Detection of arteriography-negative anterior spinal artery branching via intercostobronchial trunk confirmed by CT during intercostobronchial trunk arteriography: A case report

Abstract

Spinal cord ischemia is an important complication of bronchial artery embolization for hemoptysis. It has been reported even though a spinal artery was not visualized on arteriography. We could show a 67-year-old man with repeated hemoptysis. His hemoptysis gradually worsened and diagnosed with severe hemoptysis, and transarterial embolization was planned to stop the hemoptysis. An anterior spinal artery arising from intercostobronchial trunk confirmed by computed tomography during arteriography even though it was not visualized on arteriography. Great care should be taken with transarterial embolization via intercostobronchial trunk, potentially branching the spinal artery, even though it was not visualized on arteriography alone.
