Abstract
We report a case of a 40 year old man with portal hypertension caused by a splenic arteriovenous fistula that was diagnosed at laparotomy. He presented with bleeding esophageal varices and was initially treated by sclerotherapy. At laparotomy, portal pressure was 40 cmH20 but fell to 20 cm H20 after the fistula was treated with splenectomy. All symptoms disappeared shortly after operation and the patient has remained well for the past two years.

Abstract

  Background: Arteriovenous Fistula (AVF)is the ideal method of vascular access for patients on maintenance hemodialysis (HD).Therefore it is an important part of treatment in HD.There are several observations that indicate the role of inflammation in failure of AVF.The aim of this study was to evaluate the hematologic and inflammatory biomarkers in early AVF failure.

  Methods : This case-control study included 110 ESRD patients,whom were undergone AVF creation, divided in two groups. About 700 radius-cephalic AVF were created during these two years. We found 55 cases with AVF failure. In this study, we compared those 55failures with 55 functional AVF which were selected using randomized sampling from the rest of patients according to age, gender, and AVF location.Levels of serum C-reactive protein (CRP) were checked in both groups to evaluate the relation between AVF failure and CRP level before surgery.

  Results : The mean±SD age of the patients was 49.7±17.28years. CRP was positive in 34 patients (61.8%)with unsuccessful fistula function,while only 4 (7.3%)of those with successful AVF had positive CRP and the resthad negative CRP.The difference between the two groups of patients was strongly significant (p<0.001). Statistically, there was not any significant difference between the average of age (p: 0.580) of patients in the control and experimental groups. However, the gender (p: 0.832) discrepancies was not meaningful between the groups.

  Conclusion :AVF thrombosis is one of the main complications after AVF creation.Therefore,it is recommended to check CRP before AVF surgery to prevent possible failure of the fistulafunction.

Abstract
    Background: The survival of arteriovenous fistula (AVF) remains an important problem for hemodialysis patients, accounting for 20% of all hospitalizations related to AV access problems in western countries. We designed an observational prospective cohort study on 265 AVFs and evaluated their results after 4 months of fistula creation and its relation to laboratory tests as ESR and CRP levels.
   Methods: Wrist or antecubital AVFs  were created for patients with End-Stage renal disease. All laboratory tests (ESR and CRP) were checked quantitatively. The patients were followed-upfor at least 4 months and failure or maturation of AVFs were recorded in a checklist.
   Results: 177 (66.8%) males and 88 (33.2%) females were included. The surgeon created 161(60.8%) wrist and 98 (37%) antecubital AVFs. The mean age of patients was 53.18±17.1, ranged from 8 to 91 years old. CRP and total protein had significant differences between the two groups of failure and mature accesses (0.029 and 0.045 respectively).
   Conclusion:  High CRP level is recognized as a reliable predictor for the survival of AVF.
