Establishment of a scoring system for predicting the difficulty level of high-intensity focussed ultrasound ablation of uterine fibroids

Abstract

A scoring system for predicting the difficulty level of HIFU treatment for uterine fibroids has been established and it can be used to help select patients and to predict the sonication time for a given fibroid.

Adverse effect analysis of high-intensity focused ultrasound in the treatment of benign uterine diseases

“…In this study, a median NPV ratio of 85% was achieved in uterine fibroids, 72% in adenomyosis. The NPV ratios are similar to the previous studies [4,[10][11][12][13]. Patients with cesarean scar pregnancy or placenta accreta had suction curettage under hysteroscopic or ultrasound guidance after HIFU; the procedure was successful.…”

A retrospective study of ultrasound-guided high intensity focussed ultrasound ablation for multiple uterine fibroids in South Africa

“…Over the last decade, high intensity focussed ultrasound (HIFU) has been widely used in clinical practice to treat uterine fibroids. As a non-invasive treatment technique, HIFU is performed under the guidance of ultrasound or magnetic resonance imaging, so the fibroids can be selectively ablated, even fibroids smaller than 2 cm in diameter, without damaging adjacent structures [10,11]. Many studies from Asia, Europe and North America have demonstrated that HIFU is a safe and cost-effective alternative for the treatment of uterine fibroids [12][13][14].…”

Efficacy and safety of high-intensity focused ultrasound ablation for hepatocellular carcinoma by changing the acoustic environment: microbubble contrast agent (SonoVue) and transcatheter arterial chemoembolization

“…Regarding EEF, previous study demonstrated that the EEF negatively correlated with tumor diameter [17]. In the present study, tumor diameter was not included, attributing to the narrow range (d 5 cm).…”

“…EEF ¼ g Á Pt/V (J/mm 3 ). g is focus coefficient (¼ 0.7); P is sonication power (W); t is HIFU sonication time (s); V is NPV (mm 3 ) [17]. The correlation between EEF and influencing factors, including distance from the deepest layer of the lesion to the hepatic capsule, distance from the deepest layer of the lesion to the abdominal wall, blood supply and iodized oil deposition, was analyzed by statistical methods.…”
