Abstract

|
|
We experienced 7 cases of left single lung transplantation in 14 mongrel dogs and analyzed graft lung function by hemodynamics, blood gas analysis, chest X-ray, biopsy and perfusion lung scan. We performed right pulmonary artery cuff (PA cuff)
for
analysis of graft lung function in 3 cases. The donor lungs were flushed with modified Euro-Collins solution (n=3) or low potassium dextran glucose solution (n=4) and preserved for 4 to 5 hours (n=4) or 24 hours (n=3) at 10℃ and implanted to the
dogs
with similar weight. Assessment of left graft lung was done by occluding the right pulmonary artery for 10 minutes using PA cuff. Assessment for graft lung function was done immediately after an operation and after 3 days, 7 days and 3 weeks
postoperatively. Four dogs survived for 3 days, 7 days (2 cases) and 3 weeks respectively. Other three dogs expired within 3 hours of reperfusion. Immediate perfusion scans of left lung in four survived dogs after reperfusion were 42.1%, 36%, 11%
and
5.9% respectively, and another dog with 4.8% perfusion to left lung was dead due to left atrial thrombi after 3 hours reperfusion. In one case among three acute rejections follow-up perfusion scan was done on 3rd and 11th postoperative day nd the
result
decreased from 36% perfusion immediate postoperatively to 21% and 15% respectively. Three expired dogs postoperatively couldn't tolerate occlusion of right pulmonary artery with above 40mmHg of mean pulmonary artery pressure. On the other hand,
three
survival dogs postoperatively tolerated occlusion of right pulmonay artery with less than 30mmHg of mean pulmonary artery pressure. And one dog couldn't tolerate same procedure immediate postopertively but in 2 hours reperfusion later tolerated
with
29mmHg of mean pulmonary artery pressure.
In conclusion we couldn't compare the effect of two flushing solutions but low potassium dextran glucose solution showed relatively safe preservation effect in cases with preservation of more than 20 hours. Also canine left single lung
transplantation
model with PA cuff indicated useful method for the assessment of graft lung function with effect of lung preservation.
