Insights
The side-rail technique simplifies contralateral gate cannulation during endovascular aortic repair, saving time and radiation exposure. This method is now routinely used for most aortic repair procedures.
Area of Science:
- Vascular Surgery
- Endovascular Interventions
- Medical Device Technology
Background:
- Contralateral gate cannulation in endovascular aortic repair (EVAR) can be challenging in complex anatomies.
- Traditional methods may require time-consuming crossover techniques and snare use, increasing procedure duration and radiation exposure.
Purpose of the Study:
- To describe and evaluate the side-rail technique for contralateral gate cannulation in EVAR.
- To assess the time and radiation-sparing benefits of this technique.
Main Methods:
- Detailed description of the side-rail technique, including procedural steps.
- Video material demonstrating the technique's performance.
- Routine application of the technique in EVAR procedures at Helsinki University Hospital since 2016.
Main Results:
- The side-rail technique simplifies contralateral gate cannulation.
- The technique is time-sparing compared to traditional methods.
- The technique is radiation-sparing, reducing patient and staff exposure.
Conclusions:
- The side-rail technique is a simple and effective method for contralateral gate cannulation in EVAR.
- This technique offers significant time and radiation benefits.
- The side-rail technique is suitable for routine use in most EVAR procedures.
Abstract:
In challenging anatomy and large aneurysms, cannulation of the contralateral gate may be time-consuming and sometimes requires crossover approach with a snare. At Helsinki University Hospital, we have since 2016 used the so-called side-rail technique. This technique is described in detail in this paper including video material on the performance of the procedure. We have found this simple technique to be time and radiation sparing, and we now use it routinely in most endovascular aortic repair procedures.
