BACKGROUND: The plantaris tendon (PT) has been implicated in the pathogenesis of symptoms in a subset of patients with Achilles region pain syndromes and has been traditionally managed via open surgical resection. Although the PT can be visualized on ultrasound, a minimally invasive technique for sonographically guided PT release has not been formally described. OBJECTIVE: To validate a technique to perform sonographically guided PT release in an unembalmed cadaveric model...

BACKGROUND AND OBJECTIVES: For superficial surgery of anteromedial and posteromedial surfaces of the upper arm, the medial brachial cutaneous nerve (MBCN) and the intercostobrachial nerve (ICBN) must be selectively blocked, in addition to an axillary brachial plexus block. We compared efficacy of ultrasound-guided (USG) versus conventional block of the MBCN and the ICBN. METHODS: Eighty-four patients, undergoing upper limb surgery, were randomized to receive either USG (n = 42) or conventional (n = 42) block of the MBCN and the ICBN with 1% mepivacaine...

BACKGROUND AND OBJECTIVES: Percutaneous peripheral nerve stimulation (PNS) is an analgesic modality involving the insertion of a lead through an introducing needle followed by the delivery of electric current. This modality has been reported to treat chronic pain as well as postoperative pain the day following knee surgery. However, it remains unknown if this analgesic technique may be used in ambulatory subjects following foot procedures beginning within the recovery room immediately following surgery, and with only short series of patients reported to date, the only available data are derived from strictly observational studies...

Focused ultrasound (FUS)-mediated blood-brain barrier (BBB) opening recently entered clinical testing for targeted drug delivery to the brain. Sources of variability exist in the current procedures, motivating the development of real-time monitoring and control techniques to improve treatment safety and efficacy. Here we used three-dimensional (3D) transcranial microbubble imaging to calibrate FUS exposure levels for volumetric BBB opening. Methods: Using a sparse hemispherical transmit/receive ultrasound phased array, pulsed ultrasound was focused transcranially into the thalamus of rabbits during microbubble infusion and multi-channel 3D beamforming was performed online with receiver signals captured at the subharmonic frequency...

A 63-year-old white man with no significant previous medical or surgical history presented with painless jaundice after 3 weeks of dark urine, yellow stools, and a 9-pound weight loss. Bilirubin, aspartate transaminase, alanine transaminase, and alkaline phosphatase were elevated, and a computed tomography scan detected a 10-cm, ill-defined mass at the porta hepatis compressing the common bile duct. He underwent endoscopic retrograde cholangiopancreatography with stenting and ultrasound-guided biopsies. Histologic sections showed a neoplastic population of small ovoid cells with a high N:C ratio, nuclear hyperchromasia, "smoky" chromatin and abundant mitotic figures, and characteristic of high-grade neuroendocrine carcinoma (HGNECA)...

The diagnosis of malignant biliary strictures remains problematic, especially in the perihilar region and in primary sclerosing cholangitis (PSC). Conventional cytology obtained during endoscopic retrograde cholangiography (ERC)-guided brushings of biliary strictures is suboptimal due to limited sensitivity, albeit it remains the gold standard with a high specificity. Emerging technologies are being developed and validated to address this pressing unmet patient need. Such technologies include enhanced visualization of the biliary tree by cholangioscopy, intraductal ultrasound, and confocal laser endomicroscopy...

Prostate cancer is the most commonly diagnosed noncutaneous cancer and second leading cause of death in men. Many patients with clinically organ-confined prostate cancer undergo definitive treatment of the whole gland, including radical prostatectomy, radiation therapy, and cryosurgery. Active surveillance is a growing alternative option for patients with documented low-volume and low-grade prostate cancer. However, many patients are wanting a less morbid focal treatment alternative. With recent advances in software and hardware of magnetic resonance imaging (MRI), multiparametric MRI of the prostate has been shown to improve the accuracy in detecting and characterizing clinically significant prostate cancer...

BACKGROUND: Pain following bariatric surgery can be quite troublesome and prolongs recovery. Transversus abdominis plane (TAP) block is a new regional anesthetic technique to reduce postoperative pain and is an important part of current analgesic regimen for many abdominal surgeries. The primary objective of our study was to assess the efficacy of the TAP block in controlling postoperative pain in laparoscopic sleeve gastrectomy. Secondary outcomes assessed in this study were postoperative nausea and vomiting (PONV), time to ambulate, readiness for discharge, and whether it leads to improved patient satisfaction...

BACKGROUND: Ultrasound, nerve stimulation, and their combination are all considered acceptable ways to guide peripheral nerve blocks. Which approach is most effective and associated with the fewest complications is unknown. We therefore used a large registry to analyze whether there are differences in vascular punctures, multiple skin punctures, and unintended paresthesia. METHODS: Twenty-six thousand seven hundred and thirty-three cases were extracted from the 25-center German Network for Regional Anesthesia registry between 2007 and 2016 and grouped into ultrasound-guided puncture (n = 10,380), ultrasound combined with nerve stimulation (n=8173), and nerve stimulation alone (n = 8180)...

PURPOSE: Laparoscopic ultrasound (LUS) enhances the safety of laparoscopic liver resection by enabling real-time imaging of internal structures such as vessels. However, LUS probes can be difficult to use, and many tumours are iso-echoic and hence are not visible. Registration of LUS to a pre-operative CT or MR scan has been proposed as a method of image guidance. However, the field of view of the probe is very small compared to the whole liver, making the registration task challenging and dependent on a very accurate initialisation...

Prosthetic hip dislocation is a common but unfortunate complication in patients who have undergone total hip arthroplasty. Successful closed reduction in the emergency department leads to a reduced length of stay and rate of hospitalization.1,2 The use of regional anesthesia by femoral nerve block represents a novel approach for controlling pain in patients with hip pathologies.3 Ultrasound-guided approaches have been used with great success for controlling pain in patients with hip fractures.4,5 Here we report the case of a 90-year-old male who presented with a dislocated hip prosthesis, which was subsequently corrected with closed reduction following delivery of regional anesthesia to the femoral nerve under ultrasound guidance...

BACKGROUND: The ultrasound-guided transversus abdominis plane (TAP) block is generally used for analgesia but not for anesthesia. A TAP block has a partial analgesic effect on the parietal peritoneum in abdominal surgeries. We hypothesized that an ultrasound-guided oblique subcostal TAP block, used as the principal anesthesia technique, could provide a better anesthetic effect on peritoneum stimulation in peritoneal dialysis catheter (PDC) implantation in end-stage renal diseases (ESRD) patients than local anesthetic infiltration (LAI)...

BACKGROUND: The demand for total knee arthroplasty (TKA) is rising worldwide. Controversy persists in the literature regarding the benefits of general vs. neuraxial anesthesia and which anesthetic is associated with the best outcomes. Likewise, the abundance of analgesic options for post-TKA pain have led to debate regarding the safest, most effective regimens. METHODS: In this narrative review, we evaluated a selection of recent publications regarding anesthetic and analgesic choices for TKA...

Orofacial myofascial pain is prevalent and most often results from entrapment of branches of the trigeminal nerves. It is challenging to inject branches of the trigeminal nerve, a large portion of which are shielded by the facial bones. Bony landmarks of the cranium serve as important guides for palpation-guided injections and can be delineated using ultrasound. Ultrasound also provides real-time images of the adjacent muscles and accompanying arteries and can be used to guide the needle to the target region...
