Anatomical variations in the venous system of liver are not a rarity. A prospective helical computerized tomography (CT) study was undertaken to determine the prevalence of surgically significant hepatic venous anatomic variations among 100 consecutive living liver donors. The studies evaluated the ramification pattern of hepatic veins, the presence of accessory hepatic veins, and of segment 5 or 8 veins (or both) draining into middle hepatic vein. ⋯ An isolated hepatic vein anomaly or the presence of accessory hepatic veins are not contraindications to be a living liver donor candidate. However, preoperative knowledge of vascular variations alters surgical management. Helical CT is a valuable tool to delineate the hepatic venous anatomy for surgical planning in living liver donors.

Hemodynamic instability has been implicated in the loss of otherwise transplantable organs. We examined the hypothesis that administration of hormonal therapy early during donor management would stabilize hemodynamics and increase the number of organs procured. ⋯ Significantly less adrenergic support was required with early use of CH. A similar (although nonsignificant) reduction was seen with S. The benefit(s) of CH vs corticosteroids alone remains uncertain and requires further study.

Size-reduced lung transplantation: an advanced operative strategy to alleviate donor organ shortage.
The increasing need for donor lungs, especially for small and pediatric recipients, has not been matched by an adequate supply. This disparity has stimulated the development of new operative techniques, which allow downsizing of larger lungs for use in smaller recipients, thus potentially expanding the donor pool. This approach has recently gained more widespread use, especially for highly urgent recipients; however, is still not considered a standard procedure. ⋯ Size-reduced lung transplantations, including split-lung transplantation, lobar transplantation, and peripheral segmental resection, may be considered reliable procedures that provide results comparable to standard lung transplantation. It allows the use of oversized grafts for small and pediatric recipients and the use of single lobes if localized pathologies exist, thus enlarging the donor pool and potentially helping to reduce waiting times and waiting list mortality.
