After right common carotid-to-left common carotid arterial bypass with an 8 mm polytetrafluoroethylene (PTFE) graft, TEVAR
with zone 1 landing was performed through the right femoral artery by surgical dissection.
There is likely to be a trend towards aggressive TEVAR
management in patients with BTAI.
Like the abdominal version, the thoracic system can be used during de novo (initial) TEVAR
procedures to enhance an endograft's inherent fixation and sealing mechanisms.
This case illustrates some of the obstacles many surgeons and facilities still face when trying to perform TEVAR
The chimney technique with selective or bail-out conditions was used to extend the proximal landing zone in TEVAR
can be used in select patients to repair type B dissections and thoracic aneurysms.
The TAA HeliFX will allow surgeons greater control over the fixation and positioning of TEVAR
devices and has promise for significantly reducing the susceptibility of TEVAR
to the devastating consequences of late failure resulting from migration or aortic dilatation.
sup], Although several controversies continue to exist regarding the optimal treatment strategy for type B-AD, the recent interdisciplinary expert consensus document suggests that TEVAR
should be used for complicated cases with suitable anatomy to decrease the mortality and morbidity of open surgery, whereas medical management with close follow-up is the best strategy for uncomplicated type B-AD.
The recent launch, in mid-2008 of Cook's Zenith TX2 and Medtronic's Talent in the US coupled with the opening of Japanese market to TEVAR
devices fueled growth as many patients not eligible for open surgery entered the endovascular patient pool.
The patient underwent TEVAR
procedure because of Stanford type B aortic dissection 5 years ago.
According to the company, Zenith Alpha Thoracic will allow physicians to treat more patients with TEVAR
(thoracic endovascular aortic repair) because of its lower-profile introduction system and broad range of sizes.
As a result, these physicians were already familiar with TEVAR
and quickly switched to the newly approved devices.
