Introduction: The vascular condition influences the outcomes of arteriovenous fistula (AVF) surgery. However, it has not been established how it influences the outcomes of renal transplantation and the development of chronic allograft nephropathy (CAN). The aim of this study was to define the relationship between AVF failure in the pretransplant period and the development of CAN.
Patients And Methods: In this study we included all patients who underwent AVF surgery and then first kidney allotransplantations from January 1, 1999 to December 31, 2002. Patients were divided into two groups according to the AVF surgery outcomes: group 1 (n = 45, mean age 50 +/- 13 years, male/female ratio 27/18) had no vascular access complications and were dialysed through a native AVF. Group 2 (n = 39, mean age 51 +/- 11 years, male/female ratio 17/22) had additional interventions due to AVF failure. We analyzed the incidence of CAN in both groups.
Results: During the follow-up period CAN was observed in five patients in group 1 and 11 patients in group 2 (11,1% vs 28,2%, P < .05). There was a statistically significant relationship between CAN and acute rejection episodes (P < .005) and diabetes mellitus (P < .05).
Conclusion: Failures of arteriovenous fistulas in hemodialysis patients were associated with an increased incidence of CAN in the posttransplant period.

Introduction: Arterialized venous flap, like any other flap, will undergo an ischemic reperfusion injury during its transfer process. To overcome this, ischemic preconditioning can be done to provide protection and enhanced flap survival. One of the reliable parameters of flap survival is its temperature.

Approximately 22 % of the United States population communicates in a non-English language, potentially impacting healthcare communication and outcomes. Few studies have examined the association between non-English primary language (NEPL) and surgical outcomes and none to our knowledge in patients undergoing arteriovenous fistula creation within a safety net system. In this study, we conducted a retrospective analysis on adults who underwent AVF creation for hemodialysis access between January 1, 2014, and December 31, 2019.

Arteriovenous grafts (AVG) can be the only bailout solution for patients who require kidney replacement therapy but are unsuitable for arteriovenous fistula (AVF) creation. Currently, high-level evidence on the effectiveness and safety of antithrombotic therapy in AVG patients is scarce. Following the PICO (patient; intervention; comparator; outcome) model and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, a data search of the English literature in PubMed, SCOPUS, Central Cochrane was conducted, until March 1st, 2023 (PROSPERO Protocol Number: CRD42023401785).

Objectives: This study evaluates and compares outcomes of arteriovenous fistulas (AVFs) created in a dialysis access dedicated office-based laboratory (OBL) and outpatient hospital setting.
Methods: All consecutive outpatient surgical autologous AVFs created at an academic hospital, community hospital, and an OBL from 2016-2020 were reviewed. Demographics, comorbidities, surgical procedure, complications, maturation, patency, and procedures for maintenance were assessed from time of surgical evaluation to latest available documentation.
