Case report: rupture of popliteal artery aneurysm

Abstract

An 83-year-old female patient with a history of prior endovascular treatment to repair an abdominal aortic aneurysm presented with intense pain and edema in the left leg, with hyperemia and localized temperature increase. Doppler ultrasonography revealed a voluminous aneurysm of the popliteal artery with a contained rupture, and hematoma involving the popliteal fossa and the medial and anterior surfaces of the knee causing compression of the popliteal vein. Endovascular repair was accomplished with covered stents and the rupture was confirmed. during the procedure The aneurysm was excluded and the signs and symptoms it had caused resolved completely, but during the postoperative period the patient developed sepsis of pulmonary origin and died.

“…The popliteal artery is the most common site of peripheral aneurysms (70 to 85%). 1,3 Among people who have a PAA, there is also a high prevalence of aneurysms at other sites in the body, such as the contralateral popliteal artery (40 to 68.9%) and the abdominal aorta (30 to 60%). [3][4][5]12,13 Development of PAA is related to atherosclerotic disease and occurs in individuals with well-defined characteristics: male patients, from the 7th decade of life onwards.…”

“…Symptoms include pallor, absent distal pulses, and sudden loss of strength in the limb. 1 Aneurysmal rupture is a rare complication in PAAs (0.5 to 7%). 1 Acute PAA presentations should be treated as medical emergencies.…”

“…1 Aneurysmal rupture is a rare complication in PAAs (0.5 to 7%). 1 Acute PAA presentations should be treated as medical emergencies. Prompt resolution is necessary because limb viability is threatened and because of the potential threat to the patient's life.…”

“…Popliteal artery aneurysm (PAA) is the most common type of peripheral aneurysm 1,2 and constitutes a threat to the limb involved and, in more severe cases, to the life of the patient. PAAs may be asymptomatic 3 or may manifest acutely as medical emergencies.…”

“…Thromboembolic phenomena are the most common causes of emergencies and ruptures are rarer. [2][3][4][5] Etiology is primarily linked to atherosclerosis, 1 but can also be related to inflammatory states, infectious conditions, and connective tissue diseases. 6 Prevalence is higher among men and the elderly, 2 and the primary risk factors are arterial hypertension and smoking.…”
