The distance of cervical vertebral dislocation could be a risk factor for blunt vertebral artery injury after traumatic cervical spine injury

ConclusionsBVAI frequently occurred in combination with cervical spine dislocation, and the distance of the cervical dislocation was identified as a useful predictor of BVAI.

Study Design. Retrospective cohort study. Objective. Compare a novel two-step algorithm for indicating a computed tomography angiography (CTA) in the setting of a cervical spine fracture with established gold standard criteria. Summary of Background Data. As CTA permits the rapid detection of blunt cerebrovascular injuries (BCVI), screening criteria for its use have broadened. However, more recent work warns of the potential for the overdiagnosis of BCVI, which must be considered with the adoption of broad criteria. Methods. A novel two-step metric for indicating CTA screening was compared with the American Coll...

[ESC guidelines 2019 on chronic coronary syndrome (CCS, previously "stable coronary artery disease") : What is new? What is particularly important?] Herz. 2019 Nov 11;: Authors: Silber S Abstract After an unusually long period of time of 6 years, in August 2019 the updated version of the European Society of Cardiology (ESC) guidelines from 2013 on the management of stable coronary artery disease was published. The course of "stable" coronary artery disease is only assumed to be stable and pathologically is often progressive but initially goes unnoticed. In order to raise awareness f...

Authors: Sorimachi T, Atsumi H, Yonemochi T, Hirayama A, Shigematsu H, Srivatanakul K, Takizawa S, Matsumae M Abstract Computed tomography angiography (CTA) immediately after diagnosis of intracerebral hematoma (ICH) on noncontrast CT in the emergency room has benefits, which consist of early diagnosis of secondary ICH and prediction of hematoma growth using the spot sign in primary ICH, but CTA also involves possible risks of acute kidney injury (AKI) and adverse reactions. The purpose of this study was to evaluate the benefits and risks of CTA. A total of 1423 consecutive adult patients diagnosed with ICH who wer...

ConclusionsDuplex ultrasound has significant limitations in the initial evaluation of patients with suspected SCV thrombosis, with false-negative results in 21% of patients with proven VTOS. This is rarely acknowledged in ultrasound reports, but false-negative ultrasound studies have the potential to delay definitive imaging, thrombolysis, and further treatment for VTOS. Initial false-negative ultrasound results are associated with progressive thrombus extension and a more frequent need for SCV bypass reconstruction at the time of surgical treatment.Graphical Abstract

We present a case of a secondary injury to the femoral artery in a geriatric male patient who sustained a pertrochanteric femoral fracture. Six days after closed fracture reduction and intramedullary femoral nailing, the patient presented with persistent hematocrit level drops, femoral swelling and pain. A computed tomography angiography of the femur revealed a perforation of the profunda femoris artery through the dislocated lesser trochanter fragment, and immediate surgical revision was induced. The patient returned to his pre-injury mobilization level without any peripheral vascular or neurological deficiencies. A liter...

ConclusionSimple methods that measure thrombus permeability are as reliable as complex image processing methods in discriminating recanalizers from non-recanalizers.

In Reply We agree with Popkirov that left atrial volume is a better marker of incident atrial fibrillation than atrial diameter; however, we did not have these data available at all of the sites participating in the New Approach Rivaroxaban Inhibition of Factor Xa in a Global Trial Versus ASA to Prevent Embolism in Embolic Stroke of Undetermined Source (NAVIGATE-ESUS) trial. Recently completed and ongoing studies will help determine if our observation has a clinical role and may provide additional data on left atrial size and function. Once all of these data are available, guidelines committees will likely make recommendat...

To the Editor In a secondary analysis of the New Approach Rivaroxaban Inhibition of Factor Xa in a Global Trial Versus ASA to Prevent Embolism in Embolic Stroke of Undetermined Source trial, Healey and colleagues determined that for patients with embolic stroke of undetermined source and left atrial enlargement rivaroxaban treatment was associated with a 74% reduction in recurrent stroke. The authors suggest that left atrial enlargement could become a new determinant in secondary stroke prevention.

Initial management should include aggressive resuscitation followed by localization of bleeding with nuclear scintigraphy, colonoscopy, or computed tomography (CT) angiography. If bleeding does not resolve spontaneously, expeditious intervention with minimally invasive endoscopic or angiographic methods is necessary with surgical intervention as a last resort.
