A True Aneurysm of Posterior Tibial Artery

Posterior Tibial Artery Aneurysm

“…The exact etiology is unclear; however, many conditions were hypothesized as leading factors: trauma, collagen vascular disease, atherosclerosis, fibromuscular dysplasia, infection and inflammation. The most common clinical presentation is an asymptomatic lump 16 . Complications of PTA aneurysm, such as paresthesia or rupture are rare 17,18 .…”

“…In this case, we could not reveal the cause of the aneurysm formation. Out of reported cases of true PTA aneurysms, eleven cases were idiopathic 12,14,16,[21][22][23][24][25][26] . Four cases were reported secondary to collagen vascular disease including Ehlers-Danlos syndrome and lupus-like syndrome 12,[27][28][29] .…”

Bilateral peroneal artery aneurysms

“…Ligation is also an option in the presence of adequate collateral circulation. 18 Endovascular repair consists of coil embolisation with or without covered stent placement. These methods are good alternative treatments for high risk patients for conventional surgical repair.…”

True Giant Posterior Tibial Artery Aneurysm

“…In the English Literature, few cases of true atherosclerotic PTA aneurysm had previously been reported [1–6]. The indications for treating these lesions are debated, but usually symptomatic aneurysms such as asymptomatic large aneurysms or those with laminated thrombus should be treated [2, 6].…”

“…The surgical repair is typically achieved with autogenous vein bypass grafting; artery direct suture is described with good success for focal lesions. When there is an adequate collateral circulation, artery ligation can be a second option [1, 5, 6]. The endovascular treatment (coil embolization, thrombin glue injection, covered stent) is a good alternative to surgery and is preferred in case with high-risk patients [3].…”
