[Clinical and laboratory study of 7 cases of lupus anticoagulant]

The clinical and laboratory data from seven patients with "Lupus anticoagulant" are reported. Laboratory tests are reliable as far as identification and properties of this kind of anticoagulant are concerned. Clinically, it is dramatic how often these patients show thrombotic phenomena. Clinical or laboratory tests which could point out whether these patients are at risk of incurring into thrombotic or hemorrhagic phenomena are not available, which underlines the critical situation one has to confirm with in case a patient with "Lupus anticoagulant" has to undergo surgery.
