FAQ

Why choose a stent?​

The placement of this type of laryngeal or tracheal prosthesis is a short, minimally invasive, atraumatic and simple implantation procedure. In many cases it can be a therapeutic alternative to avoid surgery, for example for laryngeal paralysis in elderly dogs to improve their quality of life.

When is it advisable to place a silicone stent?

  • laryngeal stenosis
  • tracheal collapse
  • laryngeal paralysis
  • smooth surface tumour
  • squamous cell carcinoma
  • paroxysmal form of dyspnoea attacks

Why are there so many models of stents?

Because each veterinarian must choose the device that best suits his or her patient’s case.

How do you know the right stent diameter?

The choice of prosthesis diameter would be based on the endotracheal tube that the professional places and we suggest estimating 20% more.

This measure would be based on the choice of the largest endotracheal tube. It is very common to underestimate the diameter of the tube to be used, so it is advisable to have several diameters available at the time of the intervention.

Also, it should be considered that being a minimally invasive procedure makes the prosthesis removable without damage, so if a diameter error is made, it can be easily changed.

A simple way to estimate the approximate diameter is to measure the animal’s muzzle, as shown in the photo:

Can anyone place a stent?

No, it is not possible. Stent insertion needs to be performed by trained personnel and specialists.

What happens when the stent is placed?

Our stents are inserted folded and self-expand when released in the affected area. As they expand, they provide more light, allowing air to circulate inside them. In some cases the practitioner may decide to place a few stitches to secure the stent in place.

Is fluoroscopy essential for stent insertion?

No, it is not required. Normally, inserting the stent by clamping it with a forceps is sufficient. Each professional has his or her own technique, but in veterinary medicine in particular, stent insertion is much simpler than in humans.

What material is the stent made of?

All our devices are made of medical grade silicone. They can be transparent in case the veterinarian wishes to visualise the tissues through the device, or radiopaque in case he/she wishes to perform radiographic controls.

We are an ISO13485/2016 certified company (medical device manufacturing) and apply the same quality standards to the manufacture of our entire veterinary line.

How often is a stent changed?

It is advisable to do this every three months. But the final decision is at the discretion of each professional and the evolution of the patient.
