Clinical Factors Associated with Deep Vein Thrombosis in Rehabilitation Patients Suspected of Thromboembolism after Cerebral Infarction

The aim of this study is to investigate the association between characteristics of cerebral infarction lesion (vascular territory, etiology, and size), functional status and the occurrence of thromboembolism in patients suspected of having thromboembolism in a rehabilitation setting after cerebral infarction. Cerebral infarction patients who were suspected of having thromboembolism and who had undergone deep vein thrombosis (DVT) evaluation were included in analyses. Of the total 916 cerebral infarction patients, 65 patients were suspected of having DVT; 27 patients belonged to the DVT group and 38 patients belonged to the non-DVT group. The DVT (+) group was more likely to have a higher ratio of female, previous DVT history, middle cerebral artery (MCA) infarction, large arterial disease, modified Rankin Scale (mRS) score 5, abnormal speech and higher D-dimer. In multivariate logistic regression analysis, female sex, MCA infarction and mRS score 5 were significantly associated with the occurrence of thromboembolism in patients suspected of having thromboembolism. In contrast, other functional status, cerebral infarction etiology (Trial of ORG 10172 in Acute Stroke Treatment [TOAST] classification), and infarct volume were not associated with the occurrence of thromboembolism. In this study, female gender, MCA infarction, and mRS score 5 could be potential risk factors for thromboembolism in rehabilitation patients after cerebral infarction.
