True tibial artery aneurysms: Case report and literature review

Abstract

True tibial artery aneurysms are rare lesions. They may manifest themselves clinically either as a painful leg mass or as evidence of ischemic changes in the foot. Asymptomatic lesions may be found incidentally during arteriography. The need for surgical intervention should be individualized depending on the presentation; the type of surgical intervention is based on coexistent tibial artery anatomy. The present report describes a patient with a true tibial artery aneurysm. Clinical presentation, radiographic findings, and surgical management are described.

Urgent Endovascular Repair of an Anterior Tibial Artery Aneurysm: Case Report and Literature Review

“…True ATAAs are rare; a search of the available literature revealed 20 cases spanning from 1944 to 2020 (Table 1). 1 -19 The average age of reported patients at the time of intervention was 52 with a range of 28 to 86. Sixty-five percent (n = 13) were male and 35% (n = 7) were female.…”

“…Pain and swelling (35%; n = 7) or the presence of an expanding mass (35%; n = 7) 1 -3,10,13,14,17 were the most common symptoms at the time of surgery. Progression of aneurysm expansion ranged from a few days to 1 year.…”

“…Nineteen of the patients were repaired by an open approach: 7 received arterial ligation (37%), 1 -4,7,11,13 4 ligation and resection (21%), 9,10,14,19 4 required autologous bypass (21%), 8,15,18 3 primary repair (16%), 6,17 and 1 coil embolization and ligation (5%). 5 While each approach has its advantages, reconstruction with saphenous interposition is considered superior by many, especially in the setting of flow-limiting peripheral vascular disease.…”

Posterior Tibial Artery Aneurysm

“…True tibial artery aneurysms are considered rare 11 . Two-thirds have involved the PTA, the remainder has been found in the anterior tibial arteries 12 .…”

“…Most of the true aneurysms are associated with an inflammatory or infectious process 14 . Two cases of bilateral true aneurysms of the PTA were reported 11,15 . The coincidence of idiopathic PTA aneurysm with other aneurysms is unique and was reported only in one case 15 .…”
