Abstract
CSF-venous fistulas (CVFs) are an important cause of spontaneous intracranial hypotension and challenging to diagnose. Lateral decubitus positioning during myelography and a technique called "resisted inspiration" has shown to improve CVF detection. However, the impact of intrathecal pressurization to improve visualization of CVF has mostly been speculated on. In this brief report, we demonstrate how a CVF became progressively more visible only after stepwise intrathecal pressurization: An indication of the importance of pressurization for CVF detection.
摘要
脑脊液-静脉瘘（CVF）是自发性颅内低压的一个重要原因，且诊断具有挑战性。脊髓造影时的侧卧位以及一种称为“用力吸气”的技术已被证明可提高CVF的检出率。然而，鞘内加压对改善CVF可视化的影响大多只是推测。在本简短报告中，我们展示了只有在逐步鞘内加压后，CVF才逐渐变得更加明显：这表明加压对CVF检测的重要性。
