Abstract
BACKGROUND Chronic subdural hematomas (CSDHs) are common in the elderly, with a relatively high rate of recurrence after initial surgical intervention. Our research team previously created a predictive grading system, the Puerto Rico Recurrence Scale (PRRS), to identify patients at high risk of CSDH recurrence. In this study, we introduce a modification of the (mPRRS) that includes pneumocephalus volume, which has been independently associated with recurrence. METHODS A single-center Puerto Rican population-based retrospective study was performed to analyze data for patients treated for CSDH at 1 institution between July 1, 2017, and December 31, 2019. Univariate and multivariate analyses were used to create a grading scale predictive of recurrence. Retrospective validation was conducted for the cohort. RESULTS Of 108 patients included in the study, 42 had recurrence, and 66 had nonrecurrence. Postoperative subdural space, postoperative midline shift, and pneumocephalus volume were all higher with recurrence (P = 0.002, P = 0.009, and P < 0.001, respectively). Multivariate analysis was used to create a 6-point grading scale comprising 3 variables (pneumocephalus volume [< 10, 10-20, 21-30, and > 30 cm3], postoperative midline shift [< 0.4, 0.41-1.0, and > 1.0 cm], and laterality [unilateral and bilateral]). Recurrence rates progressively increased in low-risk to high-risk groups (2/18 [11%] vs 21/34 [62%]; P < 0.003). CONCLUSION The mPRRS incorporating pneumocephalus measurement improves CSDH recurrence prediction. The mPRRS indicated that patients with higher scores have a greater risk of recurrence and emphasized the importance of measuring postoperative variables for prediction. The mPRRS grading scale for CSDHs may be applicable not only to the Puerto Rican population but also to the general population.

Gender-Specific Differences in Chronic Subdural Hematoma. J Craniofac Surg 2023; 34:e124-e128. [PMID: 36857560 DOI: 10.1097/scs.0000000000008855] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Accepted: 06/06/2022] [Indexed: 03/02/2023] Open
Abstract
OBJECTIVE Few studies concerning aspects of gender-specific differences in chronic subdural hematoma (CSDH). This study aimed to determine whether gender-specific differences exist in CSDH regarding clinical, radiological characteristics, and prognosis. METHODS A total of 585 patients with CSDH were retrospectively identified. Patients were divided into 2 groups based on gender. Clinical, radiological characteristics, and prognosis were compared using Fisher's exact test or Student t test when applicable. The logistic regression model was used to identify independent risk factors associated with death in CSDH patients. The receiver operating characteristic curve was used to detect the sensitivity and specificity of independent risk factors. RESULTS The average age of women was 71.50±0.92 years, significantly older than 67.30±0.60 years in men. Hypertension, diabetes mellitus, and uremia were significantly more common in women than in men. Alcohol intake was more in males than in females. CSDH patients in males manifested homogeneous iso-dense and homogeneous hyper-dense was obviously more than that in the females. Although homogeneous hypo-dense and mixed density were significantly more common in the females. The average preoperative hematoma volume of the unilateral CSDH in males was 160.85±3.06 cm3, significantly more than 139.60±5.70 cm3 in females. The mortality of females was 7.4%, higher than 1.7% in males (P=0.004). Female, age, uremia, and recurrence were independent risk factors for death in CSDH patients. CONCLUSIONS Gender-specific differences do exist in CSDH. Female, age, uremia, and recurrence were independent risk factors for death in CSDH patients.

Acta Neurochir (Wien) 2021; 163:1849-1856. [PMID: 33796888 PMCID: PMC8195919 DOI: 10.1007/s00701-021-04811-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Accepted: 03/16/2021] [Indexed: 11/13/2022]
Abstract
Background Chronic subdural haematoma (CSDH) is one of the most common neurosurgical diseases. A subtype of CSDH is bilateral chronic subdural haematoma (bCSDH) which represents 20–25% of patients with CSDH and has a higher recurrence rate. There is no clear consensus on how bCSDH should be treated regarding upfront unilateral- or bilateral evacuation of both haematomas. The purpose of this study was to identify risk factors associated with reoperation of bCSDH. Methods A total of 326 patients with radiological evidence of bCSDH were included in this retrospective cohort study where 133 (40.8%) patients underwent primary bilateral evacuation and 193 (59.2%) primary unilateral evacuation. The two centres operated using different surgical approaches. Analyses were performed to identify risk factors associated with reoperation of bCSDH. Reoperation rate was defined as reoperation of CSDH on either side of the hemisphere within 3 months after primary evacuation. Results The cohort had a total reoperation rate of 26.4%. Patients which underwent unilateral evacuation had a reoperation rate of 32.1%, and the bilateral group had a reoperation rate of 18.0% (p=0.005). Multivariable logistic regression identified unilateral evacuation (OR 1.91, p=0.022) and complications according to Ibanez (OR 2.20, p=0.032) to be associated with the need of reoperation of bCSDH. One-burr hole craniostomy with active subgaleal drain was primarily performed in bilateral approach (69.4%) whereas patients operated with minicraniotomy with passive subdural drain were primarily operated by unilateral evacuation of the larger symptomatic side (92.8%). Conclusions Unilateral evacuation of bCSDH was associated with a higher risk for reoperation than upfront bilateral evacuations in this study. There is a need to further discuss the criteria for uni- or bilateral evacuation since patients are treated differently at different centres.
