TAAA: Back table surgeon-modified stent-graft with internal branches

We report some cases performed with a stent-graft modified by the surgeon with internal branches for the treatment of TAAAs. In total, we have 34 cases performed with this technique and we developed and patented a low profile device to be used in almost all anatomical types of TAAAs. This device may be considered off-the-shelf graft. See also:

Marco Lourenco replied to your comment on presentation An off the shelf and low profile stentgraft for treatment of thoracoabdominal aneurysms.

»Dear Özgün, Thank you very much for your questions! I prepare the device at the same time, just before the surgery. I prefer the valiant thoracic device and the viabahn for the internal branches, than I've been use the viabahn or the begraft for the connection to the visceral branches. I did in the past some cases of fenestrated devices since 2004. After 2013, my first case with this technique, my preference is branched device even for juxtarenal aneurysm. Best regards Thanks again Marco«
Experimental investigation

An off the shelf and low profile stentgraft for treatment of thoracoabdominal aneurysms

I recently developed an off the shelf stentgraft for treatment of thoracoabdominal aortic aneurysms involving the visceral branches. With this off the shelf device, aneurysms can be treated with any anatomical configuration of the visceral vessels, such as only 1, 2, 3 or 4 branches. I began to have the idea of developing this device from a technique of internal branches that I developed for treatments of thoracoabdominal aneurysms. We performed almost 40 patients with this technique.
