classic cesarean section [L, classicus, first-class, Caesar lex, Caesar’s law, sectio, a cutting] , a method for surgically delivering a baby through a vertical midline incision of the upper segment of the uterus. For many practitioners this is the fastest method of cesarean delivery. However, it produces a weaker scar, and, because the upper segment is thicker and more vascular, more bleeding occurs during surgery than from the low cervical cesarean section. Compare extraperitoneal cesarean section. See also cesarean section.
