Abstract
ObjectiveWe report the results of surgical treatment of chronic subdural hematoma in the Kipe Hospital in Conakry, Guinea, for the period July 2012 to November 2015. Material and methodClinical, radiological and therapeutic data from 22 cases were collected retrospectively and analyzed, with a mean follow-up of 61.6 days. Univariate analysis screened for factors for neurological outcome on the Markwalder Grading Scale (MGS; 0=normal to 4=coma). ResultsMale-female sex ratio was 2.6:1. Mean age at diagnosis was 71.09±8 years, with peak incidence of CSDH in the 60–79 age group. Traumatic brain injury was identified as causal in 40.9% of cases. Burrhole trepanation was used in 86.36% of cases, under local anesthesia in 76%, and with postoperative drainage in all cases. No recurrences were recorded. At follow-up, mean postoperative MGS was 0.59 (up from 3.08 preoperatively); 54.54% of patients had normal neurological examination (grade 0). Age 60–79 years, time to diagnosis>12 weeks and preoperative MGS≥3 had significant negative impact on outcome (respective P-values: 0.03, 0.001, 0.001). ConclusionOur data were similar to those of the literature, but with longer time to diagnosis and poorer initial clinical status, with negative impact on clinical progression.
