Objective: Chronic subdural hematoma (CSDH) is one of the most frequent neurosurgical conditions in people aging between 70 and 80 years. The cranial burr-hole (CBH) with surgical cavity irrigation through the burr hole and closed drainage system is the treatment of choice but -post-operative outcome can be influenced by pneumocephalus. In this study, we aimed to explore the relationship between the anterior-posterior (AP) burr-hole position and the volume of post-operative pneumocephalus. Patients and Methods: We identified 153 consecutive patients who underwent BHC for CSDH at our institution. Baseline and post-operative data were retrospectively collected from medical records. The linear regression model was used to estimate the association between the volume of post-operative subdural air collection and burr-hole position along with other baseline patients and hematoma variables. Results: The AP position of the burr-hole was independently associated with the volume of post-operative pneumocephalus: lower volume of subdural air was observed in patients with more anterior cranial burr-hole. Conclusions: In patients operated for CSDH, the cranial burr-hole should be performed anteriorly to grant a lesser amount of subdural post-operative air collection.

Chronic subdural hematoma is a common type of intracranial hemorrhage with higher incidence and unpredictable evolution among elderly people. We present the case of a 73 years old male patient, diagnosed in October 2013 with subacute bilateral subdural hematomas who was admitted in our clinic for worsening of motor function in his left limbs. The cerebral CT performed revealed a right massive chronic subdural hematoma which met the criteria for neurosurgical approach requiring a large craniotomy for complete removal. In this article we review the risk factors associated with an unpredictable evolution and postoperative subdural hematoma recurrence in the elderly.
