ObjectivePatients with spinal metastasis (SM) are at advanced stages of systemic cancer disease. Surgical therapy for SM is a common treatment modality enabling histopathological diagnosis and the prevention of severe neurological deficits. However, surgery for SM in this vulnerable patient cohort may require prolonged postoperative intensive care treatment, which could adversely affect the anticipated benefit of the surgery. We therefore assessed postoperative prolonged mechanical ventilation (PMV) as an indicator for intensive care treatment with regard to potential correlations with early postoperative mortality and overall survival (OS).MethodsBetween 2015 and 2019, 198 patients were surgically treated for SM at the author´s neurosurgical department. PMV was defined as postoperative mechanical ventilation of more than 24 hours. A multivariate analysis was performed to identify pre- and perioperative collectable predictors for 30 days mortality.ResultsTwenty out of 198 patients (10%) with SM suffered from postoperative PMV. Patients with PMV exhibited a median OS rate of 1 month compared to 12 months for patients without PMV (p < 0.0001). The 30 days mortality was 70% and after one year 100%. The multivariate analysis identified “PMV > 24 hrs” (p < 0.001, OR 0.3, 95% CI 0.02-0.4) as the only significant and independent predictor for 30 days mortality (Nagelkerke’s R2 0.38).ConclusionsOur data indicate postoperative PMV to significantly correlate to high early postoperative mortality rates as well as to poor OS in patients with surgically treated SM. These findings might encourage the initiation of further multicenter studies to comprehensively investigate PMV as a so far underestimated negative prognostic factor in the course of surgical treatment for SM.
Study design Retrospective single-center cohort study. Background The spine is the most common anatomic site for osteoporotic fractures. Osteoporotic vertebral fractures play an increasingly important role in geriatric patients and percutaneous vertebroplasty (PVP) constitutes a common treatment option. The aim of this study was to evaluate the safety and efficacy of PVP in geriatric patients with cardiovascular comorbidities at our center. Methods In this retrospective single-center study, 49 patients aged ≥ 65 with a total of 88 vertebral fractures underwent vertebroplasty. MRI and CT scans of the spine were performed in all patients prior to surgery. All patients were evaluated 4 weeks after surgery as part of their clinical follow-up. VAS scores were recorded before and after the operation. Postoperative complications within 30 days of the initial surgery were analyzed. Results The mean age of patients was 77 years (± 6.4). Of the 49 patients, 39 (80%) were female, and 36 (76%) had cardiovascular comorbidities. The most frequent postoperative complications were cement leakage with no new neurological postoperative deficits (14.3%). The in-hospital mortality rate was 1 out of 49 patients (2%). VAS scores revealed an overall pain reduction of > 97%. None of the following affected patient safety: ASA, BMI, duration of surgery, or the level or localization of vertebroplasty. Conclusions Our data demonstrate that vertebroplasty was a feasible and effective treatment for pain reduction in geriatric patients with osteoporotic fractures despite cardiovascular comorbidities. Level of evidence 3.
ObjectiveDorsal instrumentation of the cervical spine is an established treatment in spine surgery. However, careful planning is required, particularly in elderly patients. This study evaluates early clinical outcomes in geriatric patients undergoing complex spine surgery.MethodsIn this retrospective, single center cohort study, we included all geriatric patients (aged ≥65 years) who underwent dorsal instrumentation between January 2013 and December 2020. We analyzed postoperative complications and the 30-day in-hospital mortality rate. Furthermore, the Charlson comorbidity index (CCI) and Clavien-Dindo grading system (CDG) were used to assess the patients' comorbidity burden.ResultsIn total, 153 patients were identified and included. The mean age of patients was 78 years (SD ± 7). Traumatic injury (53.6%) was the most common reason for surgery. 60.8% of the patients underwent dorsal instrumentation with 3 or more levels. The most common comorbidities were arterial hypertension (64%), diabetes mellitus (22.2%), coronary heart disease and atrial fibrillation (19.6%). The most common adverse event (AE) was pneumonia (4%) and the most common surgery-related complication was wound infection (5.2%). Among patients categorized as high risk for AE (CCI > 5), 14.6% suffered a postoperative AE. In our univariate analysis, we found no risk factors for high rates of complications or mortality.ConclusionOur data demonstrates that older patients were at no significant risk of postoperative complications. The CCI/CDG scores may identify patients at higher risk for adverse events after dorsal instrumentation, and these assessments should become an essential component of stratification in this older patient population.
