(一)甲状旁隙机能亢进患者经插管对比剂染色治疗的长期随访[Geelhoed GW:Surgery 1983,94:849(英文)]甲状旁腺及其腺瘤的血管解剖学为插管切除疗法提供了一个理想的目标.甲状旁腺甚至甲状旁腺腺瘤仅有一根动脉供应,并无侧枝血管.因此,用明胶海绵或硅胶栓塞其营养血管使甲状旁腺梗死的最初目的是治疗甲状旁腺腺瘤,后来发展成为用放射线造影剂使甲状旁腺腺瘤染色的疗法.将导管选择性地插入腺瘤动脉内,使动脉阻塞,然后以较高压力注射水溶性造影剂,使高渗性造影剂渗入组织间隙,对腺实质造成高渗性、化学毒性和缺血性损害,使其功能丧失.通常需要注射二次或多次造影剂,第一次在10秒钟内
(i) Long-term follow-up of intubated contrast agent staining for hyperparathyroidism [Geelhoed GW: Surgery 1983, 94: 849 (English)] Vascular Anatomy of Parathyroid and Adenoma for Intubation Resection An ideal target. The parathyroid gland and even the parathyroid adenoma are supplied by only one artery and no collateral vessels. Therefore, the primary purpose of infiltrating parathyroid glands with a gelatin sponge or silica gel is to treat the parathyroid gland. Adenoma, which later developed into a treatment for staining parathyroid adenomas with a radiocontrast agent. The catheter is selectively inserted into the adenoma artery to block the artery, and then the water-soluble contrast agent is injected at a higher pressure to hypertonicity. The contrast agent penetrates into the interstitial space and causes hyperosmolar, chemical and ischemic damage to the glandular parenchyma, causing loss of function. Usually two or more contrast media injections are required, within the first 10 seconds.
