210A genotype in two infants. Additional triggering factors were reported in 27 patients (41.5%). The overall odds ratios (ORs) and 95% confidence intervals (CIs) with respect to the different thrombosis locations were: RVT (OR/CI: 10.9/3.85-31.1; P < 0.0001), PVT (5.47/1.7-17.6; P < 0.0007) and HVT (3.3/0.58-18.7; P = 0.18). The data presented here suggest that genetic prothrombotic risk factors also play an important role in abdominal venous thrombosis during infancy.
