This randomized controlled trial evaluated the impact of intravascular ultrasound (IVUS) guidance on procedural strategy and patency in patients with lower limb peripheral arterial disease. Among 59 patients, IVUS guidance led to higher primary patency rates (95% vs 80%) and significantly lower reintervention rates for target vessel revascularization (0% vs 18.2%) at a median follow-up of 7 months.
Key findings
- IVUS guidance resulted in changes in therapeutic strategy in 72% of procedures.
- IVUS identified 28.1% significant residual lesions compared to 6.2% with angiography.
- Primary patency was 95% in the IVUS group versus 80% in the control group.
- Reintervention rates were significantly lower in the IVUS group for target vessel revascularization (0% vs 18.2%).
Why it matters
The findings suggest that IVUS guidance can enhance procedural decision-making and improve patency outcomes in complex peripheral arterial disease cases, potentially reducing the need for reinterventions.
