[t(y)o̅o̅′bəl]

Etymology: L, tubus + ab, away from, oriri, to be born

a condition of pregnancy in which an embryo, ectopically implanted, is expelled from the uterine tube into the peritoneal cavity. Tubal abortion is often accompanied by significant internal bleeding, causing acute abdominal and pelvic pain, or it may be asymptomatic, the products of conception being resorbed. Rarely the conceptus reimplants on the peritoneum and continues growing to become an abdominal pregnancy. See also abdominal pregnancy, ectopic pregnancy, tubal pregnancy.
