title: Combined endovascular stent-graft repair and adjunctive visceral vessel reconstruction for complex thoracoabdominal aortic aneurysms.
abstract: OBJECTIVE
  This study demonstrates the therapeutic value of the hybrid open and endovascular procedure in anatomically challenging thoracoabdominal aortic aneurysms (TAAAs) in high-risk patients.
  
  
  METHODS
  Between January 2000 and February 2006, 8 patients were treated with open visceral vessel revascularization and endovascular repair for TAAAs. Patient data were available from medical records. Pre- and postoperative physical examination, intra-arterial angiography, and spiral computed tomography scanning was performed in prearranged examinations.
  
  
  RESULTS
  A total of 28 visceral bypasses were performed in the 8 patients: 6 patients with complete visceral vessel revascularization and 2 with an aorto-mesenteric-celiac bypass. Aneurysm exclusion was achieved through the deployment of in total 23 stent-grafts. Seven out of the 8 procedures were conducted electively and one under urgent conditions. The mean follow-up period was 21 months. We recorded one procedure-related death due to postoperative hemorrhage resulting from diffuse retroperitoneal bleeding with consecutive multiorgan failure. Moreover, one patient developed acute renal insufficiency, but returned to normal values after temporary hemodialysis. Major adverse events included 2 cases of pneumonia and one myocardial infarction. Two reoperations were performed due to one mesenteric bypass occlusion and one groin hematoma. No neurological complications were observed.
  
  
  CONCLUSIONS
  The combined hybrid endovascular and open surgical approach in the treatment of complex TAAAs remains a feasible and effective operation technique. The less invasive character of the procedure and avoidance of aortic-cross clamping are clear advantages. Nevertheless, further study is mandatory to establish this alternative therapeutic option for complex TAAAs.
