Balloon-assisted over-the-wire technique for placement of the venous outflow component of the Hemodialysis Reliable Outflow (HeRO) device
A modified technique for placement of the venous outflow component (VOC) of the Hemodialysis Reliable Outflow (HeRO) device (Hemosphere Inc, Minneapolis, Minn) is described. The purpose of the technique is to improve the system's trackability and facilitate device insertion in patients with central venous occlusion. Device preparation requires placement of a 6-mm × 4-cm angioplasty balloon within the leading end of the VOC. The leading 2 cm of the balloon are placed just distal to the radiopaque marker of the VOC. The balloon is inflated to profile and locked in this position within the leading end of the VOC. The VOC and balloon combination is advanced over the wire through the 20F peel-away sheath provided by the manufacturer. The described technique was used to successfully implant the HeRO device in 12 patients with central venous occlusion. This technique is recommended for placement of the VOC of the HeRO device in patients with central venous occlusions

No difference in clinical transplant outcomes for local and imported liver allografts
In the United States, liver allograft allocation is strictly regulated. Local centers have the first option to accept a donor liver; this is followed by regional allocation for those donor livers not used locally and then by national allocation for those donor livers not accepted regionally. This study reviews the outcomes of all liver allografts used over 6 years (2001‐2007) and evaluates initial and long‐term function stratified by the geographic source of the donor liver allograft. The records for 845 consecutive deceased donor liver transplants at a single center were reviewed. The geographic origin of the allograft was recorded along with donor and graft characteristics to determine the probable reason for graft refusal. Within our local organ procurement organization, there is 1 liver transplant center, and within the region, there are 8 active centers. Early graft failure included any graft loss within 7 days of transplant, and initial function was measured with liver enzymes 30 days post‐transplant. Graft survival and patient survival were evaluated with Kaplan‐Meier and Cox survival modeling. Median follow‐up was 43 months. The geographic distribution of organs included local organs (562, 66%), regionally imported organs (126, 15%), and nationally imported organs (157, 19%). There were no differences between the 3 groups in initial graft function, intraoperative death, or early graft loss. Survival curves for the 3 study groups demonstrated no difference in survival up to 5 years post‐transplant. In conclusion, liver allografts rejected for use by a large number of transplant centers can still be successfully used without early graft function or long‐term survival being affected.
