Kissing aneurysms are situated on the same artery but have separate points of origin. Open surgical strategies for access from opposing directions may be technically problematic. Recent advances in protective devices and coiling techniques have compelled the present study, aimed at technical aspects and procedural outcomes of coil embolization in this setting. ⋯ Strategies for endovascular treatment of kissing aneurysms rely heavily on characteristics that the paired aneurysms display. Properly conducted single-stage coil embolization is a safe and effective method of treating such lesions.

The impact of the COVID-19 pandemic on spine surgery in central Europe: A questionnaire-based study.
The severe acute respiratory coronavirus 2 (SARS-CoV2) crisis led to many restrictions in daily life and protective health care actions in all hospitals to ensure basic medical supply. This questionnaire-based study among spinal surgeons in central Europe was generated to investigate the impact of coronavirus disease 2019 (COVID-19) and consecutively the differences in restrictions in spinal surgery units. ⋯ The COVID-19 pandemic resulted in comparable restrictive measures for spinal surgical departments in central Europe. Elective surgical interventions were reduced, providing additional resources reserved for severe acute respiratory coronavirus 2-positive patients. Although similar restrictions were introduced in most participants' departments, the supply of personal protective equipment and the outpatient care remained insufficient and should be re-evaluated intensively for future global health care crises.

The role of continuous hypertonic saline (HS) infusion in the management of malignant cerebral edema is controversial. We evaluated patients presenting with large anterior circulation territory infarcts and compared radiographic and clinical outcomes to evaluate the effects of continuous HS. ⋯ Despite the widespread use of continuous HS in acute ischemic infarcts, only a limited number of studies have evaluated its efficacy, and virtually no studies have studied its effect on radiographic progression and rates of decompressive surgery. Results of this study indicate that there is no benefit of continuous HS. In fact, there may be worsening of cerebral edema with administration of continuous HS. In addition, there are no differences in prevention or delay of decompressive surgery or in overall mortality.

Radiographic characterization of Chiari malformation (CM) has historically focused on caudal tonsillar herniation (CH) below the foramen magnum. Previously, we published evidence linking ventral tonsillar herniation (VH) and medullary symptoms in very young children. We sought to extend that investigation by studying the radiographic and clinical significance of VH in adults diagnosed with CM. ⋯ VH is relatively common in CM patients and might be an important independent radiographic metric to evaluate and consider as part of the decision-making process, especially in those presenting with Chiari-like symptomatology referable to the medulla but who do not meet the traditional criteria of cerebellar ectopia greater than 5 mm.

Clinical features of pineal parenchymal tumors of intermediate differentiation (PPTID): A single institution series.
Pineal parenchymal tumors of intermediate differentiation (PPTID) are rare tumors of the pineal gland. Their treatment is often heterogeneous due to the lack of literature to compile standardized treatments. Although no single institution has large numbers of cases, our experience has been that the clinical course is more varied and complicated than reported. ⋯ Herein, we report clinical patterns of disease progression and treatment patterns of PPTID. Many patients progressed during the follow-up period. Disseminated disease was the most common presentation at recurrence. Ultimately, given the risk of recurrence and dissemination at recurrence, more aggressive treatment strategies should be considered. Specifically, our series suggests a benefit of adjuvant radiation at initial diagnosis for grade II patients.
