Risk factors for fetal loss after Amniocentesis are identified. (Large Retrospective study).
The risk of fetal loss after amniocentesis is elevated in women aged 40 and over and in those with a history of vaginal bleeding in the current pregnancy or repeated fetal loss, a large retrospective study suggests.
