Vascular access for therapeutic plasma exchange.

Area of Science:

• Apheresis
• Nephrology
• Hematology

Background:

• Therapeutic plasma exchange (TPE) is an apheresis technique that removes and replaces patient plasma.
• It is utilized for a wide range of diseases, with the 7th edition of American Society for Apheresis guidelines listing approximately 72 diseases and 116 indications.
• Effective TPE necessitates robust vascular access to ensure adequate blood flow for treatment efficacy.

Purpose of the Study:

• To provide a comprehensive overview of therapeutic plasma exchange.
• To detail the clinical diseases and indications treatable with TPE.
• To review various vascular access methods for TPE, including their pros and cons.

Main Methods:

• Review of therapeutic plasma exchange principles and applications.
• Analysis of vascular access options for apheresis procedures.
• Discussion of advantages and disadvantages of different access types.

Main Results:

• Therapeutic plasma exchange is a versatile apheresis treatment with broad clinical applications.
• Vascular access is a critical determinant of successful TPE, requiring high blood flow.
• Available vascular access options include peripheral venous access, arteriovenous grafts/fistulas, and central venous catheters (tunneled or with ports).

Conclusions:

• Therapeutic plasma exchange is a significant treatment modality for a multitude of conditions.
• The choice and management of vascular access are paramount for optimal TPE outcomes.
• Understanding the characteristics and indications of TPE and its associated vascular access is essential for clinicians.
