What type of intravascular catheter has a balloon tip and is placed in a vein?

The correct answer is a Fogarty catheter. This type of intravascular catheter is specifically designed with a balloon tip, which allows for the occlusion of blood vessels for various medical procedures. The balloon can be inflated to help capture or remove obstructions within the vessel, such as thrombus during embolectomy procedures. It is placed in a vein to facilitate this process, making it an essential tool in vascular surgery.

In contrast, the other types of catheters mentioned serve different purposes. A pick catheter, for example, is typically used for long-term access to patients' veins, providing an ongoing route for medications or fluids but does not have a balloon tip. A central line is a broader category of catheters such as those used for administering medications, fluids, and for monitoring hemodynamic pressures; these may also not feature a balloon tip. A guide wire isused to assist in the placement of catheters during procedures and does not serve the function of occlusion or aspiration like the Fogarty catheter does.
