The authors evaluate a group of 92 patients with the diagnosis of chronic subdural haematoma confirmed by CT. All patients were operated from two trepanation bores with insertion of drainage into the subdural space and its connection with the closed drainage system. They used three types of drainage systems. The best clinical results were obtained with the negative pressure suction system of Braun Co in 92%. This system was switched on intermittently only till the patient developed signs of headache. Attention is focused on possible types of complications in different systems. In the remaining 13 patients who did not improve reinsertion of the drain was used, or craniotomy with membranectomy with a 60% improvement. The mentioned negative pressure drainage system in treatment in chSDH seems most suitable and is associated with the least number of complications.
