Prophylactic stage 1 elephant trunk for moderately dilated descending aorta in patients with predominantly proximal disease

摘要

Objective: Staged elephant trunk (ET) repair is a commonly performed procedure for extensive aortic disease. A significant proportion of patients with predominantly proximal aortic pathology often have in addition a moderately dilated descending aorta (< 5 cm) that can progress over time. Objectives were to characterize patients, determine completion rate after prophylactic stage 1 ET, and assess outcomes.
