1-12. ECTOPIC PREGNANCY
a. Ectopic pregnancy (figures 1-3 and 1-4) is any pregnancy that does not
occupy the uterine cavity properly. The causes of ectopic pregnancy are abnormally
narrowed fallopian tubes, infection (scar tissue on the fallopian tubes), or tumor
formation. Hemorrhage is extremely serious. The classic symptom is a severe
knife-like pain in the lower abdominant quadrant.
