Spiral spring effect in catheters as a complicating factor of femorocerebral catheterization
Insights
Selective femorocerebral catheterization can cause iatrogenic embolization of atherosclerotic material. This complication, linked to catheter manipulation and size, can be avoided with proper technique and catheter selection.
Area of Science:
- Neurology
- Vascular Surgery
- Interventional Radiology
Background:
- Selective femorocerebral catheterization is a key diagnostic and therapeutic procedure.
- Atherosclerotic embolization is a known risk in vascular interventions.
Observation:
- A complication occurred during selective femorocereocerebral catheterization.
- The complication involved iatrogenic embolization of atherosclerotic material from the common carotid artery bifurcation.
Findings:
- The complication resulted from incorrect catheter manipulation.
- Improper selection of catheter dimensions relative to the aortic arch diameter was a contributing factor.
- The specific catheter type (Sidewinder, Cordis Corporation) and its shape influenced the maneuvers.
Implications:
- Recommendations are provided to prevent this complication.
- Improved catheter manipulation techniques are crucial.
- Appropriate catheter sizing is essential for patient safety during femorocerebral angiography.
Abstract:
This paper describes a complication of selective femorocerebral catheterization which was due to iatrogenic embolization of atherosclerotic material originating from the bifurcation of the common carotid artery. After analysis of the catheter maneuvers inherent to the special shape of the type of catheter used (Sidewinder, Cordis Corporation), it is concluded that this complication resulted from incorrect catheter manipulation and an incorrect choice of the dimensions of the preshaped part of the catheter in relation to the diameter of the aortic arch. Two recommendations to avoid this complication are made.
