Significance of Procedural Arteriography in Interventional Embolization of Adrenal Metastasis Carcinoma / 中国医学影像学杂志

ABSTRACT

Purpose To investigate the significance of procedural arteriography in interventional embolization of adrenal metastasis, due to the fact that it is usually difficult to seek feeding arteries in the treatment of adrenal metastasis using interventional embolization. Materials and Methods Eighteen patients with adrenal metastasis were treated with procedural arteriography and interventional embolization therapy, the source and number of feeding arteries was retrospectively analyzed. Results The total success rate of procedural arteriography was 95.5%. The abnormal feeding arteries which were discovered by procedural arteriography accounted for 29.0%. The number of feeding arteries was two, which were mainly derived from inferior suprarenal artery and superior suprarenal arteries. Conclusion The source of feeding arteries of adrenal metastasis is abundant and the variability is obvious, thus procedural arteriography should be used to the greatest extent during operation of digital subtraction angiography to avoid omission of feeding arteries.
