[Contemporary biopsy for diagnosis of abortion residues: preliminary experience].
The differential diagnosis between abortion and ectopic pregnancy has important clinical implications. In this report we have tested the accuracy of frozen sections in uterine curettings to identify intrauterine pregnancy. Uterine curettings with a diagnosis of products of gestation, from 104 patients were studied. In all of them plasmatic levels of B Gonadotrophin were measured. The curetting material was fixed and studied on frozen sections and on paraffin embedded tissue. A high positive relationship between frozen and embedded material was observed. The sensibility, specificity, positive and negative predictive value of the frozen section to detect chorionic villi were 90.6; 100; 100 and 74% for each of them.
