Quizplus · Accepted Answer

If a sequestration is suspected, an arteriogram can be diagnostic and helpful to define the arterial anatomy, which is crucial to successful resection. The systemic arterial supply may arise directly from the aorta, at times even through the diaphragm from the intra-abdominal aorta. Injury or inadvertent division of this vessel without proper control may result in a hemorrhagic catastrophe.
