OBJECTIVE Dunkin Hartley guinea pigs, a commonly used animal model of osteoarthritis, were used to determine if high frequency ultrasound can ensure intra-articular injections are accurately positioned in the knee joint. METHODS A high-resolution small animal ultrasound system with a 40 MHz transducer was used for image-guided injections. A total of 36 guinea pigs were anaesthetised with isof...
ULTRASOUND-GUIDED regional blocks are becoming increasingly popular among anesthesiologists. The ultrasonographic image allows real time visualization of anatomical structures, the progression of the needle, and the spread of the injected local anesthetic (LA). The visualization capabilities of ultrasound guidance (USG) are thought to increase the safety of regional blocks when compared with a ...
Background Serratus plane block is a thoracic truncal block that has been proposed as alternatives for analgesia such as epidural anesthesia and paravertebral block for the anterolateral chest wall. Previously, we performed the clinical study about optimal volume of the local anesthetic in serratus plane block. The primary aim of this study was to assess the pattern of distribution of dye into ...
BACKGROUND Blind injection of the subacromial-sub-deltoid bursa (SSB) for diagnostic purposes (Neer test) or therapeutic purposes (corticosteroid therapy) is frequently used. Poor response to previous blind injection or side effects may be due to a misplaced injection. It is assumed that ultrasound (US)-guided injections are more accurate than blind injections. In a randomized study, we compare...
Pseudoaneurysms of the inferior gluteal artery are rare. We describe a case of an inferior gluteal pseudoaneurysm that presented as a painful mass in the buttock. A percutaneous thrombin injection under ultrasound guidance failed to occlude the sac, probably due to the wide neck of the aneurysm. Subsequently, transluminal coil embolization by ultrasound-guided direct puncture of the inferior gl...
BACKGROUND The purpose of this study was to evaluate the feasibility of ultrasound-guided intratumoral indigo carmine injections for intraoperative localization of small head and neck tumors and to introduce our surgeon-performed technique. METHODS In total, 23 patients who had tumors ≤1.5 cm that were not palpable by 2 head and neck surgeons were enrolled in this prospective study. RESULTS...
Intra-articular injections have traditionally been performed "blind," guided only by anatomic palpation. Many may be placed inaccurately, and the use of imaging may significantly improve injection accuracy. This review analyzed the impact of ultrasound-guidance on injection accuracy and clinical efficacy in the knee and shoulder joints. Ultrasound-guided injections were significantly more accur...
conclusion lumbar medial branch nerve block under ultrasound guidance was associated with high rates of treatment success and excellent treatment outcomes for facet joint pain. it is also feasible and administers no radiation. thus, ultrasound-guided procedures can be used instead of conventional methods. results the success rate was 98% (87/89 blocks), which was due to our use of ultrasound gu...
