Deep cerebral venous thrombosis and hereditary tissue plasminogen activator (t-PA) deficiency.

We describe a patient with defective tissue plasminogen activator (t-PA) release who developed internal cerebral vein thrombosis. She recovered completely and, as shown by MRI, favourable outcome was probably related to vascular recanalisation. Other members of the pedigree had a similar fibrinolytic deficiency without clinical manifestations.

Reversible cerebral ischemias: a comparative analysis of risk factors in TIAs and in RINDs.

A retrospective study in which 709 patients, 522 with RIND and 187 with TIA, were compared in respect of common risk factors (RFs) for acute cerebrovascular disease. The two forms of the disease differed significantly in respect of smoking, hematocrit, hypercholesteremia, hypertriglyceridemia and hyperuricacidemia. Although these RFs do not seem to be determinants of or discriminants between the two forms of acute cerebrovascular disease, it is nonetheless highly probable that, together with all the other RFs, they have a facilitatory role.
