| 4 | Ultrasonographic findings at the resected area after hepatectomy显示文摘BACKGROUND: Since hepatectomy has been widely performed, different operative manner, operating areas, and material in the residual cavity may be found ultrasonographi-cally near the resected area after the operation. In this study, we investigated the changes of focal ultrasonography at the resected area post hepatectomy and recognized the characteristic ultrasonographic images. METHODS: 176 patients whose ultrasonographic findings were studied in the residual area during the early and later periods after hepatectomy were retrospectively analyzed in terms of operative manner, operative area, and material in the residual cavity. RESULTS: There were absence of partial hepatic lobe or hepatic segment, focal anechoic area with thin wall or mixed mass at the resected area, and conformation of irregular high-echoic conglomeration at the resected area, cystic non-anechoic area, and mixed mass with irregularly thickened wall at the resected area, inconsistent internal echoes,and color Doppler twinking artifacts around the material and the residual cavity after curettage and aspiration. CONCLUSIONS: Focal ultrasonographic findings at the resected area after hepatectomy vary with different operative procedures, operative area, resection size, absence or existence of material, and kinds of material in the residual cavity. | Guo-Qiang Mo and Xue-Ming Liu Department of Ultrasound, Second Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310009, China | 2006 | Hepatobiliary & Pancreatic Diseases International2006，5，3： | 1 |
| 5 | 彩色多普勒超声评价肝移植术后急性排异反应显示文摘急性排异反应(acute rejection,AR)是原位肝移植术后最常见并发症。约50%左右的患者表现出临床症状,但临床表现不典型,目前诊断主要依靠病理学检查。彩色多普勒血流显像(CDFI)是监测肝移植术后并发症的常用方法。本研究采用CDFI评价经肝穿活检病理证实的肝移植术后急性排异反应肝血流改变,并与非排异反应患者比较,旨在探讨CDFI评价肝移植术后急性排异反应的应用价值。 | 吕素琴 郑荣琴 任杰 毛永江 张波 黄冬梅 | 2008 | 中华超声影像学杂志2008，17，1： | 1 |
| 6 | 彩色多普勒技术对肝移植大鼠急性排斥反应监测的研究显示文摘[目的]应用彩色多普勒血流成像(color doppler flowimaging,CDFI)技术观察原位肝移植(orthotopic liver trans-plantationo,OLT)后大鼠肝脏的血流情况,并与病理损害对照,探讨CDFI与大鼠肝移植后排斥反应的可行性。[方法]正常组:Wistar大鼠8只。建立OLT模型,将动物分为4组,每组SD大鼠、Wistar大鼠各8只。对照组:未予药物干预;CsA组:给予环孢素A30 mg.kg-1.d-1,胃内给药;SIN组:给予青藤碱40 mg.kg-1.d-1,胃内给药;CsA+SIN组:给予青藤碱40 mg.kg-1.d-1+环孢素A15 mg.kg-1.d-1,胃内给药。术后4天、10天CDFI测量肝脏门静脉、下腔静脉的血流速度,术后10天处死大鼠取肝脏组织行病理检查。[结果]门静脉血流速度:术后4天对照组明显低于各手术组,CsA组与SIN+CsA组明显增快,SIN组轻度增快。术后10天血流速度普遍下降(P<0.05)。CsA组与SIN+CsA组仍快于正常组(P<0.05),SIN组与正常组差异无显著性意义(P>0.05)。动物模型组内肝脏病理损害与门静脉血流速度呈负相关关系(r=-0.776,P<0.01)。[结论]彩色多普勒技术可作为监测大鼠肝移植术后是否有排斥反应发生的一种有效手段,门静脉血流速度的降低提示移植肝脏可能发生了排斥反应。 | 蔡振刚 刘晓黎 高晓军 宋涛 王忠裕 | 2009 | 大连医科大学学报2009，31，6： | 1 |
| 7 | Changes of duplex parameters and splenic size in liver transplant recipients during a long period of observation显示文摘AIM: To assess the changes of portal and arterial velocities, resistance index, spleen and liver size during a long observation period (13.7 years) after orthotopic liver transplantation (OLT).METHODS: Two hundred and sixty patients were recruited retrospectively for this study and divided into groups with defined time intervals after OLT. The cross-sectional changes of portal and arterial velocities,resistance index, spleen and liver size between the defined time intervals were studied. The complications detected by ultrasound were compared to gold standard methods.RESULTS: The mean values for liver size were all within the normal range. The splenic size decreased between the time intervals 100 and 1 000 d after OLT (t;P<0.01).While portal and arterial flow velocities decreased up to 5.5 years (t; portal velocity P<0.01, maximal systolic velocity P=0.05, maximal end diastolic velocity P<0.01),RI increased during this interval (t:P<0.01). Higher RIvalues were found in older patients (r = 0.24, P<0.001).CONCLUSION: The arterial and portal velocities show adaptation processes continuing over the course of many years after OLT and are reported for the first time. The vascular complications detected by ultrasound occur mostly up to 100 d after OLT. | Bita Boozari Michael Gebel Mathias J Bahr Michael P Manns Christian P Strassburg Joerg S Bleck J Klempnauer Bjoern Nashan | 2005 | World Journal of Gastroenterology2005，11，43： | 0 |
