What does the ICA supply?
The Brain
What does ECA supply?
face & neck
What does it mean if your color doppler is aliasing when scanning the CCA?
The scale is too low
What is the name of this branch off the Aortic Arch?
Left CCA
What is the name of the artery that is tapped during a temporal tap?
Hint- Off the ECA
Superficial Temporal Artery
What does the Lingual Artery off the ECA supply?
The Tongue
What is the correct probe placement to doppler the vert?
What is the name of this branch off the Subclavian Artery?
Hint-3rd branch
Costocervical Trunk
What Vertebral level does the CCA bifurcate at?
C4
What does Ophthalmic Artery off the ICA supply?
Eyes
Why does the CCA have a low resistive wave form?
It supplies the ICA (80%) which supplies the brain
What is the name of this part of the CCA?
The Bulb
Why is the velocity of the ICA (60-100 cm/s) higher than the velocity of the ECA (40-75 cm/s)?
Low-Resistance, supplies brain which has a high oxygen demand
What is the smallest branch of the ECA?
Hint- Supplies Pharynx, ear & neck muscles
Ascending Pharyngeal Artery
When scanning the CCA what direction will your transducer go if you follow it into the ICA and continue up the neck?
Hint- Looking for directional terms
Posterior & Lateral
What is the name of this segment of the ICA?
Hint- 4th segment
Cavernous segment
What does AIDET stand for?
Acknowledge, Introduce, Duration, Explanation, Thank you
Put the 8 branches in order (2x Points!!!!)
Occipital, Posterior Auricular, Lingual, Facial, Maxillary, Superficial Temporal, Superior Thyroid, Ascending Pharyngeal
Superior Thyroid, Ascending Pharyngeal, Lingual, Facial, Occipital, Posterior Auricular, Maxillary, Superficial Temporal
What is the purpose of the Temporal Tap?
To help differentiate between the ICA and ECA by disturbing the ECA waveform but not the ICA waveform.
What is the name of this artery that comes off the ECA?
Posterior Auricular Artery
