[Risk factors for maternal thromboembolism: clinical predisposition]

Predisposing clinical features in pregnant women are poorly evaluated in the literature. Several factors are undeniable, for example extrinsic compression of the iliac vein (Cockett syndrome), post phlebitis disease, varicose vein disease, and, for most patients, unquantifiable risk factors. Careful assessment of the overall sensitivity to venous thrombosis, on the basis of history taking (patient and family), will allow better assessment of the predisposition to thromboembolism.
