Thoracic Endovascular Stent Graft Implantation Efficacy

Objectives: Thoracic aortic aneurysm (TAA) is an uncommon disease with an incidence of 10.4 per 100,000 and dissection is the major complication of TAA.The treatment of aortic diseases is surgery.In recent years, endovascular stent graft (EVSG) application has been performed for many reasons, especially due to its low complications in the treatment of aortic aneurysm and dissection.The aim of this study is to evaluate the efficacy, treatment results, and complications EVSG implantation.Methods: A total of 34 patients with thoracic aortic disease who underwent stent grafting between August 2004 and January 2011 were included in the study.The patients' diagnoses and risk factors were recorded.Complications of the procedure and the presence of postprocedural leakage were evaluated.The patients were followed up with computed tomography angiography. Results:Of the 34 patients who underwent the procedure, 16 had no early, late complications and no leakage, whereas eight required additional stenting and other intervention.During follow up three patients showed acute cerebral infarction and four patients have hospital infections.A total of 7 patients had endoleaks occurred and repair with additional interventions.The average hospital stay is 5.8 days.The mortality rate in the hospital is 11.7%. Conclusion:The EVSG treatments of acute and chronic thoracic aortic diseases in appropriate patients is an alternative and safe method to surgery with high technical success, low complication rates.
