Malignant cerebral edema (MCE) is associated with both net water uptake (NWU) and infarct volume. We hypothesized that NWU weighted by the affected Alberta Stroke Program Early Computed Tomography Score (ASPECTS) regions could serve as a quantitative imaging biomarker of aggravated edema development in acute ischemic stroke with large vessel occlusion (LVO). The aim of this study was to evaluate the performance of weighted NWU (wNWU) to predict MCE in patients with mechanical thrombectomy (MT). ⋯ This study revealed that wNWU at admission can serve as a quantitative predictor of MCE in LVO with successful recanalization after MT and may contribute to the decision for early intervention.

The efficacy of medical treatments and the changes in radiologic imaging before and after treatment have consistently remained pivotal factors. This is particularly critical for surgical procedures, where precise evaluation of disparities pre and postsurgery or the accuracy of implantation is paramount. Based on three-dimensional morphological interests, we provide an automatic quantification evaluation method that delivers an evident base for assessing the outcomes of a widely employed surgical technique, cervical laminoplasty. ⋯ The quantification evaluation method can be utilized for any morphology changes before and after laminoplasty, as it does not lead to errors or variations from different inspection machines or human factors. The automatic method delivers an evident base for assessing the outcomes of a widely employed surgical technique.

The purpose of this report is to describe a case series of children undergoing selective dorsal rhizotomy (SDR) for the treatment of spastic cerebral palsy in Vietnam. Also described is an international cooperation model to facilitate the development of a new, multidisciplinary team for the evaluation and treatment of these children. ⋯ The ongoing international cooperation between Vietnamese and American physicians has helped improve the surgical treatment of spasticity in children with cerebral palsy in Hanoi, providing children with a surgical treatment option with successful outcomes.

Two main surgical techniques are available for corpus callosotomy (CC): conventional microscopic CC and endoscopic CC.1 Microscopic CC is more familiar to neurosurgeons and allows three-dimensional visualization, but it requires a larger craniotomy and has a narrower visual angle in the deep part. Endoscopic CC has only recently been introduced to epilepsy surgery, but it is gaining increasing interest among epilepsy surgeons. The endoscope provides two-dimensional visualization and requires a camera as an additional instrument inserted into the surgical corridor. ⋯ In some cases, this procedure can take a long time. On the other hand, a posterior approach requires less interhemispheric arachnoid dissection, or sometimes none at all, due to the anatomy of the falx cerebri. These reasons have driven the development of a posterior approach for an endoscopic-alone technique.3 Here, we present a 5-year-old girl with medically intractable epileptic spasms that were diagnosed as infantile epileptic spasms syndrome, who underwent endoscopic total CC via a posterior approach to control her seizures (Video 1).

This study aimed to identify risk factors for postoperative proximal junctional kyphosis (PJK) with vertebral fracture in adult spinal deformity (ASD) patients. We performed a survival analysis considering various factors, including osteoporosis. ⋯ PJK with vertebral fracture affected 25% of ASD patients, emphasizing the importance of osteoporosis evaluation. Existing vertebral fracture emerged as a significant independent risk factor, surpassing bone mineral density. This study provides valuable insights for spine surgeons, highlighting the need to provide osteoporosis treatment and emphasize potential postoperative complications during discussions with patients.
