Rapidly progressive atherosclerosis after domino liver transplantation from a teenage donor with homozygous familial hypercholesterolemia.

Familial hypercholesterolemia (FH) is an autosomal dominant disorder characterized by impaired clearance of low-density lipoprotein cholesterol. Given limitations in pharmacologic therapy and the significant morbidity and mortality associated with this disease, liver transplantation may be offered to select homozygous FH patients in childhood in an effort to slow progression of atherosclerotic cardiovascular disease. In rare cases, domino liver transplantation can be performed, transplanting the livers of patients with various metabolic disorders into elderly recipients whose projected survival precludes prolonged waiting on the transplant list. Herein, we report a case of domino liver transplantation using the liver of a 14-year-old boy with homozygous FH into a 65-year-old man with primary sclerosing cholangitis and cirrhosis who developed rapidly progressive atherosclerotic cardiovascular disease involving the arteries of his proximal bilateral lower extremities, carotid arteries and superior mesenteric artery.
