Summary
Digital subtraction angiography (DSA) effectively visualizes upper extremity arteries, including hands and fingers, with improved ease and safety. This technique largely replaces conventional catheter angiography for these vascular examinations.
Area of Science:
- Vascular imaging
- Radiology
- Interventional cardiology
Background:
- Conventional catheter angiography has limitations in visualizing upper extremity vasculature.
- Digital subtraction angiography (DSA) offers potential advantages for vascular imaging.
Purpose of the Study:
- To evaluate the efficacy of DSA for imaging the arteries of the upper extremities.
- To determine optimal contrast administration for hand and finger artery visualization using DSA.
Main Methods:
- Review of 1500 digital subtraction angiograms, with focus on 93 upper extremity examinations.
- Intravenous contrast injection for subclavian, axillary, brachial, radial, and ulnar arteries.
- Intra-arterial contrast injection (5 ml) into the brachial artery for hand and finger arteries.
Main Results:
- DSA provided excellent visualization of major upper extremity arteries (subclavian to ulnar).
- Intra-arterial contrast injection facilitated detailed imaging of hand and finger arteries.
- DSA procedures were noted to be easier, quicker, and safer than conventional angiography.
Conclusions:
- DSA is a highly effective imaging modality for the arteries of the upper extremities.
- Specific contrast techniques enhance DSA's utility for distal upper limb vasculature.
- DSA significantly reduces the need for conventional catheter angiography in this region.
