A systematic approach and team effort are crucial for managing vascular access problems. Optimizing planning, maintenance, and early recognition of issues can reduce access thrombosis and failure rates.

Area of Science:

  • Nephrology
  • Vascular Surgery
  • Vascular Access Management

Background:

  • High rates of vascular access thrombosis and failure necessitate improved management strategies.
  • Autogenous arteriovenous (AV) fistulae are preferred over synthetic grafts due to lower complication rates.
  • Early fistula failure remains a significant challenge, limiting the benefits of increased fistula creation.

Purpose of the Study:

  • To emphasize the importance of a systematic approach in managing vascular access.
  • To discuss the role of anatomical knowledge and physical examination in optimizing access.
  • To evaluate the effectiveness of current surveillance methods and the need for evidence-based recommendations.

Main Methods:

  • Review of current literature on vascular access management and surveillance.

  • Discussion of the benefits and limitations of autogenous AV fistulae versus synthetic grafts.
  • Analysis of graft surveillance programs, particularly graft blood flow (Q(a)) monitoring.

    • Main Results:

    • Graft blood flow (Q(a)) surveillance shows poor accuracy in predicting thrombosis.
    • Existing studies on Q(a) surveillance are often retrospective or nonrandomized, hindering evidence-based recommendations.
    • A team approach with organized planning and prompt treatment of access problems is vital for access survival.

    Conclusions:

    • Definitive, evidence-based recommendations for Q(a) surveillance are currently not possible.
    • Reducing early fistula failure is essential to realize the benefits of AV fistula creation.
    • A multidisciplinary team approach focused on planning, recognition, and treatment is key to improving vascular access survival.
