This document discusses arterial pseudoaneurysms, including their causes, diagnosis, and treatment options. It notes that the prevalence of pseudoaneurysms has increased with more surgical and arteriographic procedures. Diagnosis can be done through imaging modalities like ultrasound, CT, and angiography. Treatment has increasingly involved minimally invasive interventional radiology techniques like embolization and stent placement, rather than surgery, due to lower risks. The document also presents six case studies of pseudoaneurysm patients treated with various interventional radiology procedures.
