Acute Endovascular Therapy for Iatrogenic Vertebral Artery Injury: A Case Report

Case reports on mispuncture of the vertebral artery (VA) related to internal jugular vein (IJV) puncture are rare, and most cases were reported as vertebral arteriovenous fistulae or pseudoaneurysms detected in the chronic phase after mispuncture.1–3) The number of case reports in which acute-phase mispuncture required treatment is limited and there are no treatment guidelines.4,5) We report a patient in whom an 8-Fr. sheath was misinserted into the right VA through the right IJV immediately before open heart surgery and endovascular therapy was performed immediately after mispuncture, leading to a favorable outcome.
