Venous Thromboembolism (VTE) is a major public health concern, affecting approximately 900,000 people annually in the United States. In rare cases, a Patent Foramen Ovale (PFO) may allow a venous thrombus to cross into the arterial circulation, causing a paradoxical embolism. This case report presents a 46-year-old male who developed left renal artery stenosis after a paradoxical embolism, likely triggered by a prolonged flight and binge alcohol consumption. The patient was found to have a moderate-sized PFO and renal infarction, confirmed by imaging studies. Despite initial anticoagulation therapy and a planned stenting procedure, intraoperative findings revealed only mild stenosis, leading to cancellation of the stent placement. The patient ultimately underwent PFO closure with an Amplatzer Talisman device. This case underscores the diagnostic challenges in managing paradoxical embolism and the need for individualized treatment, particularly concerning anticoagulation duration, the decision for PFO closure, and post-procedural antithrombotic therapy. Further research is required to establish optimal management strategies for cryptogenic embolic events.
