Summary
Direct needle arteriography effectively visualizes "pulseless" femoral arteries, even with collateral filling. This technique provides excellent arterial detail for evaluating occluded bypass grafts.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Interventional Radiology
Background:
- Femoral artery access is crucial for lower limb revascularization.
- Challenges exist in visualizing "pulseless" or severely diseased femoral arteries.
