5 Fig. 4 Typical motor-evoked potential (MEP) registrations of left and right anterior tibial muscles. 1, Crossclamps at T5 and L1; decrease of MEPs. No improvement despite increased distal aortic pressure. 2, Proximal anastomosis and reattachment of intercostal arteries T8 and T9 accomplished. No improvement of MEPs 3, Selective Dacron graft to T12 and selective perfusion with gradually improving MEPs. 4, Restored MEPs.
