Overview

Retrospective study demonstrates favorable survival for donor aorta reconstruction during lung transplantation for giant aneurysms, indicating a safe surgical strategy.

Key Points

  • Evaluate short- and long-term outcomes of bilateral lung transplantation combined with pulmonary artery reconstruction using donor aorta in patients with pulmonary arterial hypertension and giant pulmonary arterial aneurysms.
  • Retrospective single-center study analyzed 19 adult patients with pulmonary arterial hypertension receiving cadaveric bilateral lung transplantation between January 2010 and December 2020.
  • Compared 5 patients with giant aneurysms (median trunk diameter, 69.9 mm) receiving pulmonary artery reconstruction using donor aorta against 14 patients receiving standard bilateral lung transplantation without reconstruction.
  • Operative time was longer in the reconstruction group compared with standard transplantation (1239 vs 958 minutes, P = 0.087).
  • Short- and long-term outcomes showed 90-day mortality was 0% in the reconstruction group versus 14.3% in the standard group (P > 0.99), and 5-year survival was 100% versus 85.7% (P = 0.74).
  • No aortic graft dilation, constriction, or infection occurred during a median follow-up of 94 months in the reconstruction cohort.
