肿瘤内血管的立体构筑及毛细血管超微结构特点是研究肿瘤血液供应的形态学基础,对于正确的阐明肿瘤的生长、浸润、转移、坏死及其治疗具有重要指导意义。本文报道肺鳞状细胞癌、腺癌及未分化癌组织内血管立体构筑和毛细血管超微结构的特点。应用ABS 进行肺癌内血管铸型,可以观察肺癌内的中小动脉、微动脉、毛细血管前小动脉及毛细血管的立体构筑。光镜观察结果,各
The three-dimensional structure of the blood vessels in the tumor and the ultrastructural characteristics of the capillaries are the morphological basis for studying the blood supply of the tumor, and have important guiding significance for the correct elucidation of tumor growth, infiltration, metastasis, necrosis and its treatment. In this paper, the vascular three-dimensional structure and capillary ultrastructure of lung squamous cell carcinoma, adenocarcinoma and undifferentiated carcinoma were reported. The use of ABS for intracoronary vascular casting can be used to observe the three-dimensional construction of small and medium arteries, arterioles, precapillary arterioles, and capillaries in lung cancer.
