We have occasionally observed a bubble leaving the suture line of an open stent graft; hence, we hypothesized that de-airing an open stent graft could potentially reduce spinal cord injury. Postoperative computed tomography often showed residual air in thoracic aortic aneurysms, confirmed by the presence of a certain amount of air in an open stent graft in a dry lab. We filled CO2 in the sterilized package of an open stent graft and subsequently filled it with saline, which absorbed the CO2 and entered into the gap of the graft. The clinical benefit of de-airing an open stent graft to reduce the incidence of spinal cord injury needs to be evaluated.
