Fimbrial ectopic pregnancy

The fimbriae are delicate, finger-like projections at the end of each fallopian tube that help guide an egg into the tube. In a fimbrial ectopic pregnancy, pregnancy tissue is outside the womb near this end rather than implanted in the womb lining. As it grows, it can cause bleeding inside the abdomen and become life-threatening.

Risk factors can include previous ectopic pregnancy, damage to the tubes, pelvic inflammatory disease, fertility treatment, or pregnancy with an intrauterine device in place. Some people have no known risk factor. A positive pregnancy test with pain or bleeding needs assessment because symptoms alone cannot show the pregnancy's location.

Contact an urgent medical service if you have a positive pregnancy test with pelvic pain, shoulder-tip pain, dizziness, or vaginal bleeding. Assessment may include blood tests taken over time and a transvaginal ultrasound; very early pregnancies may not yet be visible, so repeat review can be needed. Treatment may involve close monitoring, medicine in selected cases, or surgery. A salpingectomy removes the affected fallopian tube when surgery is required; the choice depends on bleeding, scan findings, health, and future fertility considerations.

Call emergency services or go to an emergency department for sudden severe abdominal or pelvic pain, fainting, collapse, shoulder-tip pain, heavy bleeding, extreme weakness, or breathing difficulty. These may signal internal bleeding. Do not drive yourself if you feel faint. Even mild symptoms need prompt clinical advice when pregnancy is possible.

Where is the pregnancy located? What do my blood tests and scan show? When should testing be repeated? Am I suitable for monitoring or medicine, or is surgery safer? How might treatment affect future pregnancy plans?
