PURPOSE: To evaluate the technical success, feasibility, and outcomes of endovascular preservation of segmental arteries (SAs) during fenestrated/branched endovascular aortic repair (F/B-EVAR).
MATERIALS AND METHODS: A multicenter, retrospective study was conducted in consecutive patients treated with F/B-EVAR and a branch or fenestration for SA preservation. Eleven patients (median age, 57 years; range, 45-73 years; 7 men) were included.
RESULTS: Twelve SAs were preserved. Stent grafts were custom made with fenestrations, branches, or a combination of both in 1, 2, and 5 patients, respectively. A t-Branch stent graft was used in 2 patients, and a physician-modified thoracic stent graft with a branch was used in 1 patient. Eight branches and 4 fenestrations were used for the preservation of 12 SAs. Four fenestrations and 1 branch for the SAs were not bridged and were left for perfusion of the corresponding SAs. Technical success was achieved in 10 of 11 (91%) patients. No early mortality occurred. Early morbidities included renal insufficiency without dialysis in 1 patient and partially delayed paraplegia in 1 patient. Before discharge, computed tomography angiography (CTA) showed patency of all the SAs. The median follow-up duration was 30 months (range, 10-88 months). Late death occurred in 1 patient. Two SAs were occluded in 1 patient with 2 unstented fenestrations, as determined using 1-year follow-up CTA. This patient did not develop spinal cord ischemia (SCI). Other SAs remained patent during follow-up. One patient with a type IIIc endoleak was treated by relining of bridging stents.
CONCLUSIONS: Endovascular preservation of SAs with F/B-EVAR for thoracoabdominal aortic aneurysm is feasible and safe in select patients and may add to preventive measures for SCI.
