Prenatal sonographic characteristics and postnatal outcomes of congenital portosystemic shunt diagnosed during the fetal period: a systematic review.
Synthesis in Orphanet journal of rare diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCongenital portosystemic shunt (CPSS) is a rare vascular malformation which results in anomalous communication between the portal venous system and the systemic vein. The objective of this review is to describe the prenatal ultrasonic characteristics and postnatal outcomes of CPSS diagnosed prenatally, along with providing some suggestions for perinatal monitoring. MATERIALS AND
methodsA systematic literature search was conducted in PubMed and Ovid electronic databases in a period from January 2012 to May 2024, using the terms: "congenital portosystemic shunt", "ductus venosus", "Abernethy malformation" and "umbilical-portal-systemic venous shunt". All original studies reporting CPSS patients diagnosed prenatally were included. Studies published in languages other than English or studies that did not report the clinical information of patients were excluded. Two reviewers independently screened articles for inclusion and extracted data.
resultsA total of 39 studies which included 525 cases were enrolled in the systematic review. Among the included patients, 49 (9%) had umbilical-systemic shunt (USS), 264 (50%) had ductus venosus-systemic shunt (DVSS), 159 (30%) had intrahepatic portal-systemic shunt (IHPSS), 32 (6%) had extrahepatic portal-systemic shunt (EHPSS) and 9 (2%) had mixed shunts which meant that they had more than one type of shunts. There were also 12(3%) patients were excluded because the specific type was not described in the study. CPSS patients could have severe comorbidities such as chromosomal aberrations and cardiovascular malformations. Compared with other groups, fetuses with IHPSS had the lowest incidence of severe comorbidities. Most patients received conservative treatment while interventional and surgical treatments were used for some patients.
conclusionWe suggest that fetuses diagnosed with CPSS should be treated differently according to their types and clinical manifestations. IHPSS patients are more likely to have good outcomes so they may benefit from the "wait-and-see" approach while the other groups deserve closer monitoring. Personalized treatment is essential as CPSS patients can be asymptomatic or have severe complications.
