Idiopathic thrombocythemia and pregnancy: report of a case.

Pregnancy and delivery in patients with idiopathic thrombocythemia have not been reported elsewhere, to the knowledge of the authors. Such a case is presented herein. The platelet count decreased with progression of pregnancy, falling to a normal level near term. It was, however, again increased in the puerperium, reaching a level of 1570 X 10(3) per mm3 eight months after delivery. Aspirin was continuously administered throughout pregnancy to prevent thrombus formation, but no adverse effects on the delivery or the infant were observed.
