ARRT VASCULAR INTERVENTIONAL MOCK EXAM 2025 UPDATED
EXAM WITH MOST TESTED QUESTIONS AND ANSWERS | GRADED A+ |
ASSURED SUCCESS WITH DETAILED RATIONALES
1. Which aortic arch variation has the highest incidence?
A) Coarctation
B) Duplicated arch
C) Common origin innominate and left common carotid arteries (Correct Answer)
D) Left vertebral arising from aorta
Rationale: The bovine arch (common origin) occurs in ~15-25% of population, making it the most
common normal variant.
2. Which artery primarily supplies neck/face/scalp structures?
A) Internal carotid
B) Cervical branches of common carotid
C) Vertebral arteries
D) External carotid arteries (Correct Answer)
Rationale: The external carotid has 8 branches (e.g., facial, superficial temporal) supplying extracranial
structures.
3. Which coil embolization guideline is LEAST appropriate?
A) Match coil wire diameter to catheter lumen
B) Final coil diameter should match target vessel exactly (Correct Answer)
C) Gentle forward pressure helps packing
D) Platinum coils are softer/more visible than steel
Rationale: Coils should be 10-20% larger than the target vessel to ensure stable positioning.
4. What device delivers contrast boluses during angiography?
A) Catheter (Correct Answer)
B) Port
C) Stent
D) Line
Rationale: Catheters (e.g., pigtail, selective) are designed for precise contrast administration.
5. Preferred access when thoracic veins/IVC are occluded?
,ESTUDYR
A) Subclavian vein
B) Upper extremity veins
C) Transhepatic access (Correct Answer)
D) Translumbar access
Rationale: Transhepatic avoids occluded veins; translumbar is higher-risk for bleeding.
6. Which embolic agent comes as sterile bricks/powder and absorbs in 4-6 weeks?
A) Autologous clot
B) Vascular plug
C) Gelfoam (Correct Answer)
D) Polyvinyl alcohol (PVA)
Rationale: Gelfoam is compressible, temporary, and absorbed within weeks.
7. PICC line placement guidelines EXCLUDE:
A) Surgical arm prep
B) Basilic/cephalic vein preferred
C) Micropuncture access
D) Catheter tip in low left atrium (Correct Answer)
Rationale: PICC tips belong in the SVC/RA junction, not the left atrium.
8. Which guidewire type causes the most dissections?
A) Terumo (glidewire)
B) Rosen (J-tip)
C) Straight (Correct Answer)
D) 3J wire
Rationale: Straight wires lack protective curves, increasing intimal injury risk.
9. A digital image's arrangement of pixels is called a(n):
A) Image matrix (Correct Answer)
B) Dynamic range
C) Digital subtraction
D) Data range
Rationale: The matrix (e.g., 1024×1024) defines pixel rows/columns.
Continued Questions (10-40)
,ESTUDYR
10. The "bovine arch" refers to:
A) Aortic coarctation
B) Left CCA originating from innominate artery (Correct Answer)
C) Right-sided aortic arch
D) Aberrant right subclavian
Rationale: This normal variant is seen in ~13% of people.
11. Which vessel supplies the Circle of Willis?
A) External carotid
B) Internal carotid (Correct Answer)
C) Vertebral
D) Thyrocervical trunk
Rationale: The ICA and vertebrals form the Circle of Willis.
12. For vessel occlusion >6 weeks, use:
A) Gelfoam
B) PVA particles (Correct Answer)
C) Autologous clot
D) Contrast agent
Rationale: PVA causes permanent occlusion vs. temporary Gelfoam.
13. Most common PICC complication:
A) Infection
B) Thrombosis (Correct Answer)
C) Air embolism
D) Nerve injury
Rationale: DVT occurs in 4-15% of PICCs.
14. Best wire for crossing tight stenoses:
A) Rosen
B) Terumo glidewire (Correct Answer)
C) Straight wire
D) Amplatz
Rationale: Hydrophilic glidewires navigate difficult lesions.
15. Pixel size depends on:
, ESTUDYR
A) Patient age
B) Matrix size and FOV (Correct Answer)
C) Contrast dose
D) Catheter type
Rationale: Pixel size = FOV/matrix (e.g., 30cm/512 = 0.58mm).
16. The most common aortic arch branching pattern is:
A) Bovine arch
B) Normal 3-vessel arch (Correct Answer)
C) Aberrant right subclavian
D) Left vertebral origin from aorta
Rationale: ~70% of people have the standard branching: innominate, left CCA, left subclavian.
17. Which vessel supplies the posterior cerebral circulation?
A) External carotid
B) Internal carotid
C) Vertebrobasilar system (Correct Answer)
D) Thyrocervical trunk
Rationale: The vertebral arteries join to form the basilar artery, supplying the posterior fossa.
18. For permanent vessel occlusion, which agent is preferred?
A) Gelfoam
B) Coils or vascular plugs (Correct Answer)
C) Autologous clot
D) Contrast medium
Rationale: Metallic coils/plugs provide permanent occlusion vs temporary agents like Gelfoam.
19. The safest initial access for difficult IVC cases is:
A) Femoral vein
B) Right internal jugular vein (Correct Answer)
C) Left subclavian vein
D) Transhepatic approach
Rationale: Right IJ offers the most direct path to the SVC/IVC with fewer valves.
20. Which statement about Gelfoam is FALSE?
A) It's absorbable
B) Can be cut into pledgets
