title: Split lung transplantation with intraoperative extracorporeal membrane oxygenation (ECMO) support.
abstract: Pulmonary bipartitioning or split lung transplantation, which was first described in 1997, presently represents the most efficient use of donor lungs. With this technique, a left donor lung can be separated into an upper and lower lobe and used for bilateral transplantation in a smaller recipient. The right donor lung remains for use as a single lung graft in another patient. In 2001, a similar technique for splitting a right lung was described. The technique of harvesting and procurement of the donor organ for split lung transplantation is identical to the standard lung transplantation technique. The final separation of the donor lung is performed at the level of the interlobar fissure immediately prior to implantation. The lower lobe is implanted in the left recipient hemithorax, whereas the upper lobe, after closing of the central end of the left main pulmonary artery, and a 180° rotation along the vertical axis, is grafted into the right hilus. The use of extracorporeal membrane oxygenation (ECMO) provides intraoperative hemodynamic stability and protects the first implanted lobe from overflow and resulting reperfusion injury. This report discusses the technique developed at the department of cardiothoracic surgery of the Medical University of Vienna.
