Cornual pregnancy on USS?
visualisation of a single interstitial portion of fallopian tube in the main uterine body, gestational sac/products of conception seen mobile and separate from the uterus and completely surrounded by myometrium, and a vascular pedicle adjoining the gestational sac to the unicornuate uterus
When is expectant management of ectopic an option?
US diagnosis of ectopic and decreasing hCG level, initially >1500
When is MTX management appropriate for ectopic management?
Cervical ectopic management?
MTX
Surgical management has high failure rate, so only if bleeding +++
CS scar ectopic management?
MTX into GS + SEVAC
Interstitial pregnancy management?
MTX or surgical management by laparoscopic cornual resection or salpingotomy or hysteroscopic resection with lap/US guidance
Management of heterotopic pregnancy
Local injection of potassium chloride or hyperosmolar glucose with aspiration of the sac contents (e.g. transvaginally)
Surgical removal of the ectopic pregnancy
How to give MTX in ectopic management?
MTX usually single IM dose of 50 mg/m2.
Serum β-hCG levels are measured on days 4 and 7 post methotrexate.
If the β-hCG level decreases by more than 15% between days 4 and 7, β-hCG levels are then measured weekly until less than 15 iu/l.
If the level does not decrease by 15%, a repeat transvaginal ultrasound should be considered to exclude ectopic fetal cardiac activity and the presence of significant haemoperitoneum. Consideration may then be given to administration of a second dose of methotrexate
Success rate single dose MTX?
65-95%
Sensitivity and FPR - 1st trimester screening
90%, 5%
