Subselective diagnostic and interventional arteriography using a simple coaxial catheter system.

Area of Science:

• Vascular Interventional Radiology
• Medical Devices
• Diagnostic Imaging

Background:

• Subselective catheterization is crucial for targeted angiography.
• Minimally invasive techniques are preferred for patient safety and procedural efficiency.

Purpose of the Study:

• To evaluate the safety and efficacy of a coaxial catheter system for subselective angiography.
• To describe the techniques and clinical applications of this catheter system.

Main Methods:

• A 6.5-3.0 French coaxial catheter system was utilized.
• The system was employed for diagnostic and interventional angiography, including drug infusions and embolizations.
• The procedure involved achieving subselective catheter positions.

Main Results:

• The coaxial catheter system was used 81 times in 75 patients.
• No complications were reported during the use of the system.
• Successful subselective catheter positions were achieved for various angiographic procedures.

Conclusions:

• The described coaxial catheter system is a safe and effective tool for subselective angiography.
• This system facilitates both diagnostic and interventional procedures with a low complication rate.
• The technique is versatile and applicable to a range of clinical scenarios.
