| Abstract: | A prospective study of duplex Doppler ultrasound in 29 renaltransplants was undertaken to determine how to interpret Dopplerfindings in the immediate postoperative period. The study includedintraoperative pulsed Doppler recordings from grafts immediatelyfollowing release of vessel clamps. Subsequent follow-up studieswere performed in the immediate postoperative period. IntraoperativeDoppler appearances in the group as a whole were normal; therewas a significant deterioration in Doppler appearances in thefirst 2448 h of the postoperative period. In the absenceof rejection subsequent Doppler appearances returned to normal.An abnormal Doppler appearance immediately following transplantationshould be an expected result. If the Doppler fails to improve,or deteriorates having started to improve, rejection shouldbe strongly suspected. |
