神経膠腫摘出時の深部細動脈損傷による虚血合併症としての運動麻痺

抄録

Maximization of tumor resection and minimization of surgical morbidity during glioma surgery depends on two fundamental requirements, i.e., determination of the resection border and preservation of the involved arteries and veins. Techniques to preserve the involved vascular structures must consider deep-situated narrow arteries including the perforating arteries. This presentation will focus on the anterior choroidal arteries, subependymal arteries originating from the lateral posterior choroidal arteries, thalamotuberal arteries, and thalamogeniculate arteries. Damage to these arteries during glioma resection carries the risk of postoperative hemiparesis. Postoperative diffusion-weighted magnetic resonance imaging may demonstrate infarction at different parts of the descending motor pathway. Preservation of these arteries is one of the most important procedures to prevent adverse events caused by glioma resection. Detailed knowledge of the anatomy is essential to preserve these arteries.
