Ruptured infected popliteal artery aneurysm treated with endovascular therapy: A case report.

An 86-year-old woman was admitted for a ruptured popliteal artery aneurysm (rPAA, 26 × 28 mm). Due to the patient's age and comorbidities, emergency endovascular repair was performed. After the failed antegrade guidewire crossing, a retrograde approach from the anterior tibial artery and snaring was performed for lesion crossing, and stentgraft (5 × 50 mm) was deployed from antegrade fashion. At the 14-month follow-up, computed tomography angiogram demonstrated stentgraft patency and reduced aneurysmal size. Although open surgery remains the first-line treatment for infected rPAA, our approach adds to the evidence and can be applied to emergency cases or high-risk surgical patients.
