Large non-anastomotic false aneurysm on dacron aortobifemoral prosthesis solved by endovascular exclusion.
Aortic and iliac pseudo-aneurysms are infrequent but challenging complications after open surgical graft reconstructions, mostly having para-anastomotic localisations. The true corporeal peri-prosthetic false aneurysms are, up until now, very rarely documented presentations. We report the clinical case of an 8.8 cm diameter non-anastomotic and aseptic pseudo-aneurysm developed on aorto-bifemoral Dacron prosthesis in a symptomatic and high surgical risk patient. Considering the clinical presentation and the anatomical features, a chronic tear of the posterior prosthetic wall by prominent aortic remnant calcifications was evoked as the possible aetiology. An endovascular exclusion, using a tapered aorto-uni-iliac endograft coupled to a femoro-femoral bypass revascularisation, was technically successful. Despite scarce published clinical data focusing on the optimal treatment dedicated to this category of false aneurysm, this approach is thought to be beneficial in selected cases of high-risk surgical patients.
