Abstract
RATIONALE: Subchorionic Hematoma, often referred to as Bruce hematoma, can lead to serious obstetric complications such as intrauterine growth restriction and fetal death, as well as early and late pregnancy miscarriage, placental abruption, and premature rupture of membranes, posing great harm to both mother and fetus. PATIENT CONCERNS: At present, Western medical treatments have not shown satisfactory results, necessitating the discovery of more effective clinical treatment methods. DIAGNOSES: Threatened miscarriage, Subchorionic hematoma, Iron deficiency anemia (mild). INTERVENTIONS: Sanji Peiyuan decoction combined with dydrogesterone. OUTCOMES: Following 17 days of treatment with Sanji Peiyuan decoction and oral dydrogesterone tablets, the hematoma was no longer detectable by ultrasound. The patient experienced no symptoms such as abdominal pain, bloating, or vaginal bleeding. She successfully gave birth around her due date, with both the mother and child in good health. LESSONS: The combination of Sanji Peiyuan decoction and oral dydrogesterone tablets shows promising clinical efficacy in treating Massive Subchorionic Hematomas. This method merits further clinical research.
