Postoperative Early Hemolytic Anemia due to Inverted Teflon Felt Strip after Emergency Repair for Type A Dissection

Abstract

A 39-year-old man underwent emergency surgery for type A acute aortic dissection complicated by paraplegia. However, hemolytic anemia increased significantly due to severe stenosis of the proximal anastomosis one month after surgery. He finally underwent a redo procedure 4 months after the initial operation whereupon it was verified that half of the inner felt strip used for proximal stump fixation had turned up and was protruding into the inner lumen. We report here on a rare case of survival of postoperative early hemolytic anemia due to severe graft stenosis caused by an inverted inner Teflon felt strip without any extra vascular compression.
