What recent medical procedure increases the incidence of pseudoaneurysms?

Transluminal procedures, particularly those involving catheterization or endovascular interventions, are known to increase the incidence of pseudoaneurysms. During these procedures, a catheter is typically inserted into a blood vessel, and manipulation can sometimes result in an injury to the vessel wall. This injury may lead to the formation of a pseudoaneurysm, where blood leaks out of the vessel but remains contained within surrounding tissues.

The nature of transluminal procedures, such as balloon angioplasty or stenting, inherently carries risks associated with vascular trauma. The access site chosen for the procedure, often in the femoral or radial artery, can be particularly prone to complications.

Understanding the risks associated with such interventions is crucial in vascular technology, as it helps in both the prevention and management of potential complications like pseudoaneurysms. In contrast, options such as open surgery, diagnostic imaging, and physical therapy do not typically involve the same mechanisms of vascular injury that lead to pseudoaneurysm formation.
