显微测量Graves病腺体血管口径提高介入治疗的疗效

目的 显微测量Ｇｒａｖｅｓ病甲状腺体内的血管平均口径，选择合适栓塞微粒的大小，以期达到更完整的栓塞治疗效果。方法 将栓塞治疗后的甲状腺作多层次切片，石蜡切片，ＨＥ染色，应用显微长度测量计（Ｏｌｙｍｐｕｓ）测量各不同部位的血管内径。结果 腺体部接近上下诈的网状血管内径平均为０．１２￣０．２５ｍｍ，最小动脉内径平均为０．０４￣０．１１ｍｍ。甲状腺峡部的血管，内径平均为０．１３￣０．１５ｍｍ。甲状腺上下

Measuring diameters of thyroid arteries in Graves disease by improving theurapentic effect of intervention radiology

Objective In order to select appropriate size of embolizing granules and to achieve complete embolization and good therapeutic effect, the diameters of thyroid arteries in Graves disease was measured. Methods Multiple slides of embolized thyroid tissues from superior pole, body and inferior pole of resected thyroid glands were made. After being embeded and stained, diameters of arteries in various parts of thyroid glands were measured with microscope calipers (Olympus). Results Average diameter capillary network of the thyroid body gland adjacent to superior, infreior artery was 0. 12-0. 25 mm, and the smallest one was 0. 04-0. 11 mm. The diameter of isthmus was 0. 130. 15 mm. The average diameter of superior and inferior artery was 2- 5. 5 mm and 3. 0- 3. 75 mm measured by using interventional angiography Conclusion According to the diameters of arteries which were measured, complete embolization and good therapeutic effect can be achieved.
