INTRODUCTION Fracture dislocations of the elbow appear extremely complex. Identification of the basic injury patterns can facilitate management. CASE PRESENTATION A 38-year-old male motor-vehicle driver who fell on his right elbow after an accident was suffering from posterior dislocation of the elbow, without coronoid fracture, and with fracture of the radial head and olecranon, and medial c...

DOI: 10.5935/abc.20140045 Clinical data: Surgical correction of pulmonary atresia with ventricular septal defect and aortopulmonary collateral arteries was performed in three steps. The first one, with 19 months, with the unification of major collateral artery in the right upper lobe (8 mm) to the right pulmonary artery (RPA), which nurtured the right lower lobe, and Blalock-Taussig anastomosis...

Function of the coronary collateral circulation during the course of a single abrupt coronary occlusion was evaluated in awake dogs instrumented over the long term. Studies were performed approximately 2 weeks after collateral development had been stimulated in the dogs by partial stenosis of the proximal left circumflex coronary artery. The pressure drop from the central aorta to the distal ci...

Purpose. To investigate the extrahepatic collateral arteries related to hepatic artery occlusion (HAO) and to determine its benefits in the transarterial management of liver tumors. Methods and Findings. Eleven patients (7 hepatocellular carcinomas, 3 liver metastases, and 1 with hemangioma) with HAO confirmed with digital subtraction angiography (DSA) were admitted to our hospital. Of the 11 p...

Arteriogenesis for Cerebral Ischemia To the Editor: The pioneering efforts in the development of therapeutic arteriogenesis for cerebral ischemia reported by Buschmann et al1 herald a new era in the field of stroke therapy. The role of collaterals in maintaining perfusion beyond the site of a proximal arterial occlusion has long been appreciated as a critical factor in reducing ischemic injury ...

A 47-year-old male patient with 3-vessel coronary artery disease underwent quadruple coronary artery bypass graft surgery (right internal mammary artery–right coronary artery [RIMA–RCA], left internal mammary artery–left anterior descending artery [LIMA–LAD], and radial artery– second posterolateral branch with jump anastomosis to the first posterolateral branch). Surgery was complicated by dif...

Collateral circulation plays an important role in protecting brain tissue from ischemic damage acute cerebral artery occlusion, and various imaging modalities are used to evaluate collateral circulation. Angiographic techniques, such as digital subtraction angiography multiphase computed tomography (CT) angiography, directly show Meanwhile, hyperintense vessels on f luid-attenuated inversion re...

BACKGROUND AND PURPOSE The anterior communicating artery (AcoA) and posterior communicating arteries (PcoA) of the circle of Willis provide the main route for collateral blood flow in cases of carotid artery obstruction. Transcranial color-coded duplex ultrasonography (TCCD) allows real-time measurement of the collateral function of the AcoA and PcoA. The primary objective of this study was to ...
