Purpose
In certain patient populations endovascular stentgraft treatment of the ascending aorta is feasible.
This single-center report details the experience with this interventional method in patients with type A aortic dissections or pseudoaneurysms.
Methods and Materials
Comorbid patients who were not fit for open surgery were selected for endovascular repair.
Technical success (proper position,
full deployment and pathology exclusion) and stability of results during and after intervention were the primary endpoints .
The secondary endpoints consisted of length of intervention,
total radiation exposure and freedom from peri-/post-interventional complications.
Protocols and medical records were reviewed,
follow-up was performed by CT and patient status was assessed by telephone interviews.
The stentgrafts utilized were: Relay ascending Gen I and Relay ascending Gen II,
Bolton...
Results
After a mean follow-up of 25.8 ± 34.0 months primary technical success was achieved in 2 of 5 patients,
assisted technical success in 3 of 5 patients and sustained clinical success in 3 of 3 patients.
At intervention mean patient age was 71.5 ± 13.9 years.
One patient expired during the intervention,
while another required a second stentgraft due to pseudoaneurysm rest-perfusion.
In one patient the stentgraft was not deployable in spite of ideal positioning.
Meanradiation dose,
fluoroscopy time andintervention time were21189.3 ± 14255.1 cGy/cm2and...
Conclusion
In selected patient populations the endovascular repair of pseudoaneurysms and type A aortic dissections may represent an interventional alternative to open surgery.
