BACKGROUND: There are limited reports of lumbar neuraxial blocks using real-time ultrasound in patients with predicted difficulties. We compared the number of attempts to perform spinal anesthesia using real time ultrasound guidance versus landmark technique in patients meeting predefined criteria for difficult spinal anesthesia. We also compared procedure time, block success, patient satisfaction and difficulty scores between groups. METHODS: Following institutional review board approval patients scheduled for total hip or knee arthroplasty with expected difficulty to perform spinal anesthesia were included...

BACKGROUND: Peripheral nerve stimulation has been used for decades to treat chronic pain but has not been used for postoperative analgesia due to multiple limitations, beginning with invasive electrode placement. With the development of small-diameter/gauge leads enabling percutaneous insertion, ultrasound guidance for accurate introduction, and stimulators small enough to be adhered to the skin, neurostimulation may now be provided in a similar manner to continuous peripheral nerve blocks...

BACKGROUND AND OBJECTIVES: Ultrasound-guided regional anesthesia facilitates an approach to sensitive targets such as nerve clusters without contact or inadvertent puncture. We compared accuracy of needle placement with a novel passive magnetic ultrasound needle guidance technology (NGT) versus conventional ultrasound (CU) with echogenic needles. METHODS: Sixteen anesthesiologists and 19 residents performed a series of 16 needle insertion tasks each, 8 using NGT (n = 280) and 8 using CU (n = 280), in high-fidelity porcine phantoms...

Background Infiltrations from cannulation result in significant morbidity including loss of hemodialysis (HD) vascular access (VA). Cannulation is dependent on personnel skill and VA characteristics. Surface marking of VA lacks real-time information and traditional ultrasound (US) devices are large, expensive, requiring skilled operators. Sonic Window© (Analogic Ultrasound, Peabody, MA, USA) is a coronal mode ultrasound device (CMUD) approved for VA cannulation. Methods Single center randomized, prospective pilot study comparing handheld US-guided cannulation of new arteriovenous fistula (AVF) to standard cannulation practices...

The diagnosis and staging of patients with lung cancer has relied on tissue sampling. Endobronchial ultrasound (EBUS) is a minimally invasive procedure for the rapid and safe acquisition of tissue and can be done easily and repeatedly. EBUS transbronchial needle aspiration (TBNA) is now the standard for diagnosis of mediastinal and hilar lymphadenopathy and should be considered in patients who have a high probability of lymph node metastases without systemic involvement. EBUS also provides guidance for biopsy of peripheral lung lesions...

INTRODUCTION: A rapidly enlarging mass of the anterior compartment of the neck with compressive symptoms may represent, among other diagnosis, a neoplasm of the thyroid gland. PRESENTATION OF CASE: We describe the case of a 59-year-old woman referred to the endocrine surgical unit because of compressive cervical symptoms for 3 months. The cervical ultrasound revealed a sub-sternal goiter with heterogeneous echo structure and the fine-needle aspirating cytology was inconclusive...

PURPOSE: The objective of this research was to demonstrate accuracy of a real-time passive ultrasound magnetic needle guidance technology (NGT) and target localization algorithm using conventional anechogenic contact phantoms and a novel fluid-filled hyperechogenic phantom simulating nerve block technique. METHODS: Accuracy (mm to phantom target) was assessed by observing 35 medical practitioners (16 anesthesiologists and 19 residents) performing 560 needle procedures in high-fidelity ex vivo porcine tissue phantoms...

PURPOSE: Prostate brachytherapy is an effective treatment for early prostate cancer. The current prostate implant is limited to using 2D transrectal ultrassound (TRUS) or machenical motor driven 2D array either in the end or on the side. Real-time 3D images can improve the accuracy of the guidance of prostate implant. The concept of our system is to allow realtime full visualization of the entire prostate with the multiple transverse scan. METHODS: The prototype of 3D Multiple-Transverse-Plane Transrectal Ultrasound probe (MTP-TRUS) has been designed by us and manufactured by Blatek inc...

Image-guided biopsy and ablation relies on successful identification and targeting of lesions. Currently, image-guided procedures are routinely performed under ultrasound, fluoroscopy, magnetic resonance imaging, or computed tomography (CT) guidance. However, these modalities have their limitations including inadequate visibility of the lesion, lesion or organ or patient motion, compatibility of instruments in an magnetic resonance imaging field, and, for CT and fluoroscopy cases, radiation exposure. Recent advances in technology have resulted in the development of a new generation of navigational guidance tools that can aid in targeting lesions for biopsy or ablations...

Thyroid nodules constitute by far the most common disorder of the endocrine system. Epidemiological studies have indicated that approximately 5% of women and 1% of men resident in iodine-sufficient areas have palpable thyroid nodules. However, by the age of 60 years about 50% of the general population is estimated to have at least one thyroid nodule. Indeed, the reported prevalence of a "thyroid incidentaloma" is up to 70% when neck/carotid artery ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) is performed for other indications...

The real-time nature of ultrasound makes it ideally suited to provide guidance for a variety of musculoskeletal interventional procedures involving peripheral nerves. Continuous observation of the needle ensures proper placement and allows continuous monitoring when performing localized ablative therapy and therefore more accurate positioning of a cryoprobe, use of smaller needles, as well as access to small structures. We describe our experience performing cryoablative procedures. Patients undergoing cryoneurolysis have largely reported varying degrees of long-term pain relief and improvement in function; no serious complications have yet been identified...

This article is a practical review update on ultrasound (US)-guided interventional procedures on peripheral nerves. Technical considerations, biopsy techniques, and some examples of injections are described. US is considered a safe imaging guidance for interventional procedures, due to its high spatial resolution and the possibility to image the needle and inject drugs in real time. US-guided injections could be considered a diagnostic and therapeutic option in the most common neuropathy, before or as an alternative to surgery...

Of the many treatment options for tendinopathy, percutaneous tenotomy has been used throughout the body with success. With this procedure, a needle is repeatedly passed into the abnormal tendon with the goal of converting a chronic degenerative process to an acute inflammatory condition that will progress to tendon healing. Ultrasound guidance for this procedure is essential to ensure that the abnormal region of the tendon is accurately targeted. The treatment has few contraindications, and negligible complications have been described...

BACKGROUND AND OBJECTIVES: The placement of thoracic epidurals can be technically challenging and requires a thorough understanding of neuraxial anatomy. Although ultrasound imaging of the thoracic spine has been described, no outcome studies on the use of this imaging have been performed. We evaluated whether preprocedural ultrasound of the thoracic spine would facilitate the process of epidural catheterization. METHODS: Subjects undergoing thoracic or upper abdominal surgery with planned thoracic epidural placement at T10 or higher were enrolled in this randomized double-blind study...

BACKGROUND: Secure, permanent occlusion of the great and small saphenous veins, their tributaries, and perforators is critical for the successful treatment of varicose veins. Current minimally invasive methods replacing surgery are all endoluminal and involve heat (radiofrequency or laser), chemicals (sclerosants and glues), or a combination of mechanical and chemical interventions. This study evaluated in a porcine model the performance of a percutaneous delivery of the Amsel Vessel Occluder (AVO; Amsel Medical Corp, Cambridge, Mass) using ultrasound guidance...
