[Endovascular stent-graft exclusion of giant and long-segment thoracic aortic aneurysms].
OBJECTIVE
To discuss the availability of endovascular stent-graft exclusion in giant and long-segment thoracic aortic aneurysms.


METHODS
Endovascular stent-graft exclusion was performed on 3 male patients with giant and long-segment thoracic aortic aneurysm. Multiple stent-grafts were connected as a long stent-graft to repair these thoracic aortic aneurysms, of which one with 28 cm in length and 7.3 cm in maximum diameter was excluded by 4 stent-grafts with different diameters and same length of 130 mm. The preliminary bypass between right common carotid artery and left common carotid artery or left common carotid artery and left subclavian artery was performed on 2 patients.


RESULTS
Three patients underwent the operation successfully, and achieved the good results. There was no endoleak at the conjunction of stent-grafts in 2 cases, and a little endoleak in 1 case, which disappeared 1 year after operation. One case presented temporal cerebral ischemia, which disappeared after 1 month.


CONCLUSIONS
The endovascular deployment with multiple stent-grafts connection is a safe, mini-invasive and effective therapeutic method for giant and long-segment thoracic aortic aneurysm, but long-term outcomes will be gotten after the follow-up study.
