Factors Predicting Fetal Growth Restriction and Fetal Cardiac Remodeling.

Objective: This study aimed to investigate factors influencing fetal growth restriction (FGR) occurrence and assess the clinical significance of fetal cardiac parameters in FGR prediction.

Methods: Pregnant women with clinically suspected FGR (n=179) and uncomplicated pregnancies (n=53) were included. All had undergone routine obstetric ultrasonography and fetal echocardiography.

Mechanism of balloon burst during transcatheter aortic valve replacement pre-dilatation: Image observation and validation by finite element analysis.

Background: Balloon burst during transcatheter aortic valve replacement (TAVR) is serious complication. This study pioneers a novel approach by combining image observation and computer simulation validation to unravel the mechanism of balloon burst in a patient with bicuspid aortic valve (BAV) stenosis.

Method: A new computational model for balloon pre-dilatation was developed by incorporating the element failure criteria according to the Law of Laplace.

Feasibility of Left Bundle Branch Area Pacing Combined with Atrioventricular Node Ablation in Atrial Fibrillation Patients with Heart Failure.

Background: Pacemaker implantation combined with atrioventricular node ablation (AVNA) could be a practical choice for atrial fibrillation (AF) patients with heart failure (HF). Left bundle branch area pacing (LBBaP) has been widely reported.

Objectives: To explore the safety and efficacy of LBBaP combined with AVNA in AF patients with HF.

Features of lymph node metastasis of papillary thyroid carcinoma in ultrasonography and CT and the significance of their combination in the diagnosis and prognosis of lymph node metastasis.

Purpose: To investigate the characteristics of lymph node (LN) metastasis of papillary thyroid carcinoma (PTC) with ultrasonography (US) and spiral computed tomography (CT) and the significance of their combination in the diagnosis and prognosis of LN metastasis.

Methods: A total of 93 PTC patients admitted to and treated in the oncology department of our hospital were randomly enrolled in this study. LN imaging signs were explored by US, CT and their combination.

A dissecting aneurysm of interventricular septum resulting from congenital coronary artery fistula.

Rationale: Ventricular septal dissecting aneurysms are rarely caused by congenital coronary artery fistulas.

Patient Concerns: We present a rare case of ventricular septal dissecting aneurysm that resulted from a congenital coronary artery fistula in a 41-year-old female patient with the complaint of chest pain.

Diagnosis: Ventricular septal dissecting aneurysm resulting from a right coronary artery fistula.

Clinical value of serial ultrasonography in the dynamic observation of foetal cystic adrenal lesions.

Objectives: The objective of the study is to evaluate the diagnostic value of ultrasonography in cystic lesions of the adrenal gland.

Methods: Twenty-two cases of adrenal cystic lesions found in the foetal period were retrospectively analysed. All foetuses were followed up by ultrasound after birth, and all lesions were confirmed by operation or ultrasound-guided biopsy.

Dose-response studies of Ropivacaine in blood flow of upper extremity after supraclavicular block: a double-blind randomized controlled study.

Background: The sympathetic block of upper limb leading to increased blood flow has important clinical implication in microvascular surgery. However, little is known regarding the relationship between concentration of local anesthetic and blood flow of upper limb. The aim of this dose-response study was to determine the ED and ED of ropivacaine in blood flow after supraclavicular block (SB).

Improvement of continuous subcutaneous insulin infusion on patients with type 2 diabetes mellitus by 3-dimensional speckle tracking echocardiography.

Three-dimensional speckle tracking echocardiography (3D-STE) was used to evaluate the improvement of continuous subcutaneous insulin infusion on the left ventricular (LV) systolic function of patients with type 2 diabetes mellitu (T2DM). We recruited T2DM patients (38 cases, diabetic group) and healthy volunteers (35 cases, control group) to collect LV full volume imaging. TomTec software was used for calculating LV global longitudinal strain (LVGLS), global circumferential strain (LVGCS), peak twist (LVTW), peak apical rotation (LVPAR), ejection fraction (LVEF), and torsion (LVT).

The value of ultrasound in the preoperative diagnosis of muscle herniation: A comparison with magnetic resonance imaging.

Objectives: To evaluate the clinic value of ultrasound (US) in the diagnosis of muscle herniation.

Methods: This retrospective study was performed on 26 patients with muscle herniation confirmed by surgery. All patients were examined by US and magnetic resonance imaging (MRI) preoperatively.

[Transabdominal ultrasound measurement of intravesical prostatic protrusion helps diagnosis of benign prostatic obstruction].

Objective: To evaluate the measurement of intravesical prostatic protrusion (IPP) by transabdominal ultrasonography (TAUS) in the diagnosis of benign prostatic obstruction (BPO).

Methods: We studied the clinical data of 109 BPH patients referred for lower urinary tract symptoms (LUTS) from April 2005 to December 2006. IPP was measured by TAUS, urodynamic parameters such as Qmax and PdetQmax obtained by urodynamic studies and AG values calculated.

[Efficacy of axillary approach brachial plexus blocking by ultrasound-guided four points via one-puncture technique].

Objective: To investigate the clinical effects and safety of the technique of axillary approach brachial plexus blocking by ultrasound-guided four points via one-puncture.

Methods: Eighty patients scheduled for elective operation were randomly divided into 2 equal groups to undergo axillary approach brachial plexus blocking by ultrasound-guided four points via one-puncture technique (Group U) or nerve stimulator-guided brachial plexus blocking (Group N). The main branches of brachial plexus (radial, median, ulnar, and musculocutaneous nerves) were localized by ultrasound-guided or nerve stimulator-guided techniques.
