Risks and complications of IVF treatment?

How is ectopic pregnancy diagnosed?

Unfortunately, to date, there is no available method of diagnosing ectopic pregnancy with 100% accuracy. A high index of suspicion in patients at risk is the cornerstone of early diagnosis. Recent advances in the measurement of blood beta hCG (the pregnancy hormone), progesterone and the development of high-resolution ultrasound scanning has greatly improved the early diagnosis of ectopic pregnancy and has made it possible to offer conservative treatment. A negative beta hCG result virtually excludes any risk of significant ectopic pregnancy. Several measurements of beta hCG over 48 hours may be performed to see if it is rising or falling.

Ectopic pregnancies not only tend to produce lower levels of these hormones than normal pregnancies, but the levels of these hormones also do not rise as rapidly. It is not always possible to see an ectopic pregnancy with an ultrasound scan, but the diagnosis of ectopic pregnancy is always suspected if the ultrasound scan showed an empty uterus but the pregnancy test is positive. Heterotopic pregnancies usually produce hormone levels similar to those of normal intrauterine pregnancies, and in these cases, a vaginal ultrasound scan (which gives a better image of the uterus, tubes and ovaries than abdominal scan), is the main tool for making the diagnosis.

Until recently, laparoscopy was the gold standard method for diagnosis of ectopic pregnancy and is still the method of choice where there is no facilities for performing the blood tests and ultrasound scanning, a laparoscopy will be advised to inspect the Fallopian tube and ovaries. In a severe emergency, for example if a patient collapse, a laparotomy will be needed and a blood transfusion may be required to replace blood loss.

What are the chances of making a definitive diagnosis of ectopic pregnancy without clinical suspicion and normal adnexae only on ultrasound examination? a sonologist may not have all the clinical parameters for making a positive diagnosis. What are the legal implications if you miss an early ectopic and patient presents with clinical symptoms one week after the intial sonogram? Again, it may be that at the time of sonogram patient may have had a pregnancy less than 5 weeks.
