Uterine and Peripheral Hematologic Profiles in Molar Pregnancy

Abstract

The potential differences in hematologic profiles of blood samples drawn simultaneously from the right utero‐ovarian vein and from the upper extremity were investigated in four patients with uncomplicated molar pregnancy in stable obstetric conditions. The patients had undergone no previous chemotherapy and were scheduled for total abdominal hysterectomies. The dominant abnormalities in uterine venous blood were prolongation of thrombin time; shortening of activated partial thromboplastin time; positive protamine sulfate test; and increase in coagulation factors II and VII, with a tendency to low values in factor V. Peripheral samples gave almost parallel results in all altered and normal tests, except in one case with very striking differences in factors II, V, VII and X. Several local and systemic influences are discussed. It is concluded that molar pregnancy seems to have important systemic mechanisms affecting the stability of the blood coagulation homeostasis, which act in addition to those at a local level.
