RCIS Vascular Access and Closure Devices 1 — Questions and Answers
Question 1: What is the standard landmark for femoral arterial access using the modified Seldinger technique?
- 2 cm below the inguinal ligament
- 1 cm below the inguinal ligament
- Over the femoral head at the mid-inguinal point (Correct answer)
- 2 cm above the inguinal ligament
Correct answer: Over the femoral head at the mid-inguinal point
The optimal femoral arterial puncture site is over the femoral head at the mid-inguinal point to allow effective manual compression and reduce hematoma risk.
Question 2: Which complication is most associated with a high femoral arterial puncture above the inguinal ligament?
- Arteriovenous fistula
- Retroperitoneal hematoma (Correct answer)
- Pseudoaneurysm
- Femoral nerve injury
Correct answer: Retroperitoneal hematoma
High femoral puncture above the inguinal ligament can lead to retroperitoneal hematoma because the vessel cannot be compressed against the femoral head.
Question 3: What is the primary advantage of transradial access over transfemoral access for cardiac catheterization?
- Larger sheath sizes can be used
- Reduced vascular access site complications and earlier ambulation (Correct answer)
- Better visualization of the coronary ostia
- Easier access to the right coronary artery
Correct answer: Reduced vascular access site complications and earlier ambulation
Transradial access significantly reduces access site bleeding complications and allows patients to ambulate immediately after the procedure.
Question 4: The Allen test is performed before radial artery access primarily to assess:
- Brachial artery patency
- Collateral ulnar circulation to the hand (Correct answer)
- Radial artery stenosis
- Palmar arch anatomy
Correct answer: Collateral ulnar circulation to the hand
The Allen test evaluates ulnar collateral blood flow to ensure adequate hand perfusion if radial artery occlusion occurs post-procedure.
Question 5: Which vascular closure device uses a collagen plug deployed into the arteriotomy site to achieve hemostasis?
- Perclose ProGlide
- AngioSeal (Correct answer)
- StarClose
- MYNX
Correct answer: AngioSeal
AngioSeal uses an intravascular anchor and collagen plug system to mechanically seal the arteriotomy at the femoral access site.
Question 6: What minimum sheath size is typically required to deploy most vascular closure devices at the femoral access site?
- 4 French
- 5 French
- 6 French (Correct answer)
- 8 French
Correct answer: 6 French
Most vascular closure devices are designed for 6 French or larger arteriotomies to ensure adequate deployment and effective sealing.
