Kidney Autotransplantation and "Debranch-First" Technique for Thoracoabdominal Stent-Graft Infection: Surgical Management of a 22-Year-Old Man With Midaortic Syndrome and Infection of Aortic and Renal Stent Grafts.

OBJECTIVE

To present the surgical management of a 22-year-old patient with midaortic syndrome, symptomatic for claudication and renovascular hypertension, with infected aortic and renal stent grafts.

KEY STEPS: Procedures were performed as follows: 1) right renal autotransplantation through a transperitoneal approach and midline abdominal incision; 2) thoracotomy with left visceral rotation and visceral vessel exposure; 3) left-heart bypass and "debranch-first" technique, with warm blood perfusion for the splanchnic vessels and cold Custodiol solution for renal perfusion; 4) aortic replacement with a tubular xenopericardium graft; and 5) separate reattachment of visceral vessel to the main tubular graft.

POTENTIAL PITFALLS: Recurrent infections of the xenopericardium graft, kidney parenchyma loss, and major complications such as spinal cord ischemia, represent potential pitfalls to this procedure.

TAKE-HOME MESSAGE: Kidney autotransplantation allows right renal-infected stent graft removal before in situ thoracoabdominal reconstruction through left thoracoabdominal access, preserving renal function against renovascular hypertension.
