Spontaneous tibioperoneal trunk and anterior tibial artery pseudoaneurysms

Abstract

Aneurysms of the tibioperoneal trunk and anterior tibial artery are extremely rare. There are only a few case reports of this entity, for which the majority are secondary to prior trauma or bacteremia and endocarditis. We describe a case of spontaneous pseudoaneurysms of the right anterior tibial artery and tibioperoneal trunk. The pseudoaneurysms were thrombosed on follow-up computed tomography angiography and the patient has been asymptomatic. The patient is being treated conservatively and remains asymptomatic at 1 year of follow-up.

Successful endovascular isolation of a huge true anterior tibial artery aneurysm by the bi‐directional approach in a young patient

“…Most cases of crural artery aneurysmal degeneration result from trauma, iatrogenic injuries, or infection, and the consequence is usually a pseudoaneurysm . Because of its rarity, the incidence has not been described to date .…”

“…ATAAs can be asymptomatic or present with swelling, pain, rupture, embolism, thrombosis, bruising, or complications such as tibial nerve palsy due to compression . They can be diagnosed by performing non‐invasive ultrasonography, enhanced CT, or MRI, although digital subtraction angiography has been traditionally accepted to be the gold standard …”

Three-Year Delayed Presentation of Femoral Pseudoaneurysm after Penetrating Limb Trauma

“…9,10 Rarely, lower limb pseudoaneurysms have also been known to develop spontaneously with 1 case involving the right anterior tibial artery and tibioperoneal trunk successfully managed conservatively. 11 Promise has been demonstrated for endovascular management of iatrogenic pseudoaneurysms with 1 retrospective review revealing successful elimination of 4 cases of pseudoaneurysm. 12 Furthermore, in a 12-year retrospective review of 8 pseudoaneurysms, of both iatrogenic and traumatic etiology, primary clinical success was obtained in 84% of patients with no long-term embolization-related complications.…”

A case report of an anterior tibial artery pseudo-aneurysm open surgical management: A rare complication post total knee arthroplasty

“…While this form of pseudo aneurysm has been reported to thrombose off spontaneously [8], vascular intervention rather than surveillance remains the favored approach in view of the potential catastrophic complications. However, due to the rarity of this condition, a variety of interventions have been reported in the English medical literature with probably no compelling evidence that favors one modality over the others.…”
