Semi-Clamshell Approach with Rib-Cross for Infected Hybrid TEVAR

Abstract

A single-stage extensive aortic replacement is necessary for infected stent graft explantation after thoracic endovascular aortic repair (TEVAR). However, establishing selective cerebral perfusion and antegrade myocardial protection while ensuring a clear view of the distal aorta is challenging. We adopted a semi-clamshell approach with rib cross for a case of infection following hybrid TEVAR. This approach provides visualization of the ascending aorta, aortic arch, and the descending aorta down to the diaphragm. It is a viable option for cases requiring total arch and distal descending aorta replacement, offering reliable cerebral and myocardial protection, particularly in open conversion of hybrid TEVAR.
