肾动脉栓塞术(附8例报告和文献复习)

本文报道了为肾肿瘤的诊断和治疗所进行的8例肾动脉栓塞,其中1例为巨大结核性脓肾。先进行选择性肾动脉造影,确定诊断后,再进行肾动脉栓塞。全部栓塞剂均为医用明胶海绵。栓塞后,肾脏周围与健康组织有水肿,易于分离,肿瘤缩小,表面血管萎陷,便于手术切除肿瘤,出血和输血均减少,提高了手术切除率。对于晚期肾癌或有远处转移的病人,手术不能切除时,经过肾动脉栓塞之后,体内免疫功能增强,转移灶可以缩小甚至消失,起到延长病人生命的作用。

Renal arterial embolization-with a report of 8 cases and literature review

The role of renal arterial embolization in the diagnosis and treatment of renal tumors was discussed and 8 cases were reported. In all cases,gelatin sponge was used for embolization,and renal arteriography was taken prior to renal arterial embolization in order to assure the diagnosis. After embolization, edema occurred in the perirenal tissue, enabling dissection more easily. Besides, the tumor mass shrank in volume, with superficial blood vessels collapsed, making resection of the tumor more convenient,bleeding decreased,and thus saving the amount of blood transfusion. In one word, the operability of the disease increased after renal arterial embolization. In case of advanced renal carcinoma or patients with distant metastasis where resection of the tumor is impossible,renal arterial embolization may enhance the immunological function of the patient, making the metastasis reduced in size, even disappeared, and thus extending the patients' life.
