Risk factors for HD instability during surgery for pheochromocytoma include a high plasma NE concentration, larger tumor size, more profound postural BP fall after alpha-blockade, and a MAP above 100 mm Hg (130/85 mm Hg). Efficacy for preventing HD instability was identical for PXB and DOX.
Auxiliary heterotopic liver transplantation is theoretically attractive because it leaves the recipient's liver in place. The surgical trauma of hepatectomy is avoided, and failure of the graft does not necessarily lead to the death of the patient or a second, emergency transplantation. Another advantage is that matching the body sizes of the donor and the recipient is not mandatory, which increases the number of possible donors. However, previous clinical results of auxiliary liver transplantation have been poor. We performed auxiliary partial liver transplantation in six consecutive patients with end-stage chronic liver disease who were not accepted for orthotopic liver transplantation because they had massive ascites, deficient clotting function, cachexia, or poor pulmonary reserve. The donor liver was transplanted to the right subhepatic region after removal of segments II and III, and it was provided with portal and arterial blood. There were no major changes in hemodynamic measurements during surgery. The mean hospital stay after transplantation was 22.7 days (range, 14 to 29). After a mean follow-up period of 14 months (range, 5 to 23), all patients were alive, with good graft function as demonstrated by scintigraphy, Doppler ultrasonography, and synthesis of clotting factors. From these observations we conclude that auxiliary partial liver transplantation is an attractive alternative to orthotopic liver transplantation in high-risk patients. Its role in other patients who need liver transplants remains to be defined.
The use of solvent/detergent virus-inactivated plasma is of increasing importance in the prevention of human immunodeficiency virus and hepatitis C virus transmission. Since the use of this plasma during orthotopic liver transplantation has increased, the incidence of hyperfibrinolysis was observed. Clotting analysis of the patients revealed small alpha(2)-antiplasmin concentrations because of the solvent/detergent process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
