The occasional occurrence of thrombosis in patients with congenital bleeding disorders has received considerable attention during the past decade. Myocardial infarction, ischemic strokes and venous thromboembolism have been reported in hemophilia A or B patients, in von Willebrand disease and, also, in rare coagulation disorders, especially in factor VII (FVII) deficiency. To explain the relatively high frequency of thrombotic phenomena, mainly venous, seen in the last condition, it was speculated that a special form or variant of FVII deficiency could exist. The presence of associated prothrombotic risk factors has been occasionally reported to be present in these patients but the matter has never been duly evaluated and emphasized. The purpose of the present paper was to evaluate if the clinical setting in which thrombosis appeared in these patients could explain the occurrence of the thrombosis. All reported cases of thrombosis seen in patients with FVII deficiency have been analyzed and the presence of associated risk factors recorded. Out of a population of 33 documented cases, the presence of prothrombotic risk factors was reported in 30 instances. In two of the remaining cases, no mention is made about associated risk factors. In the last case they were explicitly excluded. The critical evaluation of the literature suggests that the occurrence of thrombosis in FVII deficiency may be due to common prothrombotic risk factors. As a consequence it may be only stated that FVII deficiency does not protect from thrombosis.
