肾上腺转移癌非常见供血动脉DSA初步研究

Preliminary Digital Subtraction Angiography Discussion to the Unusual Feeding Artery to Metastatic Carcinoma of Adrenal Gland

目的探讨肾上腺转移癌非常见供血动脉情况,为介入栓塞治疗提供参考。方法对拟行动脉插管灌注及栓塞治疗的18例肾上腺转移癌患者,在术中DSA造影时观察肿瘤的供血动脉来源情况,统计和分析非常见供血动脉所占百分比及其插管成功率。结果 18例患者的肾上腺转移癌共有31支供血动脉,其中非常见供血动脉10支,占总供血动脉的32.3%,且40%来源于肝动脉(4/10)。10支非常见供血动脉插管成功率为90%(9/10)。结论肾上腺转移癌非常见供血动脉来源丰富,DSA术中尽量采用程序性造影,避免动脉插管灌注及栓塞治疗时的疏漏。

Objective To investigate the unusual feeding artery to metastatic carcinoma of adrenal gland,and offer help to treatment of interventional embolization. Methods Eighteen patients with metastatic carcinoma of adrenal gland were planned to treat with interventional catheterization perfusion and embolism therapy. During intraoperative DSA imaging to observe the source of tumor feeding artery,calculation and analysis of the percentage of feeding artery and the success rate of arterial cannula were taken into account. Results There were 31 feeding arteries in 18 cases of adrenal metastasis,of which 10 were unusual feeding arteries,which accounted for 32. 3% in the total feeding arteries and 40% of these sourced in hepatic artery. The success rate of arterial cannula was 90% in 10 unusual feeding arteries（ 9 /10）. Conclusion The source of unusual feeding artery was abundant. Use procedural imaging to the greatest extent during operation of digital subtraction angiography to avoid omissions of artery cannula infusion and embolization.
