RESUMO
BACKGROUND: Although congenital portosystemic shunts (CPSSs) are increasingly being recognized, the optimal treatment strategies and natural prognosis remain unclear, as individual CPSSs show different phenotypes. METHODS: The medical records of 122 patients who were diagnosed with CPSSs at 15 participating hospitals in Japan between 2000 and 2019 were collected for a retrospective analysis based on the state of portal vein (PV) visualization on imaging. RESULTS: Among the 122 patients, 75 (61.5%) showed PV on imaging. The median age at the diagnosis was 5 months. The main complications related to CPSS were hyperammonemia (85.2%), liver masses (25.4%), hepatopulmonary shunts (13.9%), and pulmonary hypertension (11.5%). The prevalence of complications was significantly higher in patients without PV visualization than in those with PV visualization (P < 0.001). Overall, 91 patients (74.6%) received treatment, including shunt closure by surgery or interventional radiology (n = 82) and liver transplantation (LT) or liver resection (n = 9). Over the past 20 years, there has been a decrease in the number of patients undergoing LT. Although most patients showed improvement or reduced progression of symptoms, liver masses and pulmonary hypertension were less likely to improve after shunt closure. Complications related to shunt closure were more likely to occur in patients without PV visualization (P = 0.001). In 25 patients (20.5%) without treatment, those without PV visualization were significantly more likely to develop complications related to CPSS than those with PV visualization (P = 0.011). CONCLUSION: Patients without PV visualization develop CPSS-related complications and, early treatment using prophylactic approaches should be considered, even if they are asymptomatic. LEVEL OF EVIDENCE: Level III.

BACKGROUND AND AIMS: Performing a Transjugular intrahepatic portal system shunt (TIPS) in patients with portal vein cavernous transformation (CTPV) poses significant challenges. As an alternative, transjugular extrahepatic portal vein shunt (TEPS) may offer a potential solution for these patients. Nonetheless, the effectiveness and safety of TEPS remain uncertain. This case series study aimed to evaluate the efficacy and safety of TEPS in treating patients with CTPV portal hypertension complications. METHODS: The study encompassed a cohort of 22 patients diagnosed with CTPV who underwent TEPS procedures. Of these, 13 patients manifested recurrent hemorrhagic episodes subsequent to conventional therapies, 8 patients grappled with recurrent or refractory ascites, and 1 patient experienced acute bleeding but refused endoscopic treatment. Comprehensive postoperative monitoring was conducted for all patients to rigorously evaluate both the technical and clinical efficacy of the intervention, as well as long-term outcomes. RESULTS: The overall procedural success rate among the 22 patients was 95.5% (21/22).During the TEPS procedure, nine patients were guided by percutaneous splenic access, three patients were guided by percutaneous hepatic access, five patients were guided by transmesenteric vein access from the abdomen, and two patients were guided by catheter marking from the hepatic artery. Additionally, guidance for three patients was facilitated by pre-existing TIPS stents. The postoperative portal pressure gradient following TEPS demonstrated a statistically significant decrease compared to preoperative values (24.95 ± 3.19 mmHg vs. 11.48 ± 1.74 mmHg, p < 0.01).Although three patients encountered perioperative complications, their conditions ameliorated following symptomatic treatment, and no procedure-related fatalities occurred. During a median follow-up period of 14 months, spanning a range of 5 to 39 months, we observed four fatalities. Specifically, one death was attributed to hepatocellular carcinoma, while the remaining three were ascribed to chronic liver failure. During the follow-up period, no instances of shunt dysfunction were observed. CONCLUSIONS: Precision-guided TEPS appears to be a safe and efficacious intervention for the management of CTPV.

Various congenital anomalies of the pancreas have been reported due to its complex embryological development involving the fusion of two separate buds. Circumportal pancreas is a rare anatomical anomaly where the pancreatic head and uncinate process fuse abnormally with the pancreatic body, encasing the portal vein and/or superior mesenteric vein completely. This anomaly poses several challenges to hepatobiliary surgeons, as the encasement of the portal vein by the abnormal pancreatic tissue makes an additional parenchymal transection necessary. Vascular variants have also been reported with circumportal pancreas, which, if not recognised preoperatively, can be catastrophic. Therefore, careful preoperative evaluation and planning are essential, to ensure safe pancreatic resection and recovery in a patient with circumportal pancreas. We present a case of a successful subtotal pancreatectomy and splenectomy in a patient with circumportal pancreas, for a suspected pancreatic duct adenocarcinoma. The aim of this case report is to contribute valuable insights that can aid hepatobiliary surgeons in enhancing their preoperative planning when encountered with patients with similar anatomical variances.

An 8-month-old female Maltese dog was referred for examination with a history of circling, dullness, and drooling. Serum biochemical analysis revealed hyperammonemia, with microhepatica observed on radiography. Computed tomography angiography revealed a portosystemic shunt originating from the right gastric vein and inserting into the prehepatic caudal vena cava. Portal blood flow to the liver was not observed. Based on computed tomography angiography, the dog was tentatively diagnosed with portosystemic shunt with portal vein aplasia. An exploratory laparotomy was done to obtain a definitive diagnosis. The dog had no subjective clinical signs of portal hypertension during a temporary occlusion test of the portosystemic shunt. A thin-film band was placed around the portosystemic shunt to achieve partial attenuation. There was no evidence of hepatic encephalopathy in the long term after surgery, and the dog's liver volume increased over time. Computed tomography angiography at 6 mo after surgery identified well-visualized intrahepatic portal branches. Key clinical message: We inferred that a direct occlusion test is a reliable diagnostic technique that overcomes the limitations of diagnostic imaging methods, including computed tomography angiography, and is a good technique for determining whether surgical attenuation is possible in dogs with suspected portal vein aplasia.
Atténuation chirurgicale réussie d'un shunt porto-systémique chez un chien avec une aplasie de la veine porte diagnostiquée par imagerie. Une femelle bichon maltais âgée de 8 mois a été référée pour examen avec une histoire de tournis, apathie et salivation excessive. L'analyse biochimique du sérum a révélé une hyperammionémie, avec un petit foie observé lors des radiographies. Une angiographie par tomodensitométrie a révélé un shunt porto-systémique prenant son origine de la veine gastrique droite et s'insérant dans la veine cave caudale pré-hépatique. Le flot sanguin porte au foie n'était pas observé. Sur la base de l'angiographie par tomodensitométrie, un diagnostic présumé de shunt porto-systémique avec aplasie de la veine porte a été émis. Une laparotomie exploratoire a été effectuée afin d'obtenir un diagnostic définitif. Le chien ne présentait pas de signe clinique subjectif d'hypertension portale durant un test d'occlusion temporaire du shunt porto-systémique. Une bande de film mince a été placée autour du shunt porto-systémique pour causer une réduction partielle. Il n'y avait aucune évidence d'encéphalopathie hépatique à long terme après la chirurgie, et le volume du foie du chien a augmenté dans le temps. Une angiographie par tomodensitométrie effectuée 6 mo après la chirurgie a permis de bien visualiser des branches portes intra-hépatiques.Message clinique clé :Nous avons déduit qu'un test d'occlusion est une technique diagnostique fiable qui surpasse les limites des méthodes d'imagerie diagnostique, incluant l'angiographie par tomodensitométrie, et est une bonne technique pour déterminer si une réduction chirurgicale est possible chez des chiens chez qui on soupçonne une aplasie de la veine porte.(Traduit par Dr Serge Messier).

El shunt portosistémico congénito es una anomalía vascular venosa que comunica circulación portal y sistémica, por la que se deriva el flujo sanguíneo, salteando el paso hepático. Es una entidad poco frecuente, cuya incidencia varía entre 1/30 000 y 1/50 000 recién nacidos. Puede cursar de forma asintomática o presentarse con complicaciones en la edad pediátrica o, menos frecuente, en la edad neonatal. Ante el diagnóstico, se deberá definir la necesidad de intervención quirúrgica o intravascular para el cierre. Esta decisión depende de las características anatómicas de la malformación, de las manifestaciones clínicas y complicaciones presentes. Se presenta el caso de un paciente de un mes de vida derivado a nuestro centro para estudio de hepatitis colestásica neonatal, con diagnóstico de shunt portosistémico extrahepático. Se realizó cierre intravascular de la lesión con mejoría significativa posterior.
Congenital portosystemic shunt is a venous vascular abnormality that connects portal and systemic circulation, resulting in diversion of the blood flow, bypassing the hepatic passage. It is a rare malformation; its incidence varies from 1:30 000 to 1:50 000 newborns. It may be asymptomatic or present with complications in the pediatric age or, less frequently, in the neonatal age. Upon diagnosis, the need for a surgical or an intravascular intervention for closure should be defined. This decision depends on the malformation anatomical characteristics, clinical manifestations, and complications. We present the case of a 1-month-old patient referred to our center for the study of neonatal cholestatic hepatitis, with a diagnosis of extrahepatic portosystemic shunt. Intravascular closure of the defect was performed with significant subsequent improvement.

El shunt porto sistémico congénito es una causa rara de hipoxemia y una patología muy poco frecuente con complicaciones severas si no es tratada. Fue descrito por primera vez por John Abernethy en 1793. Existen dos tipos: tipo I (shunt termino lateral) en el que hay ausencia total del flujo portal intrahepático y tipo II (shunt latero lateral) con flujo portal parcialmente conservado. Se presenta el caso de una niña de 6 años de edad con antecedente de hipoxemia crónica desde los 4 años y medio de vida, acompañado de disnea progresiva, quien fue referida a la unidad de neumología pediátrica con diagnóstico de cianosis central. Entre los estudios diagnósticos considerados se realizó ecografía doppler del sistema venoso portal, evidenciándose ausencia de vena porta principal; además se realizó angiotomografía del sistema arterio-venoso portal y mesentérico, confirmándose la agenesia de vena porta. Se completó el estudio con una porto-esplenografía que confirmó el diagnóstico de malformación de Abernethy tipo I b. La malformación de Abernethy tipo I es más frecuente en el sexo femenino, tiene varias formas de presentación y el tratamiento es el trasplante hepático. En la malformación de Abernethy tipo II la circulación portal es variable y tiene mejor pronóstico que la de tipo I. La disnea al ejercicio y la cianosis central es una forma de presentación que debemos tener en cuenta en el diagnóstico diferencial de la patología cardiorrespiratoria en la edad pediátrica.
The congenital portosystemic shunt is an uncommon disease with severe complications if not treated. This rare cause of hypoxemia was first described by John Abernethy in 1973. There are two types: type I (termino-lateral shunt), in which there is total absence of the intrahepatic portal flow, and type II (latero-lateral shunt), in which the portal flow is partially preserved. We present the case of a 6-year-old girl with chronic hypoxemia history since 4 and a half years of age, showing progressive dyspnea, who was referred to the Pediatric Pulmonary Division with the diagnosis of central cyanosis. An Echo-Doppler in the portal venous system was performed, reporting agenesis of the principal portal vein. This finding was corroborated by an angiography of the portal and mesenteric arteriovenous system. The study was completed with a portosplenography, which confirmed the diagnosis of type Ib Abernethy malformation. The type I Abernethy malformation is more common in females, shows up in different ways and is treated with liver transplantation. On the other hand, type II Abernethy malformation shows a variable portal circulation and has a better prognosis than type I. Dyspnea when exercising and central cyanosis should be considered to make a differential diagnosis of cardiorespiratory disease at a pediatric age.

Portosystemic shunts are rare vascularization disorders, and an uncommon cause of confusional states. We report an 87-year-old male with a previously normal cognitive status who was repeatedly admitted for sudden symptoms of disorientation and functional limitation. The patient had high ammonium levels which lead to the suspicion of the presence a portosystemic shunt, even in the absence of pre-existing liver disease. A contrast enhanced computed tomography of the abdomen confirmed the presence an abnormal communication of the right portal vein with the suprahepatic veins. The communication was embolized and the confusional states of the patient subsided.

Abstract Objective: To report a patient with prenatal diagnosis of portosystemic shunt; a rare condition in humans. Case description: 17-Day-old female infant admitted for investigation of suspected diagnosis of portosystemic shunt, presumed in obstetric ultrasound. The hypothesis was confirmed after abdominal angiography and liver Doppler. Other tests such as echocardiography and electroencephalogram were performed to investigate possible co-morbidities or associated complications, and were normal. We chose conservative shunt treatment, as there were no disease-related complications and this was intrahepatic shunt, which could close spontaneously by the age of 2 years. Comments: Portosystemic shunt can lead to various complications such as hepatic encephalopathy, hypergalactosemia, liver tumors, and hepatopulmonary syndrome. Most diagnoses are done after one month of age, after such complications occur. The prenatal diagnosis of this patient provided greater security for the clinical picture management, as well as regular monitoring, which allows the anticipation of possible complications and perform interventional procedures when needed.
Resumo Objetivo: Descrever a história clínica de paciente com diagnóstico pré-natal de shunt portossistêmico, condição rara na espécie humana. Descrição do caso: Recém-nascido do sexo feminino internada aos 17 dias para investigação de suspeita diagnóstica de shunt portossistêmico, aventada na ecografia obstétrica. A hipótese foi confirmada após angiotomografia do abdome e ecodoppler hepático. Outros exames, como ecocardiograma e eletroencefalograma, foram feitos para investigação de possíveis comorbidades ou complicações associadas e tiveram resultados normais. Optou-se por tratamento conservador do shunt, já que não havia quaisquer complicações relacionadas à doença e tratava-se de shunt intra-hepático, que pode fechar espontaneamente até os dois anos de idade. Comentários: O shunt portossistêmico pode levar a diversas complicações, como encefalopatia hepática, hipergalactosemia, tumores hepáticos e síndrome hepatopulmonar. A maioria dos diagnósticos é feita a partir de um mês de vida, após tais complicações ocorrerem. O diagnóstico pré-natal dessa paciente possibilitou maior segurança para o manejo do quadro, bem como um acompanhamento periódico que permite antecipar possíveis complicações e adotar conduta intervencionista, se necessário.

La ausencia congénita de la vena porta hepática es una malformación en extremo rara, fue descrita por primera vez en 1793 por John Abernethy y a la fecha se han reportado sólo 101 casos. Afecta con mayor frecuencia a mujeres y determina que el drenaje venoso intestinal sea derivado hacia el territorio de las venas sistémicas. Es también conocida como derivación porto-sistémica extra hepática congénita (CEPS), por su sigla en inglés, y se asocia a otras alteraciones congénitas,incluyendo anomalías cardíacas, de las vías biliares, enfermedades metabólicas y retardo mental. En este trabajo presentamos el hallazgo de esta malformación en el cadáver de un niño de dos años de edad, donde la vena porta seguía un trayecto anómalo y se unía a la vena renal derecha. El confluente venoso "mesentérico-esplénico-renal" así formado presentaba un trayecto descendente, recibía a la vena gonadal derecha, y desembocando en la confluencia de las venas ilíacas comunes. Esto se asociaba a mal rotación intestinal, arteria hepática aberrante y a vena cava inferior izquierda, situación descrita sólo una vez en la literatura. El hallazgo de estas anomalías anatómicas en los cadáveres disecados con fines docentes en nuestro Departamento de Anatomía, tiene un valor formativo indiscutible para nuestros alumnos de pre y postgrado, quienes pueden valorar las implicancias de este conocimiento anatómico en la clínica diaria.
Congenital absence of the hepatic portal vein is an extremely rare malformation that was first described by John Abernethy in 1793. Only 101 cases had been described in the literature until 2015 and most affected females. In this anomaly, also known as congenital extrahepatic porto-systemic shunt (CEPS), intestinal venous drainage is derived towards the territory of the systemic veins and could be associated with other birth defects, including heart and biliary tract anomalies, metabolic diseases, mental retardation. We present the case of a 2-year-old boy who died because of multifocal pneumonia and necropsy showed anatomical findings consistent with this malformation as an incidental finding. The portal vein followed an anomalous course and joined the right renal vein, forming the "mesenteric-splenic-renal" venous collector, which then received the right gonadal vein and ended at the confluence of the common iliac veins. In our case this anomaly was associated to intestinal malrotation, aberrant hepatic artery and persistent left inferior vena cava, situation described once in the literature. The finding of these anatomical abnormalities in cadavers has a great teaching value for our undergraduate and graduate students who are learning anatomy and they can also assess the associated clinical.

The morphometry and haemodynamic aspects of portal vein were studied in 20 normal dogs with less than 120 days of age and in 14 dogs presenting portosystemic shunting with ages between 90 and 360 days. In the control group the hepatic margins were seen 1.50cm to 3.00cm caudal to the costal margin. Collected data indicated that the mean diameter of portal vein (VP), caudal vena cava (VCC) and abdominal aorta (AO) measured respectively, 0.38cm, 0.37cm and 0.41cm. The VP/VCC and VP/AO mean ratios were respectively, 1.10 and 0.94. The average of VP, VCC and AO areas were respectively, 0.12cm², 0.11cm² and 0.14cm². The haemodynamic of portal vein was studied by ultrasound Doppler and the mean velocity of portal blood flow (VMFSP) measured was 17.76cm/s. It was verified that portal blood flow (FSP) average was 83.11ml/min/kg and the congestion index (IC) average was 0.006. In the group of animals presenting portosystemic shunting, the hepatic margins were seen 1.00cm to 2.00cm cranial to the costal margin. The morphometry of VP, VCC and AO presented a mean diameter of 0.40cm, 0.74cm and 0.56cm, respectively. The VP/VCC and VP/AO mean ratios were respectively, 0.54 and 0.69. The average of VP, VCC and AO areas were respectively, 0.14cm², 0.31cm² and 0.25cm². The haemodynamic study demonstrated that the VMFSP measured was 22.29cm/s and the IC average was 0.006.
Foram realizados o estudo morfométrico e o estudo hemodinâmico da veia porta em vinte cães clinicamente normais, de idade igual e inferior a 120 dias e em quatorze cães portadores de shunt portossistêmico, de idades entre 90 e 360 dias. Nos cães do grupo controle, as margens hepáticas apresentaram-se entre 1,50cm e 3,00cm caudalmente à margem costal. Os diâmetros médios da veia porta (VP), veia cava caudal (VCC) e aorta abdominal (AO) obtidas foram respectivamente, 0,38cm, 0,37cm e 0,41cm. As proporções entre os diâmetros médios VP/VCC e VP/AO apresentaram médias de 1,10 e 0,94, respectivamente. As médias das áreas da VP, VCC e AO resultaram respectivamente em 0,12cm² , 0,11cm² e 0,14cm². No estudo hemodinâmico da VP destes animais, utilizando-se o ultrassom Doppler, a velocidade média de fluxo sangüíneo portal (VMFSP) mediu 17,76cm/s. A média de fluxo sangüíneo portal (FSP) resultou em 83,11ml/min/kg. O índice de congestão (IC) apresentou média de 0,006. Para o grupo de cães portadores de shunt portossistêmico, o fígado apresentou redução de seu volume, sendo as margens hepáticas visibilizadas entre 1,00cm e 2,00cm cranialmente à margem costal. No estudo morfométrico, as médias dos diâmetros médios obtidos de VP, VCC e AO resultaram respectivamente em 0,40cm, 0,74cm e 0,56cm. As proporções entre os diâmetros médios VP/VCC e VP/AO resultaram respectivamente em 0,54 e 0,69. As médias das áreas de VP, VCC e AO resultaram respectivamente em 0,14cm², 0,31cm² e 0,25cm². Ao ultrassom Doppler a VMFSP mediu 22,29cm/s e a média do IC da VP obtido foi de 0,006.

La cavernomatosis portal es una patología poco frecuente causada por la trombosis de la vena porta. Es la principal causa de hipertensión portal en niños. La causa muchas veces no se identifica, pudiendo reconocerse factores predisponentes, entre los cuales los más frecuentes son el cateterismo de la vena umbilical y la onfalitis. Se manifiesta a través de sus complicaciones: hemorragia digestiva alta por várices esofágicas y esplenomegalia. El diagnóstico se confirma con ecografía abdominalcon Doppler. La terapéutica incluye el tratamiento médico-endoscópico de las várices esofágicas. La derivación quirúrgica porto-sistémica resuelve la obstrucción portal. Se realizó un estudio retrospectivo con el objetivo de describir las características clínicas de pacientes con cavernomatosis portal en el período enero de 1999 a abril de 2009 en el Hospital Pediátrico del Centro Hospitalario Pereira Rossell (HP-CHPR). Se identificaron ocho pacientes, con una media de edad al momento del diagnóstico de 2 años y 2 meses. La forma de presentación más frecuente fue la hematemesis. En la mayoría se constató esplenomegalia. En tres se identificaron factores predisponentes: cateterismo umbilical, cirugía abdominal. Todos tenían várices esofágicas al diagnóstico. Tres pacientes reiteraron hemorragia digestiva alta, uno en tres y otro en cuatro oportunidades. Cuatro pacientes requirieron escleroterapia o banding por sus várices esofágicas. Un paciente recibió cirugía derivativa. Esta patología no tuvo, en este período de tiempo, una alta prevalencia, pero alta morbilidad. Todos eran pequeños, la mayoría sin factores de riesgo y se presentaron a través de complicaciones de la enfermedad. La mayoría reiteró complicaciones en la evolución.

BACKGROUND AND OBJECTIVES: Hepatic infarction is characterized by parenchyma ischemic necrosis involving at least two acinis. It is extremely uncommon due to the arterial and portal venous blood supply. We report a case of a patient not know to have diabetes who developed massive areas of ischemic infarcts of the liver after episode of acutely diabetes decompensated.

Abdominal situs inversus is a rare condition usually associated with malformations of asymmetric organs such as the heart, liver, spleen and malrotation of the intestines. A case of abdominal situs inversus with intestinal malrotation and preduodenal portal vein is reported. Patient underwent prophylactic Ladd's procedure and preduodenal portal vein was left undisturbed during surgery. This case highlights the importance of rigorous investigation of anatomic features prior to surgery in a patient with heterotaxia. The authors advocate radiological investigation of patients with heterotaxia and prophylactic Ladd's procedure in those with intestinal malrotation.
