Zusammenfassung: | Endovascular treatments for thoracic aortic diseases have been adopted rapidly, and long-term studies are relevant for durability evaluation.
To evaluate the long-term results of a prospective observational study of endovascular treatment in patients with thoracic aortic diseases who underwent percutaneous implantation of self-expandable endoprostheses.
Procedural success was defined as the absence of endoleak into the aneurysm or dissection-induced false lumen, no migration, and no conversion to open surgery. Intraoperative, postoperative, and late postoperative outcomes were evaluated in terms of complications, mortality, and evolution of the endoprosthesis over a follow-up of up to 179 months (median: 46 months).
A total of 150 endoprostheses were implanted in 112 patients. Primary success was observed in 100 (82.14%) patients. Immediate mortality occurred in 7 patients (6.25%). Late mortality occurred in 31 patients (27.68%), 10 (8.93%) of whom died from cardiovascular causes, 12 (10.71%) from non-cardiovascular causes, and 2 (1.78%) from natural causes, while 7 (6.25%) had no diagnosis for cause of death. Types I, II, and IV endoleaks occurred during hospitalization in 4 (3.57%), 5 (4.46%), and 3 (2.68%) patients, respectively. Late types I and IV endoleaks occurred in 5 (4.46%) and 3 (2.68%) patients respectively. Twenty-two patients (19.64%) had clinical complications in the immediate postoperative period. Actuarial survival free from death from cardiovascular causes was 79.3% (95% confidence interval, 67.0-91.7%) at 132 months.
The low levels of intraoperative and postoperative complications demonstrate that endovascular treatment is safe and effective. The high rate of late survival for these critically ill patients indicates that the endovascular technique is beneficial for treatment of thoracic aortic diseases in terms of long-term outcomes. |
