Endovascular Repair for the Descending Thoracic Aorta

"Thoracic endovascular aortic repair with Endoluminal stent-graft placement (Valiant™ endoluminal stent-graft systems (Medtronic Inc., Santa Rosa, CA, USA) will be performed as follows:~The diameter of the stent graft will be calculated from the largest diameter of the proximal/distal neck with an oversizing factor of 10-20%. The procedures will be done with local or general anaesthesia in case of unstable pre-operative hemodynamic conditions.~After the procedure will be completed, a digital subtraction angiography and echocardiography with color-flow mapping were performed to verify the correct positioning of the stent and to detect any primary endoleak."
