[Acute care of patients with bacterial meningitis]. / Akutversorgung von Patienten mit bakterieller Meningitis.

BACKGROUND: Bacterial meningitis is a life-threatening emergency that is still associated with high mortality and poor outcome. OBJECTIVE: The purpose of this article is to provide a review of clinical presentation, diagnostic procedure, therapy, and prognosis in bacterial meningitis. Prognostic factors which could be influenced positively are identified and a focused procedure in the emergency setting and for the treatment of complications are provided. MATERIAL AND METHODS: This work is based on a literature search (PubMed, guidelines) and personal experience (standard operating procedures, SOP). RESULTS: Despite improved health care, bacterial meningitis is still associated with high mortality and poor neurological outcome, which has remained largely unaltered during recent decades. Diagnosis and, more importantly, effective therapy of bacterial meningitis are often delayed, having an immediate negative influence on clinical outcome. Neurological and nonneurological complications often necessitate intensive care and may occur rapidly or in the further course of the disease. CONCLUSION: Immediate initiation of effective therapy is crucial to positively influence mortality and neurological outcome. Antibiotics should be administered within 30 min after admission. To achieve this, a focused and well-organized procedure in the emergency setting is necessary. Because of intra- and extracranial complications, patients need to be treated on intensive care units including neurological expertise and interdisciplinary support.

Stent Retriever Thrombectomy in Patients Who Are Ineligible for Intravenous Thrombolysis: A Multicenter Retrospective Observational Study.

BACKGROUND AND PURPOSE: Intravenous thrombolysis with rtPA is the standard of care for patients with acute ischemic stroke within 4.5 hours after symptom onset. However, a considerable number of patients are ineligible for IV thrombolysis due to various contraindications. Recent studies have proved the superiority of mechanical thrombectomy for patients with large-vessel occlusions in combination with IV rtPA compared with IV rtPA alone. We aimed to demonstrate the efficacy of mechanical thrombectomy for patients who are ineligible for IV rtPA. MATERIALS AND METHODS: Patients from the stroke registries of 4 dedicated centers who were treated with mechanical thrombectomy from January 2010 to October 2014 were retrospectively evaluated. Inclusion criteria were the following: acute stroke due to proved large-artery occlusion, ineligibility for IV thrombolysis, and a timeframe of ≤4.5 hours between stroke and the start of mechanical thrombectomy. Recanalization success, periprocedural complications, clinical outcome, and hemorrhages were evaluated. RESULTS: One hundred thirty endovascular recanalization procedures were identified. The locations were the following: proximal ICA in 17 (13.1%), terminus ICA in 25 (19.2%), M1 segment in 77 (59.2%), and M2 segment in 11 (8.5%). TICI 2b/3 results were achieved in 101 (77.7%), and an mRS score of 0-2 in 47 patients (37.9%). There was a significant correlation between TICI 2b/3 results and good clinical outcomes (87.2% versus 6.8%; P = .048). A good clinical result was most frequent when recanalization was achieved within 4.5 hours (37/74 = 50% versus 10/50 = 20.0%; P = .001). Symptomatic hemorrhage occurred in 13.1% of patients; mortality was 24.2%. Periprocedural complications were recorded in 10 patients (7.7%). CONCLUSIONS: Mechanical thrombectomy can achieve good clinical outcomes in patients with acute large-artery occlusion ineligible for IV thrombolysis, in particular when recanalization is reached early.

Mechanical thrombectomy in tandem occlusion: procedural considerations and clinical results.

INTRODUCTION: Acute tandem occlusions of the cervical and distal internal carotid artery (ICA) or middle cerebral artery (MCA) are associated with major stroke with intravenous (i.v.) thrombolysis alone in approximately 90 % of patients. The data on endovascular management of tandem occlusions is still limited. The purpose of this study was to review technical aspects and the current state of the literature on acute ICA stenting in combination with stent retriever-based intracranial thrombectomy. METHODS: We retrospectively reviewed the data of 37 consecutive patients with tandem occlusions including clinical parameters, angiographic results, procedural aspects, complications, and hemorrhages. RESULTS: Median National Institutes of Health Stroke Scale (NIHSS) on admission was 17 (3-30). Intracranial thrombectomy was performed prior to ICA stenting in 25/37 (67.6 %) and after stenting in 12/37 (32.4 %) patients. ICA stenting was successful in all cases, and a thrombolysis in cerebral infarction (TICI) scale 2b/3 result was achieved in 27/37 (73 %) cases. The mean angiography time was significantly shorter in the "thrombectomy first" group (43.1 ± 30.8 vs. 110.8 ± 43.0 min, p < 0.001), and more patients had favorable outcomes after 3 months (13/25 = 52.0 vs. 4/12 = 33.3 %, p = 0.319). In this group, intermediate catheters were used and successfully prevented embolism to unaffected territories in all cases. CONCLUSION: Acute stenting of the cervical ICA in combination with intracranial thrombectomy was technically feasible and safe in our series. Thrombectomy prior to proximal stenting was associated with shorter reperfusion times and a tendency towards better clinical outcome leading to a good outcome in about 50 % of the patients. Therefore, we recommend this approach in tandem occlusion requiring stent angioplasty.
