Recurrent pseudoaneurysm at the level of arteriovenous fistula in the left arm

Abstract:

Pseudoaneurysm is damage to the arterial wall, contained by the surrounding hematoma and neighboring structures, with turbulent blood flow, which maintains communication with the lumen of the affected vessel. The present study describes a 57-year-old male patient who was admitted with a diagnosis of left cephalic humeral arteriovenous fistula pseudoaneurysm. The false aneurysm was excised, and a new fistula was created with a vascular prosthesis. The patient was readmitted in the fifth month with a giant pulsatile mass at the surgical site. Surgical exploration was performed, excision of the recurrent pseudoaneurysm and a new left humerus-basilic fistula with saphenous vein. He is progressing favorably, performing dialysis two years after the last surgery without complications.
