Abstract

A 57-year-old man with chronic kidney disease stage 5 presented for ambulatory evaluation of his arteriovenous fistula. He underwent rheolytic thrombectomy with tissue plasminogen activator infusion, angioplasty, and brachial artery stenting under local sedation. His immediate postoperative course was complicated by hypotension, cardiac dysrhythmias and hyperkalemia requiring emergent hemodialysis, due to severe intravascular hemolysis. This case illustrates that mechanical thrombectomy can cause clinically significant intravascular hemolysis, thus careful postoperative monitoring is recommended.
