Abstract

Background: We evaluated the operative outcomes of an extra-anatomic bypass from the ascending aorta to the abdominal aorta in patients with type II or III Takayasu arteritis (TA) with mid-aortic syndrome. Methods: From 1988 to 2014, 8 patients with type II (n=2) or III (n=6) TA underwent an ascending aorta to abdominal aorta bypass. The mean patient age was $43.5{\pm}12.2years$ and the mean peak pressure gradient between the upper and lower extremities was $54.8{\pm}39.0mm\;Hg$. The median follow-up duration was 54.4 months (range, 17.8 to 177.4 months). Results: There were no cases of operative mortality. The mean peak pressure gradient significantly decreased to $-2.4{\pm}32.3mm\;Hg$ (p=0.017 compared to the preoperative value). Late death occurred in 2 patients. The symptoms of upper extremity hypertension and claudication improved in all patients. The bypass grafts were patent at $47.1{\pm}58.9months$ in 7 patients who underwent follow-up imaging studies. Conclusion: An extra-anatomic ascending aorta to abdominal aorta bypass could be an effective treatment option for severe aortic steno-occlusive disease in patients with type II or III TA, with favorable early and long-term outcomes.
