Ultrasound-guided needle release of A1 pulley combined with corticosteroid injection is more effective than ultrasound-guided needle release alone in the treatment of trigger finger.

Background: The purpose of the present study was to evaluate the clinical effectiveness of ultrasonography-guided needle release of A1 pulley combined with corticosteroid injection by comparing it with ultrasound-guided needle release of the A1 pulley alone.

Methods: A total of 49 patients (55 fingers, thumb) with trigger fingers were included in this retrospective study. Twenty-seven fingers were treated with ultrasound-guided needle release of the A1 pulley alone (monotherapy group), and 28 fingers were treated with needle release of the A1 pulley combined with corticosteroid injection (combination group).

Comparison of the clinical effectiveness of ultrasound-guided corticosteroid injection with and without needle release of the A1 pulley in treating trigger finger.

Objective: To compare the clinical effectiveness of ultrasound-guided corticosteroid injection with and without needle release of the A1 pulley in treating trigger finger.

Methods: A total of 60 patients with trigger finger were enrolled in this retrospective study. Among them, 30 patients were treated with ultrasound-guided needle release of the A1 pulley with corticosteroid injection (group A) and 30 patients were treated with single ultrasound-guided corticosteroids injection (group B).

Feasibility and Reliability of an Ultrasound Examination to Diagnose Piriformis Syndrome.

Objective: We explored the diagnostic performance of ultrasound examinations in the diagnosis of piriformis syndrome (PS).

Methods: In our single-center retrospective study, 52 patients with a diagnosis of PS and 50 healthy volunteers were enrolled to undergo ultrasound examination of the piriformis and sciatic nerve. The thicknesses of the piriformis and the diameter of the sciatic nerve were measured to compare the differences between the patients with PS and healthy volunteers.

Ultrasound-guided needle release of the transverse carpal ligament with and without corticosteroid injection for the treatment of carpal tunnel syndrome.

Background: To compare the clinical effectiveness of ultrasound-guided needle release of the transverse carpal ligament (TCL) with and without corticosteroid injection in carpal tunnel syndrome (CTS).

Methods: From June 2016 to June 2017, 49 CTS patients (50 wrists) were included in this study. Twenty-five wrists were treated with ultrasound-guided needle release of the TCL plus corticosteroid injection (group A), and 25 wrists were treated with single ultrasound-guided needle release of the TCL (group B).

[The methodology and influential factors of real-time elastography in liver examination].

Objective: To investigate the methodology and influential factors of real-time elastography (RTE) in liver examination.

Methods: Forty normal volunteers received the examination of liver with RTE. All strain images were analyzed by the Strain Histogram Measurement and the liver fibrosis index (LFI) values were recorded.

Extrahepatic portal vein aneurysm after orthotopic liver transplantation: a case with 9-year ultrasound observations.

We report a case of extrahepatic portal vein aneurysm (PVA) in the late postoperative period after orthotopic liver transplantation (OLT). A 46-year-old man underwent OLT in 2001 for treatment of hepatitis B virus-induced cirrhosis and received ultrasound follow-up for 9 years. The long-term ultrasound observations showed that the diameter of the main portal vein had progressively increased from 12 mm in 2001 to 34 mm in 2007, and then remained at 34 mm from 2007 to 2010.

[Ultrasound tissue characterization of hepatic fat in rats using radiofrequency signal analysis].

Objective: To investigate the significance of multi-parameter quantitative evaluation of hepatic fat using ultrasound radiofrequency signal analysis.

Methods: Thirty two SD rats were divided into two groups, with 24 having fatty livers and 8 serving as normal controls. Radiofrequency signals were sampled with a 13-MHz ultrasound probe and digitized at 40 MHz in 16-bit resolution.
