Background:
We present an analysis that compares aortic morphological and clinical outcomes of 36 patients, all treated with endovascular uncovered stents implantation preceded or not by stent-graft implantation, or surgical treatment in the context of complex treatment of type A or type B aortic dissection.
Methods:
Between 2014 and 05/2018 our team treated 36 patients with acute aortic dissection and end-organ ischemia due to true lumen compression. All clinical and periprocedural data were obtained prospectively, followed by a retrospective analysis. The case series aim is to show induction of aortic remodeling by depressurization of the false lumen and increasing the size of the true lumen by non-covered stents implantation in the aorta and its affected side branches. Secondary endpoints were survival, branch patency, true lumen and false lumen size evolution.
Results:
Results from the diameter of both lumens measured by computed tomography angiography (CTA) before and at least 1 year after the treatment showed statistically significant differences, patent stents, as well as symptomatic improvement in all patients. Both aorta-related and general mortality in this complex group of patients was 0%.
Conclusions:
The concept of redirection of flow in aortic dissection with non-covered stents was safe, led to positive aorta remodeling and resulted in excellent survival rate.
