Abstract:

In the past two decades, as a probe-free, non-ionizing radiation minimally invasive thermal ablation technology, high intensity focused ultrasound(HIFU) has developed rapidly. It can focus ultrasound waves on a single point and produce instantaneous high temperature to achieve the therapeutic purpose of thermal degeneration, coagulative necrosis, and apoptosis of target tissue. HIFU can be divided into two categories: ultrasound-guided and magnetic resonance-guided. Among them, ultrasound-guided HIFU is more widely used. It has obtained a large amount of evidence-based data and clinical experience in the treatment of gynecological and obstetric diseases such as uterine fibroids, uterine adenomyosis, cesarean scar pregnancy, postpartum placenta accreta spectrum, and cervical pregnancy, confirming its safety and effectiveness. It can even replace some traditional treatment methods in the treatment of certain diseases. However, ultrasound-guided HIFU is more commonly used in patients with stable conditions, and surgical intervention is often required for the rescue of critical and severe cases. Correct understanding and master of its indications and contraindications are necessary for precise treatment to benefit patients.
