Vascular Entrance Exam 2 Flashcards
The name of the Denali program offered by BD to track patients for future retrievals is
Reach
What is the gold standard for DVT treatment?
Anticoagulation
What are Denali filters contraindications?
a. Septic patients
b. Pregnant patient when Xray is harmful (early gestation)
c. Patients with unknown sensitivity to nickel-titanium alloys
d. Patients with an IVC larger than 28mm
How do we recommend deploying the Denali?
Pin and Pull; pin handle and pull Tuohy in one motion
Ultra non-compliant balloons have a growth rate of?
1% or less
The Geoalign Marker system offers what % reduction in flouro time?
27%
Compare Conquest to Conquest 40?
Conquest 40 has a tapered tip and higher atms, conquest 40 offers different sizes
Which balloon is ultra-non-compliant and has checker flex points?
Dorado, checkerflex points increase flexibility in tortuous anatomy.
What is successful PTA characterized by?
a. Less than 30% residual stenosis
b. Fully effaced balloon
c. Thrill is restored
d. Patient can resume success dialysis
What catheter designs do our balloons offer?
a. Coaxial (dual lumen) for push-ability
b. Triaxial (triple lumen) trackability
What is Barotrauma?
Over dilation of a balloon causing damage to healthy
Tissue
What is the difference between Atlas and Atlas Gold:
Atlas Gold has shorter 21mm shoulders which minimizes vessel straightening and barotrauma (Atlas has 37mm shoulders)
b. Atlas Gold has enhanced tapered tip improving trackability
Does a 12mm conquest and a 12mm Atlas require a 8Fr sheath?
No, a 12mm Atlas can go through a 7Fr sheath. (and the 14mm Atlas does as well)
T/F: Glidewires should be twice the length of the device in use?
True
The most common cause of stenosis is?
intimal hyerplasia
What is Intimal hyperplasia?
Scar tissue forming in the lumen of the vessel due to trauma, increased flow (turbulent).
How many anastomoses does AV grafts have?
2; venous and arterial
How many anastomoses do AV fistula’s have?
1; arterial. AVF’s have a juxta anastomosis which is located 1-2cm before the arterial anastomosis.
