OBJECTIVE: The aim of this study was to correlate clinical, histologic, and morphometric features of the liver in children with extrahepatic portal vein thrombosis (EHPVT), with surgical outcome after Meso-Rex bypass (MRB). BACKGROUND: Idiopathic EHPVT, a significant cause of portal hypertension, is surgically corrected by MRB. Correlation of histologic and morphometric features of the liver with outcome has not been reported in children. METHODS: We retrospectively reviewed clinical and intraoperative data of 45 children with idiopathic EHPVT...

Vascular complications continue to have devastating effect; although their nature, incidence and outcome might have actually changed with increasing experience and proficiency in high volume centers. Aim was to analyze the trends observed in vascular complications with changing protocols in adult and pediatric- living donor liver transplantation (A-LDLT and P-LDLT) over 10 years in two time frames in terms of nature, incidence and outcome. It is a retrospective analysis of 391 (Group I= Jan. 2006- Dec.2010) and 741 (Group II= Jan...

Extrahepatic portal vein obstruction, although rare in children, is a significant cause of portal hypertension (PHT) leading to life-threatening gastrointestinal bleeding in the pediatric age group. PHT may also lead to other complications such as hyperesplenism, cholangyopathy, ascites, and even hepatopulmonary syndrome and portopulmonary hypertension that may require organ transplantation. Herein we report the case of an asymptomatic 11-month-old infant wherein a hepatomegaly and cavernous transformation of the portal vein was detected by liver ultrasound...

Splenectomy is attended by medical complications, principally infectious and thromboembolic; the frequency of complications varies with the conditions that led to splenectomy (hematologic splenectomy, trauma, presence of portal hypertension). Most infectious complications are caused by encapsulated bacteria (Meningococcus, Pneumococcus, Hemophilus). These occur mainly in children and somewhat less commonly in adults within the first two years following splenectomy. Post-splenectomy infections are potentially severe with overwhelming post-splenectomy infection (OPSI) and this justifies preventive measures (prophylactic antibiotics, appropriate immunizations, patient education) and demands prompt antibiotic management with third-generation cephalosporins for any post-splenectomy fever...

Vascular pathology is ubiquitous in children. Common indications for angiographic imaging in the body include congenital anomalies, portal hypertension, assessing resectability of neoplasms, renovascular hypertension, vascular malformations, vasculitis, systemic vein thrombosis, and trauma. MR angiography, with or without the use of intravenous contrast agents, is therefore a mainstay in the repertoire of MR imaging in children. Pediatric contrast-enhanced MR angiography has benefited from several innovations in recent years, including improved hardware options like high-field-strength scanners and integrated high-density coil arrays, new sequences that combine parallel imaging, innovative k-space sampling and Dixon fat suppression with time-resolved imaging, new contrast agents with longer blood-pool residence time, and advanced post-processing solutions like image fusion...

Unlike in adults, contrast agent-enhanced magnetic resonance (MR) angiography in the pediatric population raises unique challenges such as faster heart rates, more rapid arteriovenous transit, smaller structures, smaller volumes of contrast agent used, and more complex disease processes. A need exists for a rapid contrast-enhanced MR angiographic technique that can separate the arterial and venous phases of contrast enhancement in sedated pediatric patients breathing freely during the course of an examination...

BACKGROUND: Splenectomy is performed frequently for various and primarily hematologic indications in children and adolescents. We analyzed the long-term outcome after splenectomy (median, 8.7 years) focusing on sepsis, portal vein thrombosis (PVT), and retained accessory spleen. METHODS: In total, 141 consecutive children after open (n = 89; 63%) or laparoscopic (n = 52; 37%) splenectomy from 1991 to 2010 were followed up through nationwide registries for septic infections, PVT, and causes of death...

OBJECTIVE: The mesoportal shunt (MPS) and liver transplantation (LT) have changed the scenario of extrahepatic portal vein obstruction (EHPVO) since the MPS, the only "curative" technique, can now be offered in asymptomatic patients and also thrombotic complications of LT have increased the incidence of EHPVO. MATERIAL AND METHODS: A retrospective study of patients undergoing surgery for EHPVO was conducted between 1990 and 2015. An analysis was done for the shunt permeability and clinical evolution over time...

UNLABELLED: Approaches to the management of portal hypertension and variceal hemorrhage in pediatrics remain controversial, in large part because they are not well informed by rigorous clinical studies. Fundamental biological and clinical differences preclude automatic application of approaches used for adults to children. On April 11-12, 2015, experts in the field convened at the first Baveno Pediatric Satellite Meeting to discuss and explore current available evidence regarding indications for MesoRex bypass (MRB) in extrahepatic portal vein obstruction and the role of primary prophylaxis of variceal hemorrhage in children...

BACKGROUND: The association of pancreatitis and portal vein thrombosis (PVT) is extremely rare in children. We report on 3 cases which suggest that there may be a causal relation between the two. METHODS: Clinical characteristics and evolution of 3 children with this particular condition were analyzed retrospectively. In this group of patients, the strategy consisted in opting for early surgical decompression of the portal hypertension, which was followed by a favorable outcome, not only in terms of complications related to the portal hypertension but also of a contemporaneous spontaneous regression of the concurrent pancreatic disease, in absence of any other specific management of the latter problem...
