Question

Question 36 (1 point) Which two amongst the five following statements are wrong? 1) A stent can be used to treat restenosis 2) A lysis of the lumen by rotational ablation is desirable before inserting a stent 3) Catheter with very large outer diameter must be used in angioplasty 4) Devices such as expandable balloons can be used in angioplasty before inserting a stent 5) XeCl excimer laser has never been used clinically to remove atherosclerotic plaque in angioplasty. 1) and 2) 2) and 3) 3) and 4) 3) and 5) 1) and 4)

Answer 1

The most commonly used laser for clinically removing atherosclerotic plaque in aginoplasty is xenon chloride (XeCl).

Therefore option (5) is not true.

Also option 3 is wrong because balloon catheters have several limitations that include a slightly larger diameter than the rapid-exchange (monorail) catheters and the need for additional personnel to help with long guidewire catheter exchanges.

and large diameter Catheter is usually avoided.

So answer is Option (3) and (5) are wrong
