In 10 patients with an occluded aorta, angiography performed with the catheter in the abdominal aorta failed to opacify the reconstituted distal extremity arteries. Repeat injection into the thoracic aorta resulted in adequate opacification of the leg vessels through internal mammary-inferior epigastric artery collaterals. Moving the catheter from the abdominal aorta to the ascending aorta or selectively into the internal mammary artery is suggested when standard abdominal aortic injection fails to demonstrate runoff vessels.
在10例主动脉闭塞患者中，将导管置于腹主动脉进行血管造影时，未能使远端重建的肢体动脉显影。再次向胸主动脉注射造影剂后，通过乳内动脉-腹壁下动脉侧支循环使腿部血管获得了充分显影。当标准的腹主动脉注射未能显示流出道血管时，建议将导管从腹主动脉移至升主动脉或选择性地插入乳内动脉。
