What is the maximum vessel size recommended for effective coaptive techniques?

The maximum vessel size recommended for effective coaptive techniques is 2 mm. This size is significant because coaptive techniques, often used in endoscopic surgery, rely on the precise alignment and engagement of vascular structures to ensure hemostasis and facilitate successful suturing or clipping.

When the vessel size exceeds 2 mm, achieving an adequate coaptation becomes more challenging, potentially resulting in compromised closure or failure to achieve hemostasis. Smaller vessels are more amenable to these techniques since they can be properly aligned and manipulated without excessive tension, which could lead to tissue damage or inadequate sealing.

In surgical practice, maintaining optimal performance of coaptive techniques is crucial to minimize bleeding and improve patient outcomes, which is why the 2 mm threshold is advised.
