Second-look strokectomy of cerebral infarction areas in patients with severe herniation.
Decompressive craniectomies (DCs) are performed on patients suffering large cerebral infarctions. The efficacy of this procedure has been demonstrated in several trials. In some cases, however, this procedure alone is not sufficient and patients still suffer refractory elevations of intracranial pressure (ICP). The goal of this study was to determine whether resection of infarcted tissue, termed strokectomy, performed as a second-look procedure after DC, improves outcome in selected cases. ⋯ In this study in comparison to former studies, mortality rates were lower and clinical outcome was comparable to that of previously published trials regarding large cerebral infarctions. Second surgery including strokectomy may help achieve better outcomes, especially in cases of infarction of more than one vascular territory.

Earlier tracheostomy and percutaneous endoscopic gastrostomy in patients with hemorrhagic stroke: associated factors and effects on hospitalization.
Existing literature supports benefits of early tracheostomy and percutaneous endoscopic gastrostomy (PEG) in certain patient populations. The aim of this study was to review tracheostomy and PEG placement data in patients with hemorrhagic stroke in order to identify factors associated with earlier placement and to evaluate outcomes. ⋯ This study identified patient risk factors associated with increased likelihood of tracheostomy and PEG in patients with hemorrhagic stroke who were critically ill. Additionally, we found that the timing of tracheostomy was associated with length of ICU stay and overall hospital stay, and that the timing of PEG was associated with overall length of hospitalization. Complication rates related to tracheostomy and PEG in this population were minimal. This retrospective data set supports some benefit to earlier tracheostomy and PEG placement in this population and justifies the need for further prospective study.

Venous outflow restriction as a predictor of cavernous sinus dural arteriovenous fistula obliteration after Gamma Knife surgery.
Gamma Knife surgery (GKS) obliterates 65%-87% of cavernous sinus dural arteriovenous fistulas (CSDAVFs). However, the hemodynamic effect on GKS outcomes is relatively unknown. The authors thus used the classification scheme developed by Suh et al. to explore this effect. ⋯ GKS is an equally effective treatment option for all 3 CSDAVF types. Furthermore, the number of venous drainage routes may help in predicting treatment outcomes and making therapeutic decisions.

Combined use of minimal access craniotomy, intraoperative magnetic resonance imaging, and awake functional mapping for the resection of gliomas in 61 patients.
Current management of gliomas involves a multidisciplinary approach, including a combination of maximal safe resection, radiotherapy, and chemotherapy. The use of intraoperative MRI (iMRI) helps to maximize extent of resection (EOR), and use of awake functional mapping supports preservation of eloquent areas of the brain. This study reports on the combined use of these surgical adjuncts. ⋯ In this retrospective case series, the combined use of iMRI and awake functional mapping was demonstrated to be safe and feasible. This combined approach allows one to achieve the dual goals of maximal tumor removal and minimal functional consequences in patients undergoing glioma resection.

Secondary hemorrhagic complications in aneurysmal subarachnoid hemorrhage: when the impact hits hard.
Clinical data on secondary hemorrhagic complications (SHCs) in patients with aneurysmal subarachnoid hemorrhage (SAH) are sparse and mostly limited to ventriculostomy-associated SHCs. This study aimed to elucidate the incidence, risk factors, and impact on outcome of SHCs in a large cohort of SAH patients. ⋯ SHCs present a rare sequela of SAH. Antiplatelet therapy during (but not before) SAH increases the risk of ventriculostomy-associated bleedings, but without further impact on the course and outcome of SAH. The use of thrombolytic agents for early effective anticoagulation carries relevant risk for major SHCs and poor outcome.
