In our opinion, the use of MiECC in urgent CABG procedures is safe, feasible and shows no disadvantages compared with the use of CECC. Emergency operations using the MiECC system showed a significantly lower blood transfusion rate and better results concerning the unadjusted in-hospital mortality.
We report about a 61-year-old man who, 6 years after initial uncomplicated mitral valve repair and 3 months after treatment of a pseudo-aneurysm of the ascending aorta with a Dacron patch, was admitted in our institution with an infection of the vascular graft, which was associated with sternal osteomyelitis and purulent cutaneous fistula. In a re-redo procedure, the proximal aortic arch and the ascending aorta were replaced with a cryopreserved aortic homograft. The infected part of the sternum was resected and the defect was covered by mobilizing the mediastinal tissue and with a bilateral muscle flap. The patient was discharged 20 days after surgery. This treatment concept outlines the benefit of cryopreserved aortic homograft when faced with a complex thoracic aortic infection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
