Summary
Trans-brachial arterial digital subtraction angiography (DSA) is a viable alternative when trans-femoral access is not possible. This minimally invasive technique effectively visualizes arteries in the limbs, neck, and aorta.
Area of Science:
- Vascular Imaging
- Interventional Radiology
- Diagnostic Angiography
Context:
- Trans-femoral arterial digital subtraction angiography (DSA) is often contraindicated in patients with specific surgical histories or compromised femoral pulses.
- Intravenous DSA may not provide sufficient diagnostic detail due to inherent method limitations.
Purpose:
- To evaluate the efficacy of trans-brachial arterial DSA as an alternative route for angiography.
- To assess the diagnostic quality of trans-brachial DSA in various arterial territories.
Summary:
- Arterial DSA was successfully performed using a 4-French catheter via the trans-brachial route in 33 patients.
- The procedure provided excellent visualization of the abdominal aorta, pelvis, lower limb arteries, neck arteries, and thoracic aorta.
- Trans-brachial DSA proved effective even when trans-femoral access was contraindicated.
Impact:
- Trans-brachial DSA offers a reliable alternative for vascular imaging when standard approaches are not feasible.
- This technique ensures diagnostic adequacy, enabling appropriate clinical management for a broader patient population.
- Expands interventional radiology options for complex vascular cases.
