Fogarty’s catheter is used for –
**Core Concept**
Fogarty's catheter is a type of balloon catheter used in vascular surgery for embolectomy, specifically to remove thrombi (blood clots) from arteries. It works by inflating a balloon within the catheter, which is then inserted into the blocked artery to capture the clot.
**Why the Correct Answer is Right**
The Fogarty catheter is designed to navigate through the narrowed or blocked artery and grasp the thrombus (blood clot) with its balloon. Once the balloon is inflated, the catheter is slowly pulled back, removing the clot from the artery. This procedure is typically used in emergency situations, such as acute limb ischemia, to restore blood flow to the affected limb.
**Why Each Wrong Option is Incorrect**
**Option A:** This is incorrect because Fogarty's catheter is not used for coronary angioplasty. While it is a type of balloon catheter, its primary function is for embolectomy, not angioplasty.
**Option B:** This is incorrect because Fogarty's catheter is not used for dialysis access creation. Although it is a type of catheter, its design and function are specific to vascular surgery, not dialysis access.
**Option C:** This is incorrect because Fogarty's catheter is not used for central line placement. While it is a type of catheter, its primary function is for embolectomy, not central line placement.
**Clinical Pearl / High-Yield Fact**
Fogarty's catheter is a crucial tool in vascular surgery for removing blood clots from arteries. It is essential to understand its mechanism and application to manage acute limb ischemia effectively.
**Correct Answer: C. Fogarty's catheter is used for embolectomy.**
