Introduction. Chronic calcified/ossified subdural hematoma is a rare diagnosis. The incidence of chronic calcified subdural hematoma is 0.3-2.7% of all chronic subdural hematomas. Surgical treatment is indicated in most cases, but there is still some controversy. Materials and Methods. We present a case report of 81-year-old woman with calcified chronic subdural hematoma. Patient underwent an osteoplastic left craniotomy, evacuation of chronic subdural mass with careful dissection andsuccessful removal of inner and outer membrane. Postoperative CT scan showed removal of subdural hematoma, decrease of left shift of median line and good brain re-expansion. Postoperative period was without any serious complications. Results. Subdural hematoma was successfully removed, resulting in a good recovery with complete resolution of patients symptoms. From our experience, we highly recommend surgical treatment in cases of chronic symptomatic calcified subdural hematomas.
Objective: Degenerative lumbar spine dis ease is an increas ing problem nowadays, aff ect ing more and more people, especial ly, the elderly population. The older age of patients is general ly associated with a higher rate of postoperative complications. Patients and methods: A retrospective analysis of patients aged 60 years or older who underwent the elective spine surgery at the Clinic of Neurosurgery at the University Hospital Martin from January 2015 to December 2016. Authors as ses sed the incidence of early postoperative complications after lumbar spine surgery in older patients and found a cor relation between comorbidities, selected risk factors and the occur rence of postoperative complications. Results: Over al l, 107 patients were as ses sed (48 men and 59 women). The incidence of postoperative complications was 24.3%. The incidence of major complications was 9.4%, the incidence of minor complications was 17.8%. 7.5% of patients needed revision surgery. 83.2% of patients underwent decompres sive surgery alone while, 16.8% of patients underwent spinal surgery with fusion. The rate of complications was higher in those patients who underwent surgery with instrumentation in comparison to the decompres sive surgery alone (23.6 vs. 27.8%; p = 0.7561). There was a statistical ly signifi cant as sociation between the presence of type 2 diabetes mel litus and the incidence of complications (p = 0.0082). The length of a surgical procedure strongly aff ected the occur rence of postoperative complications (p = 0,001). Conclusion: Almost one quarter of patients aged 60 years or older developed postoperative complications with the predominance of minor complications. The study showed an increas ing rate of complications in patients who underwent a surgical procedure with instrumentation compared to patients with decompres sive surgery only, but without statistical signifi cance. We proved an as sociation between the surgery length, the length of the hospital stay, the presence of type 2 diabetes mellitus and the presence of postoperative complications.

INTRODUCTION: Bilateral fi nding of non-acute subdural hematomas (NASH) is less common compared to unilateral occurrence. The aim of this study was to evaluate results of surgical treatment of bilaterally treated bilateral NASH. METHODS: Retrospective analysis of patients, who underwent bilateral surgical evacuation of NASH (2014)(2015)(2016)(2017)(2018)(2019)(2020). This study was conducted to determine the association between the incidence of postoperative complications and outcome, hematoma recurrence and selected risk factors (including volumetric parameters). Correlations between variables were assessed by using Spearmanˊs correlation. Chi-squared test, Studentˊs t-test (unpaired and paired) and one-way ANOVA were used for univariate analysis. RESULTS: Our study included 29 patients with bilateral NASH who underwent bilateral surgical hematoma evacuation. The laminar hematoma type was associated with higher hematoma recurrence rate (p = 0.032) and worse clinical outcome (p = 0.043). Larger PHV was signifi cantly associated with larger PV after surgery and worse neurological outcome. Larger PHV, PHCV and PV were signifi cantly associated with higher incidence of NASH recurrence (p = 0.0008, p = 0.0007 and p = 0.00006). CONCLUSION: The laminar hematoma type and larger PHV were signifi cant risk factors for the recurrence of bilateral NASH and worse neurological outcome. Larger PHCV and PV were signifi cantly associated with hematoma recurrence (Tab. 7, Fig. 3, Ref. 24).
