Thoracic endovascular aortic repair for ruptured descending thoracic aortic aneurysm.

BACKGROUND

We evaluated clinical outcomes of thoracic endovascular aortic repair (TEVAR) for ruptured descending thoracic aortic aneurysm (rDTAA).

METHODS

Twenty-three patients with rDTAA (mean age, 76.8 ± 8.8 years) underwent TEVAR at our center between January 2008 and April 2013.

RESULTS

In twenty-three patients, five patients (21.7%) were in shock before surgery. Technical success was achieved in 21 patients. After TEVAR, retrograde Type A aortic dissection occurred in one patient, Type I endoleak in one patient, and Type II endoleak in three patients. The 30-day mortality rate was 4.3% (n = 1), and there were five in-hospital deaths (21.7%). Six patients (26.1%) developed cerebral complications and two patients suffered from paraplegia. In the late phase, four patients died because of the following aortic events: re-rupture in one patient, rupture of another untreated aneurysm in two patients, and esophageal perforation in one patient.

CONCLUSIONS

TEVAR is associated with relatively low early morbidity and mortality and can be performed in older and high-risk patients. However, because aortic events during follow-up after TEVAR are not rare, we recommend close follow-up and application of early and aggressive reintervention.
