Geniculocalcarine fibers are thought to be exclusively ipsilateral. However, recent findings challenged this belief, revealing bilateral recruiting responses in occipitotemporoparietal regions upon unilateral stimulation of the lateral geniculate nucleus (LGN) in humans. This raised the intriguing possibility of bilateral projections to primary visual areas (V1). This study sought to explore the hypothetical decussation of the geniculocalcarine tract. ⋯ This study suggests a partial decussation of the fibers between LGN and V1, likely constituting the geniculocalcarine tract.

Puncture-site complications in interventional radiology sometimes cause severe conditions. Vascular closure devices play an important role in preventing puncture-site complications. Vascular closure devices are divided into 2 types, the directly suturing or clipping type (active approximators) and adherent sealant types (passive approximators). However, which types of vascular closure device are the safest and most effective for achieving hemostasis remains unclear. We analyzed the efficacy of each type of vascular closure device and risk factors for puncture-site complications. ⋯ Passive approximator use in patients with shallow femoral artery depth increases puncture-site complications in neuroendovascular treatment.

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.

Inflammatory response is closely associated with secondary brain injury and pneumonia in intracerebral hemorrhage (ICH). In this study, we aimed to investigate the value of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic immunoinflammatory index (SII) in the development of pneumonia in ICH patients 30 days after surgery. ⋯ In the course of ICH, NLR, PLR, and SII increased and then decreased and peaked at 48 hours postoperatively. The SII3 was the best predictor of the occurrence of pneumonia postoperatively in ICH patients.

We report on an elderly woman with sciatica due to disc herniation, experiencing complete pain resolution following surgery. Four weeks later, she developed refractory, excruciating pain with foot palsy, prompting a lumbar magnetic resonance imaging that revealed no recurrent disc herniation. Upon exploration, intermittent nerve entrapment through the dural tear and pseudomeningocele was identified. ⋯ In contrast to recurrent disc herniation, sciatica resulting from nerve entrapment by a pseudomeningocele is exceedingly rare. Its differential diagnosis is crucial in cases with seemingly unspectacular magnetic resonance imaging findings, as paralysis can occur in symptomatic patients. The radiological presence of a postoperative pseudomeningocele could be overlooked, and the cause of sciatica might become apparent solely during surgical exploration.
