Left popliteal aneurysm

Abstract

Popliteal artery aneurysm is the main peripheral aneurysm and the second in frequency after abdominal aortic aneurysm. Its incidence is unknown. It has a characteristic presentation pattern that corresponds to male people, over 65 years of age, with multiple comorbidities, where arterial hypertension represents the most frequent. The definition of aneurysm corresponds to a dilation of 50% of the diameter of the vessel, in the case of the popliteal artery, greater than 1.5 cm. 50% of popliteal aneurysms are asymptomatic, the rest have ischemic symptoms (thrombosis, peripheral embolisms), compression and rupture. Treatment is surgical: conventional (medial-posterior pathways) and endovascular. The objective of the article was to present this case due to the infrequency of the unilateral popliteal artery aneurysm. This is a 62-year-old male patient, with localized volume increase at the level of the left popliteal fossa with heartbeat and expansion on palpation, approximate transverse diameter of 3 cm and longitudinal diameter of 4 cm, presence of systolic murmur at auscultation with ultrasound and arteriographic diagnosis of aneurysm of the left popliteal artery. The patient's evolution was satisfactory and he remains under medical follow-up to evaluate the permeability of the synthetic graft.
