Elephant Trunk Technique with a Handmade Skirted Tube Graft: How Do We Prepare It?

The surgical treatment of diffuse thoracic aortic pathologies remains a challenge in aortic surgery for surgeons. Traditionally, these aortic diseases are treated with a 2-step approach known as the "elephant trunk procedure." This technique gives us an opportunity for the construction of the distal anastomosis during the initial operation. However, this staged approach is associated with a substantial overall mortality and morbidity. In order to improve the outcomes, few single-stage repair methods have been tried. Most of them are performed through a clamshell incision, and for this reason, it is potentially associated with a high incidence of pulmonary complications. Repair techniques of diffuse thoracic aortic pathologies have changed substantially over the last decade; these techniques appear to have a significant lower operative risk for patients. "Frozen elephant trunk" (FET) technique was developed for combined lesions of the thoracic aorta as a single-stage procedure which is a combination of endovascular treatment and conventional surgery. However, experiences are limited in the field of FET and endovascular techniques that is why traditional 2-staged approach still remains as a first choice in our clinic like many centers. In eligible patients, we use a handmade skirted tube graft for conventional technique in 2-staged repair for diffuse thoracic aortic aneurysm. In this report, we aim to explain the possible advantages of this graft and how we do it.
