D-dimer >2.785 μg/ml and multiple infarcts ≥3 vascular territories are two characteristics of identifying cancer-associated ischemic stroke patients.

Background: The patterns and mechanisms underlying stroke in cancer patients differ from those of the conventional etiology. In this study, we further investigated the characteristics distinguishing cancer-associated ischemic stroke (CAIS) and the relationship of D-dimer value with CAIS.

Methods: Sixty-one acute ischemic stroke patients with cancer (cancer group) and 76 stroke patients without cancer (control group) were recruited.
