Human En Bloc Double-Lung Transplantation: Bronchial Artery Revascularization Improves Airway Perfusion Arve Sundset, Samad Tadjkarimi, Asghar Khaghani, Knut Kvernebo, Magdi H Yacoub The Annals of Thoracic Surgery Volume 63, Issue 3, Pages 790-795 (March 1997) DOI: 10.1016/S0003-4975(96)01273-8 Copyright © 1997 The Society of Thoracic Surgeons Terms and Conditions
Fig. 1 Perioperative perfusion values in the double-lung transplant (DLTx) group compared with the group of patients with coronary heart disease, given as arbitrary perfusion units (PU). The horizontal lines indicate median values. Measurements in the trachea were performed in the native airways in the double-lung transplant group.

Fig. 2 Laser Doppler recording in the left upper lobe. The recorded curve shows fluctuations synchronous to pulse (small “spikes”) and respiration (larger “waves”). Repeated clamping (arrows) of the attached internal thoracic artery induced a substantial reduction in the laser Doppler flowmetry output signal. (PU = arbitrary perfusion units.)

Fig. 3 Effect of clamping of the attached internal thoracic artery on transplant airway perfusion. Each cross indicates the clamping effect in each patient. The reduction of the laser Doppler flowmetry signal during clamping is given in percent of baseline before clamping.

Fig. 4 Spatial variation, expressed as the coefficient of variation of repeated measurements in each region. The horizontal lines indicate median values. (DLTx) = double-lung transplant group.)
