    Notes: Abstract  Background: From September 1988 through April 1998, 1000 liver transplantations were performed on 911 patients. The standard technique for liver re-vascularization to guarantee an optimal blood inflow during transplantation was modified in 19% of the cases on the arterial side and in 5.6% of the cases on the portal side as a result of unusual anatomical features and pathological changes in the vasculature of the organ recipient.In 113 transplantations, successful reconstruction of accessory vessels of the graft (12 left and 101 right hepatic arteries) was performed without complications. It is our opinion that preoperative diagnosis of the vasculature (stenoses of the celiac trunk etc.) of the organ recipient by duplexsonography and angiography is necessary. Even with the help of these tests, it is extremely difficult to diagnose a ”steal” syndrome in the splenic artery: for example, 31 of 40 patients with poor liver function received postoperative therapy for newly diagnosed ”steals”. Results and conclusions: There is no increase in complications (stenosis and thrombosis) with modifications of arterial reconstruction (4.9 vs 6.3%); however, with modification of portal reconstruction the increase is from 2.4% to 8.3%.

    Notes: Abstract From September 1988 through April 1998, 1000 liver transplantations were performed on 911 patients. During the postoperative control examinations of 837 patients, we found 23 (2.74 %) with hepatic artery thromboses, 27 stenoses of the hepatic artery (3.22 %), and 6 aneurysms of the graft artery. Seventeen patients underwent retransplantation because of arterial complications. Depending on the clinical symptoms, we treated both the local situation as well as the resulting complications of inadequate arterial graft flow. The aneurysms were primarily treated surgically. The first choice of treatment of stenoses was balloon angioplasty. Early postoperative artery thromboses were also treated surgically by thrombectomy in selected cases. For the resulting biliary and local septic complications we preferred endoscopic and drainage procedures. Our clinical experiences have led us to find pretransplantation angiography recommendable, especially in the case of splanchnic artery stenoses, for bypassing from the aorta for arterial perfusion of the graft.
