Due to the sharp increase in liver transplant candidates and the subsequent shortage of suitable donor livers, an extension of the current donor criteria is necessary. Simple cold storage, the current standard in organ preservation has proven to be insufficient to preserve extended criteria donor livers. Therefore a renewed interest grew toward alternative methods for liver preservation, such as hypothermic machine perfusion and normothermic machine perfusion. These “new” preservation methods were primarily assessed in rat models, and only a few clinically relevant large animal models have been described so far. This review will elaborate on these alternative preservation methods. Anat Rec, 291:735–740, 2008. © 2008 Wiley‐Liss, Inc. 相似文献

Although a full understanding of the hepatic circulation is one of the keys to successfully perform liver surgery and to elucidate liver pathology, relatively little is known about the functional organization of the liver vasculature. Therefore, we materialized and visualized the human hepatic vasculature at different scales, and performed a morphological analysis by combining vascular corrosion casting with novel micro‐computer tomography (CT) and image analysis techniques. A human liver vascular corrosion cast was obtained by simultaneous resin injection in the hepatic artery (HA) and portal vein (PV). A high resolution (110 μm) micro‐CT scan of the total cast allowed gathering detailed macrovascular data. Subsequently, a mesocirculation sample (starting at generation 5; 88 × 68 × 80 mm³) and a microcirculation sample (terminal vessels including sinusoids; 2.0 × 1.5 × 1.7 mm³) were dissected and imaged at a 71‐μm and 2.6‐μm resolution, respectively. Segmentations and 3D reconstructions allowed quantifying the macro‐ and mesoscale branching topology, and geometrical features of HA, PV and hepatic venous trees up to 13 generations (radii ranging from 13.2 mm to 80 μm; lengths from 74.4 mm to 0.74 mm), as well as microvascular characteristics (mean sinusoidal radius of 6.63 μm). Combining corrosion casting and micro‐CT imaging allows quantifying the branching topology and geometrical features of hepatic trees using a multiscale approach from the macro‐ down to the microcirculation. This may lead to novel insights into liver circulation, such as internal blood flow distributions and anatomical consequences of pathologies (e.g. cirrhosis). 相似文献

Background: We evaluated the concordance between peri-areolar blue dye and peri-incisional radiotracer injections for axillary sentinel node mapping of patients with the history of previous breast lesion excisional biopsy. Methods: 80 patients with the history of previous excisional biopsy of the breast lesions were included. All patients received two injections of 99mTc-antimony sulfide colloid in both ends of incision line in an intradermal fashion. 2 mL patient blue V dye was injection to all patients in the peri-areolar area of the index quadrant after induction of anesthesia. All blue or hot nodes were harvested as sentinel lymph nodes.Results: At least one sentinel node could be detected during surgery in 79 patients. In total 94 sentinel nodes were detected. All detected sentinel nodes were hot. In three patients sentinel nodes were detected by gamma probe but not blue dye. The tumor location in all of these patients was in the upper lateral quadrant and the incision line was extended into the axillary tail of the breast in all of them. 91 out of 94 sentinel nodes were stained blue, which amounts to 95.8% concordance between blue dye and radiotracer on a per node analysis.Conclusions: Single peri-areolar injection in the index quadrant would suffice for sentinel node mapping of patients with history of excisional biopsy. Care should be taken in patients with large excisional biopsy in the extreme proximity to axilla. 相似文献

This study aimed to identify clinical characteristics of impaired trunk control in hundred children with spastic CP (mean age 11.4 ± 2.1 years, range 8–15 years). Assessment of trunk control was performed with the Trunk Control Measurement Scale (TCMS). Trunk control was clearly impaired, indicated by a median total TCMS score of 38.5 out of 58 (66%). Median subscale scores were 18 out of 20 (90%) for the subscale static sitting balance, 16 out of 28 (57%) for the subscale selective movement control and 6 out of 10 (60%) for the subscale dynamic reaching. Total TCMS and subscale scores differed significantly between topographies and severity of motor impairment according to the Gross Motor Function Classification System (GMFCS). Children with hemiplegia obtained the highest scores, followed by children with diplegia and children with quadriplegia obtained the lowest scores. TCMS scores significantly decreased with increasing GMFCS level. In conclusion, trunk control is impaired in children with CP to a various extent, depending on the topography and severity of the motor impairment. The findings of this study also provide specific clues for treatment interventions targeting trunk control to improve their functional abilities. 相似文献

Shortage of liver grafts is the only limiting factor for application of liver transplantation and causes an increasing mortality on the waiting list. Very old donors (>70 to 80 years old) are rarely referred to transplant centers because of the assumption that these livers will not work properly. Alternatively, transplant teams may be reluctant to use these very old livers due to the risk of poor posttransplant outcome. We reviewed our experience with seven liver transplantations using very old donor livers. We found that the results in terms of graft function and patient survival are adequate. Interestingly, the majority of these donors originated from a single referring donor unit (of more than 20 units who belong to our donor network) that systematically refers all brain-dead donors to the transplant center, independent of the age of the potential donor. This implies that many of these donors are left undetected in other units. In conclusion, very old donors should be referred to transplant centers since results of transplantation with these grafts are favorable. 相似文献

Pre‐operative trans‐catheter arterial chemo‐embolization increases hepatic artery thrombosis after liver transplantation – a retrospective study 下载免费PDF全文

Little is known about nonsurgical risk factors for hepatic artery thrombosis (HAT ) after liver transplantation (LT ). We determined risk factors for HAT occurring within 90 days post‐LT and analysed the effect of HAT on graft and patient survival. Donor and recipient demographics, surgery‐related data and outcome in transplants complicated by thrombosis (HAT +) and their matched controls (HAT ?) were compared. Risk factors were assessed by univariate logistic regression. Median (IQR ) is given. A total of 25 HAT occurred among 1035 adult LT (1/1997–12/2014) and 50 controls were manually matched. Donor and recipient demographics were similar. Pre‐LT trans‐catheter arterial chemo‐embolization (TACE ) was more frequent in HAT + (HAT + 20% vs. HAT ? 4%, P = 0.037). HAT + had longer implantation [HAT + 88 min (76–108) vs. HAT ? 77 min (66–93), P = 0.028] and surgery times [HAT + 6.25 h (5.18–7.47) vs. HAT ? 5.25 h (4.33–6.5), P = 0.001]. Early graft dysfunction and sepsis were more frequent in HAT + and hospitalization longer. TACE had the greatest odds ratio in unadjusted analysis (OR : 6, 95% CI : 1.07–33.53, P = 0.03). All but seven grafts were lost after HAT (HAT + 72% vs. HAT ? 36%, P = 0.003); however, patient survival was unaffected (HAT + 79.8% vs. HAT ? 76%, P = 0.75). LT candidates undergoing TACE are at risk of developing HAT early after transplant. 相似文献

The objective of the study is to determine whether evolution in surgical techniques results in minimization of technical graft loss after simultaneous pancreas-kidney transplantation (SPKTx). Eighty consecutive patients with insulin-dependent diabetes mellitus and end-stage nephropathy, and who received SPKTx, were studied. Patient, pancreas and kidney survival at 5 years were 89, 84 and 84% respectively. The porto-systemic venous anastomosis laterally to the arterial vessels resulted in exclusion of technical graft loss due to venous thrombosis. The switch from exocrine bladder drainage to enteric drainage lowered significantly the posttransplant surgical morbidity. This series indicates that excellent short- and long-term survival can be obtained after SPKTx and this with a low perioperative surgical morbidity. 相似文献
