Dynamic ultrasound-guided short-axis needle tip navigation is a novel technique for vascular access. After venipuncture, the needle and catheter are further advanced within the vessel lumen under real-time ultrasound guidance with constant visualisation of the needle tip in the short-axis view. This can minimise the risk of transfixing the cannulated vessel. We compared two techniques for non-visible saphenous vein cannulation under general anaesthesia in children weighing ≥ 3 kg and less than four years of age: dynamic ultrasound-guided short-axis needle tip navigation technique (ultrasound group) vs...

Cytology by fine-needle cytology is indispensable for diagnosing head and neck tumor, especially for thyroid nodule. There are two methods of fine needle cytology; one of fine-needle aspiration cytology (FNAC and another of fine-needle non-aspiration cytology (FNNAC). These previous procedures has each disadvantage such as the mixing of blood or low yield of cells. We proposed a new technique: selective low-pressure fine needle aspiration cytology (SLOP-FNAC) to overcome the backwards of previous procedures...

Ultrasound imaging is widely used for guiding minimally invasive procedures, including fetal surgery. Visualisation of medical devices such as medical needles is critically important and it remains challenging in many clinical contexts. During in-plane insertions, a needle can have poor visibility at steep insertion angles and at large insertion depths. During out-of-plane insertions, the needle tip can have a similar ultrasonic appearance to the needle shaft when it intersects with the ultrasound imaging plane...

BACKGROUND: The cluster approach for supraclavicular brachial plexus block (SC-BPB) can be easily performed but may result in asymmetric local anesthetic (LA) spread. The authors hypothesized that the use of a cluster approach in each of the 2 planes would achieve better 3-dimensional LA distribution than the traditional single cluster approach. OBJECTIVES: The purpose of the present study was to compare a double injection (DI) in 2 planes (one injection in each plane) with the traditional single injection (SI) cluster approach for ultrasound-guided SC-BPB...

INTRODUCTION: Steroid and local anaesthetic injection to the acromioclavicular joint (ACJ) is a very common diagnostic and therapeutic procedure, which is often performed in the outpatient department. However, it can be difficult to localize this joint because of its small size, presence of osteophytes and variable morphology in the population. We performed a study to determine whether the use of an image intensifier (X-ray guidance), in theatre, improves the accuracy of this injection...

Recent advances in interventional pulmonology led to a significant expansion of the diagnostic and therapeutic role of endobronchial ultrasound. In this paper, we describe a new concept for using endobronchial ultrasound to guide interstitial photodynamic therapy (PDT). For this purpose, we conducted in vitro and in vivo experiments using a phantom and animal models, respectively. A new 0.5 mm optical fiber, with cylindrical diffuser end, was used to deliver the therapeutic light through the 21-gauge endobronchial ultrasound needle...

Lung cancer is one of the most fatal cancers in the world. To early distinguish benign and malignant pulmonary nodule is critical for disease prognosis. Confocal laser endomicroscopy (CLE) can be used to explore bronchus mucous membrane, alveolar elastic fiber structures and microvessels, and could be helpful for the diagnostic imaging and for the localization guidance. In this report, we presented two cases of peripheral pulmonary nodule. Under the guidance of X-ray and endobronchial ultrasound, needle-based confocal laser endomicroscopy (nCLE) could directly approach the peripheral pulmonary nodule via an exploratory puncture needle...

AIM: Needle visibility is crucial for effective and safe ultrasound-guided interventional procedures. Several studies have investigated needle visibility in 2D ultrasound imaging, but less information is available for 3D ultrasound imaging, a modality that has great potential for image guidance interventions. We performed a prospective study, to quantitatively compare the echogenicity of various commercially available needles in 3D ultrasound images used in clinical practice under freehand needle introduction...

Abdullah M Al Wahbi
BACKGROUND: Endoluminal laser ablation is now considered the method of choice for treating greater saphenous vein insufficiency. General anesthesia and peripheral nerve blocks with sedation have the risk of post-procedural delay in discharge and prolonged immobilization with the risk of deep vein thrombosis. The main pain experienced by patients during the procedure is during the laser ablation and the multiple needle punctures given along and around the great saphenous vein. The aim of our study was to evaluate the safety and efficacy of blocking the femoral nerve only under ultrasound-guidance without sedation, to reduce or prevent pain during injectable tumescent anesthesia in endovenous laser ablation of the greater saphenous vein...

BACKGROUND: This prospective, randomized trial compared neurostimulation (NS) and ultrasound (US) guided lateral femoral cutaneous nerve (LFCN) block. We hypothesized that US would result in a shorter total anesthesia-related time (sum of performance and onset times). METHODS: Twenty-one volunteers were enrolled. The right lower limb was randomized to an NS- or US-guided LFCN block. The alternate technique was employed for the left lower limb. With NS, paresthesias were sought in the lateral thigh at a stimulatory threshold of 0...

BACKGROUND: Fine-needle aspiration (FNA) of focal splenic lesions (FSL) is usually done under ultrasound (US) or computed tomography guidance. Endoscopic US (EUS), because of its ability to provide high-resolution images, can be used for aspirating FSL. We studied the safety and efficacy of EUS-guided FNA of FSL. METHODS: We performed a retrospective analysis of patients with FSL undergoing EUS-guided FNA over the last six years. RESULTS: EUS-guided FNA was performed in 16 patients (age: 28-43 years; male: 11)...

REVIEW
Bernd Saugel, Thomas W L Scheeren, Jean-Louis Teboul
The use of ultrasound (US) has been proposed to reduce the number of complications and to increase the safety and quality of central venous catheter (CVC) placement. In this review, we describe the rationale for the use of US during CVC placement, the basic principles of this technique, and the current evidence and existing guidelines for its use. In addition, we recommend a structured approach for US-guided central venous access for clinical practice. Static and real-time US can be used to visualize the anatomy and patency of the target vein in a short-axis and a long-axis view...
