title: Angiographically determined arteriopathy in liver graft dysfunction and survival.
abstract: We evaluated the contribution of flush and selective hepatic angiography in defining the extent and pattern of major vessel and microvascular arterial lesions and their significance in graft survival. The 50 consecutive patients investigated comprised three clinical groups: Group A (n = 18) were patients with severe graft dysfunction within the first seven days post-transplantation. In this group six of 18 angiograms demonstrated intrahepatic attenuation of the arterial tree suggestive of acute cellular rejection and four of these grafts were lost, compared to a 78% graft survival in the non-arteriopathic group. Group B (n = 16) comprised patients with clinically suspected hepatic arterial thrombosis or stenosis, these diagnoses were confirmed in all patients compared to only 10 positive findings with doppler ultrasonography. Graft survival was only 10% in those patients with artery thrombosis as compared to 100% in those with arterial anastomotic stenoses. Group C patients (n = 16) had histologically confirmed chronic allograft rejection and in ten of them (65%) evidence of arteriopathy was demonstrated despite histological evidence of arteriopathy being present in only 19% of patients. All patients in this group with arteriopathic changes lost their grafts with the exception of one successfully treated with FK506. In two other patients reversibility of chronic rejection was observed, neither of whom had evidence of an arteriopathy.
