Abstract

When performing living-donor lobar lung transplantation on small children of height 100 cm or under, accommodation of an oversized adult lobar graft is problematic, sometimes necessitating single lobar transplantation in combination with contralateral pneumonectomy. We here report a unique case of living-donor lobar lung transplantation in a 9-year-old boy with congenital pulmonary hypoplasia. Although he was 104 cm tall, and the available adult lower lobe graft appeared to be oversized, his right lung was hypoplastic, resulting in his mediastinum being shifted to the right and thus already showing “postpneumonectomy-like” anatomy. His father’s left lower lobe was successfully transplanted into the left thorax without performing a contralateral pneumonectomy. Three-dimensional reconstruction of computed tomography images and computed tomography volumetry were extremely helpful in matching the size of the graft and planning this unique surgery.
