Simple Retrieval Technique of the Elephant Trunk by Partial Aortic Clamping. The frozen elephant trunk technique for various thoracic aortic diseases is widely accepted to facilitate future downstream aortic surgery. However, in some cases, the descending aorta is unsuitable for cross-clamping due to progressive aneurysmal changes or dense adhesions to surrounding structures, and frozen elephant trunk retrieval becomes challenging. This paper presents a case of successful frozen elephant trunk retrieval by partial clamping of the descending aortic aneurysm without dissection of peri-aneurysmal adhesions, and subsequent encircling.
