Abstract
RATIONALE: Spontaneous subcapsular hepatic hematoma (SSHH) is a rare yet severe complication of hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome that can lead to life-threatening situations for both the mother and fetus. Determining an appropriate therapeutic strategy remains challenging, as it involves choosing between surgery, microinvasive percutaneous transhepatic drainage, or conservative treatment alone. Further successful cases are needed to support the optimal option. We retrospectively collected a patient's clinical record and imaging data to elucidate the natural progression, response to noninvasive treatment, and outcome of SSHH associated with HELLP syndrome. PATIENT CONCERNS: A 34-year-old woman, who underwent a cesarean section due to suspected fetal distress, developed SSHH accompanied by the potential risk of rupture and deteriorated serology within the first 24 hours after delivery. DIAGNOSES: Emergency blood routine examination, serum biochemistry analysis, and computed tomography of the abdomen revealed a SSHH associated with HELLP syndrome. INTERVENTIONS: The main rescue measures included the use of corticosteroids, antihypertensive drugs, and platelet transfusion. OUTCOMES: A positive effect on the patient's condition was exhibited within 24 to 48 hours. The majority of the subcapsular hepatic hematoma could be absorbed without any sequelae over a period of 7 months. LESSONS: For patients with pregnancy-induced hypertension, there is a heightened risk of HELLP syndrome occurrence in subsequent pregnancies. The assessment and treatment of SSHH should be conducted by an experienced multidisciplinary team. In addition to timely delivery, the administration of corticosteroids, usage of antihypertensive medication, and platelet transfusion are necessary, particularly within the first 48 hours if the patient's condition permits. This approach would provide valuable insights for further therapeutic decisions and facilitate a preliminary prognosis assessment.
