A new case of successful outcome of pregnancy in a carrier of homozygous type II (L99F) antithrombin deficiency.

Abstract Inherited antithrombin deficiency is associated with an increased risk of venous thromboembolism. There is no consensus about pregnancy management in antithrombin deficiency patients because there are very few cases published in the literature. We report a successful pregnancy in a 32-year-old female carrier of a homozygous type II (L99F) antithrombin deficiency who developed a spontaneous deep vein thrombosis at the age of 27 years.
