초록

The aim of this study is to evaluate the efficiency of the pulmonary perfusion scan(Pp scan) in the experimental animal single lung transplantation. Eight left lung transplanted mongrel dogs were included in this study. The serial Pp scan with 111MBq $^{99m}TC-MAA$ were done at the periods of immediate postoperative period, POD 3 days, and POD 10-14 days and finally autopsy was done in each cases. The transplanted lung perfusion was analysed as a percentage radioactivity of trans planted/native lung(T/N) ratio. The Pp scan of a donor mongrel dog was used as a reference(left/right lung (T/N) ratio 85.2%). The average T/N ratio of all cases on immediate postoperative state(reperfusion injury) : 19.2%, three acute rejections. 12.6%, three bronchial dehiscences 6.1% and two pulmonary thromboses : 2.0%. Two cases showed moderate improvement of reperfusion injury as increasing the T/N ratio in POD 3 days Pp scan. The T/N ratio showed sequentially decreased in six cases. As a conclusion, the Pp scan could be a non-invasive method in the evaluation of the experimental one-lung transplanted mongrel dog.
