肾恶性肿瘤血供特点及临床意义

Characteristics and significance of the blood supply of renal malignancies

目的分析肾恶性肿瘤的动脉血供特点,以指导临床治疗。方法对141例肾恶性肿瘤患者常规行腹主动脉造影及选择性可疑供血动脉造影,分析其供血动脉与肿瘤的部位、大小及介入治疗的关系。结果141例患者中发现90例由单一肾动脉供血,51例由肾动脉和肾外营养动脉同时供血,共发现肾外供血动脉81支。肾外供血动脉的形成与肾脏肿瘤突破肾包膜、肿瘤发生的部位及肾动脉闭塞有关。结论明确肾恶性肿瘤的动脉血供特点对于指导临床治疗具有非常重要的意义。

Objective To study the characteristics of the blood supply of renal malignancies and the significance for interventional therapy. Methods Routine abdominal aortography and selective questionable feeding arteriography were performed in 141 patients with renal malignancies. The characteristics of arterial blood supply of renal malignancies were analyzed. Results Of 141 patients, renal malignancies of 90 patients were supplied only by renal arteries. Renal and extrarenal arterial blood supply of renal malignancies were found in 51 patients and there were 81 extrarenal arterial branches. The emerge of extrarenal arterial blood supply of renal malignancies were correlated with the breakthrough of renal capsule, the position of tumor and occlusion of renal artery. Conclusion It is important to determine the characteristics of blood supply of renal malignancies for its interventional therapy.
