cial detachable embolization coils are available and there is no evidence of superiority among the coils. The main principle applicable regardless of the embolization coil device is that it is imperative for the aneurysm to be packed as tightly as possible in order to facilitate thrombosis and occlusion of the aneurysm. In our case, there was successful exclusion of the aneurysmal sac with no significant flow noted at the efferent branches. Placement of a stent-graft was considered for complete occlusion of the feeding vessel. This was however not performed given the satisfactory angiographic result, and placement of a stent at this point would have been excessive. Additional stent graft placement at the thoracic aorta would also increase the risk of spinal ischaemia. It is also of the authors’ opinion that a stent-graft would have negated future possibilities of endovascular therapy in this patient. It may be more prudent to follow-up the patient and to place a stent-graft in the future if the need arises. In summary, we report a case of a large mediastinal BAA with short vascular neck that was successfully treated with coil embolization. Endovascular therapy is being increasingly used as it is effective, less invasive and is associated with lesser morbidity and shorter hospital stays as compared to surgical treatment.
