This article provides an illustrated guide to the elephant trunk procedure for aortic aneurysm repair, detailing the surgical technique and normal postoperative CT imaging appearance.
Provides a reference for CT interpretation after elephant trunk repair; leaves open prospective validation of complication rates.
OBJECTIVE: The purpose of this article is to provide a comprehensive overview of a relatively new surgical aortic procedure, the elephant trunk technique. In conjunction with information from the literature, a series of illustrations provide a detailed description of the surgical procedure and postoperative appearance with CT correlation. CONCLUSION: This article explains the rationale behind a staged thoracic aortic surgery, describes and illustrates the surgical technique used to perform the elephant trunk procedure and the normal postoperative imaging appearance, and discusses potential complications specific to the elephant trunk procedure.
