This report describes 3 patients with previously untreated hepatic tumors who underwent embolization for the treatment of extravasation from extrahepatic arteries. Although development of extrahepatic collateral blood supply is well known, its importance in the presentation of rupture of liver tumors may be underrecognized. Findings that suggest bleeding from extrahepatic arteries include a discrepancy in the pattern of extravasation on computed tomography vs hepatic angiography and a lack of stabilization of vital signs after embolization of hepatic arteries. To achieve successful hemostasis in embolization, the potential involvement of such extrahepatic arteries should be accurately recognized, suggestive imaging findings considered, and the occult vessels selected and embolized.
本报告描述了 3 例先前未经治疗的肝肿瘤患者，他们因肝外动脉外渗而行栓塞治疗。尽管肝外侧支循环血供的发展是众所周知的，但它在肝肿瘤破裂表现中的重要性可能被低估。提示肝外动脉出血的发现包括 CT 与肝动脉造影在漏出模式上的差异，以及肝动脉栓塞后生命体征的不稳定。为了在栓塞治疗中实现成功止血，应准确识别这种肝外动脉的潜在参与，考虑到提示性的影像学发现，并选择和栓塞隐匿的血管。
