Introduction:

popliteal artery injury in a knee arthroscopy has an incidence < 0.01 %. A popliteal pseudoaneurysm is a rare complication. Ultrasound-guided thrombin injection (UGTI) has shown great results in treating femoral artery pseudoaneurysms. This is the reason why this technique is being performed in other locations such as brachial or radial arteries. However, UGTI has barely been reported in popliteal artery.

Case report:

we report the case of a 66 years-old-woman with a popliteal pseudoaneurysm secondary to a knee arthroscopy. It was successfully treated with UGTI, achieving pseudoaneurysm thrombosis, a decreased size, and an improvement of the symptoms with no complications.

Discussion:

endovascular and open surgery are alternative treatments. Open surgery can be helpful when complications occur or hematoma evacuation is required, and endovascular treatment is a good choice in the case of high-risk comorbidities and reduced life expectancy.
