文摘

Branch atheromatous disease (BAD) is differentiated from lacunar infarction (LI). BAD is often associated with neurological deterioration in the acute stage, but outcome of BAD patients in the chronic stage is unclear. We aimed to explore the outcome of BAD in the lenticulostriate artery (LSA) territory in comparison with those of LI from the viewpoint of activities of daily living (ADLs).

Methods

We retrospectively investigated patients who were admitted within 3 days after stroke onset. The patients underwent daily rehabilitation during hospitalization. BAD in LSA territory was defined by the presence of lesion representing 3 or more consecutive horizontal slices in magnetic resonance imaging. Patients having atrial fibrillation or more than 50% stenosis of the large artery in magnetic resonance angiography were excluded. We retrieved data on clinical characteristics and evaluation from medical records.

Results

Subjects were 41 BAD and 35 LI patients. There was little difference in baseline characteristics. The National Institutes of Health Stroke Scale score was significantly higher in BAD patients (P < .05). The Barthel Index (BI) score and the Brunnstrom recovery stage were lower in BAD patients at admission (P < .05 and P < .05). Hospital stay was longer in BAD patients (P < .01), but the BI score at discharge was not different. To ambulate, 8 BAD and 1 LI patients depended on orthoses (P < .05), and 21 BAD and 7 LI patients used canes (P < .01). Multivariable analysis demonstrated that BAD lesion was correlated with AFO use independent of age and sex.

Conclusions

BAD patients can obtain ADLs similar to LI patients. However, many BAD patients require canes and/or orthoses.
