Abstract

INTRODUCTION: Transcranial duplex sonography (TDS) showed good correlation with CT scan measuring bleeding extent in acute phase in patients with intracerebral haemorrhage (ICH). Our aim was to correlate ICH volumes measured by TDS and CT scan in patients with ICH on admission and after 48 hours and its relation with prognosis. METHODS: Prospective study of patients with supratentorial ICH evaluated within 24 hours of onset. All patient underwent CT scan and TDS exam on admission and at 48 hours. Hematoma volume was determined using the formula (longitudinalXsagittalXcoronal)/2 in both techniques. Association of ICH volume measured by TDS with outcome at 3 month by modified Rankin Scale was evaluated. RESULTS: Thirty-eight patients were included. ICH was measured by TDS in 27 cases due to the lack of transtemporal window. Mean age was 64 year-old and 12 (46.2%) were male. Admission mean ICH volume by CT scan was 27.4 cc (SD 30.1) and 36.4 cc (SD 37.5) by DTS with excellent correlation r=0.823 (p<0.001). Mean ICH volume measured by TDS was 25.7 (SD 24.7) in independent patients at 3 month and 66.9 (SD 46.5) in dependent group (p=0.008). Mean ICH volume at 48 hours by CT scan was 24.8 cc (SD 24.2) and by DTS 29.0 cc (SD 30.6) with very good correlation r=0.767 (p<0.001). CONCLUSION: TDS showed an excellent correlation with CT scan measuring ICH volume on admission and very good correlation within the first 48 hours. This non-invasive technique may be helpful to monitoring ICH at bedside and predicting outcome.
