The benefits of internal thoracic artery catheterization in patients with chronic abdominal aortic occlusion.
Occlusion of the abdominal aorta may be caused by an embolic lesion, but more commonly by thrombotic disease at the aortoiliac area, progressing retrograde. However, the visualization of the distal run-off via internal thoracic-epigastric inferior artery collateral channel may be a very important diagnostic tool, especially in countries with poor technical equipment. This study was designed to show the benefit of the selective internal thoracic angiography in cases with complete aortic occlusion. We present 30 patients with chronic aortic abdominal occlusion who were submitted to the transaxillary aortography and selective ITA angiography with purpose of distal run off evaluation. Angiographic evaluation was performed by two independent radiologists according to previously defined classification. Good angiographic score via internal thoracic angiography by first observer was achieved in 19 (63.3%) patients and in 18 (60%) by a second observer. Transaxillary aortography showed inferior results: good angiographic score by the first observer in six (20%) patients and by the second observer in three (3%) patients. Low extremity run-off is better visualized during internal thoracic angiography than during transaxillary aortography.
