Abstract
The following questions for SVU-CME examination are based on the article entitled “High Grade Stenosis of a Traumatic Brachiocephalic Pseudoaneurysm and the Change in Cerebral Blood Flow Assessed with Transcranial Doppler Ultrasound.”
Both true/false and multiple-choice questions are included. There is only one (1) correct answer for the multiple-choice test items. Answer all the questions as listed below. One-half (1/2) CME credit will be awarded for successful completion of this test with a grade of 80% or more.
A 35-year-old female presented with a traumatic blunt force injury to her brachiocephalic artery. A transcranial Doppler was performed which demonstrated hesitant waveforms in the right middle cerebral and vertebral arteries secondary to a distal hemodynamically significant stenosis.
True False
What modality can detect active embolization signals?
Magnetic resonance imaging (MRI) Computed Tomography (CT) Transcranial Doppler (TCD) Digital subtraction angiography (DSA)
The right vertebral artery demonstrated a hesitant waveform with a mid-systolic flow deceleration also known as the ________sign.
HIT Bunny MES Biffl
Serial transcranial Doppler examinations can be performed to assess the effectiveness of an anticoagulant.
True False
Figure 5C is a magnetic resonance image taken five days after the injury demonstrating interrupted blood flow to the cerebrovascular circulation causing which of the following?
A high-intensity transient signal A unidirectional, short, transient infarct A micro embolic signal Multifocal watershed infarcts
Heparin was started after the patient’s injury. The next day she presented with bleeding in her chest. The most appropriate next clinical step is:
Surgical intervention Adjust the heparin dosage Cauterize the chest wall Stop the heparin
Instructions: CME tests are offered only online at www.svu.org. SVU Members can complete the tests and earn CME for free. Nonmembers will be charged $40 per CME test taken. All exams for SVU CME must be completed by May 31, 2024.
