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.

Background: Chronic subdural hematoma (cSDH) is a common neurosurgical condition, with symptoms ranging from headaches to coma. Operative evacuation is the treatment of choice. Subdural reaccumulation leading to reoperation is a vexing postoperative complication., Objective: To present a novel technique for intraoperative aspiration of pneumocephalus via a subdural drain following SDH evacuation as a method of reducing potential subdural space and promoting cerebral expansion, thereby decreasing SDH recurrence., Methods: In this retrospective study, 15 patients who underwent operative evacuation of cSDH between 2008 and 2015 were assessed. Six patients underwent a small craniotomy with intraoperative pneumocephalus aspiration. These patients were matched by age, gender, and anticoagulation status to 9 patients who underwent evacuation of SDH without pneumocephalus aspiration. Quantitative volumetric analysis was performed on the preoperative, postoperative, and 1-mo follow-up computed tomography scan to assess the subdural volume., Results: In the immediate postoperative period, there was no difference in the percentage of residual subdural fluid between the aspiration and control groups (0.291 vs 0.251; P = 1.00). There was a decrease in amount of pneumocephalus present when the aspiration technique was applied (0.182 vs 0.386; P = .041). At 1-mo follow-up, there was a decrease in the residual cSDH volume between the aspiration and the control groups (28.7 mL vs 60.8 mL; P = .011). The long-term evacuation rate was greater in the aspiration group (75.4% vs 51.6%; P = .015)., Conclusion: Intraoperative aspiration of cSDH cavity is a safe technique that may enhance cerebral expansion and reduce likelihood of cSDH recurrence., (Copyright © 2019 by the Congress of Neurological Surgeons.)

Objective: The incidence of chronic Subdural hematoma (cSDH) is increasing and its rate of recurrence varies from 5 to 33%. A postoperative brain midline-shift (MLS) on computed tomography (CT) equal or larger than 5mm is a risk factor for recurrence. Transcranial color-coded duplex sonography (TCCDS) is a noninvasive bedside reproducible technique useful to detect MLS. The aim of our study was to compare in patients affected by cSDH, the values of MLS obtained pre- and post-operatively by TCCDS and brain CT., Patients and Methods: 32 patients affected by cSDH entered the study between July 2016 and January 2017. MLS values obtained by TCCDS and brain CT were compared using Bland-Altman plot and linear regression analysis. Using the same techniques we also explored if the agreement between the two imaging modes was comparable in pre- and post-operative data pairs., Results: 64 data pairs of MLS values obtained by TCCDS and CT were analysed. Bland-Altman diagrams did not show any systematic bias of the data and linear regression indicated a significant correlation between the two measures both before and after hematoma evacuation., Conclusion: In patients affected by cSDH, MLS values obtained before and after surgery by TCCDS are comparable to those obtained by CT; TCCDS might be considered an alternative to CT scan in the management of patients after cSDH evacuation. We suggest that close clinical bedside examination and TCCDS might be appropriate for the post-operative management of cSDH, reserving CT scan only to patients with overt clinical deterioration and/or increasing MLS., (Copyright © 2017 Elsevier B.V.
