Fulminant hepatic failure is a life-threatening event with a high mortality rate up to 80%. Orthotopic liver transplantation has markedly decreased this mortality rate and is therefore a well established procedure for hepatic failure. However, this treatment neglects the fact that patients surviving hepatic failure without liver transplantation experienced a complete morphologic and functional recovery of their own liver. Temporary support of liver function in such cases could therefore be desirable and adequate therapy. Auxiliary liver transplantation could fulfill this demand. However, the standard technique of auxiliary grafting, transplanting a graft in a heterotopic position, is burdened by problems such as elevated venous back-pressure, insufficient respectively competing portal blood supply for both livers with an unpredictable long-term outcome. In order to cope with these problems, we performed an auxiliary transplantation in an orthotopic position. To accomplish this procedure we had to reduce the size of both the recipient and the donor livers. We, thus, performed an auxiliary partial orthotopic liver transplant (APOLT). The first patient was a 33 year old female who was transplanted on November 25, 1989. She developed a HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome and fell into a deep coma. At the time of transplantation histologic examination of her own liver revealed 80% confluent necrosis. We resected segments 2 and 3 of the recipient liver and transplanted the whole left lobe of the donor liver into this position.(ABSTRACT TRUNCATED AT 250 WORDS)

The aetiology of arrhythmogenic right ventricular dysplasia is still unknown, and there are few reports on familial coincidence in the literature. A case of a previously healthy man with an episode of acute myocarditis is described. After recovery from acute myocarditis, the patient was resuscitated from aborted sudden cardiac death 16 months later. Angiographic and electrophysiological evaluation suggested the pattern of arrhythmogenic right ventricular dysplasia. The case seems to suggest that arrhythmogenic right and/or left ventricular dysplasia could be mimicked by chronic (or healed) myocarditis.
