The management of melioidosis, caused by Burkholderia pseudomallei, presenting as an infected pseudoaneurysm requires radical debridement and prolonged antibiotics because the pathogen is resistant to host immunity. An extra-anatomical bypass might be a better treatment choice than in situ graft interposition or other methods. We report on a 76-year-old man with an infected pseudoaneurysm located in the innominate artery and a method of extra-anatomical bypass that has not yet been reported in the literature. The patient recovered well without recurrence of infection after the surgical procedure.
