胚胎停育 中国就医指南

Missed abortion, also known as silent or delayed miscarriage, is a type of early pregnancy loss in which the embryo or fetus has died but remains retained within the uterine cavity without spontaneous expulsion. Unlike inevitable or incomplete abortions, missed abortion typically presents with absent or diminishing pregnancy symptoms—such as nausea, breast tenderness, and fatigue—without vaginal bleeding or cramping, making clinical detection challenging without ultrasound confirmation. Diagnosis requires transvaginal ultrasound demonstrating absence of fetal cardiac activity in a gestational sac measuring ≥25 mm (or ≥16 mm without yolk sac) or an embryo ≥7 mm without detectable heartbeat. Pathogenesis involves chromosomal abnormalities in over 50–70% of cases, most commonly autosomal trisomies (e.g., trisomy 16, 22), monosomy X, or triploidy. Other contributing mechanisms include maternal endocrine disorders (e.g., uncontrolled hypothyroidism, luteal phase defect), thrombophilias (e.g., antiphospholipid syndrome), immunologic dysregulation, chronic endometritis, and structural uterine anomalies (e.g., septate uterus). Environmental and lifestyle factors—including advanced maternal age (>35 years), smoking, excessive caffeine intake, obesity (BMI ≥30), prior recurrent pregnancy loss, and certain infections (e.g., parvovirus B19, listeriosis)—also elevate risk. Epidemiologically, missed abortion accounts for approximately 15–20% of all clinically recognized pregnancies and represents the most common subtype among first-trimester losses. Its incidence rises significantly with maternal age: ~10% in women aged 20–29, ~20% at age 35–39, and up to 40–50% beyond age 40. Psychologically, missed abortion profoundly impacts quality of life—triggering acute grief, anxiety, depression, and feelings of guilt or failure; many patients report prolonged emotional distress, disrupted partner relationships, and diminished sexual well-being. Delayed diagnosis may further exacerbate psychological burden due to uncertainty and perceived loss of control. Physical recovery is generally rapid post-treatment, but recurrent missed abortion warrants comprehensive reproductive immunology and genetic evaluation. Timely, empathetic counseling and multidisciplinary support—including reproductive endocrinology, psychology, and nursing—are essential components of holistic care in reproductive medicine departments.
