|C||Serial HCG estimation|
1. An ectopic pregnancy is a complication of pregnancy in which the fertilized ovum is developed in any tissue other than the uterine wall.
2. The differential diagnosis is the most common misdiagnosis assigned to early ectopic pregnancy is PID.
3. Signs are:
a. Pain in the lower abdomen, and inflammation
b. Pain while urinating
c. Vaginal bleeding, usually milD. An ectopic pregnancy is usually a failing pregnancy and falling levels of progesterone from the corpus luteum on the ovary cause withdrawal bleeding.
d. This can be indistinguishable from an early miscarriage or the 'implantation bleed' of a normal early pregnancy.
a. Transvaginal examination provides a detailed evaluation of the endometrial cavity and ovaries
b. But compared with compared with Transabdominal USG examinations , TVS suffers from limited sound penetration (far-field imaging) hence the upwardly displaced adnexae may be difficult to characterize at times.
c. MRI examination is time consuming and costly.
d. Its more often used as a “trouble shooter” in difficult diagnosis n stable cases and in acute emergencies, the best investigation to get a quick assessment is indeed the TVS.
e. Computed tomography (CT) scan findings are nonspecific in ectopic pregnancies and pose a hazard of ionizing radiation, which may be harmful to normal pregnancies
