Factors Associated with Postoperative Neurologic Improvement after Endovascular Treatment for Spinal Vascular Lesions: Japanese Registry of Neuroendovascular Therapy 2, 3, and 4

In Japan, treatment of spinal vascular lesions was administered with relative safety, and better outcomes were achieved at high-volume centers. In SDAVFs, total shunt obliteration and avoidance of complications are critical factors for achieving neurologic recovery. In SPAVFs, selecting an appropriate treatment strategy based on the vascular architecture is essential to minimize complications for achieving favorable postoperative outcomes. In SIAVMs, disease management should take precedence over radical intervention. Furthermore, the disruption of neurologic recovery by hemorrhagic onset in both SPAVFs and SIAVMs highlights the importance of early diagnosis and timely intervention.
