The objective of this study is to gather information that corroborates the main clinical and laboratory findings involving Hellp Syndrome, its repercussions and consequences during pregnancy. An Integrative review was carried out in August 2024, using the digital library Scientific Electronic Library Online (SciELO), the Virtual Health Library (VHL) and PUBMED in the databases using the Boolean operators: AND and OR. The results were obtained through management with the Rayyan 16 QCRI application and were structured in PRISMA flowcharts. With the search in the databases, 219 articles were found, of which 122 were selected for reading and, according to the objective of the present work, 10 articles were included in the research. In the studies observed, it is concluded that among the main hypertensive syndromes in pregnancy, HELLP syndrome is a specific clinical and laboratory entity, requiring early diagnosis, precisely because of the repercussions at the maternal-fetal level, as it increases complications such as the syndrome from respiratory distress, infections and long-term developmental problems.
