Abstract: Placental abruption has classically been defined as the premature separation of a normally located placenta before delivery of the fetus. Traditionally, this diagnosis was based on clinical symptoms, including vaginal bleeding, pain, and fetal distress. This definition, however, preceded the advent of obstetric ultrasound. Ultrasound frequently identifies various hemorrhagic lesions, such as retroplacental, subchorionic, intraamniotic, intraplacental, and preplacental hematomas in both symptomatic and asymptomatic patients. These variable ultrasound findings lead to new challenges as to what to define as an abruption, particularly in the absence of symptoms. This ambiguity in defining placental abruption affects clinical decision-making and hinders our understanding of the pathophysiology of abruption, presenting challenges in studying abruption. It is likely that these varying sonographic findings may precede the classic presentation of vaginal bleeding and pain and therefore are often concealed abruptions. This commentary highlights the importance of developing clear diagnostic guidelines for placental abruption, given its association with severe outcomes including a high rate of perinatal mortality and maternal morbidity. We aim to elucidate the complexities of ultrasound diagnosis in placental abruption, advocating for precise criteria to better guide clinical practice. We propose that these ultrasound findings of hemorrhagic placental lesions after 20 weeks of gestation in asymptomatic patients should be considered part of the spectrum of abruption, while in symptomatic patients should be taken as confirmation of the diagnosis of abruption.
