[Changes in antithrombin III concentration in gestosis patients].

Antithrombin-(AT)-III-levels from 22 patients were determined at the day of delivery but also at the first and fifth day post partum. 7 patients had an AT-III-level in a pathologically low range. Furthermore we found a close correlation between the degree of seriousness of gestosis and AT-III-reduction as well as hypercoagulolability expressed in an elevated normotest. With two patients serious complications arised intra- and postoperatively. One patient got a coagulopathy during the sectio, the other patient developed in spite of heparin treatment a deep thrombosis in the leg vein. These women had the lowest AT-III-levels from all 22 patients. These results underline the importance of an AT-III-control, above all with surgical operations of gestose patients.
