🧠 SONOBIRDIE Trial: A Sonic Breakthrough in Carotid Endarterectomy Safety 🎯

A wave of innovation is echoing through vascular surgery — and it sounds like ultrasound. The SONOBIRDIE trial, published in BMJ, brings fresh promise for patients undergoing carotid endarterectomy. By adding sonolysis, a low-intensity ultrasound technique, during surgery, the trial reveals significantly lower rates of neurological complications. This could redefine safety standards for patients with carotid stenosis. 🩺🧬

🌍 Study Overview

The multicenter trial involved 1,004 patients across Czechia, Slovakia, and Austria, all with ≥70% symptomatic or asymptomatic internal carotid artery stenosis.

🔍 Key Findings at a Glance

✨ 5.5% absolute reduction in the combined rate of ischemic stroke, TIA, or death within 30 days of surgery (2.2% vs 7.6%)
🧠 Lower risks of both ischemic stroke (RR 0.25) and TIA (RR 0.23) in the sonolysis group
🧲 Fewer new ischemic lesions on brain MRI 24 hours post-op (8.5% vs 17.4%)

These aren’t just numbers — they’re lives potentially changed and brains protected. 🧠💪

🛡️ Safety Profile: Rock Solid

📈 94.4% of patients in the sonolysis group remained free from serious adverse events
🩸 Only one case of intracerebral bleeding was reported in the entire trial

This shows that sonolysis isn’t just effective — it’s safe, too. ✅

🌀 How Sonolysis Works

Sonolysis uses a low-intensity pulsed wave ultrasound beam, applied via a transcranial Doppler probe — the same kind used in many hospitals today.

🛠️ Mechanism of Action:

• Activates fibrinolytic enzymes

• Disrupts microemboli and existing clots

• Non-invasive, continuous application during surgery

Implementation is simple — if you’ve got an ultrasound machine, you’re halfway there! ⚙️🖥️
