[Long-term outcomes of thoracic endovascular aortic repair with homemade stent-grafts].

We reviewed our experience with homemade stent-grafts in the repair of thoracic aortic lesions. The objective of this study was to assess the long-term outcomes of this therapy. From 1999 to 2008, homemade stent-grafts were inserted in 94 patients with various thoracic diseases. The endoprostheses were stainless steel Z-stents covered with polyester graft and were custom designed for each patient. Placement of the stent-grafts was technically successful in 85 of the 94 patients (90%). Within 30 days after the treatment, 4 patients died, 3 had cerebral infarction, and 3 had the onset of paraplegia or paraparesis. Primary endoleaks were observed in 10 patients (11%). During the mean follow-up period of 43 +/- 29 months, 10 patients had endoleaks and 8 had stent-graft migration. The aneurysm-related mortality rate was 12%. Our early outcomes of elective and emergency thoracic endovascular aortic repair with homemade stent-grafts demonstrated their therapeutic effectiveness in high-risk patients with various thoracic diseases. Endoleaks and migration were, however, the factors most responsible for secondary intervention in the mid-term period. Careful follow-up of the treated patients is needed to avoid the major complication in the long-term period.
