Delayed ulnar artery pseudoaneurysm presentation after percutaneous cardiac intervention: A case report and review of the literature.

ABSTRACT

PURPOSE: Here we present a case of a 62-year-old female with a delayed ulnar artery pseudoaneurysm presentation after cardiac catheterization. CASE REPORT A 62-year-old woman with multiple medical comorbidities including end-stage renal disease (ESRD) on hemodialysis (HD) and atrial fibrillation on tablet apixaban who presented 8 weeks after cardiac catheterization through right ulnar artery access with a pulsatile mass, pain, and tingling of her right-hand fingers. Ultrasound exam confirmed presence of ulnar artery pseudoaneurysm with >2 cm active chamber. This pseudoaneurysm was repaired via forearm exploration, evacuation of hematoma, and primary repair with non-absorbable sutures. CONCLUSION: We report a case of delayed ulnar artery pseudoaneurysm presentation following cardiac catheterization through the right ulnar artery. Open surgical repair offers a definitive addressal of ulnar artery pseudoaneurysm and removes ulnar nerve compressive neuropathy with less risk of distal embolization in patients with delayed pseudoaneurysm presentation whenever ultrasound-guided thrombin injection (UGTI) is contraindicated.
