The venous drainage of the vertebral and paravertebral regions is important for a better understanding of hematogenous disease spread. Moreover, the spine surgeon must be well acquainted with this anatomy in order to minimize intra and postoperative complications. Herein, a comprehensive review of the vertebral venous plexus (Batson's plexus) was performed with a concentration upon the clinical and surgical correlations of this venous network.

A recent systematic review and meta-analysis found there was a lack of consensus regarding risk factors for cerebral vasospasm in aneurysmal subarachnoid hemorrhage (aSAH). ⋯ In the first nationwide analysis of cerebral vasospasm, risk factors included younger age, female sex, smoking history, hemodynamic compromise, and clinical severity of aSAH. Recently proposed biomarkers, including leukocytosis and hypokalemia, were supported by our findings. This study may assist risk-stratification and earlier detection of vasospasm.

The principles of endovascular treatment of bilateral cavernous sinus dural arteriovenous fistula (CS-dAVF) are not well established due to the complexity in the number of fistula tracts and their behavior which seems to be more aggressive. We aimed to determine an efficient technique for endovascular treatment of bilateral CS-dAVF and the associated factors to achieve good clinical and angiographic outcomes. ⋯ Dangerous venous drainage tends to increase in bilateral CS-dAVF. Retrograde ipsilateral inferior petrosal sinus catheterization using coil embolization and sequencing the embolization are the major concerns for treatment.

Meningiomas are mostly benign intradural tumours. Concerning the spine, some of them can extend outside the canal or even develop extradurally but their primary attach is often located in the vertebral canal. Here we present the case of an exceptional purely intra-foraminal meningioma mimicking neurogenic tumour, involving the vertebral artery and presenting with cervico-brachial neuralgia and slight motor deficit.

This article analyses some parameters and characteristics of CT images on gastric cancer patients, and discusses the application of CT images in the diagnosis of gastric cancer endocrine nerves and the impact of nursing intervention on the quality and mental state of CT imaging images of gastric cancer patients. First, all patients were scanned with CT images, and the CT values of the normal stomach wall and all lesions at different single energy levels were recorded separately. ⋯ The results show that the energy spectrum curve of CT images and the improved BP network model are helpful for the initial diagnosis and identification of gastric cancer. At the same time, nursing intervention has a good influence on the clinical examination, image diagnosis and psychological state of patients with gastric cancer, and it is easy for patients to undergo image diagnosis and examination according to correct operating procedures.
