Ultrasound thrombolysis.

Area of Science:

• Biomedical Engineering
• Cardiovascular Research
• Medical Physics

Background:

• Ultrasound's potential for thrombolysis was recognized in 1976.
• Early studies demonstrated clot disruption using low-frequency ultrasound via a rigid wire.
• Research has explored four main approaches to ultrasonic thrombolysis.

Purpose of the Study:

• To review recent data on therapeutic ultrasound for thrombolysis.
• To cover in vitro, in vivo, animal, and human clinical trial findings.
• To synthesize the current state of ultrasonic thrombolysis research.

Main Methods:

• Review of existing literature and clinical trial data.
• Analysis of studies employing various ultrasonic thrombolysis techniques.
• Inclusion of both drug-free and drug-assisted ultrasound methods.

Main Results:

• Ultrasound has shown potential for peripheral arterial clot dissolution.
• Different ultrasonic approaches include catheter-delivered and transcutaneous methods.
• Concomitant use with thrombolytic drugs and microbubbles enhances efficacy.

Conclusions:

• Therapeutic ultrasound is a developing field for treating blood clots.
• Multiple strategies exist, with ongoing research in various settings.
• Recent data supports the continued investigation and application of ultrasonic thrombolysis.
