BACKGROUND: An interventional procedure like celiac plexus neurolysis (CPN) has a significant role in relieving intractable pain in patients with locally advanced abdominal malignancies. Ultrasound (USG) guidance enables performance of bedside CPN by real-time visualization of the needle trajectory. The objective of the study was to perform percutaneous USG-guided CPN and to verify technical outcomes of the procedure using a post-procedure CT scan. METHODS: Eleven eligible patients of advanced upper abdominal malignancies having a pain score of >3/10 on visual analog scale (VAS) were recruited to undergo CPN...

PURPOSE: To evaluate image-guided bone biopsy for bone histomorphometry to assess osteoporosis in children with respect to safety and yield. MATERIALS AND METHODS: A single-center retrospective review was performed of 79 bone biopsies in 73 patients performed between 2007 and 2015. Biopsies of the iliac bone were performed under general anesthesia, after tetracycline labeling, using a Rochester needle (Medical Innovations International, Inc, Rochester, Minnesota)...

Accurate identification of the needle target is crucial for effective epidural anesthesia. Currently, epidural needle placement is administered by a manual technique, relying on the sense of feel, which has a significant failure rate. Moreover, misleading the needle may lead to inadequate anesthesia, post dural puncture headaches and other potential complications. Ultrasound offers guidance to the physician for identification of the needle target, but accurate interpretation and localization remain challenges...

Ultrasound (USG) guidance has long been used for guiding central venous catheterization. USG provides direct visualization of needle puncture through the skin into the vein. Most of the time USG guidance is just limited to puncturing of the vein and seeing guidewire entering the vein while malpositioning of catheter occurs after that which is seen later on while checking chest radiograph. Repositioning of catheter after that becomes not only difficult requiring repeated chest radiograph to reconfirm position of catheter but also increases chances of infection with repeated manipulations...

Despite its popularity, ultrasound (US)-guided regional anesthesiology is associated with significant limitations. The latter can be attributed to either the US machine (ie, decreased ability to insonate deep neural structures, as well as the thoracic spine) or the operator. Shortcomings associated with the operator can be explained by errors in perception (ie, ambiguous criteria for needle/catheter tip-to-nerve proximity and subparaneural local anesthetic injection) or interpretation. Perhaps the greatest confusion afflicting US-guided regional anesthesiology originates from an intellectual misconception pertaining to its application...

The use of an automated biopsy device, and real-time ultrasound for percutaneous kidney biopsies (PKBs) has improved the likelihood of obtaining adequate tissue for diagnosis and also has reduced the complications associated with the procedure. We aimed to determine the frequency and type of complications associated with PKB and to determine the diagnostic yield. It was a retrospective file-based review of cases who underwent PKB of native kidney between January 2003 and December 2013 at the Aga Khan University Hospital in Karachi, Pakistan...

Endoscopic ultrasound (EUS) has evolved from a purely diagnostic to an interventional modality offering minimally invasive alternatives to surgical and radiologic interventions. This has led to a rapidly growing interest in EUS-guided vascular interventions. EUS-guided portal venous access is an emerging technique which opens a new arena for interventional vascular EUS. Portal vein can be accessed under EUS guidance with high precision and low risk of complications thus expanding its application for both benign and malignant conditions...

There remains a need for large animal models to evaluate tissue engineered vascular grafts (TEVGs) under arterial pressure to provide preclinical data for future potential human clinical trials. We present a comprehensive method for the interrogation of TEVGs, using an ovine bilateral arteriovenous shunt implantation model. Our results demonstrate that this method can be performed safely without complications, specifically acute heart failure, steal syndrome, and hypoxic brain injury and is a viable experimental paradigm...

Ultrasound (US) is often used to guide various interventional procedures in the genitourinary Epub ahead of print (GU) tract because it can provide real-time imaging without any radiation hazard. Moreover, US can clearly visualize the pathway of an aspiration or biopsy needle to ensure the safety of the intervention. US guidance also helps clinicians to access lesions via the transabdominal, transhepatic, transvaginal, transrectal, and transperineal routes. Hence, US-guided procedures are useful for radiologists who wish to perform GU interventions...

A novel full-inversion-based technique for quantitative ultrasound elastography was investigated in a pilot clinical study on five patients for non-invasive detection and localization of prostate cancer and quantification of its extent. Conventional-frequency ultrasound images and radiofrequency (RF) data (~5 MHz) were collected during mechanical stimulation of the prostate using a transrectal ultrasound probe. Pre and post-compression RF data were used to construct the strain images. The Young's modulus (YM) images were subsequently reconstructed using the derived strain images and the stress distribution estimated iteratively using finite element (FE) analysis...

PURPOSE: To identify clinicopathologic, technical, and imaging features associated with neoplastic seeding (NS) following image-guided needle breast biopsy. METHODS: We performed an institutional review board-approved retrospective review of patients presenting with a new diagnosis of breast cancer or suspicious breast findings requiring biopsy with subsequent diagnosis of NS. The time from biopsy to NS diagnosis was calculated. Histology, grade, estrogen receptor (ER) status, progesterone receptor (PR) status, HER2 status, T category, and N category were recorded...

BACKGROUND AND AIM: Complete gastrointestinal strictures are a technically demanding problem. In this setting, an anterograde technique is associated with a high risk of complications and a combined anterograde-retrograde technique requires a prior ostomy. Our aim was to assess the outcome of a first case series for the management of complete gastrointestinal strictures using endoscopic ultrasound (EUS)-guided puncture as a novel endoscopic approach. PATIENTS AND METHODS: This retrospective case-series describes four cases that were referred for treatment of complete benign gastrointestinal strictures, three upper and one lower...

PURPOSE: Radiofrequency ablation for liver tumors (liver RFA) is widely performed under ultrasound guidance. However, discriminating between the tumor and the needle is often difficult because of cavitation caused by RFA-induced coagulation. An unclear ultrasound image can lead to complications and tumor residue. Therefore, image-guided navigation systems based on fiducial registration have been developed. Fiducial points are usually set on a patient's skin. But the use of internal fiducial points can improve the accuracy of navigation...

In pigs, the deep location of the common carotid artery and overlying sternomastoideus muscle in the neck has led to the recommendation for a surgical cutdown for common carotid access, as opposed to minimally invasive techniques for vascular access. We sought to determine if direct percutaneous common carotid artery access in piglets is attainable. Seventeen piglets were anesthetized and intubated. Under two-dimensional and color flow Doppler ultrasound guidance, a 21 gauge needle was utilized to access the right common carotid artery...
