Abortion Spontaneous abortion Artificial abortion
Abortion • Defined as delivery occurring before the 28th completed week of gestation • Fetus weighing less than 1000g • US ( before the 20th completed week of gestation) • Early abortion and late abortion • 15% of clinically evident pregnancies • 80% of abortions prior to 13 weeks’ gestation
Etiology • Abnormal karyotype: 50%-33.3%-5%(early-mid-late) • Maternal factors: infection (TORCH) endocrine factors immunologic factors maternal systemic disease anatomic defects trauma • Toxic factors • Father factors
Pathology • Hemorrhage into the decidua basalis • Necrosis and inflammation • Uterine contractions and cervical dilatation • Expulsion of most or all of the products of conception <8w 8~12w >12w
Clinical Findings Amenorrhea Bleeding Pain
Clinical Findings Threatened Abortion Without cervical dilatation Without extrusion of products of conception Inevitable Abortion Cervical dilatation Without extrusion of products of conception
Clinical Findings Bleeding severe Incomplete Abortion Expulsion of some, but not all of the products of conception Complete Abortion Expulsion of all of the products of conception
Clinical Findings Missed Abortion Embryo or fetus death, products of conception in utero Pain Septic Abortion Infection of the uterus
Clinical Findings Recurrent Spontaneous Abortion ≥three times abortion
Laboratory Findings Gestational sac and viable embryo with heart motion Ultrasonography Pregnancy tests HCG Blood count Anemic
Complication Life threatening Severe hemorrhage Infection Intrauterine synechia Perforation
Diagnosis Medical history Physical examination ? Accessory examination
Threatened Abortion Inevitable Incomplete Missed
Treatment Threatened Abortion Bed rest Forbid sexual life Progesterone
Treatment pathological examination Dilatation and curettage InevitableAbortion Oxytocin Ultrasound Antibiotics
Treatment Dilatation and curettage Promptly IncompleteAbortion Blood type and cross-match Fluid infusion Antibiotics
Treatment Products of conception Examine Complete Abortion Ultrasound Bleeding
Treatment DIC Estrogen Missed Abortion Dilatation and curettage(<12w) Second RU486 and PG(>12w) Oxytocin
Treatment Genetic error Anatomic defect Hormonal abnormalities Infection Systemic disease Immunologic factors Cause Recurrent spontaneous Abortion Habitual Abortion Cervical cerclage Progesterone
Treatment Antibiotics Septic Abortion Dilatation and curettage Cervical cultures
Definition A fertilized ovum implants in an area other than the endometrial lining of the uterus.
Sites of ectopic pregnancy >95% ectopic pregs in fallopian tubes 78% ampulla 12% isthmic 11.1% fimbrial 3.2% ovarian 2.4% interstitial 1.3% abdominal
Etiology • Tubal factors (salpingitis, previous tubal surgery) • Tubal dysplasia • ART • Exogenous hormone (oral contraceptives) • Other factors (endometriosis, IUD)
Pathology • Lackage of resistance to invasion by the trophoblast • Abdominal pregnancy -1:15000 pregnancies • Enlarged uterus and endometrium changes(A-S)
Termination of the pregnancy Abortion incomplete complete Rupture
Temination of the pregnancy • Tubal:abortion or missed abortion • Interstitial,Angular,Cornual:rupture into the uterine cavity,the broad ligament or the peritoneal cavity. • Cervical:rupture into the cervical canal • Abdominal:rupture into the peritoneal cavity,into the retroperitoneal space • Ovarian:rupture into the peritoneal cavity
Clinical Findings • Symptoms of early pregnancy (amenorrhea, breast tenderness, and nausea) • Bleeding (usually spotting) • Diffuse lower abdominal pain • Over 15% of ectopic pregnant as surgical emergencies.
Symptoms Pain • Pelvic or lower abdominal pain (99%) • Generalized pain (44%) • Unilateral lower abdominal pain (33%) • Subdiaphragmatic pain or sharp shoulder pain (22%) Secondary amenorrhea (68%) Abnormal uterine bleeding (75%) Syncope (37%)
Signs • Abdominal tenderness (80%) • Adnexal tenderness (75%) • Adnexal mass(a unilateral adnexal mass:53%) • Uterine changes (normal size:71%,6-8 weeks’ size:26%, 9-12 weeks’ size:3%) • Fever (only about 2% of patients)
Laboratory Findings • Pregnancy tests (postive-82.5%) • Hematocrit • White blood cell count • A negative test does not rule out an ectopic gestation
Special Examinations • Utrasonically scanning • Culdocentesis • Dilatation and curettage • Exploratory laparotomy
Differential Diagnosis • Appendicitis • Salpingitis • Ruptured corpus luteum cyst • Uterine abortion • Twisted ovarian cyst • Urinary tract disease • Degenerating leiomyomas
Diagnosis • Amenorrhea followed by irregular vaginal bleeding • Adnexal tenderness or mass • Ultrasonographic evidence of adnexal mass and no intrauterine gestation • Positive ß-hCG
Complications • About I in 1000 ectopic pregnancies result in maternal death • Untreated or mistreated ruptured ectopic tubal pregnancy 8-12% of all materal deaths • The majority of these deaths are preventable Death
Complications Tubal damage • Chronic salpingitis • Infertility or sterility • Intestinal obstruction may develop after hemoperitoneum and peritonitis
Treatment • Emergency Treatment Immediate surgery,anti-shock(warm,oxygen) salpingectomy • Surgical treatment persistent ectopic pregnancy • Medical treatmemt-MTX • Supportive treatment antibiotic, iron therapy a high-proteindiet
Indications for Conservative Drug Therapy • No signs of active intra-abdominal bleeding • Diameter of mass ≤3cm • Serum ß-hCG <2000U/L • No embryonic blood vessle pounding • No contraindication for MTX application • Normal liver and kidney function • Normal RBC count
Prognosis • Another tubal pregnancy will occur in 10-20% of patients treated • Infertility develops in approximately 50% of patients
