The use of intraluminal prosthesis in the surgical management of aortic dissection

The treatment of acute aortic dissection requires expeditions and reproducible operations aimed at avoiding rupture of the dissection or its antegrade or retrograde progression. In 12 type A and 11 type B dissections the aorta was repaired using an intraluminal prosthesis to reduce the risk of hemorrhage and its related complications. Overall mortality rates were 33% in type A and 36% in type B patients, similar to that observed in patients operated with other techniques, but the incidence of intraoperative bleeding was possibly reduced and the cross-clamping time was significantly shorter. This method of repair is a sound alternative to conventional anastomotic suturing, particularly in clinically compromised patients and in the hands of surgeons on call, who may lack the experience of dealing with a particularly fragile aortic wall.
