• Incidence 0.2 to 25%
• Likely underdiagnosed
• Incidence: femoral > iliac > aortic
• At diagnosis 8-40% are ruptured
• Mortality ranges from 61-67%
• Interval imaging at 3-5 years post-op

• Axillary cutdown for axillary artery exposure
• Hemashield graft anastomosis for sheath access
• 3 x 7Fr sheaths in separate accesses

• High mortality rate
• Risk of pseudoaneurysm increases over time
• Inflammatory rind, difficult reoperative field
• Stent grafts also with complication risks: endoleaks,
thrombosis, migration, rupture, infections
• Serial post-operative imaging
• Endovascular approach is an excellent option for
pseudoaneurysm exclusion
