Organ Transplant Duplex Scan and Doppler Color Flow Imaging

Duplex Scanning and Doppler Color Flow Imaging have been shown to be valuable procedures for evaluation of transplanted organs. These techniques were first used for kidney transplants at this institution to confirm normal flow patterns and are very helpful for demonstrating acute rejection, acute tubular necrosis, transplant renal artery stenosis, and other vascular disorders of the transplanted organ.

Similarly, the circulatory patterns can be demonstrated in pancreas and liver transplants and the patency of the vessels confirmed.

The technique for examination is similar to that described in the preceding section for Visceral Vessel Duplex Examinations. Fasting prior to the examination is required only for those patients who have received a liver transplant. You may be evaluated before being discharged from hospital following surgery and at least every three months throughout the first post-transplant year to assure the continued health of the organ.
