anticoagulant therapy before and after procedure - answer✔✔Ascending venography
Contraindications for ultrasound guided compression therapy for a pseudoaneurysm: -
answer✔✔- patient unable to tolerate the procedure due to pain
-Infection as a puncture site and surrounding tissues
-diameter greater than 4 cm
-Stalk diameter greater than 5 mm
-Present for more than one month

List the advantage of intraoperative vascular ultrasound, compared to intraoperative angiography
- answer✔✔Ultrasound does not require a vessel puncture to obtain flow information
At _____________ post injection, ______________ should be performed to determine the
success of a thrombin injection for pseudoaneurysm treatment - answer✔✔20 mins ; color

Sonographic appearance of a transjugular intrahepatic portosystemic shunt TIPS -
answer✔✔Strongly reflective, curved structure connecting the right portal vein in right hepatic
vein
A patient is undergoing balloon angioplasty of the left common femoral artery. The physician
just completed the first expansion of the balloon and asks you to check the flow with Doppler.
Where is the preferred location to evaluate flow? - answer✔✔Dorsalis, pedis, or posterior tibial
artery (most important to evaluate flow in the most distal areas to evaluate improvement in
overall perfusion of the leg)
A patient presents for a follow up exam after radiofrequency ablation of the GSV. What is the
purpose of the exam? - answer✔✔To confirm the contraction of the GSV and absence of
thrombus in the deep system

harvesting, but does not indicate which vessel he plans to use. Which lane should you evaluate
because it is most commonly used for bypass? - answer✔✔Cephalic vein
Radiofrequency venous ablation requires ____________ - answer✔✔Sterile technique

answer✔✔evaluate the venous system in the right arm
A common complication of cardiac catheterization is the formation of: -
answer✔✔Pseudoaneurysm
During cardiac catheterization, the superficial femoral artery is punctured by the catheter as it
enters the arterial system. Once the catheter is removed, there is a risk that blood will escape the
artery into the surrounding tissues to form a __________ - answer✔✔Pseudoaneurysm
A patient presents for a follow up for the TIPS located between the right portal vein and right
hepatic vein. The chart indicates an abnormal bruit and stenosis is suspected. Where should you

answer✔✔Hepatic vein anastomosis
_________________ is the most common side of stenosis in a TIPS - answer✔✔Hepatic vein
anastomosis
