Outcomes after treatment of acute aortic occlusion.
BACKGROUND
Acute aortic occlusion (AAO) is a rare disease with high morbidity and mortality. The aim of this study was to describe the results of surgical treatment of acute aortic occlusion and risk factors for mortality.


METHODS
Retrospective review of the clinical history of 29 patients diagnosed and operated on for AAO during 28 years. The following variables were analysed: age, sex, tabaco use, diabetes, chronic renal insufficiency, chronic heart failure, atrial fibrillation, arterial hypertension, symptoms, diagnosis and treatment, 30-day mortality and long-term survival. A univariant analysis was performed of variables related to mortality.


RESULTS
Twenty-nine patients were included (18 male) with a mean age of 66,2 years. The aetiology was: embolism (EM) in 11 cases and Thrombosis (TR) in 18 cases. The surgical procedures performed included bilateral transfemoral thrombectomy (14 cases), aorto-bifemoral by-pass (8 cases), axilo uni/bifemoral by-pass (5 cases) and aortoiliac and renal tromboendarterectomy (2 cases). Morbidity included: renal failure (14 cases), mesenteric ischemia (4 cases), cardiac complications (7 cases), respiratory complications (5 cases) and loss of extremity (2 cases). The in-hospital mortality was 21% (EM 0%, TR 21%). The estimated survival at 1.3 and 5 years was 60, 50 and 44% respectively. Age (p=0.032), arterial hypertension (p=0.039) and aetiology of the AAO (p=0.039) were related to mortality.


CONCLUSIONS
Acute aortic occlusion is a medical emergency with high mortality rates. Acute renal failure is the most common postoperative complication.
