How long will surgery take for an aneurysm repair?

How long would surgery be for an aortic aneurysm repair? It depends on the complexity and the modality employed. So a thoracic aneurysm repair involving just the thoracic aorta, if you're using an endovascular stent graft, can take half an hour from the time of incision till finishing. If that's done open, involves an incision through the chest and often involves placing the patient on bypass. That can take several hours, three or four hours. The endovascular treatment of pararenal aneurysms or thoracobdomal aneurysms, again, tends to vary between three and seven hours in very difficult cases. An open infrarenal repair would normally take somewhere in the region of three hours, but again, depending on the complexity and an endovascular stent graph for an infrared lanyardism can be as quick as half an hour again in some extremely efficient and accomplished centres but if there are technical challenges it can take an hour and a half. Anything longer than that means that probably there's been some unexpected events or difficulties. So it can vary really on how simple the case is and what modality that we're using to fix it.
