Background:
Retrograde type A aortic dissection is a rare but deadly complication after thoracic endovascular aortic repair of type B aortic dissection. Total arch replacement combined with a modified stented elephant trunk technique (SET), was performed for these complicated dissections. We reviewed our results of the procedure for this serious complication, aiming to evaluate the feasibility of the technique.
Methods:
Between April 2005 and September 2012, 24 patients with retrograde type A aortic dissection after thoracic endovascular aortic repair underwent the SET procedure in our center. The mean age at operation was 44.1±8.8 years old. Postoperative mortality and morbidity were analyzed to evaluate the immediate and mid-term results.
Results:
Death at 30 days was 4.2% (1 of 24 patients). No patient suffered paraplegia or stroke after operation. Follow-up was completed with 23 survivors. The mean follow-up period was 32.2±13.1 months (range, 12 to 49 months). No late deaths occurred during follow-up. One patient underwent reoperation for replacement of the thoracoabdominal aorta and enjoyed an uneventful survival.
Conclusions:
The stented elephant trunk technique could be an alternative for treatment of retrograde type A aortic dissection with acceptable surgical risks and satisfactory results.
