A Right Intercosto-Bronchial Artery Derived from the Thyrocervical Trunk: An Unusual Cause of Type II Endoleak Post Thoracic Aortic Stenting

The aetiology, incidence and management of type II endoleaks in standard infrarenal endovascular aortic aneurysm repair is well described. Far less data is available for thoracic stent grafting. We present a rare and interesting case of a type II endoleak post thoracic aortic stenting and highlight the aberrant anatomy that can cause this phenomenon in such cases.
