FIELD: medicine.

SUBSTANCE: method involves clipping aneurysms and setting two catheters into chiasmatic cistern and into internal carotid artery cistern. After having finished the operation, liquor is discharged concurrently from chiasmatic cistern and internal carotid artery cisterns in the amount of 5-7 ml at a rate of 30-40 ml/h. Two F90PvB Portex filters are sequentially attached to each catheter and the collected liquor is introduced at a rate of 30-40 ml/h and filtered. The cycle is repeated until one volume of circulating liquor is filtered. The process is repeated 6 h later in taking one filter off from each catheter and liquor filtration is continued through one filter. The liquor filtration sessions are repeated every other day depending on subarachnoid hemorrhage intensity. Total liquor filtration treatment is not to last more than 96 h long.
