A multidisciplinary observational data platform

The ARSIA Project is a structured initiative led by ARSIA to implement a multidisciplinary longitudinal observational study on regenerative surgery.

The ARSIA Project is a structured initiative led by ARSIA to implement a multidisciplinary longitudinal observational study on regenerative surgery.

The project includes the creation of a secure digital registry, the organization of clinical and technical training, and the integration of hospital teams (surgeons, nurses, researchers) within a standardized protocol. With an initial target of 100 documented cases, the project is supported by a young surgeons task force and centralized documentation, aiming for academic recognition through publications and integration into university diplomas.

Autologous Platelet-Rich Plasma for Mediastinitis Prevention: A Randomized Controlled Trial in Isolated CABG Patients

Dr. Gabriel Saiydoun – Prof. Pascal Leprince
Cardiac and Vascular Surgery
La Pitié Salpetrière Hospital – Sorbonne University

Study Objective

To evaluate the efficacy of intraoperative autologous PRP in the prevention of mediastinitis.

Study Design and Population

  • Prospective Study
  • Randomized
  • Controlled
  • Multicenter APHP
  • October 2025 – January 2026
  • Pitié-Salpêtrière University Hospital
  • Coronary Bypass Grafts – Adults – History of Cardiac Surgery: Exclusion

Materials & Methods

Patient Groups

Control Group (Standard Closure):

100 patients – Conventional steel wires – No PRP application

PRP Group:

100 patients – Sternal closure with the same conventional steel wires – With intraoperative application of autologous PRP

Patient Groups

3 types of PRP prepared:

  • RegenPRP™: Prepared using the RegenBCT tube and injected into the scar edges
  • PRP Gel: Prepared using the Surgery Kit and applied to the sternum wound
  • PRP Glue: Prepared using the ACR-C Plus (RegenBCT and RegenATS + Spray applicator) injected

into and onto the wound after suturing

Follow-up and Outcome Criteria

Primary Outcome Criteria: Incidence of mediastinitis and mediastinitis-related mortality

6 months

Secondary Outcomes  independently assessed:

  • Isolated incidence of mediastinitis
  • Mediastinitis-related mortality
  • All-cause mortality
  • Sternal wound dehiscence or instability
  • Length of hospital stay
  • Reoperation rate
  • Occurrence of bleeding complications

Result in June 2026
