Abstract

The term Popliteal aneurysm was coined as a cut perpendicular to the long axis of the vessel; greater than 15 mm or present loss of parallelism of the vessel walls with a diameter that exceeds 1.5 times the expected normal diameter. It is generally asymptomatic, and in a third of cases it can present as acute ischemia. A case of a 73-year-old male patient, panvascular and diabetic, without adherence to antihypertensive and hypoglycemic treatments, who presented a right popliteal aneurysm of several months of evolution, which began with sudden pain at rest in the lower limb, is developed right, at the infrapatelar level, associated with pallor and coldness, with the absence of infrapatellar pulses. Doppler ultrasound of the lower limb shows a 65- mm popliteal aneurysm with mural thrombi. In the surgical intervention, repair of the aneurysm is performed, femoro-popliteal bypass with PTFE prosthesis.
