High-risk third trimester pregnancy with decompensated cirrhosis safely delivered following emergent preoperative interventional radiology for mitigation of variceal bleeding

Pregnancy and the liver

Some of the physiological changes that occur in pregnancy manifest in the liver. These alterations might exacerbate or improve some pre-existent liver diseases, while many conditions remain unaffected. Some hepatic manifestations during pregnancy are secondary to disorders unique to pregnancy. Due to improved management of chronic conditions and assisted conception methods, pregnancies in people with cirrhosis or after liver transplantation are increasingly common. With pregnancy also becoming more common in older people and with the rising prevalence of comorbidities, such as obesity, diabetes, and metabolic syndrome, hypertensive disorders of pregnancy and gestational diabetes are increasing in prevalance. Thus, a broad range of specialists might encounter liver abnormalities in pregnancy, necessitating an understanding of how the liver changes during pregnancy and the importance of multi-disciplinary input to mitigate maternal-fetal risks. From a global health perspective, pregnancy also offers a unique opportunity to influence disease management and initiate interventions that might influence the life course of pregnant people and their families. In this Review, we describe the challenges of diagnosing, risk stratifying, and managing liver disease in pregnancy, and explore factors that might affect future maternal health.

Management of ectopic variceal bleeding with transjugular intrahepatic portosystemic shunt: a systematic review of case reports

Ectopic varices account for 5% of variceal bleedings and occur outside the gastro-esophageal region. This review evaluates the efficacy of transjugular intrahepatic portosystemic shunt (TIPS) for ectopic variceal management. A comprehensive search through PubMed, Scopus, Web of Science, and Embase was conducted until January 16, 2023, using relevant keywords. Case reports and case series with fewer than 10 patients on TIPS for ectopic variceal management were included. The quality assessment followed the Joanna Briggs Institute checklist for case reports. This systematic review evaluated 43 studies involving 50 patients with ectopic varices undergoing TIPS. Patients had a mean age of 54.3 years, half were female, and two were pregnant. Alcoholic liver disease (48%) and hepatitis C infection (26%) were common causes of portal hypertension. Ascites and splenomegaly were reported in 32% and 28% of the patients, respectively. Rectal, oral, and stomal variceal bleeding accounted for 62%, 16%, and 22% of the patients, respectively. Ectopic varices were mainly located in the duodenum (28%) and rectum (26%) regions. Complications affected 42% of the patients, re-bleeding in eleven and hepatic encephalopathy in seven. The follow-up lasted 12 months on average, and finally, 5 received a liver transplant. Mortality post-TIPS was 18%. Despite complications and a notable mortality rate, favorable outcomes were observed in almost half of the patients with ectopic variceal bleeding managed with TIPS. Further research is warranted to refine strategies and improve patient outcomes.

Outcomes of pregnancies complicated by cirrhosis: a retrospective cohort study

BACKGROUND

Although pregnancy complicated by liver cirrhosis is rare, women with cirrhosis experience increased adverse pregnancy outcomes. This study aimed to evaluate pregnancy outcomes in women with liver cirrhosis and develop a predictive model using maternal factors for preterm birth in such pregnancies.

METHODS

A retrospective analysis was conducted on pregnancy outcomes of a cirrhosis group (n = 43) and a non-cirrhosis group (n = 172) in a university hospital between 2010 and 2022. Logistic regression evaluated pregnancy outcomes, and a forward stepwise logistic regression model was designed to predict preterm birth in pregnant women with cirrhosis. The model's predictive performance was evaluated using the receiver operating characteristic (ROC) curve and the area under the ROC curve (AUC).

RESULTS

The incidence of cirrhosis during pregnancy was 0.06% (50/81,554). Pregnant women with cirrhosis faced increased risks of cesarean section, preterm birth, intrahepatic cholestasis of pregnancy, thrombocytopenia, and postpartum hemorrhage. In pregnant women with cirrhosis, preterm birth risk significantly increased at an incidence rate of 46.51% (20/43). According to the prediction model, the key predictors of preterm birth in pregnant women with cirrhosis were intrahepatic cholestasis of pregnancy and total bilirubin. The model demonstrated accurate prediction, with an AUC of 0.847, yielding a model accuracy of 81.4%.

CONCLUSIONS

Pregnant women with cirrhosis face a heightened risk of adverse obstetric outcomes, particularly an increased incidence of preterm birth. The preliminary evidence shows that the regression model established in our study can use the identified key predictors to predict preterm birth in pregnant women with cirrhosis, with high accuracy.
