Nine cases (1.5%) had early portal vein complications. By comparing the general status of recipients and donors and the intraoperative findings, the risk factors of early portal vein complications were analyzed. \u0000 \u0000 \u0000Results \u0000No statistically significant differences existed in recipient age, gender, donor/recipient blood type, donor liver cold ischemia time, transplant operative duration, intraoperative non-hepatic period, intraoperative blood loss or intraoperative red blood cell transfusion (P>0.05). However, preoperative recipients had portal vein thrombosis, splenectomy, retransplantation and portal vein anastomosis. Statistical differences existed and all were risk factors for early portal vein complications (P<0.05). Binary logistic regression showed that preoperative patients had portal vein thrombosis [OR=16.922, 95% CI(1.859-154.059), P=0.012] and retransplantation [OR=64.871, 95% CI(8.293-507.435), P<0.001] was an independent risk factor for early portal vein complications. Nine cases of early portal vein complications were confirmed by ultrasound and/or computed tomography (CT) angiography. Three patients with portal vein thrombosis type 1 received oral medication while another three with portal vein thrombosis type 2 underwent abdominal portal vein incision, thrombectomy and large omental portal vein pump implantation. During a follow-up period of (22±14.8) months, portal vein blood flow remained patent. One patient with portal vein stenosis underwent portal vein balloon dilation and stent implantation. During a follow-up period of 17 months, portal vein blood flow remained patent. Two patients with abnormal portal vein blood flow underwent liver re-transplantation and died postoperatively. \u0000 \u0000 \u0000Conclusions \u0000Preoperative portal vein thrombosis and splenectomy, re-transplantation of liver and end-to-end anastomosis of non-donor recipient portal vein are risk factors for early portal vein complications after liver transplantation. Individualized treatments of portal vein thrombosis may be provided according to the type of thrombus and liver function. And the prognosis is decent. Because of a higher mortality rate, attention should be paid to patients with abnormal portal vein blood flow immediately after re-transplantation. \u0000 \u0000 \u0000Key words: \u0000Liver transplantation; Portal complications; Risk factors; Diagnosis; Treatment; Prognosis","PeriodicalId":9885,"journal":{"name":"Chineae Journal of Organ Transplantation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89349535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Risk factor analysis revealed that the incidence of NS complications were 33.3% in Fanconi anemia, 19.2% in myelodysplastic/myeloproliferative neoplasm (MDS/MPN), 7.3% in acute leukemia, 7.0% in aplastic anemia, 3.1% in genetic immunodeficiency disease, none in other disease (P=0.027). The median age of children with NS complications was 9(4.75-12) versus 6(3-10) (P=0.02) those without NS complications. The incidence of NS complications with and without GVHD>2 degree were 24%(6/25) and 6.6%(20/305)(P=0.002).

Methods Orthotopic kidney transplantation was performed in Sprague-Dawley rats (n=6). Pretreatment of hydrogen-rich and conventional water started at 1 week pre-transplantation. Conventional water was provided for both donors and recipients in control (C) group, hydrogen-rich water for recipients and conventional water for donors in hydrogen-water-treated recipient (HWR) group, hydrogen-rich water for donors and common water for recipients in hydrogen-water-treated donor (HWD) group, hydrogen-rich water for both donors and recipients in hydrogen-water-treated donor and recipient (HWDR) group. Renal function, oxidative stress, inflammatory and apoptotic parameters were monitored at 24h post-reperfusion. The phosphorylation of p38 in kidney graft was assayed by Western blot. Results As compared with C group, renal function of recipients became ameliorated in HWR/HWD/HWDR group. Meanwhile, oxidative stress and inflammatory response were mitigated and lessened pathological injury and apoptosis of renal tubular epithelial cells coincided with suppressing apoptosis-related protein's generation and phosphorylation of p38 (P<0.05). Compared with HWR group, the above differences were more significant in HWD and HWDR groups (P<0.05). Conclusions Preoperative intake of hydrogen water attenuates renal I/R injury after kidney transplantation. And suppressing the activation of p38 MAPK may be a potential mechanism.

The recipients of ECD donor kidneys not evaluated for kidney zero puncture assessment from January 2014 to July 2016 were group A1 and those receiving standard donor kidney (SCD) belonged to group A2. From August 2016 to March 2019, all DCD donors were routinely evaluated for kidney zero puncture and those receiving ECD recipients fell into Group B1 and those receiving SCD belonged to Group B2. Analysis was performed for ECD/SCD donor renal zero puncture pathological features and lesion degree and utilization of ECD donor kidney; donor-recipient body surface area (BSA) ratio and lesion degree of ECD donor kidney on recipient selecting and matching. Serum creatinine value, perioperative adverse events and 1-year follow-up of human/kidney survival rate in each group were compared at 1 day, 1 week, 1 month, 3 months, 6 months and 1 year. \u0000 \u0000 \u0000Results \u0000A total of 108, 264, 306 and 416 recipients were recruited into A1, A2, B1 and B2 groups respectively.

According to the 2016 Banff standard, glomerular sclerosis (GS), renal interstitial fibrosis (Ci) and intimal fibrosis thickening (Cv), small arterial intimal hyalinization (ah), tubular atrophy (ct) and acute tubular injury (ati) accounted for more than B1 group than B2 group (P<0.05).

After 1 year, serum creatinine value of B1 group was lower than that of A1 group (P<0.05). \u0000 \u0000 \u0000Conclusions \u0000The quality of ECD donor kidney is obviously inferior to that of SCD donor kidney. The Banff donor kidney criterion is an effective mode of evaluating the quality of ECD donor kidney. Based upon the extent of Banff's nephropathy, the ratio of donor/recipient BSA is an important selecting method for ECD donors to receive kidneys and recipients, ultimately improving graft utilization and recipient transplantation. \u0000 \u0000 \u0000Key words: \u0000Kidney transplantation; Renal needle biopsy; Body surface area","PeriodicalId":9885,"journal":{"name":"Chineae Journal of Organ Transplantation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83287031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
