Real-Time Volumetric Phase Monitoring: Advancing Chemical Analysis by Countercurrent Separation.

Countercurrent separation (CCS) utilizes the differential partitioning behavior of analytes between two immiscible liquid phases. We introduce the first platform ("CherryOne") capable of real-time monitoring, metering, and control of the dynamic liquid-liquid CCS process. Automated phase monitoring and volumetrics are made possible with an array of sensors, including the new permittivity-based phase metering apparatus (PMA).

Interventional radiology for paediatric trauma.

Paediatric interventional radiology plays a cornerstone role in the management of paediatric trauma. In the acute setting, interventional radiology techniques allow minimally invasive control of haemorrhage or re-establishment of blood flow. Percutaneous stenting and drainage can allow disruptions in urinary or biliary systems to heal without the need for further surgery.

Bronchial artery embolization for hemoptysis.

Bronchial artery bleeding is the most common cause of life-threatening hemoptysis. The most common underlying etiologies include tuberculosis, bronchiectasis, aspergillosis, and cystic fibrosis. Bronchial artery embolization is an important treatment for significant hemoptysis, given its high early success rate and relatively low risk compared with alternative medical and surgical treatments.

Visceral trauma: principles of management and role of embolotherapy.

Interventional radiology for the treatment of traumatic visceral hemorrhage has emerged as an important adjunct to modern trauma care. This article outlines the general surgical concepts of the acute care of trauma patients as a guideline for catheter-based therapy. Specific considerations are presented for embolizing visceral injuries in the liver, spleen, and kidney.

Which Arteries Are Expendable? The Practice and Pitfalls of Embolization throughout the Body.

This article outlines general concepts of, and strategies for, therapeutic embolization throughout the body, touching on all major arterial distributions. Clinical scenarios that allow or prevent safe embolization of vessels are presented. Specific agents are recommended where appropriate, as are alternate approaches when embolization is not an option.

Indeterminate CT angiography in blunt thoracic trauma: is CT angiography enough?

Objective: The primary objective of our study was to determine whether catheter angiography is needed to exclude aortic and intrathoracic great vessel injury when CT angiography (CTA) findings are indeterminate (mediastinal hematoma without direct evidence of aortic or intrathoracic great vessel injury). The secondary objective was to devise a classification scheme for mediastinal hematomas.

Materials And Methods: This study is a retrospective analysis of patients presenting with blunt trauma over 4.

The use of paired optionally retrievable günther tulip filters in trauma patients with anatomical variants.

Inferior vena cava (IVC) filtration is commonly performed to protect against pulmonary embolism in acutely injured patients with contraindications for anticoagulation therapy. Increasingly, optionally retrievable IVC filters are utilized, particularly in younger patients with longer life expectancies. There are well-described anatomical variants that preclude the typical infrarenal deployment of IVC filters.

Practice patterns and outcomes of retrievable vena cava filters in trauma patients: an AAST multicenter study.

Background: The purpose of this study is to describe practice patterns and outcomes of posttraumatic retrievable inferior vena caval filters (R-IVCF).

Methods: A retrospective review of R-IVCFs placed during 2004 at 21 participating centers with follow up to July 1, 2005 was performed. Primary outcomes included major complications (migration, pulmonary embolism [PE], and symptomatic caval occlusion) and reasons for failure to retrieve.

Hemothorax complicating bronchial artery aneurysm.

An elderly patient presented with spontaneous hemothorax. Workup identified a right-sided bronchial aneurysm as the source, which was successfully embolized. Bronchial aneurysms can be managed by interventional techniques, although the choice of approach depends upon the clinical and anatomical settings.
