Neurology India. 1999 Jun; 47(2): 155-6http://imsear.searo.who.int/handle/123456789/12008511 references.A deficiency of plasma antithrombin III has been identified as a potential risk factor for thrombosis. In a pilot study of 56 patients aged less than 40 years who presented with ischaemic stroke of unknown etiology, we detected only one case of plasma antithrombin III deficiency. Antithrombin III activity was estimated by a chromogenic assay. Hence, antithrombin III deficiency, though rare, should be considered while evaluating young patients with stroke of unknown etiology.engAdultAge of OnsetAntithrombin III Deficiency --bloodFemaleHumansIschemic Attack, Transient --bloodMiddle AgedRisk FactorsCase Reports
