Percutaneous Stent-Graft Repair of Anastomotic Pseudoaneurysms following Vascular Bypass Procedures: A Report of Two Cases
Figure 1
(a) Coronal CT scan demonstrates a large aPSA near the proximal end of an axillofemoral bypass graft (arrows). The distal end of the bypass is noted by the open arrow. (b) A reconstructed para-axial image from the CT scan better shows the relationship between the aPSA and proximal bypass anastomosis. Long arrow corresponds with the axillary artery with the open arrow pointed at the axillary vein. A short landing zone for stent graft exclusion is noted at the neck of the aPSA (short arrow). (c) Angiogram shows filling of a large aPSA located 2 cm from the subclavian artery anastomosis. A marker catheter has been introduced from the brachial access and a wire traverses the graft and extends into the proximal subclavian artery via a direct distal bypass puncture. (d) Successful complete exclusion of PSA is seen on completion arteriography with preserved flow through both the native subclavian (short arrow) and brachial artery as well as the axillobifemoral graft (long arrow).
