What is a common complication associated with the use of a Rotoblador?

1. Distal embolization

2. Cardiac arrhythmias

3. Pneumothorax

4. Hyperkalemia

The correct answer is: Distal embolization

Distal embolization is indeed a well-known complication associated with the use of a Rotoblador. The Rotoblador, or rotational atherectomy device, is used in interventional cardiology to treat coronary artery disease by breaking up calcified plaques to improve blood flow. As the device grinds away the calcified lesions, small particles can be dislodged and migrate downstream in the bloodstream. This process can lead to distal embolization, where the dislodged material flows into smaller arterial branches, potentially causing blockages and ischemia in those areas. In the context of the other choices, cardiac arrhythmias can occur in various cardiac procedures, but they are not specifically tied to the use of a Rotoblador. Similarly, while pneumothorax is a possible complication during procedures involving access to the chest or lung, it is not relevant to the Rotoblador's function. Hyperkalemia refers to elevated potassium levels in the blood, which is unrelated to the mechanical interactions of the Rotoblador during its procedure. Therefore, distal embolization stands out as the most pertinent complication when discussing the use of a Rotoblador.
