C Stamatopoulos, E Biemer, W Stock

    The Journal of Cardiovascular Surgery
    |March 1, 1982
    PubMed
    Summary

    A novel two-suture technique for microvessel anastomosis was developed and tested in rats. This method shows promising results for connecting blood vessels, simplifying surgical procedures.

    Area of Science:

    • Vascular Surgery
    • Microsurgery
    • Surgical Techniques

    Background:

    • Microvascular anastomosis is crucial for reconstructive surgery.
    • Existing techniques can be complex and time-consuming.
    • A simpler, effective method is needed.

    Purpose of the Study:

    • To describe and evaluate a novel two-suture end-to-end anastomosis technique for microvessels.
    • To assess the patency and integrity of microvascular anastomoses created using this method.

    Main Methods:

    • A two-suture end-to-end anastomosis technique was applied to the common carotid artery and femoral vein in 37 rats.
    • Vessel adventitia preparation and saline irrigation were performed.
    • 10-0 Nylon monofil sutures were used with a specific ligation technique.

  • Anastomoses were evaluated after 5 months using surgical microscopy, scanning electron microscopy (SEM), and histology.

    • Main Results:

    • The described two-suture technique facilitates end-to-end anastomosis of microvessels.
    • Post-operative examination revealed successful vessel connection.
    • SEM and histological analyses demonstrated the integrity and patency of the anastomoses.

    Conclusions:

    • The novel two-suture technique is a viable and effective method for microvessel anastomosis.
    • This technique simplifies microsurgical procedures, potentially reducing operative time and complexity.
    • Further studies may explore its application in diverse clinical scenarios.
