A Dacron wrap aortoplasty has been described as an adjunct to reduction ascending aortoplasty for the repair of Type A aortic dissections. We report a case of an uncomplicated hemiarch repair with wrap aortoplasty of the distal anastomosis which resulted in severe acute hemolysis. Despite only minimal focal graft deformation on imaging, the patient was found to have a flow gradient across the distal anastomosis, which was reduced by > 50% following release of the outer graft wrap. To our knowledge, only 29 additional cases of hemolytic anemia following aortic dissection repair have been described in the English literature. The reported mechanisms included aortic graft stenosis (50%), graft kinking (23%), external compression of the graft (20%), and a folded elephant trunk appendage (7%). The mean onset of hemolysis following aortic dissection repair occurred 32.2 ± 44.4 months after surgery, with only 16.7% of cases occurring within 2 weeks. This review details the clinical, laboratory, and imaging findings suggestive of mechanical hemolysis following aortic surgery.

Benign esophagectomies are associated with significant morbidity. Although the site of the anastomosis does not alter outcomes, use of colon/intestine conduit should be pursued with caution.
