  Placenta Percreta: When Persistent Vaginal Bleeding Is More Than a Routine Post-Abortion Complication Introduction Every year, thousands of women worldwide experience persistent vaginal bleeding after miscarriage, abortion, or delivery. In most cases, clinicians initially suspect retained products of conception (RPOC), uterine atony, or infection. While these diagnoses are common and often appropriate, a small but critically important subset of patients harbors a far more dangerous condition— Placenta Accreta Spectrum (PAS) . Among the PAS disorders, Placenta Percreta represents the most aggressive phenotype. Unlike superficial placental attachment abnormalities, placenta percreta penetrates through the entire myometrium and may invade adjacent organs, particularly the urinary bladder. Failure to recognize this condition early can lead to catastrophic hemorrhage, disseminated intravascular coagulation, multiorgan failure, emergency hysterectomy, or even maternal death. The impor...

 How prenatal Doppler identifies the systemic feeding artery and how postnatal CTA defines the vascular anatomy of fetal extralobar pulmonary sequestration. MediAI by ScholarGen Where Medical Imaging & AI Meets Humanity Executive Clinical Summary A fetal thoracic mass discovered during routine prenatal ultrasonography can immediately raise concern for congenital pulmonary airway malformation, diaphragmatic hernia, bronchogenic cyst, or other developmental abnormalities. Yet one imaging feature can fundamentally change the diagnostic pathway: a systemic feeding artery arising from the aorta . This vascular finding is particularly important in extralobar pulmonary sequestration (ELS) , a congenital malformation consisting of nonfunctioning pulmonary tissue that has no normal bronchial communication and is separated from the normally developing lung by its own pleural covering. The present case illustrates the classic diagnostic sequence. At 21 weeks of gestation , fetal ultrasoun...
