Endovascular technologies represent major advancements in treating descending thoracic aortic aneurysms (DTAA). We compared hospital charges of open thoracic aortic replacement (OTAR) with endovascular repair of thoracic aortic aneurysms (TEVAR).


Retrospective analysis of hospital charges related to repair of DTAA (2000-2009). Charges were inflation adjusted for dollars in 2009.


There were 50 OTAR and 50 TEVAR patients. Open thoracic aortic replacement charges were $64 531 (interquartile range [IQR]: 49 000-108 515) versus $61 909 (IQR: 41 307-92 109) for TEVAR(P = .4). A total of 10 patients (10%) died before discharge, with 0 TEVAR deaths (P < .05). For OTAR, supply charges ($9167) accounted for 13% of total charges versus 56% for TEVAR ($40 468), P < .01. Open thoracic aortic replacement length of stay (LOS) was 12 days (6 days intensive care unit [ICU] stay); bed charges comprised 40% of the total charges. Thoracic endovascular aneurysm repair had lower LOS (5days with 2 days ICU stay, P < .001).


Descending thoracic aortic aneurysm repair remains a formidable operation with significant resource utilization. Thoracic endovascular aneurysm repair does not significantly reduce overall hospital charges due to device costs but demonstrates improved mortality, ICU, and total LOS.
