What is a pseudoaneurysm? Dilation of an artery with all three layers intact Dilation of an artery contained in a fibrous capsule Defect of all arterial layers that fails to heal Defect of all arterial layers that closes only after surgical intervention
What is the clinical presentation associated with a pseudoaneurysm? Palpable mass and soft tissue swelling Pain and visible bruising Ischemia and high blood pressure Compartment syndrome and cellulitis
What is the gold standard for diagnosis of a pseudoaneurysm? Duplex sonography CTA Angiography MRI
What is the classic sonographic appearance of a pseudoaneurysm? Yin-yang sign Telescoping sign Cinnamon bun sign Double barrel sign
When initial treatment attempts fail, what is a treatment technique that can be used? Sonography-guided compression Thrombin injection Continue to monitor for resolution Endovascular coil embolization
What are the most common causes of a pseudoaneurysm in the foot and ankle? Fracture and vessel compression Ankle strain or sprain Arterial catheterization and trauma Malignant or benign masses
