Hybrid Thoracoabdominal Aortic Aneurysm Repair: An Experience at Chiang Mai University Hospital
Keywords:Thoraco-abdominal aneurysm, hybrid repair, visceral de-branching
AbstractPurpose: To present a case series of patients with thoracoabdominal aortic aneurysm (TAAA) who were treated
with the hybrid repair technique.
Materials and Methods: From January 2009 to April 2013, TAAA patients who were treated with the hybrid repair
technique were retrospectively reviewed.
Results: There were three cases of hybrid repair performed during the study period. Aneurysm morphology
included type IV TAAA in two patients and suprarenal in one patient. The average aneurysm diameter was 82.6 mm
(range 73 to 91 mm). Technical success was obtained in all patients. Graft thrombosis occurred at a rate of 30% (3 in
10 visceral bypass grafts), which resulted in mesenteric ischemia and transient renal insufficiency. The average hospital
length of stay was 53 days, with a median ICU stay of 11.3 days.
Conclusion: Hybrid surgery could be considered a bridging measure between open and fenestrated/ branched
endograft. The surgical technique will remain a robust and adaptable method of treating this complex and lifethreatening
disease in individuals with unfavorable anatomy.
