“…The descending thoracic aorta and the abdominal aorta have previously been used as the inflow site. 7,8 The present case suffered from aortic dissection involving all parts of the thoracic and abdominal aorta, which precluded these alternative approaches. The reversed sequence supra-aortic debranching from femoral artery inflow has only been described in limited reports.…”

Hybrid Repair with Reversed Sequence Supra-aortic Debranching in Ruptured Arch Aneurysm

Aortic arch pathology in a high-risk patient in whom the resternotomy approach is unfeasible due to treated mediastinitis after ascending aortic replacement presents a unique challenge for hybrid arch repair (HAR) because of the need for supra-aortic debranching from unusual inflow sites other than the ascending aorta. This report describes a “reversed sequence” extra-anatomical supra-aortic debranching procedure as a salvage technique performed to enable HAR. An 83-year-old woman with a history of ascending aortic replacement for type A aortic dissection, mediastinitis complicated by sternal osteomyelitis, and a chest wall reconstructed with a rectus abdominis myocutaneous flap presented with chest pain because of a contained dissecting arch aneurysm rupture. The patient underwent supra-aortic debranching from the bilateral common femoral arteries and thoracic endovascular aortic repair to the ascending aorta under cerebral near-infrared spectroscopy (NIRS) monitoring. Completion imaging by angiography demonstrated successful exclusion of the ruptured aneurysm. The regional cerebral oxygen saturation level, monitored by NIRS, did not change markedly during surgery. The patient was neurologically intact with adequate cerebral blood flow assessed postoperatively by 123I-IMP single photon emission computed tomography. Total debranching of the supra-aortic vessels from the common femoral artery for inflow is feasible and provides adequate cerebral perfusion. This procedure may offer an alternative treatment option in patients with complex conditions involving aortic arch pathology.
