An ectopic or extrauterine pregnancy occurs when a blastocyst implants outside the uterine cavity, most commonly in the fallopian tubes. Ectopic pregnancies remain an important cause of morbidity and mortality as they can be life-threatening. Risk factors include inflammation/infection, prior sterilization, infertility history, smoking, and advanced age. Symptoms may include vaginal bleeding and abdominal pain, though some women experience no symptoms. Diagnosis involves pregnancy tests, ultrasounds, culdocentesis, and laparoscopy. Treatment options include medical management with methotrexate or surgical intervention like salpingostomy or salpingectomy.
