Abstract

Background: This study presents a single center's experience and analyzes clinical outcomes following elective open surgical descending aortic replacement.

Methods: Between January 2000 and August 2019, 96 patients with mean age 64 years (range, 49.5-71 years) (62.5% (=60) male) underwent elective descending aortic replacement due to aneurysm (=60) or chronic dissection (=36). Marfan syndrome was present in 12 patients (12.5%).

Results: In-hospital mortality rate was 3.1% (= 3. 2 in the aneurysm group, 1 in the dissection group). New-onset renal insufficiency postoperatively with (creatinine ≥ 2.5 mg/dl) manifested in 10 patients (10.8%). One patient (1%) suffered from stroke, and paraplegia developed in 1 pts (1%). The median follow-up time was 7 years (IQR: 2.5-13 years). The 5- and 10-year survival rates were 70.8% and 50.7% respectively. We did not observe any early or late prosthetic graft infection. The Cox proportional hazards regression analysis identified age (HR: 1.044, 95% CI: 1.009-1.080, -value: 0.014), diabetes (HR: 2.544, 95% CI: 1.009-6.413, -value: 0.048), and chronic obstructive pulmonary disease (COPD) (HR: 2.259, 95% CI: 1.044-4.890, -value: 0.039) as risk factors for late mortality.

Conclusions: This study showed that the elective open surgical replacement of the descending aorta can be achieved with excellent outcomes in terms of perioperative mortality and morbidity. Prosthetic graft is not a problem with open surgical descending aortic replacement, even in the long term.
