Pseudoaneurysms in Peripheral Vasculature Following a Percutaneous Intervention, Different Diagnostic Approaches: Case Reports

Pseudoaneurysm is defined as a vascular anomaly generated by the interruption of the arterial wall, which conditions accumulation and persistent confinement of blood. The incidence of pseudoaneurysm ranges between 0.2%-0.5% in diagnostic interventional techniques and up to 6% in therapeutic techniques, however, despite its low incidence, complications are potentially severe. We present 3 cases of pseudoaneurysm in the peripheral vasculature after percutaneous interventions, as well as the description of the diagnostic challenge and the assessment by the different imaging methods.

This case report article shows the diagnostic approach through the different imaging methods, as well as a brief review of the subject with a focus on the role of the interventional radiologist.
