Decompressive Contrast ultrasound

Surgical treatment of celiac artery (CA) compression syndrome (CACS) is to release the median arcuate ligament (MAL) by removing the abdominal nerve plexus surrounding CA. In laparoscopic surgery of CACS, objective intraoperative assessment of blood flow in CA is highly desirable. We herein demonstrate a case of laparoscopic surgery of CACS with use of intraoperative transabdominal ultrasound. A 52-year-old woman was presented with epigastric pain and vomiting after eating. Contrast-enhanced computed tomography demonstrated significant stenosis at the origin of CA...

The incidence of bile leaks following blunt liver trauma ranges from 0.5% to 21%. Bile leaks could give rise to biliopleural fistula, which can end up causing cholethorax, where a bilious effusion is seen in the pleural cavity. Early recognition of this condition is essential for favorable outcome. We report an unusual case of delayed biliopleural fistula causing cholethorax in a 30-year-old male, presented following blunt abdominal trauma following a motor vehicle collision. Abdominal examination revealed tender right upper quadrant...

A parallel shunt (PS) is often necessary to regain portal decompression in a dysfunctional transjugular intrahepatic portosystemic shunt (TIPS). Here, we successfully utilized the gun-sight technique to create a PS. An 81-year-old male with decompensated NASH cirrhosis and recent TIPS placement presents with recurrent ascites and pleural effusions in the setting of a persistent portosystemic gradient. Due to a lack of access to endovascular ultrasound and complex patient anatomy, a gun-site technique was approached to create a PS (left portal vein [PV] to left hepatic vein [HV])...

INTRODUCTION: The aim of this study was to assess clinical outcomes and quality of life after PFO closure in patients with previous stroke/TIA of undetermined cause and in patients with other complex PFO-associated clinical conditions. METHODS: Between July 2009 and December 2019 at our University Cardiology Department, 118 consecutive patients underwent a thorough diagnostic work-up including standardized history taking, clinical evaluation, full neurological examination, screening for thrombophilia, brain magnetic resonance imaging (MRI), ultrasound-Doppler sonography of supra-aortic vessels and 24 h ECG Holter monitoring...

OBJECTIVE: Supraspinatus tendon (SSP) tears are a frequent indication for shoulder surgery. Therapy options include physiotherapy, tendon repair and less invasive surgical options like subacromial decompression (SAD). The selection of the most appropriate treatment depends on the specific characteristics and needs of each patient subgroup. Typically, physically active patients are candidates for tendon repair, while a conservative approach is preferred for individuals with severe muscle degeneration or low physical demands...

Acute cholecystitis is the most common presentation of gallbladder (GB) disease. It has an incidence of around 200,000 cases a year in the United States (US) and affects approximately 20 million individuals in the US. In most cases, it presents with a history of symptomatic gallstones. Initial management includes intravenous hydration and antibiotics, bowel rest, and analgesia. Complicated cases are typically resolved with surgery (laparoscopic cholecystectomy). The pathogenesis of acute cholecystitis is most often explained by obstruction of the cystic duct...

Upper extremity deep vein thrombosis (UEDVT) is less common than lower extremity DVT but is a cause of significant morbidity and mortality in intensive care unit patients. Increasing cancer incidence, prolonged life expectancy and increasing use of intravascular catheters and devices has led to an increased incidence of UEDVT. It is also associated with high rates of complications like pulmonary embolism, post-thrombotic syndrome and recurrent thrombosis. Clinical prediction scores and D-dimer may not be as useful in identifying UEDVT; hence, a high suspicion index is required for diagnosis...

INTRODUCTION: Surgical decompression is a highly effective therapy for degenerative cervical myelopathy (DCM), but the mechanisms of neurological recovery following decompression remain unclear. This study aimed to evaluate the spinal cord blood flow status after sufficient decompression by intraoperative contrast-enhanced ultrasonography and to analyse the correlation between neurological recovery and postdecompressive spinal cord blood perfusion in DCM. METHODS: Patients with multilevel DCM were treated by ultrasound-guided modified French-door laminoplasty using a self-developed rongeur...

Children with hypoplastic left heart syndrome share unique hemodynamic features that alter lymphatic integrity at all stages of palliation. Lymphatic congestion is almost universal in this patient group to some extent. It may lead to reversal of lymphatic flow, the development of abnormal lymphatic channels and ultimately decompression and loss of protein rich lymphatic fluid into extra lymphatic compartments in prone individuals. Some of the most devastating complications that are associated with single ventricle physiology, notably plastic bronchitis and protein losing enteropathy, have now been proven to be lymphatic in origin...

OBJECTIVES: To compile intra-operative techniques, established imaging parameters, available equipment and software, and clinical applications of intraoperative ultrasound imaging (IOUSI) for spinal cord injury (SCI) and myelopathy. METHODS: PubMed and Google Scholar were searched for relevant articles. The articles were reviewed and selected by two independent researchers. After article selection, data was extracted and summarized into research domains. PRISMA systematic review process was followed...

Primary percutaneous gastrostomy and gastrojejunostomy tube placements are fundamental procedures performed in pediatric interventional radiology, with both antegrade and retrograde techniques described. In pediatric patients, however, challenges may arise due to smaller patient size and anatomical variations. Several adjunctive techniques may facilitate safe percutaneous access in the setting of a limited percutaneous gastric access window. These include the intra-procedural use of cone beam computed tomography (CT), percutaneous needle decompression in the setting of distended air-filled bowel interposed between the stomach and abdominal wall, post-pyloric balloon occlusion to facilitate gastric distension, ultrasound-guided gastric puncture, and intra-gastric contrast-enhanced ultrasound (ceUS) to define the relationship of the gastric wall and the anterior abdominal wall...

Ultrasound monitoring, both in the form of Doppler and 2D echocardiography, has been used post-dive to detect decompression bubbles circulating in the bloodstream. With large variability in both bubble time course and loads, it has been hypothesised that shorter periods between imaging, or even continuous imaging, could provide more accurate post-dive assessments. However, while considering applications of ultrasound imaging post-decompression, it may also be prudent to consider the possibility of ultrasound-induced bioeffects...

INTRODUCTION AND IMPORTANCE: We present the case in which a large symptomatic pseudoaneurysm (PSA), 6 × 5 cm, with one year of evolution on the path of the right radial artery (RRA) appeared after its punction and cannulation for performing cardiac catheterism in an atrial fibrillation (AF) indefinite anticoagulated patient. Diagnosis and surgical planning were consolidated only by using color duplex ultrasound (CDU), contrasted images were not indicated. The open surgical management was performed during a short-time supraclavicular blockade of peripheral nerves without stopping nor bridging anticoagulant therapy...

Patients with unresectable malignant biliary obstruction often require biliary drainage to decompress the biliary system. Endoscopic Retrograde Cholangiopancreatography (ERCP) is the primary biliary drainage method whenever possible. Percutaneous Transhepatic Biliary Drainage (PTBD) is used as a salvage method if ERCP fails. Endoscopic Ultrasound-Guided Biliary Drainage (EUS-BD) provides a feasible alternative biliary drainage method where one of the methods is EUS guided Hepaticogastrostomy (EUS-HGS). Here we describe the EUS-HGS technique in a case of unresectable malignant hilar biliary obstruction to achieve biliary drainage...

OBJECTIVE: To report the diagnostic features and clinical outcome of horses with digital flexor tendon sheath (DFTS) synoviocoeles treated tenoscopically under ultrasonographic guidance. STUDY DESIGN: Retrospective case series. ANIMALS: Client-owned horses (n = 10). METHODS: Medical records were searched for horses with lameness localized to the region of the DFTS and clinical evidence of a fluid-filled mass (synoviocoele) associated with the DFTS...

Due to incompatibility with magnetic resonance imaging, patients with left ventricular assist devices (LVADs) presenting with pathologies of the spinal soft tissues or neural elements represent diagnostically complex cases. We present a case of a patient undergoing a CT (computed tomography) myelogram and subsequent successful cervical posterior laminectomy. A C1-C2 lateral puncture approach CT myelogram revealed nearly a complete block of contrast movement at the level of the C2-C3 vertebrae concerning a compressive etiology...

Venous thoracic outlet syndrome (vTOS) is a spectrum of disease caused by external compression of the subclavian vein as it passes through the costoclavicular space. Paget-Schroetter's Syndrome (PSS) or effort thrombosis is a subtype of vTOS where compression and microtrauma to subclavian vein from repetitive arm movements results in venous thrombosis. PSS or effort thrombosis mostly affects young otherwise healthy active individuals, and this further highlights the importance of this condition. Early diagnosis and aggressive early intervention aimed at complete resolution of acute symptoms and minimizing the risk of recurrence is ultimately important and increases the likelihood of the full restoration of limb function...

Acute mesenteric ischemia is a rare, life-threatening complication of cervical cord injury. This case report emphasized the importance of prompt diagnosis and treatment of this complication. A 60-year old Japanese man with no co-morbidities was diagnosed as a C2 cervical cord injury and traumatic brain injury after a fall-down trauma. He was admitted to the intensive care unit after cord decompression surgery. Nine days later, he presented tachycardia and hypotension. Ultrasound showed dilated intestines and ascites...
