The burr-hole craniostomy and subperiosteal drain placement technique was performed in HUS
A: Burr-hole craniostomy followed with SPD placement of the corrugated Radivac catheter over the burr-hole of at least 10 mm diameter.
B: The drain was then pulled through from underneath the galea postero-laterally away from the skin incision.
C: The drain was connected to the collecting system which was placed under non-active suction pressure (passive drain) below the level of the head.
