Background:
This study
describes our experiences and results of endoluminal stent graft placement in
the treatment of descending thoracic aortic aneurysms.
Methods:
Between November 1996 and August 2000, endoluminal stent graft repair was
performed in 41 patients. There
were 11 women and 30 men with a mean age of 66 years (range 33a to 87a).
Atherosclerotic aneurysms with a diameter of more than 6 cm represented the
indication in 32 patients (78%). In 2 patients (4,9%) stent grafting was
indicated because of a localized aortic dissection with an aortic diameter of
more than 6 cm and in 3 patients (7,3%) because of a perforated atherosclerotic
ulcer with the symptom of hemoptysis. In 4 patients (9,6%) an acute type B
dissection was treated. To allow safe deployment of the stent graft, preliminary
subclavian-carotid artery transposition was necessary in 10 patients (24,4%).
Talent™ stent grafts were used in 15 patients, Gore Excluder™ stent grafts
were implanted in 26 patients.
Results:
Successful placement of endoluminal stent grafts was achieved in all patients.
Two patients died postoperatively (mortality rate 4,9%), one due to aneurysmal
rupture, the second due to impaired perfusion of the celiac axis. Repeat
stenting was done in three patients because of intraoperative leakage.
Conclusions:
Endovascular stent graft repair is a promising and less invasive approach in the
treatment of thoracic aortic aneurysms. This technique can be performed with
excellent results, even in patients, which were unsuitable for conventional
surgery.
