ReviewSurgical anatomy of the sacral hiatus for caudal access to the spinal canal.
The sacral hiatus is used for access to the spinal canal in many neurosurgical and anesthesiologic procedures. The aim of the present paper is to give a review of its anatomical characteristics relevant to permit correct and uncomplicated accesses. ⋯ The mean sacral space depth has been observed to be 4.6 mm in adults and 3.5 mm in infants. On the basis of anatomical measurements of the sacral hiatus, lower insertion angles have been suggested in infant with respect to adult subjects (21° vs. 58°).

Comparative StudyDecompressive hemi-craniectomy is not necessary to rescue supratentorial hypertensive intracerebral hemorrhage patients: consecutive single-center experience.
A consensus on decompressive surgery for hypertensive intracranial hemorrhage (ICH) has not been reached. We retrospectively analyzed our single-center experience with ICH. ⋯ Decompressive craniectomy is not necessary for rescue in ICH if the hematoma can be removed completely.

Clinical TrialIntravascular hypothermia for acute hemorrhagic stroke: a pilot study.
The use of intravascular hypothermia in the treatment of hemorrhagic stroke is currently still being researched. The exact therapeutic properties and effect of hypothermia on the natural progression of the disease are not known, and a only small number of papers has been published with results from these studies. Mild hypothermia at 34°C was induced in six patients with hemorrhagic stroke in the first 48 h after presentation, using an intravascular catheter placed in the inferior vena cava. ⋯ The patients were then followed up using the modified Rankin Scale (mRS) for 6 months and 1 year. There was a statistically significant improvement at 6 months and 1 year follow-up using the mRS score in the hypothermia group, indicating a possible beneficial effect of early therapeutic hypothermia in the management of acute hemorrhagic stroke. However, a larger study is needed in order to confirm our finding.

Chronic subdural hematoma (CSDH) is a common neurosurgical condition that has a high incidence in the increasing elderly population of many countries. Pathologically, it is defined as a persistent liquefied hematoma in the subdural space more than 3 weeks old that is generally encased by a membraneous capsule. CSDHs likely originate after minor head trauma, with a key factor in its development being the potential for a subdural cavity to permit its expansion within, which is usually due to craniocerebral disproportion. ⋯ Current belief is that CSDH arises from recurrent bleeding in the subdural space, caused by a cycle of local angiogenesis, inflammation, coagulation and ongoing fibrinolysis. However, because of a lack of detailed knowledge about the precise mechanisms, treatment is often limited to surgical interventions that are invasive and often prone to recurrence. Thus, it is possible that an easily reproducible and representative animal model of CSDH would facilitate research in the pathogenesis of CSDH and aid with development of treatment options.

The main goal of improving pain and neurological deficit in the practice of spine surgery is changing for a more ambitious goal, namely to improve the overall quality of life and the future of patients through three major actions (1) preserving the vertebral anatomical structures; (2) preserving the paravertebral anatomical structures; and (3) preserving the functionality of the segment. Thus, three new concepts have emerged (a) minimal surgery; (b) minimal access surgery; and (c) motion preservation surgery. These concepts are covered in a new term, minimally invasive spine surgery (MISS) The term "MISS" is not about one or several particular surgical techniques, but a new way of thinking, a new philosophy. ⋯ In most cases, the only evidence one can find in the literature is the lack of evidence (Resnick D (2007) Spine 32:S15-S19.), however, the lack of evidence does not mean its absence. Only then, with a rigorous self-analysis, we may take a clear path towards a new philosophy in spine surgery. Of course, feedback from patients through satisfaction and clinical scales can guide our direction and provide the energy needed to maintain the enthusiasm (Fig. 12).
