Abstract
The popliteal artery aneurysm represents the highest incidence among peripherals aneurysms. Since it has significant morbility, it is an important disease. The popliteal artery aneurysm can cause sudden clinicals changes, that if not treated in an appropriate form, will evolue in an desfavorable way, even, with a loss of a limb. In most of cases (nearly 34.8% in the highest serie) they are related with abdominal aorta aneurysm. In addition, conditions like atherosclerosis, mainly factor envolved, cardiovascularies lesions and hypertension are commonly associated. In the present paper a literature review was made, with, evidence, in clinicals, epidemiologics, etiopathogenics of popliteal artery aneurysms. They also enphasas the importance of an early diagnosis and the use of surgery procedures to reach a favorable evolution.

Key words
Aneurysms, popliteal artery, clinicals aspects
