BACKGROUND The optimal site for local anesthetic placement during ultrasound-guided infraclavicular block remains controversial. METHODS Patients were randomized to receive lidocaine 2% 30 mL as a single injection posterior to the axillary artery (n = 51) or a triple injection ideally adjacent to each brachial plexus cord (n = 49). Pinprick sensory and motor block (3 = no block, 0 = complete ...

BACKGROUND Pseudoaneurysm occurring after catheterization of the femoral artery is associated with significant morbidity. Percutaneous ultrasound-guided thrombin injection has recently emerged as a potential first-line therapy. OBJECTIVES To evaluate the efficacy of this treatment in eight patients with iatrogenic femoral artery pseudoaneurysm. METHODS After attempted treatment with externa...

Objective. This present study aimed to explore the clinical effects of ultrasound-guided (USG) mechanical needling with sterile water injection for lumbar facet joint syndrome. Methods. was a retrospective cohort that assessed outcome ageing patients who received USG injection. In addition, age- and gender-matched randomly selected from compared injected steroids in 2 : 1 ratio. The data were e...

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 ...

OBJECTIVES To describe our technique and initial experience of intraoperative tumor localization with surgeon-performed ultrasound-guided needle dye injection. STUDY DESIGN Prospective case series. Technique description. METHODS Using surgeon-performed ultrasonography (SP-US), 20 tumors (lymph node metastases of papillary thyroid carcinoma [15], Hurthle cell carcinoma [2], medullary thyroid...

BACKGROUND Myofascial pain is defined as pain that originates from myofascial trigger points in skeletal muscle. It is prevalent in regional musculoskeletal pain syndromes, either alone or in combination with other pain generators. The myofascial pain syndrome is one of the largest groups of under diagnosed and under treated medical problems encountered in clinical practice. Trigger points are ...

Plancarte first described a fluoroscopy-guided superior hypogastric plexus block to manage pelvic pain in 1990. Modifications have since been described using different imaging modalities. Ultrasound-guided approach has been described in a clinical outcome study. However, the accuracy of an ultrasound-guided method has never been validated by alternative imaging. We conducted an experiment aimin...

PURPOSE In this narrative review, we aim to provide the pathophysiology and diagnostic criteria of the piriformis syndrome (PS), an underdiagnosed cause of buttock and leg pain that can be difficult to treat. Based on existing evidence, frequencies of clinical features are estimated in patients reported to have PS. In view of the increasing popularity of ultrasound for intervention, the ultraso...

We report a case of a 71-year old woman with right inferior epigastric artery pseudoaneurysm following laceration by a computed tomography-guided 18G biopsy needle. The laceration was initially treated with placement of retained sutures; however the patient turned hemodynamically unstable 41 days later. Percutaneous ultrasound-guided injection of 1500 U of thrombin solution resulted in almost c...
