Decompressive craniectomy at the National Hospital of Niamey: Prospective study of the epidemioclinical profile, indications, surgical techniques, and results in a context of limited resources.

Background: Decompressive craniectomy (DC) is a neurosurgical technique that is gaining renewed interest due to the worldwide resurgence of head injuries. We aimed to analyze the quality of management and prognosis of patients who underwent this surgery in the context of limited resources. Methods: This was a prospective, longitudinal, descriptive, and analytical study following STROBE, lasting 36 months at the National Hospital of Niamey in patients who had undergone DC. Results: During our study, we collected 74 cases of DC. The mean age was 32.04 years (10-75 years), with male predominance (91.89%). DC was mainly performed following head trauma (95.95%), the main cause of which was road traffic accidents (76%; 54/71). On admission, most patients presented with altered consciousness (95.95%) and pupillary abnormalities (62.16%). The average time between brain damage and brain scan was 31.28 h, with parenchymal contusion being the most frequent lesion (90.54%). The majority of patients (94.59%) underwent decompressive hemicraniectomy. Postoperative complications accounted for 71.62% of all cases, with 33.78% resulting in death. Among survivors, 55.10% had neurological sequelae at the last consultation (27/49). The main factors associated with the risk of death and morbidity were a Glasgow coma score ≤8, pupillary abnormality on admission, the presence of signs of brain engagement, and a long admission delay. Conclusion: Our study shows that the impact of limited resources on our care is moderate. Future research will concentrate on long-term monitoring, particularly focusing on the psychosocial reintegration of patients post-DC.
