Objective: To identify the factors associated with recurrence in patients undergoing chronic subdural hematomas at the University Hospital Mayor. Methods: Observational, analytical study of a cohort with retrospective information collection, in which the review of clinical histories and images by tomography of patients underwent surgery for chronic subdural hematomas will be carried out, in the Hospital Universitario Mayor- Méderi between 2014 to 2017. Results: During the study period, 88 chronic subdural hematomas were underwent surgery, in a total of 299 patients, of which there were 24 (8%) recurrences of chronic subdural hematomas, of these recurrences 3 (1%) presented more than two interventions. The following factors associated with recurrence were found: massive air collection OR 3.74 CI 95% (3.68-4.9), obliterated cisterns 1.37 CI 95% (1.13- 4.84), trabeculated architecture 1.19 CI 95% (1.18- 9.03), midline shift > 10 mm 1.10 CI 95% (1.02- 5.93) and the pre-surgical volume of the hematoma 1.01 CI 95% (1.00-1.02). Conclusions: In our environment, the appearance of chronic subdural hematomas associated with the aging of the population is becoming more frequent, implying a challenge for the coming years in public health issues; since up to 8% of the patients in this study presented recurrences, which were associated with longer hospital stays and medical complications, predominantly infectious. By recognizing the factors associated with recurrence in this population, we can act in a more timely manner, avoiding an over-cost to the health system and fundamentally an impact on the functionality of the patient and his family.
