目的研究甲状腺假被膜的解剖学形态特点,探讨其临床意义。方法在95例单侧甲状腺叶切除术中,观察甲状腺假被膜的解剖学形态,甲状腺假被膜与真被膜、甲状腺血管、甲状旁腺和喉返神经的关系。结果在甲状腺下静脉、中静脉和上血管附着于腺体的部位,甲状腺假被膜呈“系膜”样结构附着在腺体上,切除腺叶后观察“系膜”呈“C”型的延续平面,甲状腺下静脉、中静脉和上血管分别自系膜缘穿出,喉返神经、甲状腺下动脉、甲状旁腺位于“系膜”的“C”型圈内。结论对甲状腺假被膜的解剖新认识,有助于术者安全的完成甲状腺手术,特别是被膜解剖技术的应用。
Objective To study the anatomical characteristics of thyroid pseudomembrane and to explore its clinical significance. Methods In 95 cases of unilateral thyroid lobectomy, the anatomy of thyroid pseudofasure, the relationship between thyroid pseudomembranous and true capsule, thyroid blood vessels, parathyroid and recurrent laryngeal nerve were observed. Results In the parts of the thyroid gland, the middle veins and the upper blood vessels attached to the gland, the thyroid pseudofilm was attached to the gland in the “mesenteric” -like structure. After removal of the glandular lobes, “mesangial” was observed as “ C ”shape of the continuum, the thyroid vein, the middle vein and the blood vessels were from the mesangial margin piercing, recurrent laryngeal nerve, thyroid artery, parathyroid located in the“ mesangial ”“ C ”type Circle. Conclusion The new understanding of thyroid pseudomembranous anatomy is helpful for the surgeon to safely perform the thyroid surgery, especially the application of the anatomic technique of the capsule.
