- Abstract
The aim of this study was to investigate the relationship between the volume of lesion (VOL) in patients with stroke and the associated length of hospital stay (LOS), as well as longer-term functional outcome. Computerised tomography (CT) scans were used to measure the volume, region and type of lesion, volume being measured by planimetry. LOS and other patient details were obtained from the Dundee Stroke Database. The total LOS was associated with the VOL on univariate analysis (p = 0.004) and after adjustment for the other variables (p = 0.006) due to a larger lesion being associated with longer stay in hospital. Patient follow-up confirmed that the VOL was also highly significant when related to functional outcome measures of impairment, disability and handicap at one year, as determined by Orgogozo (p = 0.03), Barthel (p < 0.01) and Rankin scores (p < 0.01) respectively. The VOL is related to the length of stay in hospital and outcome at one year. This is of particular interest with the increasing use of thrombolysis and development of neuroprotectant agents designed to limit VOL.
