Ectopic pregnancies, implantation of a fertilized ovum in any location other than within the endometrial cavity, occur in 1-2% of all pregnancies. Despite current enhanced early diagnosis enabled by serum beta-human choriogonadotropin (hCG) levels and high-resolution ultrasound, this clinical entity continues to account for between 2.7 and 6% of all maternal deaths.
