The role of hysteroscopic biopsy in obtaining specimens for cytogenetic evaluation in missed abortion prior to suction dilatation and curettage.

Aim: To estimate whether hysteroscopic-guided biopsy of gestational sac(s) in first trimester missed abortion increases the sensitivity of detecting aneuploidy compared to washing and careful specimen collection after suction dilatation and curettage (D&C).

Materials And Methods: Thirty-five patients with first trimester missed abortion of which 25 underwent 29 suction D&Cs and 10 underwent hysteroscopic-guided biopsy of 12 gestational sacs prior to suction D&C. The karyotype of products of conception specimens were analyzed by G-banding techniques.
