Indications for examination of spontaneous abortion specimens: a reassessment

The clinical evaluation of recurrent pregnancy loss is assessed in light of recent technical advances in trophoblast culture, ultrasonography, and chromosome analysis. With an algorithm based on karyotype results, cost-benefit calculations confirm that an average savings of $1099.47 per patient could be achieved if a policy of karyotype analysis of recurrent abortion specimens was emphasized. It is estimated that a specific chromosomal cause could be identified in 45% to 70% of such cases. A more concerted effort should be made to culture trophoblast tissue from recurrent pregnancy losses; such a policy would result in both emotional and financial rewards.
