ABSTRACT
The aims of this study are to settle and verify how trustful is the heterotopic transplantation of the heart in an experimental model utilizing the original technique of Abbott modified by Ono and Lindsey distinguishing from it for the administration of the anaesthesia and the preservation of the organ. In this type of operation is necessary to realize only two micro-surgical vascular anastomosis that represent the basis of any other micro-surgical operation of organ's transplantation in the rat. There have been used 30 rats of the Wistar stock of male sex and weighing about 200-300 grs. both as donor and as receiving. The anaesthesia consisted in the administration of methoxyflourane by inhalation during the operation. The heart is kept in a container with Stanford solution on ice. The 77% of the cases (23 on 30) have been successful, even considering the ischaemic damage that has been evaluated examining the cardiac beat and the color of the organ. The study of Ono and Lindsey gave as result the success of the operation on 91% of cases (147 on 161 operated), compared to the result obtained by us, on a smaller number of cases (77% of success on 30 operated rats) permits to consider this experimental model to be utilizable even for further more complex studies.
