title: Removal of subarachnoid blood clots after subarachnoid hemorrhage.
abstract: The difficulty in removing subarachnoid blood clots was evaluated in terms of the interval after subarachnoid hemorrhage. Subarachnoid blood clots were removed from a total of 30 cisterns with a Hounsfield unit of more than 70. In 20 cisterns, removal was performed within 24 hours, and in 10 between 24 and 72 hours after subarachnoid hemorrhage. In 16 of the 20 cisterns (80%) and in 4 of the 10 cisterns (40%), the density was reduced to a Hounsfield unit of less than 60 after removal of subarachnoid blood clots. Two typical cases are presented.
