Successful factor XIII administration for persistent chylothorax after lung transplantation for lymphangioleiomyomatosis.

Lung transplantation has emerged as a viable treatment option for patients with end-stage lymphangioleiomyomatosis (LAM), and therapeutic outcome results reported thus far have been satisfactory. However, persisting chylothorax after transplantation for LAM remains a challenging problem, and the optimal management has not been decided. We present the case with persistent chylothorax after lung transplantation for LAM, in which the intravenous administration of a tissue repair factor (human factor XIII) resulted in complete resolution of chylous effusion without performing additional invasive treatments, leading to a successful transplant outcome.
