Is it always negligent to miss a significant fetal
anomaly on a routine ultrasound scan at 20 weeks?
Dr KK Aggarwal & Advocate Ira Gupta
Consumer Commission Order
Judges: Retired Justice Sunil Hali and retired District and Sessions Judge DK
Kapoor
Complainants: Seema Kumari and her husband Atish Kumar
Allegations
Dr KC Sharma and his wife Dr Uma Sharma were
running an ultrasound scanning centre and nursing home at Udhampur “without
adequate qualification, expertise and recognition from Medical Council of
India”.
Missed
Hydrocephalous; it could have been detected
earlier, if the sonographers/sonologists were experienced and suitably
qualified.
Expert’s opinion
Dr Manisha Langer, a qualified radiologist, told
the commission that myelomeningocele can be detected by ultrasound within 15 to
16 weeks of pregnancy. The detection rate improves after 24 to 25 weeks.
Result of missed diagnosis
The pregnancy could not be terminated
Compensation awarded
Rs 20 lakh compensation to the couple for medical
treatment; out of this, Rs 15 lakh to be kept in a fixed deposit for the
child. Rs 15 lakh was awarded as compensation on account of pain and suffering
undergone by the parents, and Rs 1 lakh as litigation charges.
Discussion
Sonographic diagnosis of open spina bifida
typically occurs during the second trimester of the pregnancy.
Modern ultrasound equipment is undoubtedly capable
of producing images that allow diagnosis of anomalies such as open lumbosacral
spina bifida or atrioventricular septal defect. However, such diagnoses can
only be made if considerable operator skill is combined with knowledge and
experience.
In most cases the diagnosis of clinically
significant fetal anomalies is quite straightforward, but evidence suggests
that false-negative results occur regularly.
For example, European Surveillance of
Congenital Anomalies (EUROCAT) (Ultrasound
Obstet Gynecol. 2005;25:6-11) quotes a prenatal detection rate for
spina bifida of only 68%, whilst a recent systematic review (Health Technol Assess. 2000;4:1-193)
reports a detection rate for AV septal defect of just 42%. So, 32% doctors can
miss the diagnosis at 20 weeks.
Was missing the diagnosis negligence?
Is it always negligent to miss a small open
lumbosacral spina bifida (below L3) at a routine 20-week scan without
extenuating circumstances (obesity, oligohydramnios)?
· About 62% of
experts state that it is not negligent to miss such a lesion.
· 24% say it is
not negligent to miss a small spina bifida provided there is documented
evidence of normal intracranial anatomy (absence of head signs).
· Only 4/29
experts will say that such an anomaly should always be detected.
Was termination the choice if the diagnosis would have been done before 20
weeks?
No. Spina bifida is a manageable condition. It is
not an indication of termination by itself. Higher lesion level, larger
segment span and an inter-pediculate distance greater than 10 mm are associated
with poor recovery.
What was the cause?
Probably folic acid not taken by the mother before
the conception
Legal points
· Doctors should
take informed consent from the patient that ultrasound can miss the
diagnosis.
· Was she and if
not, why was she not given folic acid?
· If she was not
on folic acid, then why was the ultrasonologist not alerted to specifically
look for spina bifida?
· One expert
cannot be relied upon, if other experts or opinion say it otherwise.
Answer: This judgment should be challenged
