Background: A chronic subdural hematoma (CSDH) is one of the most common neurosurgery operations. This study aimed to evaluate the effect of topical corticosteroids combined with surgery in patients with CSDH. Materials and Methods: The present study is a clinical trial study on patients referred to hospitals associated with Ahvaz University of Medical Sciences with chronic subdural hematoma in 2019. Patients requiring surgical drainage of chronic subdural hematoma who met the inclusion criteria underwent open craniotomy surgery on the side of the hematoma. A drain was placed in the open craniotomy site. On the third day after the operation, before removing the drain, 40 mg of methylprednisolone sodium succinate was injected through the drain into the subdural space, after which the drain was pulled entirely. Patients were evaluated with the Markwalder Grading Scale (MGS) on the third day, third month, and sixth month after surgery for improved or worsened neurological symptoms. Also, in the third and sixth months after surgery, the patients underwent Computerized Tomography Scan imaging and were checked for recurrence. Results: 32 patients with CSDH entered the study, including 28 men and four women, with a mean age of 71.62 ± 9.85 years. Moreover, 87.5 % had a unilateral chronic subdural hematoma (uCSDH), and 12.5 % had a bilateral chronic subdural hematoma (bCSDH). Left and right uCSDHs had the same frequency (43. 8 %). After surgery, 26 patients had no postoperative complications, and six patients experienced pneumocephalus. Conclusion: Topical dexamethasone injection through the potential CSDH cavity can result in desirable outcomes.

Background There is an increasing incidence of chronic subdural hematoma due to extended life expectancy and associated trauma and fall risk. This retrospective study evaluates the efficacy of two burr-hole craniotomy over mini-craniotomy. Methods Sixty-five patients were recruited over 2 years, of which 56 were male and 9 were females. A patient with a chronic subdural hematoma either underwent burr-hole craniostomy or mini-craniotomy for hematoma evacuation. Glasgow coma scale (GCS) and modified Rankin score were used to assess the neurological status and interventional outcome at discharge and follow-up, respectively. A head CT scan was performed at 3 week and 3 month follow-up. Statistical Analysis Categorical data are presented as frequency and percentage, while non-categorical data are represented as mean ± SD. Statistical significance for difference in outcome between the two groups was analyzed using the chi-square test and p -value less than 0.05 was considered statistically significant. Results The mean age of patients was 55.6 years. Headache (35 cases), hemiparesis, and altered sensorium were seen in 20 patients, each with the main presenting symptoms. Trauma history was noted in 69.2% of patients. One (3.7%) hematoma recurrence in the burr-hole group and four (8.3%) in the mini-craniotomy group was recorded. The mean operative time was longer in the minicraniotomy group (124.2 min vs. 75.4 min; p < 0.001). A higher incidence of recurrence was noted in the craniotomy group (8.3%) than the burr-hole group (3.7%). No statistical difference in the recurrence rate, duration of hospital stay, GCS at discharge, modified Rankin score between the two study groups at discharge was noted. Conclusion Two burr-hole craniostomy is a safe and effective surgical option to treat chronic subdural hematoma. It is also validated in patients on anticoagulants and antiplatelet medications with adequate pre-surgical correction of coagulation parameters. [ABSTRACT FROM AUTHOR]

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.

Background Factors determining the recurrence of chronic subdural hematomas (CSDHs) are not clear. Whether opening the so-called internal hematoma membrane is useful has not been investigated. Objective To investigate whether splitting the inner hematoma membrane influences the recurrence rate in patients undergoing burr-hole craniotomy for CSDH. Methods Fifty-two awake patients undergoing surgery for 57 CSDHs were prospectively randomized to either partial opening of the inner hematoma membrane (group A) or not (group B) after enlarged burr-hole craniotomy and hematoma evacuation. Drainage was left in situ for several days postoperatively. Groups were comparable with regard to demographic, clinical, and imaging variables. Outcome was assessed after 3–6 weeks for the combined outcome variable of reoperation or residual hematoma of one third or more of the original hematoma thickness. Results Fourteen patients underwent reoperation for clinical deterioration or residual hematoma during follow-up ( n = 6 in group A, 21%; n = 8 in group B, 28 %) ( P = 0.537). Residual hematoma of ≥ one third not requiring surgery was present in 7 patients in group A (25%) and 10 patients in group B (36%) ( P = 0.383). The overall cumulative failure rate (reoperation or hematoma thickness ≥ one third) was 13/28 (46%) in group A and 18/28 in group B ( P = 0.178; relative risk, 0.722 [95% confidence interval, 0.445–1.172]; absolute risk reduction –16% [95% confidence interval, –38% to 8%]). Conclusions Opening the internal hematoma membrane does not alter the rate of patients requiring revision surgery and the number of patients showing a marked residual hematoma 6 weeks after evacuation of a CSDH.

Objective To determine whether the use of a subdural drain after burr-hole evacuation of a chronic subdural hematoma is safe and effective in preventing recurrence and subsequent operations, and as such improving functional outcomes. Methods The literature search included the following databases: PubMed, the National Institutes of Health/National Library of Medicine, Clinical Trials Registry, CENTRAL (The Cochrane Library), EMBASE, and LILACS. The search was performed in June 2013, and did not have restrictions or filters with regard to language or year of publication. Methodologic quality was assessed through the Jadad's scale. Primary outcomes were recurrence and reoperation rates. Secondary outcomes were functional outcome, mortality, and postoperative complications. Results were presented as pooled Mantel-Haenszel relative risks (RR), with 95% confidence intervals (95% CI). Results A total of 7 randomized controlled trials were analyzed. Three studies were classified as high methodologic quality and four as low quality. Pooled RR were symptomatic recurrence (RR 0.51; 95% CI 0.36–0.75), reoperation (RR 0.5; 95% CI 0.34–0.74), poor functional outcome (RR 0.61, 95% CI 0.39–0.98), mortality (RR 0.67, 95% CI 0.37–1.22), and postoperative complications (RR 1.28, 95% CI 0.78–2.11). There was no statistically significant heterogeneity within the outcomes. Conclusions The meta-analysis demonstrates that the insertion of a subdural drain was associated with a statistically significant reduction in the risk of symptomatic recurrence and the requirement for further surgical intervention of chronic subdural hematoma after surgical evacuation. Furthermore, it was associated with statistically significant improvements in both short-term and long-term functional outcome. [ABSTRACT FROM AUTHOR]

Objective : To analyze the clinical data and surgical results from symptomatic chronic subdural hematoma (CSDH) patients who underwent burr-hole drainage (BHD) at the maximal thickness area and twist-drill craniostomy (TDC) at the precoronal point. Methods : We analyzed data from 65 symptomatic CSDH patients who underwent TDC at the pre-coronal point or BHD at the maximal thickness area. For TDC, we defined the pre-coronal point to be 1 cm anterior to the coronal suture at the level of the superior temporal line. TDC was performed in patients with CSDH that extended beyond the coronal suture, as confirmed by preoperative CT scans. Medical records, radiological findings, and clinical performance were reviewed and analyzed. Results : Of the 65 CSDH patients, 13/17 (76.4%) with BHD and 42/48 (87.5%) with TDC showed improved clinical performance and radiological findings after surgery. Catheter failure was seen in 1/48 (2.4%) cases of TDC. Five patients (29.4%) in the BHD group and four patients (8.33%) in the TDC group underwent reoperations due to remaining hematomas, and they improved with a second operation, BHD or TDC. Conclusion : Both BHD at the maximal thickness area and TDC at the pre-coronal point are safe and effective drainage methods for symptomatic CSDHs with reasonable indications. [ABSTRACT FROM AUTHOR]
