Chronic subdural haematoma--a comparison of two different treatment modalities.
Burr-hole craniotomy (BHC) and closed-system drainage undoubtedly is currently the most accepted treatment offered in chronic subdural haematoma (CSDH). Although twist-drill trephination (TDT) techniques have been available for years, now a special subdural catheter kit has been launched for treatment of CSDH. In a prospective study, 33 patients with 36 CSDH were treated with a 5-mm TDT regimen and insertion of a CORDIS subdural catheter (CORDIS Corp., Miami, USA). The results are compared with a consecutive series of 33 patients treated previously with an 11-mm BHC and closed-system drainage for 40 CSDH: Recurrence and persistence rate of CSDH treated with TDT necessitating a second intervention was 18.1%, no further surgical intervention was necessary. In BHC treated patients, 33.3% of haematomas had to be reoperated on, another 6.0% had to be re-operated on a third time. Infection rate in BHC treated patients was 18.1% as compared with a 0% infection rate in patients treated with the TDT technique. Mortality rate for the BHC method was 9.0% as compared with 6.0% in the TDT treatment regimen. Significantly better clinical results are achieved using the TDT technique with insertion of a special subdural catheter, making this procedure superior to the BHC regimen.
