Which imaging-guided technique is used to guide treatment of a pseudoaneurysm?

• A. Doppler guided compression
• B. CT angiography without guidance
• C. X-ray guided repair
• D. MRI guided therapy

Answer: (A)

Real-time ultrasound guidance enables a noninvasive, targeted approach to treating a pseudoaneurysm by applying compression across the neck while watching the flow in and out of the sac. Duplex Doppler lets you see the pseudoaneurysm sac and the connecting channel, so you can guide manual or sustained compression until the flow ceases and thrombosis occurs. This method is favored because it provides immediate feedback, is radiation-free, and can be done at the bedside without invasive procedures. Other imaging methods listed are not used to guide this therapeutic compression in real time: CT angiography without guidance is diagnostic imaging, not a live treatment guide; X-ray guided repair would rely on fluoroscopy for an intervention but isn’t the standard first-line technique for compressive therapy; MRI guidance isn’t a practical or common approach for this treatment.
