儿童肾血管造影术和栓塞术的临床评价

Clinical evaluation of renal angiography and embolization in children

目的 分析评价肾血管造影术在儿童肾母细胞瘤及肾血管性病变的应用。方法 分析了２９ 例患儿。对１６ 例肾母细胞瘤的患儿行术前肾动脉造影及化疗栓塞术。１２ 例不明原因的高血压行肾血管造影及血浆肾素水平的测定。１ 例为血尿患儿。结果 栓塞术后肾母细胞瘤肿瘤血管减少，受肿瘤影响的病肾缩小，肿瘤周围组织与正常组织分界清晰，减少肿瘤细胞进入血流及向远处转移。肾血管性高血压得到了明确诊断，肾素水平的提高有助于诊断不明原因的高血压。结论 肾血管造影术和栓塞术是完全可靠的。

Objective To evaluate the role of renal angiography in Wilms tumor and Renal vascular lesions in children.Methods We analysed 29 cases, 15 males, 14 females, mean age of 7 years old. Preoperative renal arterial chemotherapy and embolization for Wilms tumor were carried out for 16 cases. Angiography and selective venous sampling for renin in renovascular hypertension were performed for 12 cases, with one of hematuria. Results The Wilms tumor showed reduction in vascularization, decrease the size of mass of kidney to separate from the surrounding tissue, to avoid the operative spillage of malignant cells into the blood stream and the metastasis. Renovascular hypertension was achieved with definite diagnosis. Renal vein renin elevation help to predict response of hypertension for the diagnosis. Conclusions Angiography is a valuable diagnostive tool in the study of renal abnomalities. This procedure is safe, reliable and popular clinically.
