Study design: Case Report
Abstract: Background: Pseudoaneurysm is defined as a hematoma with pulsatile flow inside, which progresses into a pulsatile vascular mass.It subsequently forms an aneurysmal sac whose wall is composed of surrounding tissues and connective tissue adjacent to the hematoma.Unilateral axillofemoral bypass was first described by Louw in 1962 as a treatment for occlusive arterial disease.Extra-anatomic bypass routes should be reserved for patients whose poor general health or specific local conditions preclude the use of a traditional access route or aortofemoral bypass.We must remember the nutritional status of patients, as it influences surgical outcomes.Prosthetic materials, whether Dacron, PTFE, or endoprosthesis, have a useful life, which varies greatly from material to material.We must consider their lifespan and the patient's survival time when deciding which to use. Case Report:The patient developed two pseudoaneurysms secondary to wear of the vascular graft.The first was in the crossover femorofemoral bypass for abdominal aortic aneurysm repair, and the second was for the repair of this pseudoaneurysm itself.This resulted in infection and requiring an extra-anatomical bypass (right unilateral axillofemoral) to resolve the condition.Conclusions: This case report highlights the importance of monitoring patients with arterial disease who undergo vascular prosthesis implantation, and the conventional surgery still plays a critical role in the vascular surgery arsenal for limb and life preservation.An extra-anatomical bypass should remain a last-resort option, as its own nature implies deviation from normal anatomy.Continuous monitoring of these patients is necessary to prevent and identify problems early.
