Summary
Fetal skin dimpling and scarring can occur from amniocentesis, even with ultrasound guidance. This study describes two infants with such injuries, highlighting a rare but possible complication of the procedure.
Area of Science:
- Perinatology
- Fetal Medicine
- Pediatric Dermatology
Background:
- Amniocentesis is a common prenatal diagnostic procedure.
- Real-time ultrasonography is routinely used to guide amniocentesis.
- Historically, cutaneous lesions post-amniocentesis were reported before widespread ultrasound use.
Observation:
- Two infants presented with multiple pitted scars on the thighs and abdomen.
- These scars were attributed to fetal skin dimpling caused by needle puncture during amniocentesis.
- No associated internal injuries were noted in either case.
Findings:
- Diagnostic amniocentesis was performed in the second trimester for both mothers.
- Despite real-time ultrasound monitoring, fetal needle puncture scarring occurred.
- The observed scarring was superficial, affecting only the skin.
Implications:
- Real-time ultrasound does not entirely prevent fetal needle puncture injuries.
- Fetal skin dimpling and scarring represent a rare complication of amniocentesis.
- Clinicians should be aware of this potential risk when performing prenatal procedures.
