Abstract: | Arteriography was routinely performed in patients with suspected vascular complications after pancreas transplantation. Dysfunction of the grafts was suggested by 99mTc-DTPA scanning and metabolic tests. Thirty arteriograms obtained in 25 patients were evaluated. Nineteen conventional film angiograms and 11 intraarterial DSA were performed. Five different angiographic patterns were observed: normal vascular anatomy, low-flow phenomenon, arterial or venous thrombosis, and venous neovascularity. On the basis of the angiographic findings, various reasons for graft failure were identified. Recipient venous collaterals or well-functioning grafts without angiographically detectable blood supply were observed in 9 cases, and must be considered to represent neovascularisation by donor and recipient vessels. |
