Modified technique of isolated left lung perfusion in the rat

Isolated lung perfusion is a novel therapy for the treatment of pulmonary metastases to increase current low survival rates. Due to tumor heterogeneity, perfusion has to be evaluated in different rat species for efficacy and ideal drug regimens. The revised technique of isolated left lung perfusion as described by Wang and originally performed in the Fisher rat resulted in a high morbiditity in the Wag/Rij rat in our laboratory. Therefore, we modified techniques for intubation and anesthesia, and developed a new approach of catheterization with improved results.
