Abstract

Objectives: The aim of this study was to evaluate the mid-term outcomes of thoracic endovascular aortic repair (TEVAR) of complicated
type B aortic dissection.
Patients and methods: This retrospective study included a total of 29 consecutive patients (27 males, 2 females; mean age 61.1±11.8 years;
range, 34 to 80 years) who underwent TEVAR due to complicated type B aortic dissection at our center between March 2015 and December
2018. All pre-, intra-, and postoperative data were collected. Surgical and discharge notes were reviewed.
Results: Of the patients, 27 had hypertension and seven had coronary artery disease. The mean maximum aortic diameter was 50.5±7.7 mm.
Suspicion of impending rupture was the most (n=13) associated complication with type B aortic dissection. Six patients (20.7%) had rupture
and 10 patients (34.5%) had uncontrolled hypertension. The procedure was performed under elective conditions in 18 patients (62.1%) and
under emergency setting in 11 patients (37.9%). Early mortality was developed in one patient (3.4%) due to low cardiac output syndrome. The
mean follow-up was 25±11 months. Late mortality occurred in two patients (6.9%) due to lung cancer and sepsis. The overall survival rate was
86.1±9.8% and freedom from aortic re-intervention was 88.8±7.5% at 50 months.
Conclusion: Our study results show that TEVAR is a safe procedure associated with good postoperative outcomes, and outstanding mid-term
results in complicated type B aortic dissection
