What is the guidewire of choice used in percutaneous procedures?
J-Tip .035’’
The J-Tip guidewire is commonly used for navigating tortuous vessels.
What type of guidewire is designed for tortuous vessels?
Wholey Wire
Wholey wires are specifically designed to navigate complex vascular pathways.
What is a characteristic feature of hydrophilic coated guidewires?
Glidewire
Glidewires have a hydrophilic coating that facilitates smoother navigation.
What is the purpose of pressure wires in interventional procedures?
Therapeutic
Pressure wires are used to measure pressure gradients across lesions.
What are the components of guide wires’ construction?
Inner (Mandrel) Core Wire, Wrapped Outer Wire
These components contribute to the strength and flexibility of the guide wire.
What materials are commonly used in the construction of guide wires?
Nitinol, Platinum, Gold
These materials provide different properties such as flexibility and radiopacity.
What is the standard measurement unit for catheter sizes?
French
French size indicates the diameter of the catheter.
Name two types of therapeutic devices used in percutaneous procedures.
Balloons, Stents
These devices are essential for treating vascular lesions.
What is the primary indication for Percutaneous Transluminal Angioplasty (PTA)?
Stenosis
PTA is primarily indicated for treating narrowed arteries.
What type of balloons are used in percutaneous procedures?
Over the Wire, Single-Operator Exchange, Fixed-Wire, Perfusion Balloons, Cutting Balloons
These balloon types serve different purposes in vascular interventions.
What are the two classifications of balloon compliance?
Compliant, Non-Compliant
These classifications refer to how balloons expand under pressure.
What are the types of stents available?
Self-Expanding, Balloon-Expanding, Passive-Coated, Active Coated (Drug-Eluting), Covered Stents (Stent-Graft)
Different types of stents are used depending on the clinical scenario.
What is atherectomy?
Alternative to PTA, Physical Removal of Plaque
Atherectomy involves removing plaque from the arterial walls.
What are the types of mechanical thrombectomy devices?
Pressurized Saline, Rotator, Oscillating, Manual
These devices physically remove thrombus from coronary arteries.
What are the methods of distal protection device placement?
Distal Balloon Occlusion, Distal Filter, Proximal Occlusion/Flow-Reversal
These methods help prevent embolization during procedures.
What is the purpose of brachytherapy in vascular procedures?
Indication
Brachytherapy is used to deliver localized radiation to prevent restenosis.
