BACKGROUND
Reaching parenchymal segments of the lateral lenticulostriate artery (LSA) perforators, which represent the medial resection limit in insular gliomas (IG), remains a challenge. The currently described methods are indirect and sometimes, imprecise.
METHODS
We report an antegrade direct skeletonization technique to identify these tiny arteries at the medial end of IGs with an illustrative case of grade 2 astrocytoma. The patient recovered uneventfully following a near total tumor resection without any postoperative radiological ischemia in the LSA territory.
CONCLUSIONS
Our microsurgical technique of antegrade LSA skeletonization may be useful in insular gliomas with a sharp medial border.
背景
到达外侧豆纹动脉（LSA）穿支的实质段是一项挑战，该穿支代表岛叶胶质瘤（IG）的内侧切除界限。目前描述的方法是间接的，有时并不精确。
方法
我们报告一种顺行直接骨骼化技术，用于在IG内侧端识别这些微小动脉，并以一例2级星形细胞瘤为例进行说明。患者在近乎全肿瘤切除后恢复顺利，LSA区域无任何术后放射性缺血。
结论
我们的LSA顺行骨骼化显微手术技术可能对内侧边界清晰的岛叶胶质瘤有用。
