Summary
The transradial route for arteriography offers a safe and effective alternative to traditional methods, demonstrating a low complication rate. This technique is suitable for outpatient peripheral angiography, especially for high-risk patients.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Cardiovascular Imaging
Background:
- Traditional arteriography often utilizes transfemoral or brachial approaches.
- These methods carry potential risks, particularly in patients with bleeding predispositions.
- The transradial approach is increasingly explored for vascular interventions.
Purpose of the Study:
- To evaluate the efficacy and safety of the transradial route for arteriography.
- To assess the feasibility of this approach for outpatient peripheral angiography.
- To compare complication rates with conventional arteriography methods.
Main Methods:
- Seventy-five arteriographies were performed using a 5F, 130cm catheter via the transradial route.
- Radial artery patency was confirmed using the Allen test prior to puncture.
- Imaging included the thoracic aorta, carotid arteries, infrarenal aorta, and pelvic/leg arteries.
Main Results:
- High-quality imaging was achieved for all targeted arterial segments.
- The transradial approach demonstrated a very low rate of complications.
- Technical failure rates were also minimal, indicating high procedural success.
Conclusions:
- The transradial route is a viable and safe alternative for arteriography.
- It is particularly advantageous for outpatient peripheral angiography.
- This method is recommended for patients with high hemorrhagic risk or when transfemoral access is not feasible.
