The aim of this case series was to provide a modern cohort of patients with cerebral aspergillosis and show the effectiveness of modern treatment concepts. In a 10-year period from January 2009 to January 2019, we identified 10 patients (6 male, 4 female) who received surgery or frameless stereotactic drainage of a cerebral aspergilloma at our center. Patients’ and disease characteristics were recorded. The median age was 65 (range 45 to 83). We conducted 133 cranial surgeries in 100 patients due to cerebral brain abscess (BA) during that time, which leads to a percentage of 10% of aspergilloma within BAs in our patient sample. We performed 3.1 surgeries per patient followed by antifungal treatment for 6 months (= median) according to the microbiological findings. Regarding comorbidities, the mean Charlson comorbidity index (CCI) at the time of admission was 5, representing an estimated 10-year survival of 21%. Six (60%) of 10 patients showed conditions of immunosuppression, one suffered endocarditis after replacement of aortic valves. Four patients showed associated frontobasal bone destruction, mycotic aneurysms, or thromboses. The mean duration of hospital stay was 37 days. Mortality was much lower than in literature. Sixty percent of the patients died during the follow-up period. The outcome of the two immunocompetent patients was more favorable. Cerebral aspergillosis is a rare, but still life-threatening, condition, which predominantly occurs in immunosuppressive conditions. Due to radical surgical and antifungal therapy for several months, mortality can be reduced dramatically.

Demographic trends make it incumbent on spine surgeons to recognize the special challenges involved in caring for older patients. The aim of this study was to identify variables that may predict early mortality in geriatric patients over the age of 90 following elective hospitalization for various spinal pathologies. Retrospective analyses of all patients over the age of 90 years, which were electively treated between 2006 and 2016 at out department for various spinal conditions, were performed. Patient characteristics, type of treatment, and comorbidities were analyzed with regard to the 30-day mortality rate. Twenty-six patients were identified. Mean age was 93 years (range 91–97), 19 (73%) were female. Eighteen (69%) patients were treated operatively. Mean hospital stay was 13 days (range 2–51). Seventeen (65%) patients were on anticoagulation therapy. Mean Charlson Comorbidity Index (CCI) was 5.3 (range 1–11); mean diagnosis count (DC) was 8.3 (range 2–17); mean Geriatric Index of Comorbidity (GIC) was 2.8 (range 1–4); and mean comorbidity-polypharmacy score (GPS) was 13.3 (range 5–23). The 30-day mortality rate was 16.7% in the surgically treated group compared with 12.5% in the conservatively treated group (p = 0.9), anticoagulation therapy (p = 0.91), gender (p = 0.49), length of hospital stay (p = 0.33), GIC (p = 0.54), CCI (p = 0.74), GPS (p = 0.82), and DC (p = 0.65) did not correlate with the 30-day mortality rate. Cause of death was pulmonary embolism in two cases and unknown in one case. Thirty-day mortality rate in patients over 90 years old with degenerative spinal diseases is relatively high regardless of the treatment modality. Standard geriatric prognostic scores seem less reliable for these patients.

Cranioplasty following decompressive craniectomy is of low surgical complexity, so much so that it has become the “beginners” cranial case. However, these “simple” procedures may have high complication rates. Identification of specific risk factors would allow targeted intervention to lower the complication rates. The aim of this study was to assess the rate of complications and to evaluate potential risk factors. We conducted a review of all patients who underwent cranioplasty in our center following decompressive craniectomy for stroke or brain trauma between 2009 and 2016. One hundred fifty-two patients were identified. Fifty-three percent were male. Mean age was 48 (range 11–78). Median time from craniectomy until cranioplasty was 102 days (range 14–378). The overall rate of complications, such as postoperative bleeding, seizures, postoperative infection, and hydrocephalus, was 30%. The mortality rate was 1%. None of the following potential risk factors was associated with significantly increased risk of periprocedural complications: gender (p = 0.34), age (p = 0.39), cause of initial surgery (p = 0.08), duration of surgery (p = 0.59), time of surgery (0.24), surgical experience (p = 0.17), and time from craniectomy until cranioplasty (p = 0.27). The 30-day complication rate following cranioplasty is high, but serious permanent deficits from these complications were rare. We found no clear predictor for these 30-day complications, which renders its prevention difficult.
