There is limited evidence on the management of this rare condition. Here, we present a case of HCSP in which US\u2010guided selective reduction of the CS pregnancy (CSP) was performed using potassium chloride (KCl) to salvage the intrauterine pregnancy. We also conducted a review of published case reports to understand the determinants of outcome.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>After a MEDLINE search, 23 case reports were found eligible based on quality assessment and were included in the analysis. A composite\u2010score indicating overall obstetric morbidity was computed, and mixed\u2010effects linear regression was implemented to identify its predictors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>US\u2010guided local treatment was the most common mode of intervention for HCSP. The regression analyses revealed that the poor obstetric outcomes, especially antepartum haemorrhage (APH) and postpartum haemorrhage (PPH), were significantly predicted by advanced gestational age at treatment and a higher number of previous CS, irrespective of the mode of treatment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>These results indicate that a high index of suspicion for an early ultrasound diagnosis and treatment is critical. US\u2010guided techniques are useful in salvaging the intrauterine pregnancy with decreased maternal morbidity. The results are preliminary due to the rarity and a small number of published reports. Every CSP should be recorded in a central international registry to obtain reliable data on the diagnosis and management of women with CSP. Given the rising rates of CS, future systematic studies are warranted.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ajum.12242","type":"journal-article","created":{"date-parts":[[2021,3,15]],"date-time":"2021-03-15T11:42:21Z","timestamp":1615808541000},"page":"70-77","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Ultrasound\u2010guided
