Umbilical-portal-systemic venous shunt and intrauterine growth restriction: an inquiry from a prospective study. Am J Obstet Gynecol 2024; 231:340.e1-340.e16. [PMID: 38218510 DOI: 10.1016/j.ajog.2024.01.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 12/22/2023] [Accepted: 01/01/2024] [Indexed: 01/15/2024]
Abstract
BACKGROUND The investigation of the fetal umbilical-portal venous system is based on the premise that congenital anomalies of this system may be related to adverse perinatal outcomes. Several small retrospective studies have reported an association between umbilical-portal-systemic venous shunts and intrauterine growth restriction. However, the prevalence of portosystemic shunts in the fetal growth restricted population is yet to be determined. OBJECTIVE The aims of this study were (1) to determine the prevalence of fetal umbilical-portal-systemic venous shunts in pregnancies complicated by intrauterine growth restriction and (2) to compare the perinatal and neonatal outcomes of pregnancies with intrauterine growth restriction with and without umbilical-portal-systemic venous shunts. STUDY DESIGN This was a prospective, cross-sectional study of pregnancies diagnosed with intrauterine growth restriction, as defined by the Society for Maternal-Fetal Medicine intrauterine growth restriction guidelines. All participants underwent a detailed anomaly scan, supplemented with a targeted scan of the fetal portal system. Venous shunts were diagnosed using color Doppler mode. The perinatal outcomes of pregnancies with intrauterine growth restriction with and without umbilical-portal-systemic venous shunts were compared. RESULTS A total of 150 cases with intrauterine growth restriction were recruited. The prevalence of umbilical-portal-systemic venous shunts in our cohort was 9.3% (n=14). When compared with the control group (intrauterine growth restriction without umbilical-portal-systemic venous shunts, n=136), the study group had a significantly lower mean gestational age at the time of intrauterine growth restriction diagnosis (29.7±5.6 vs 32.47±4.6 weeks of gestation; P=.036) and an earlier gestational age at delivery (33.50±6.0 vs 36.13±2.8; P=.005). The study group had a higher rate of fetal death (21.4% vs 0.7%; P<.001) and, accordingly, a lower rate of live births (71.4% vs 95.6%; P=.001). Additional associated fetal vascular anomalies were significantly more prevalent in the study group than in the control group (35.7% vs 4.4%; P≤.001). The rate of other associated anomalies was similar. The study group had a significantly lower rate of abnormal uterine artery Doppler indices (0% vs 40.4%; P=.011) and a higher rate of abnormal ductus venosus Doppler indices (64.3% vs 23%; P=.001). There were no cases of hypertensive disorders of pregnancy in the study group, whereas the control group had an incidence of 12.5% (P=.16). Other perinatal and neonatal outcomes were comparable. CONCLUSION Umbilical-portal-systemic venous shunt is a relatively common finding among fetuses with growth restriction. When compared with pregnancies with intrauterine growth restriction with a normal portal system, these pregnancies complicated by intrauterine growth restriction and an umbilical-portal-systemic venous shunt are associated with a different Doppler flow pattern, an increased risk for fetal death, earlier presentation of intrauterine growth restriction, a lower gestational age at delivery, additional congenital vascular anomalies, and a lower rate of pregnancy-induced hypertensive disorders. Meticulous sonographic evaluation of the portal system should be considered in the prenatal workup of intrauterine growth restriction, as umbilical-portal-systemic venous shunts may affect perinatal outcomes.

Abstract
Budd-Chiari syndrome is a heterogeneous group of disorders characterized by hepatic venous outflow obstruction that involves one or more draining hepatic veins. Its occurrence in populations in the western hemisphere is commonly associated with hypercoagulative states. Clinical manifestations in many cases are nonspecific, and imaging may be critical for early diagnosis of venous obstruction and accurate assessment of the extent of disease. If Budd-Chiari syndrome is not treated promptly and appropriately, the outcome may be dismal. Comprehensive imaging evaluations, in combination with pathologic analyses and clinical testing, are essential for determining the severity of disease, stratifying risk, selecting the appropriate therapy, and objectively assessing the response. The main goal of treatment is to alleviate hepatic congestion, thereby improving hepatocyte function and allowing resolution of portal hypertension. Various medical, endovascular, and surgical treatment options are available. Percutaneous and endovascular procedures, when performed in properly selected patients, may be more effective than medical treatment methods for preserving liver function and arresting disease progression in the long term. In addition, such procedures are associated with lower morbidity and mortality than are open surgical techniques.

Abstract
OBJECTIVE The purpose of our study was to describe the imaging findings in incidentally discovered intrahepatic portal venous shunts. CONCLUSION Intrahepatic portal venous shunts are uncommon hepatic vascular anomalies that are often not associated with manifestations of liver disease or symptoms. They are most often solitary and in the left hepatic lobe. Identification of 25 intrahepatic portal venous shunts at a single institution over 6 years suggests that they may be more common than previously known and that with an increasing use of imaging, they may be identified more often in the future.

Abstract
PURPOSE To understand systemic the influence of stent therapy for inferior vena cava (IVC) obstruction due to advanced liver tumor. METHODS Seven patients with symptomatic IVC obstruction due to advanced primary (n = 4) or secondary (n = 3) liver tumor were subjected to stent therapy. Enrollment criteria included high IVC pressure over 15 mmHg and the presence of edema and ascites. Z-stents were deployed using coaxial sheath technique via femoral venous puncture. Physiologic and hematobiochemical parameters were analyzed. RESULTS All procedures were successful, and the stents remained patent until patient death. Promptly after stent placement, the IVC flow recovered, and the venous blood pressure in the IVC below the obstruction level showed a significant decrease from 20.8 +/- 1.2 mmHg (mean +/- SE) to 10.7 +/- 0.7 mmHg (p < 0.01). Transient mild increase of right atrial pressure was observed in 1 patient. During the following week prominent diuresis was observed in all patients. Mean urine output volume in the 3 days before the stent therapy was 0.81 +/- 0.09 l/day compared with 2.1 +/- 0.2 l/day (p < 0.01) in the 3 days after. The edema and ascites decreased in all patients. The caval pressure change correlated well (r > 0.6) with the urine volume increase, and with the decreased volume of edema and ascites. The urine volume increase correlated well with the decrement of edema, but not with that of ascites. Improvements for various durations in the levels of blood urea nitrogen, serum creatinine, lactate dehydrogenase, fibrinogen, and platelet count were found (p < 0.05). These hematobiochemical changes were well correlated with each other and with the decrement of ascites. Two patients showed a low blood sodium level of 128.5 mEq/l after intensive natriuresis, and one of them died on day 21 with hepatic failure, which was interpreted as maladaptation aggravation. The mean survival time was 94.1 +/- 34.1 days (mean +/- SD), ranging from 21 to 140 days after stent treatment. CONCLUSION The stent therapy for IVC obstruction due to malignant liver tumors was followed by a series of physiologic and hematobiochemical consequences, most of them favorable but some possibly unfavorable. Rational interpretations and predictions of sequelae based on physiologic science including cardiology, hepatology, and nephrology would facilitate the best management of stent therapy for malignant IVC obstruction.

Abstract
Intrahepatic portal-systemic venous shunt is defined as a communication between the portal and the systemic-venous circulation, measuring more than 1 mm in diameter and at least partially located inside the liver. This is a rare condition, and the etiopathogenesis is unclear. Of the various types, Type I, with patent paraumbilical veins, located in the liver, is commonly encountered in portal hypertension. Other types are much less common. Only 47 cases have been reported in the entire French and English literature. Shunts may be congenital or acquired. This report describes a case of portal-systemic encephalopathy due to a spontaneous large-caliber portal-hepatic venous shunt in the right lobe of the liver confirmed by percutaneous transhepatic portography and hepatic venous angiogram. The treatment with coil embolization was successful, and hepatic encephalopathy resolved postoperatively with normalization of ammonia level. The etiology of the shunt was unclear. Given the age of the patient, the shunt was thought to have developed spontaneously.

Abstract
OBJECTIVE Intrahepatic portosystemic venous shunt is relatively rare and not well recognized. Awareness of intrahepatic communications is important because they can cause encephalopathy, and most of these shunts can be completely cured by transcatheter embolization. In this study, we describe the angiographic findings and transcatheter embolization techniques using several approaches for the treatment of intrahepatic portosystemic venous shunt. MATERIALS AND METHODS Between 1989 and 2001, we treated 10 patients with symptomatic intrahepatic portosystemic venous shunt by performing transcatheter embolization with Gianturco coils, fibered platinum coils, detachable balloons, and detachable microcoils using one of three approaches to access the portal venous system: transileocolic obliteration (n = 2), percutaneous transhepatic obliteration (n = 4), or retrograde transcaval obliteration (n = 4). RESULTS In all patients, complete obliteration or nearly complete obliteration was confirmed angiographically, and symptoms related to portal-systemic encephalopathy improved after treatment. Complications were observed in three patients: adhesive ileus in a patient treated by transileocolic obliteration and thrombosis of intrahepatic portal branches in two patients treated by percutaneous transhepatic obliteration. CONCLUSION On angiography, two types of intrahepatic portosystemic venous shunt were seen: intrahepatic portal venous-hepatic venous communication and intrahepatic portal venous-perihepatic venous communication. Transcatheter embolization is effective for treatment of intrahepatic portosystemic venous shunt. Retrograde transcaval obliteration is the least invasive technique and is recommended as the first choice for treatment of portosystemic venous shunt except in patients with multiple shunts.

Abstract
Congenital portosystemic venous shunt (PSVS), considered to be a rare disease, can lead to hepatic encephalopathy (HE). With improvements in diagnostic imaging techniques, the number of infants and children with documented PSVS has increased. The natural course of the disease and indications for surgical closure of the shunt vessel have not been well defined. We reviewed 51 cases of congenital PSVS in Japan; 34 patients had an intrahepatic PSVS, and 17 had an extrahepatic PSVS. There were 12 patients with HE at the time of diagnosis. The frequency of HE increased in subjects over 60 years of age. Children with HE had a shunt ratio exceeding 60%. When the shunt ratio was less than 30%, HE did not occur. Twenty of 28 patients under the age of 15 years had hypergalactosemia at the time of neonatal screening. Part of the congenital intrahepatic PSVS spontaneously closed. Surgical closure of a PSVS may be an approach expected to prevent HE when the shunt ratio exceeds 60%.

Abstract
A 57-year-old woman presented with hepatic encephalopathy, cirrhosis, and a dual-channel portosystemic venous shunt (PSVS). The shunt was treated successfully by embolization with steel coils via retrograde systemic venous access. Encephalopathy resolved. This new approach is considered safer than the previously reported percutaneous transhepatic route or the mesenteric venous route, requiring a mini-laparotomy.
