Unprovoked Pulmonary Embolism in Factor VII Deficiency

Acta Haematol. 2020;143(2):181-183. doi: 10.1159/000500441. Epub 2019 Oct 7.

Abstract

Thrombotic events in bleeding disorders such as hemophilia A or B, Von Willebrand disease, afibrinogenemia, factor VII deficiency, and factor XI deficiency are rare but have been reported. These events usually occur in the presence of prothrombotic risk factors such as recent surgery, trauma, or factor replacement therapy. We present a case of a 68-year-old Hispanic female with a history of factor VII deficiency who presented with shortness of breath, chest pain, and palpitations and was found to have pulmonary embolism. Our patient did not have any of the above-mentioned thrombotic risk factors. Our case and review of the literature show that factor VII deficiency does not provide protection against thrombosis.

Keywords: Factor VII deficiency; Pulmonary embolism; Thrombotic risk factors.
