Fig. 1From: Bedside transcranial sonography monitoring in a patient with hydrocephalus post subarachnoid hemorrhage a TCS using hand-held pocket ultrasound device (GE Vingmed Ultrasound AS, Horten, Norway). b Prior to EVD closure, TCS showed a measurement of the 3rd ventricle at around 1.16 cm. c On the third day, TCS showed a dilated 3rd ventricle measuring 1.37 cm. d CT scan showed a dilated 3rd ventricle measuring 13.1 mm. e Subsequently following EVD re-opening, on the next day using TCS the 3rd ventricle dimension was reduced to 0.99 cm. f The following day it went down to 0.69 cmBack to article page
