Abstract
Congenital portosystemic shunts (CPSSs) are rare vascular anomalies characterized by abnormal connections between the portal/splanchnic veins and the systemic veins. CPSSs often occur as an isolated congenital anomaly, but they can also coexist with congenital heart disease (CHD). Owing to their myriad consequences on multiple organ systems, familiarity with CPSS is of tremendous importance to the care of patients with CHD. The rationale and timing for interventions to embolize CPSS in this scenario are discussed. Specific shunt embolization techniques are beyond the scope of this article.

Abstract
BACKGROUND Congenital portosystemic shunts (CPSS) are rare congenital abnormalities causing abnormal blood flow between the portal vein and systemic circulation. This study reports on the peri-operative anticoagulation management of CPSS patients post closure, focusing on the incidence of thrombotic and bleeding complications. METHODS This is a single-center retrospective analysis of CPSS patients who underwent surgery or endovascular intervention between 2005 and 2021. The protocol included unfractionated heparin (UFH) during and immediately after surgery, followed by either warfarin or low molecular weight heparin (LMWH) postoperatively. Outcomes assessed included postoperative thrombotic and bleeding complications. RESULTS A total of 44 patients were included. Postoperatively, 89% received treatment-dose UFH, transitioning to warfarin or LMWH at discharge. Thrombotic complications occurred in 16% of patients, predominantly in the superior mesenteric vein. Surgical interventions and continuous infusion of tissue plasminogen activator (tPA) were used for clot resolution. Bleeding complications were observed in 64% of patients, primarily managed with transfusions and temporary UFH interruption. No deaths related to thrombotic, or bleeding events were reported. CONCLUSIONS Our findings underscore the delicate balance required in anticoagulation management for CPSS patients, revealing an occurrence of both thrombotic and bleeding complications postoperatively. LEVELS OF EVIDENCE Level II, retrospective study.

Abstract
Congenital portosystemic shunts are rare vascular malformations in which portal venous blood from the intestines and spleen bypasses the liver and diverts directly into the systemic circulation through abnormal vessels. We report a case of a 4-year-old girl with heterotaxy syndrome, polysplenia, and situs inversus presenting with persistent hypoxemia who was found to have pulmonary arteriovenous malformations (PAVMs) and hypoxemia secondary to a congenital portosystemic shunt. Management of this patient's PAVMs involved endovascular occlusion of the portosystemic shunt with subsequent resolution of hypoxemia. PAVMs secondary to extrahepatic portosystemic shunt should be explored as a cause of progressive cyanosis in children with heterotaxy, polysplenia, and interrupted inferior vena cava with azygous continuation.

Abstract
Congenital portosystemic shunt (CPS) is a rare vascular anomaly resulting in diversion of splanchnic or portal blood into the systemic circulation. Other vascular malformations associated with this entity are uncommon. A 4-year-old female child with a diagnosis of acute viral hepatitis had an incidental finding of extrahepatic CPS on a Doppler abdominal ultrasound. Contrast-enhanced computed tomography showed a dilated portal vein having H-type side-to-side communication with a hypoplastic intrahepatic portion of the inferior vena cava and a prominent dilated azygos vein. There was retroaortic left renal vein drained into the IVC which was visualized in its entirety. Echocardiography findings were normal and the patient was discharged after symptomatic treatment that achieved improvement. With the expansion of abdominal imaging, incidental cases of CPS are increasingly being diagnosed in children. Although vascular malformations associated with CPS are rare, early diagnosis of cases helps avoid complications during shunt closure.

Abstract
Congenital intrahepatic portosystemic venous shunt (CPSVS), a rare vascular malformation, has been described in both children and adults and can lead to severe neurophysiological complications. However, a standard therapeutic protocol for CPSVS has not been elucidated. With the advantage of minimally invasive techniques, transcatheter embolization has been used to treat CPSVS. The condition is challenging to manage, especially in patients with large or multiple shunts, through which rapid blood flow can cause ectopic embolism. Here, we describe a case of CPSVS with a large shunt that was successfully treated with balloon-occluded retrograde transvenous obliteration with interlocking detachable coils.

Abstract
INTRODUCTION Umbilical-portal-systemic venous shunts (UPSVS) are rare anomalies in the development of the fetal venous system. There are several postnatal and prenatal classifications of hepatic venous anomalies but the link between them is missing. We aimed to review the prenatal to postnatal diagnosis correlation in UPSVS at our center. METHODS It is a retrospective study of patients diagnosed with UPSVS between 2019 and 2021 at our institution. Demographic, obstetric, genetic, and neonatal data were reviewed with special focus on prenatal and postnatal ultrasounds. RESULTS A total of seven patients were diagnosed with UPSVS at a median of 24 (20-34) weeks of gestational age. All patients were male and 62% were Caucasian. None of the patients had chromosomopathies or cardiac anomalies. One patient had renal ectopia, another one had a single umbilical artery, and a third one suffered from intrauterine growth retardation. An umbilico-systemic shunt (USS) was found in two patients and a ductus venosus-systemic shunt (DVSS) in the rest. Patients with USS were diagnosed postnatally with intrahepatic portosystemic shunts. One of the DVSS patients was transferred to another hospital and the other four had normal postnatal cardiac ultrasounds, with normal abdominal ultrasounds in two patients and lack of postnatally abdominal control in the other two. All babies were found to be doing well at a median follow-up of 1 month (0-24). CONCLUSION There is a knowledge gap in the natural history of UPSVS between fetal and neonatal life. Building bridges between prenatal and postnatal research is mandatory in order to understand these rare anomalies.

Abstract
Congenital portosystemic shunts (CPSS) are rare vascular anomalies that cause abnormal communications between the portal and systemic venous systems and may be incidentally detected on imaging or via abnormal laboratory parameters due to the lack of specificity in the condition's clinical presentation. Ultrasound (US) is a common tool for examining abdominal solid organs and vessels and is the initial imaging modality for diagnosing CPSS. Here we report the case of an 8-year-old Chinese boy with CPSS diagnosed using color Doppler US. Doppler US first found intrahepatic tumor, then revealed that the left portal vein was directly communicating with the inferior vena cava, and the boy was finally diagnosed with intrahepatic portosystemic shunts. Interventional therapy was employed to occlude the shunt. During the follow-up, the intrahepatic tumor disappeared and no complications. Hence, to be able to differentiate such vascular anomalies, clinicians should be fairly acquainted with the normal ultrasonographic anatomical features in daily clinical work. Furthermore, increased disease awareness and advances in imaging equipment and technology are essential for CPSS diagnosis.

Abstract
BACKGROUND Recent advances in fetal ultrasound imaging, especially four-dimensional (4D) spatio-temporal image correlation techniques permit detailed evaluation of the fetal venous system and its abnormalities. In this report, we present the clinical presentation, conventional/4D spatio-temporal image correlation imaging findings, pregnancy, and early postnatal outcomes in fetuses having anomalies of systemic venous return in the absence of significant intracardiac defects from two centres in southern India. OBJECTIVES To report the clinical presentation, conventional/4D spatio-temporal image correlation imaging findings, pregnancy, and early postnatal outcomes in fetuses having anomalies of systemic venous return in the absence of significant intracardiac defects from two centres in Southern India. METHODS Retrospective study (October 2017 to March 2022). All fetuses referred with abnormal cardiac imaging findings who were diagnosed to have anomalies of systemic venous return in the absence of significant intracardiac defects were included. Imaging techniques like 2D with color and 4D spatio-temporal image correlation fetal imaging were used to evaluate systemic venous anomalies. Systemic venous anomalies were grouped into cardinal venous anomalies and umbilico-portosystemic venous anomalies. RESULTS Thirty-nine fetuses were included; this represented 4.4% of all cardiac anomalies diagnosed during the study period. Cardinal venous anomalies were seen in 29 fetuses (74%); the mean gestation age at diagnosis was 25.5 ± 3.4 weeks. Absent dilated coronary sinus was associated with anomalous drainage of superior caval vein through completely unroofed coronary sinus into the left atrium (n = 3) which resulted in cyanosis after birth in all infants. Among the three cases, one underwent surgery at 6 months of age due to a progressive increase in cyanosis (Spo2 78%) and others are awaiting surgery. A prenatal genetic evaluation was performed in 17 (58.6%). Cardinal venous anomalies were not associated with genetic abnormalities. Live births occurred in all fetuses with cardinal venous anomalies. Umbilico-portosystemic venous anomalies were seen in 10 (26%). The mean gestation age at diagnosis was 26.5 ± 4.5 weeks. Except in a fetus with the extrahepatic portosystemic shunt (umbilical vein to iliac vein), the genetic evaluation was normal in our cohort. Extracardiac anomalies (n = 3/10; 30%) were seen in both intra (n = 1) and extrahepatic portosystemic shunts (n = 2). CONCLUSION Anomalies of systemic venous return in the absence of significant intracardiac, extracardiac, and genetic abnormalities carried an overall favorable prognosis in our cohort. Precise characterization of anatomic details using advanced imaging techniques helps in the understanding of this complex three-dimensional anatomy and in the prognostication of these anomalies.

Abstract
Background To investigate the prenatal ultrasonographic features and case characteristics of the congenital intrahepatic portosystemic venous shunt (IHPSS) diagnosed during the foetal period and analyse its prognosis. Methods We conducted a retrospective cohort study of patients diagnosed with IHPSS between 2016 and 2021. IHPSS was defined as an abnormal connection between the foetal intrahepatic portal and the hepatic veins. Results In this study, 19 foetuses were identified, including 12 cases of single shunt and 7 cases of multiple shunts, with a gestational age of 33.8 ± 4.5 (range 25–40) weeks at diagnosis. In the single-shunt group, the origin position of the shunts was all from the left branch of the portal vein (LPV), whereas in the multiple-shunt group, the origin position of the shunts was from the LPV in six cases. Common concomitant intrauterine abnormalities of IHPSS include foetal growth restriction (47.4%) and foetal cardiac enlargement (21.1%). The postnatal manifestations of IHPSS include biochemical abnormalities (increased gamma-glutamyl transferase and bilirubin levels), neonatal hypoglycaemia, neonatal hyperammonaemia, pulmonary hypertension, multiple intrahepatic hyperechoic nodules, and cutaneous haemangiomas. Spontaneous closure of shunts occurred in ten cases, and the mean time to shunt closure was 8.1 months (1–28 months). Conclusions Most IHPSS found during the foetal period is located in the left branch of the portal vein, and the gestational age at diagnosis is usually in the late second or third trimester. Spontaneous closure of shunts can occur in most live births, and the prognosis is good.

Abstract
Background Congenital portosystemic shunts (CPSS) are rare vascular malformations associated with the risk of life-threatening systemic conditions, which remain underdiagnosed and often are identified after considerable diagnostic delay. CPSS are characterized by multiple signs and symptoms, often masquerading as other conditions, progressing over time if the shunt remains patent. Which patients will benefit from shunt closure remains to be clarified, as does the timing and method of closure. In addition, the etiology and pathophysiology of CPSS are both unknowns. This rare disorder needs the strength of numbers to answer these questions, which is the purpose of the international registry of CPSS (IRCPSS). Method A retrospective and prospective registry was designed using secuTrial® by the ISO certified Clinical Research Unit. Given that a significant number of cases entered in the registry are retrospective, participants have the opportunity to use a semi-structured minimal or complete data set to facilitate data entry. In addition, the design allows subjects to be entered into the IRCPSS according to clinically relevant events. Emphasis is on longitudinal follow-up of signs and symptoms, which is paramount to garner clinically relevant information to eventually orient patient management. The IRCPSS includes also three specific forms to capture essential radiological, surgical, and cardiopulmonary data as many times as relevant, which are completed by the specialists themselves. Finally, connecting the clinical data registry with a safe image repository, using state-of-the-art pseudonymization software, was another major focus of development. Data quality and stewardship is ensured by a steering committee. All centers participating in the IRCPSS have signed a memorandum of understanding and obtained their own ethical approval. Conclusion Through state-of-the-art management of data and imaging, we have developed a practical, user-friendly, international registry to study CPSS in neonates, children, and adults. Via this multicenter and international effort, we will be ready to answer meaningful and urgent questions regarding the management of patients with CPSS, a condition often ridden with significant diagnostic delay contributing to a severe clinical course.

Abstract
OBJECTIVE Congenital intrahepatic shunts divert highly oxygen and nutrients rich placental blood flow from the liver into the systemic flow having a negative influence on normal fetal growth and postnatal development. The ability to recognize this anomaly helps assess the possible clinical impact, counseling, and management of pregnancy. The present study aimed to propose in utero classification for the Intrahepatic Umbilical-Porto-Systemic Venous Shunt (IHUPSVS) based on our experience. STUDY DESIGN A prospective study. Grayscale ultrasound with two and three-dimensional high-definition Doppler modalities was used. IHUPSVS was defined as a diversion of blood from the liver tissue by abnormal communication between a branch of the intrahepatic Umbilical vein or the Portal veins with the systemic circulation (the Hepatic veins or the Sub-Diaphragmatic Vestibulum). RESULTS Twenty-five fetuses were diagnosed with IHUPSVS. We identified three main anatomic types: I) Porto-hepatic shunt which was divided into Ia) regular single shunt (15/25, 60%) and Ib) regular multiple shunts, (6/25, 24%) II) Umbilical-Porto-Hepatic shunt divided into a) Umbilical or b) Umbilical combined with Portal hepatic shunt (2/25, 8%) and III) Cavernous- aneurysmatic shunt (2/25, 8%). All the shunts were verified by postnatal targeted sonography. CONCLUSIONS This study creates the anatomic basis for common nomenclature and future probable updating for this anomaly.

Abstract
Background 22q11.2 deletion syndrome (22qDS) is the most common chromosomal microdeletion syndrome and is associated with a high rate of congenital heart disease (CHD) and neurodevelopmental abnormalities. Congenital portosystemic venous shunts (CPSS) are rare developmental abnormalities of the portal venous system. The clinical manifestations of CPSS are varied, and some patients have CHD or genetic chromosomal abnormalities, but their relationship remains unknown. We report the first case of CPSS associated with 22qDS. Case presentation A newborn boy referred to our institution was diagnosed with 22qDS due to characteristic facial features and complications of tetralogy of Fallot. A subsequent newborn screening test indicated hypergalactosemia and high blood levels of ammonia and bile acids. Upon closer examination, these abnormalities were found to be caused by the CPSS. Abdominal contrast-enhanced computed tomography and angiography confirmed that abnormal blood vessels ascended from the splenic vein and short-circuited to the left renal vein. Intracardiac repair for CHD was performed at 1 year of age, followed by transcatheter occlusion of the CPSS using a multilayer device (vascular plug) and detachable coil at 2 years of age. After treatment, the abnormal blood parameters promptly normalized. Conclusions As the blood flow of CPSS bypasses the liver, the levels of galactose, bile acids, and ammonia in the systemic veins can increase. Some patients with CPSS have CHD, and these toxic substances may cause liver and lung lesions as well as portosystemic encephalopathy (PSE). Several genetic chromosomal abnormalities, including 22qDS, and CPSS have similar symptoms, and neurodevelopmental abnormalities, particularly those caused by PSE, may be difficult to diagnose. Blood tests, such as newborn screening, and abdominal imaging are useful in the early diagnosis of CPSS.

Abstract
The fetal circulation is characterized by the presence of three physiological vascular shunts - the ductus arteriosus, the foramen ovale and the ductus venosus. Acting in concert, these shunts preferentially stream blood flow in a pattern that maximizes efficiency of blood oxygenation by the maternofetal unit. Shortly following the transition to extrauterine life, a quick and predetermined succession of events results in closure of these embryological structures with consequent establishment of postnatal vascular flow patterns. While this transition is often seamless, the physiological shunts of the fetus occasionally fail to regress. Such failure to regress can occur in isolation or in association with other congenital malformations. This failed regression challenges the circulatory physiology of the neonate and might have implications for the optimum functioning of several organ systems. When symptomatic, these shunts are treated. Interventions, when undertaken, might be medical, endovascular or surgical. The radiologist's role continues to expand in the assessment of these shunts, in providing a roadmap for treatment and in prompt identification of treatment-related complications. This review is to familiarize radiologists with the embryology, pre- and post-treatment imaging appearances, and associated complications of persistent fetal vascular shunts.

Abstract
CASE HISTORY A 1-year-old Border Terrier presented with acute onset of neurological signs and neck pain. CLINICAL FINDINGS Severe generalised ataxia, muscle tremors and cranial nerve deficits were noted. Multifocal brain lesions were suspected based on neurological examination. Computed tomography revealed an abdominal mass and cerebellar herniation through the foramen magnum. LABORATORY AND PATHOLOGICAL FINDINGS Cytological and histopathological analysis of the abdominal mass revealed necrotising and granulomatous lymphadenitis with intralesional algal elements most consistent with Prototheca spp.. Culture of a sample from the mesenteric lymph node confirmed the presence of Prototheca spp. which was identified as P. bovis based on sequencing of a DNA fragment amplified by PCR. Following inadequate response to symptomatic therapy and poor prognosis, the dog was subjected to euthanasia. Histopathological evaluation of the central nervous system lesions, identified granulomatous meningitis and ventriculitis with the presence of intralesional algae. DIAGNOSIS Disseminated protothecosis with granulomatous meningitis and ventriculitis caused by Prototheca bovis (formerly P. zopfii gen. 2). CLINICAL RELEVANCE This is the first case report of disseminated protothecosis with central nervous system involvement in a dog in New Zealand.

Abstract
Background: Congenital portosystemic shunts (CPSS) are rare vascular anomalies resulting in communications between the portal venous system and the systemic venous circulation, affecting an estimated 30,000 to 50,000 live births. CPSS can present at any age as a multi-system disease of variable severity mimicking both common and rare pediatric conditions. Case presentations: Case A: A vascular malformation was identified in the liver of a 10-year-old girl with tall stature, advanced somatic maturation, insulin resistance with hyperinsulinemia, hyperandrogenemia and transient hematuria. Work-up also suggested elevated pulmonary pressures. Case B: A young girl with trisomy 8 mosaicism with a history of neonatal hypoglycemia, transient neonatal cholestasis and tall stature presented newly increased aminotransferase levels at 6 years of age. Case C: A 3-year-old boy with speech delay, tall stature and abdominal pain underwent abdominal ultrasound (US) showing multiple liver nodules, diagnosed as liver hemangiomas by hepatic magnetic resonance imaging (MRI). Management and outcome: After identification of a venous malformation on liver Doppler US, all three patients were referred to a specialized liver center for further work-up within 12 to 18 months from diagnosis. Angio-computed tomography (CT) scan confirmed the presence of either an intrahepatic or extrahepatic CPSS with multiples liver nodules. All three had a hyperintense signal in the globus pallidus on T1 weighted cerebral MRI. Right heart catheterization confirmed pulmonary hypertension in cases A and C. Shunts were closed either using an endovascular or surgical approach. Liver nodules were either surgically removed if there was a risk of malignant degeneration or closely monitored by serial imaging when benign. Conclusion: These cases illustrate most of the common chief complaints and manifestations of CPSS. Liver Doppler US is the key to diagnosis. Considering portosystemic shunts in the diagnostic work-up of a patient with unexplained endocrine, liver, gastro-intestinal, cardiovascular, hematological, renal or neurocognitive disorder is important as prompt referral to a specialized center may significantly impact patient outcome.

Abstract
Fatty acid oxidation defects (FAOD) and urea cycle defects (UCD) are among the most common metabolic liver diseases. Management of these disorders is dotted with challenges as the strategies differ based on the type and severity of the defect. In those with FAOD the cornerstone of management is avoiding hypoglycemia which in turn prevents the triggering of fatty acid oxidation. In this review, we discuss the role of carnitine supplementation, dietary interventions, newer therapies like triheptanoin, long-term treatment and approach to positive newborn screening. In UCD the general goal is to avoid excessive protein intake and indigenous protein breakdown. However, one size does not fit all and striking the right balance between avoiding hyperammonemia and preventing deficiencies of essential nutrients is a formidable task. Practical issues during the acute presentation including differential diagnosis of hyperammonemia, dietary dilemmas, the role of liver transplantation, management of the asymptomatic individual and monitoring are described in detail. A multi-disciplinary team consisting of hepatologists, metabolic specialists and dieticians is required for optimum management and improvement in quality of life for these patients.

Abstract
Abernethy malformation is a rare abnormality of the hepatic portal vein system with non-specific and diverse clinical manifestations. Here, we described a case of abernethy malformation with hepatopulmonary syndrome in a 10-year-old girl. On physical examination, cyanosed lips and acropachy could be found. Her oxygen saturation fluctuated at 89-94%, and the fasting blood ammonia was 98 umol/L. Furthermore, there were abnormalities in the imaging. The microbubble test with contrast echocardiography was positive. Computer tomography angiography (CTA) showed the splenic vein, and the superior mesenteric drained directly into the inferior vena cave after confluence. The same result was also observed in delayed splenic arteriography. Then, we discovered a tiny branch of the intrahepatic portal vein by the inferior vena cava balloon occlusion test, which could also show the confluence of the splenic vein and superior mesenteric vein with the inferior venacave. According to the evidence above, we concluded that the girl was a patient of type II abernethy malformation. For the severe dysplasia of the portal vein, the girl accepted partial ligation of portosystemic shunt and Rex shunt, which improved her oxygen saturation and exercise tolerance.

JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2021; 40:2431-2439. [PMID: 33426710 DOI: 10.1002/jum.15629] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Revised: 12/17/2020] [Accepted: 12/29/2020] [Indexed: 06/12/2023]
Abstract
OBJECTIVES Congenital portosystemic shunt (CPSS) in a growth-restricted fetus may lead to cardiac overload and ultimately hemodynamic imbalance. The aim of the study was to describe the application of tricuspid annular plane systolic excursion (TAPSE) for surveillance of cardiac function in growth-restricted fetuses diagnosed with CPSS. METHODS The study group consisted of 7 fetuses with growth restriction diagnosed with CPSS between 2018 and 2020. Patients were followed longitudinally every 2 weeks. Sonographic fetal-TAPSE (f-TAPSE) was performed every 2 weeks. At each visit, the following parameters were recorded: estimated fetal weight, biophysical profile, nonstress test, Doppler flow indices, and fetal cardiothoracic index. Postnatal laboratory and imaging tests were retrieved from the medical files. RESULTS Mean gestational age at diagnosis of CPSS was 32 + 1 weeks. Cardiomegaly was observed in all cases. All portosystemic shunts were classified as intrahepatic. Values of f-TAPSE were above the 95th percentile in 6/7 fetuses at presentation and throughout follow-up. Gestational age at delivery ranged between 36 + 5 and 38 + 5 weeks. Postnatally, spontaneous closure of the shunt was noted in 2 infants. Transient hyperammonemia was diagnosed in 2 neonates, with no signs of the characteristic complication. CONCLUSIONS In growth-restricted fetuses diagnosed concomitantly with CPSS, f-TAPSE offers a practical sonographic tool for assessment of cardiac function and may serve as an additional clinical marker for follow-up. The appearance of cardiomegaly in growth-restricted fetuses should prompt a dedicated sonographic evaluation of the fetal portal system.

Abstract
Congenital intrahepatic portosystemic shunts are rare vascular malformations in which abnormal communications are created between the portal veins and the hepatic veins or the inferior vena cava system. Diagnosis is made by prenatal or postpartum ultrasound. Published data regarding presentation, symptoms, and prognosis is scarce. This study aimed to better understand the natural history and the course of the intrahepatic portosystemic shunts. Data were collected from children in two medical centers who were diagnosed with congenital intrahepatic portosystemic shunts on either prenatal or postnatal sonographic screening. The subjects' medical information was collected including demographics, medical background, and sonographic and clinical outcome. Blood test results including ammonia levels and liver function tests were documented, as well as the sonographic dimensions of the shunt vessels and the spleen size. The data were analyzed using various statistical methods. Twenty-three children with portosystemic shunts were found and reviewed. Eight children were excluded from the study since records and follow-up were insufficient. Fifteen patients were included in the study (six females). All had intrahepatic shunt diagnosed either by prenatal screening or postnatal abdominal ultrasound and had more than one ultrasound and repeated blood tests. Shunt closure was observed in all children within a mean of 114.31 ± 115.05 days (median 84). There was no correlation between liver enzymes, ammonia, and ultrasound vascular and splenic diameters to time to closure. None of the children had any hepatic or other sequelae.Conclusions: Our study suggests that congenital intrahepatic portosystemic shunt is a benign, self-limiting condition in which no correlation between the size of the shunt and the blood ammonia level to the outcome of the shunt was found. This is the first study that correlated radiological measures to the outcome. These results suggest that the treating physician should reassure families and conduct minimal follow-up and interventions in children with such conditions. Further, larger and prospective studies should be done to corroborate these conclusions. What is Known: • Characteristics and natural history of intrahepatic portosystemic shunts are less defined. • The natural course of the intrahepatic malformations varies, but spontaneous, self-resolution of small shunts, usually occures within 1 to 2 years. What is New: • In this study, congenital intrahepatic portosystemic shunt was shown to be benign, self-limiting condition in which all shunts closed within 3 months. • No correlation between the size of the shunt and the blood ammonia level to the outcome of the shunt was found.

Abstract
The aim of this retrospective study was to investigate the clinical characteristics and therapeutic outcomes of pulmonary arterial hypertension (PAH) secondary to congenital portosystemic shunts (CPSS). Thirty-three pediatric patients diagnosed in our institution with CPSS between 2012 and 2019 were enrolled in this study. The patients were divided into PAH and non-PAH groups. The PAH group included 15 patients who presented with unexplained PAH when CPSS was diagnosed. Two patients with microangiopathic hemolytic anemia died of right heart failure shortly after diagnosis. One patient received a liver transplant at the age of 4.3 years and showed a mild decrease in pulmonary artery pressure (PAP) 4 years after the operation. Seven patients underwent one-stage shunt closure at a median age of 2.8 years (1.4-13 years). Follow-up examinations, from 1.6 to 4.1 years after intervention, showed marked reduction of PAP in one patient and stabilization of PAH in six others. However, in one patient who underwent two-stage shunt closure, a marked increase in PAP was noted after partial ligation of the shunt. The remaining four patients received only pulmonary vasodilator therapy, and one of them died of right heart failure 12 years after the PAH diagnosis. The non-PAH group included 18 patients without evidence of PAH upon CPSS diagnosis. Shunt closure was carried out in eight of these patients, but one patient subsequently developed PAH after the resolution of hepatopulmonary syndrome.Conclusion: CPSS may be a more likely cause of unexplained PAH in pediatric patients than previously thought. Shunt closure or liver transplantation may prevent the progression of PAH, or even improve it for the majority of CPSS patients.

Outcome of paediatric portopulmonary hypertension in the modern management era: A case report of 6 patients. J Hepatol 2021; 74:742-747. [PMID: 33276028 DOI: 10.1016/j.jhep.2020.11.039] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Revised: 10/25/2020] [Accepted: 11/16/2020] [Indexed: 12/30/2022]
Abstract
Portopulmonary hypertension is a rare but serious complication of portal hypertension or portosystemic shunting. Portopulmonary hypertension is an indication for liver transplantation or shunt closure. However, liver transplantation is contraindicated in patients with severe pulmonary arterial hypertension. Reported mortality rates are high in children with portopulmonary hypertension and there are scarce recommendations on its management. Our aim was to report on our real-world experience of managing portopulmonary hypertension in a specialised centre. We describe a series of 6 children with portopulmonary hypertension. Their median age at diagnosis was 13 years (range 10-15). The underlying liver conditions were cirrhosis of unknown origin (1), congenital portocaval shunts (3), biliary atresia (1), and portal vein cavernoma with surgical mesenterico-caval shunt (1). Median mean pulmonary arterial pressure was 47 mmHg (range 32-70), and median pulmonary vascular resistance was 6.6 Wood units (range 4.3-15.4). All patients except one were treated with a combination of pulmonary arterial hypertension-specific therapy (phosphodiesterase type 5 inhibitors and/or endothelin receptor antagonists and/or prostacyclin analogues). Three patients then benefited from shunt closure and the others underwent liver transplantation. Five patients showed improvement or stabilisation of pulmonary arterial hypertension with no deaths after a mean follow-up of 39 months. Based on our limited experience, early and aggressive treatment with a combination of pulmonary arterial hypertension-specific therapy significantly improves patients' haemodynamic profile and enables the performance of liver transplantation and shunt closure with satisfactory outcomes.

Abstract
OBJECTIVE The fetal liver circulation has an important role in fetal growth. The intra-hepatic Umbilical-Porto-Systemic Venous Shunt (IHUPSVS) causes a reduction of the umbilical blood flow to the liver and has been reported to have a restrictive effect on fetal growth. The aim of this study was to evaluate the effect of IHUPSVS on fetal growth. METHODS We conducted a retrospective cohort study of IHUPSVS diagnosed between 2001 and 2019. IHUPSVS was defined as any abnormal communication between any branch of the portal vein and hepatic vein. Pre- and postnatal characteristics were collected from medical files and compared between cases with fetal growth restriction (FGR) and those appropriate for gestational age (AGA). RESULTS Twenty-five fetuses were included in the study. Eighteen (72%) had last estimated fetal weight and birth weight below the 10th centile, four (16%) of them between the third and fifth centile, and 11 (44%) below the third centile. Median gestational age at delivery was lower for FGR than AGA fetuses (37 vs. 38 weeks, p = 0.034) and rate of preterm delivery was higher (38.9 vs. 14.3, P = 0.24). Four cases had associated structural anomalies (2 in each group), and two had minor genetic aberrations (1 in each group). CONCLUSIONS Growth restriction is prevalent in fetuses with IHUPSVS, suggesting that fetal growth should be monitored. In equal measure, in cases with growth restriction, especially without other apparent cause, an intrahepatic shunt should be looked for.

Abstract
BACKGROUND Congenital portosystemic shunts are rare vascular malformations that may have an impact on the heart-lung system. Associated congenital and/or acquired heart diseases are poorly reported. AIMS To analyse cardiovascular disorders within a large congenital portosystemic shunt population, and develop a diagnostic strategy. METHODS Among the 168 consecutive fetuses and children referred for congenital portosystemic shunt (1996-2019), patients presenting with at least one cardiovascular disorder, including congenital heart disease, heart failure, portopulmonary hypertension and/or hepatopulmonary syndrome, were reviewed retrospectively. Cardiovascular disorders were detected using echocardiography and one or more of the following: right-sided heart catheterization; contrast-enhanced transthoracic echocardiography; or lung perfusion radionuclide scan. RESULTS Overall, 46/168 patients with a congenital portosystemic shunt (27.4%) had one or more clinically significant cardiovascular disorders. Congenital heart disease was present in 28 patients, including six with left heterotaxy. Heart failure was present in six fetuses and 21 neonates (eight without congenital heart disease, and 13 with congenital heart disease). In neonates without congenital heart disease, heart function recovered by the age of 3years. Portopulmonary hypertension was identified in 11 patients (mean age at diagnosis: 9years); it was fatal in one patient, and remained stable in five of six patients after congenital portosystemic shunt closure. In six patients, hepatopulmonary syndrome presented as hypoxia (mean age at diagnosis: 5.3years), which reversed after congenital portosystemic shunt closure. CONCLUSIONS Evaluation and monitoring of the cardiopulmonary status of patients with a congenital portosystemic shunt is mandatory to detect and prevent cardiovascular complications. Furthermore, congenital portosystemic shunts must be sought in patients with unexplained cardiovascular disorders, especially when malformations are present.

Abstract
Congenital vascular anomalies affecting the liver have been described in the scientific literature for decades. Understanding these malformations begins with knowledge of hepatic vascular embryology. Surgeons have applied numerous classification systems to describe both intrahepatic and extrahepatic shunts, which can confuse the reader and clinician. In our experience, focusing on one classification system for extrahepatic shunts and one for intrahepatic shunts is better. Today many patients with these shunts carry good long-term prognosis thanks to advances in imaging to better detect shunts earlier and classify them. Timely intervention by skilled radiologists and surgeons have also limited complications arising from dynamic shunts and can avoid a liver transplant. Congenital hepatic shunts are not the only vascular condition affecting the liver. Hereditary hemorrhagic telangiectasia, also known as Osler Weber Rendu syndrome, particularly type 2, may have varying severity of hepatic involvement which warrants longitudinal care from an experienced hepatologist. Lastly, congenital hemangiomas, often first identified on the skin and oral mucosa, also can affect the liver. While most will resolve in infancy and childhood, the pediatric hepatologist must understand how and when to treat persistent lesions and their complications. This article serves as a concise reference to help clinicians better care for patients with these rare conditions.

Abstract
We report a patient without known preexisting liver disease who presented with hepatopulmonary syndrome (HPS) due to aberrant intrahepatic portal venous development leading to portosystemic shunting. Liver transplantation resulted in resolution of portal hypertension and HPS and sildenafil was safely tolerated in the treatment of persistent fatigue and hypoxemia. Twelve months later, patient has normal allograft function and has returned to normal activity.

Abstract
A 33-year-old man presented with hepatic encephalopathy and was diagnosed to have a noncirrhotic extrahepatic portosystemic shunt (NCPSS). He presented with abdominal pain 16 months after the NCPSS diagnosis. Computed tomography revealed thrombosis between the intrahepatic portal vein and the left internal iliac vein, including the NCPSS, and varices of the sigmoid colon. Thrombosis was treated with danaparoid sodium and antithrombin III followed by edoxaban. After treatment, the thrombosis disappeared from the intrahepatic portal vein, but it remained in the NCPSS. The sigmoid colon varices were followed up without any treatment. Follow-up is needed in NCPSS patients in order to make an early detection of complications.
