The use of stent grafts for the treatment of aneurysms and dissections of the thoracic aorta: a single centre experience.

OBJECTIVE

To review the results of stent graft treatment for diseases of the thoracic aorta.

DESIGN

A retrospective study of the results of thoracic stent graft procedures in a single centre.

METHODS

The results of 30 procedures performed in 24 patients were analysed. Eleven patients had aneurysmal dilatation of the descending thoracic aorta (>5.5 cm), nine patients had complicated type B dissection, three had penetrating ulcers and one had a traumatic pseudoaneurysm. Imaging follow-up consisted of CT scans performed at one, three, six and 12 months following the procedure and annually thereafter.

RESULTS

One technical failure occurred due to a ruptured external iliac artery. There were no other immediate failures. The primary technical success rate was 83%. The 30-day procedural and patient mortality rates were 7 and 8%, respectively. No neurological complications occurred. Seven patients had the subclavian artery covered without complications. Secondary intervention was required in 21%. During the follow-up period (mean 11 months, range 1-48 months.) there were five deaths, two of which were related to stent graft infection.

CONCLUSION

Thoracic stent grafts offer a realistic alternative to surgery.
