Spinal Cord Infarction after Transcatheter Embolization of Pelvic Arteriovenous Malformation

An 80-year-old woman presented with abdominal and right lower limb pain. Radiological examination revealed pelvic arteriovenous malformations (pAVMs). Although transarterial embolization was repeated, dilation of the common iliac vein worsened. Four sessions of embolization were performed for the in...

Sumario:An 80-year-old woman presented with abdominal and right lower limb pain. Radiological examination revealed pelvic arteriovenous malformations (pAVMs). Although transarterial embolization was repeated, dilation of the common iliac vein worsened. Four sessions of embolization were performed for the internal iliac vein. Paraplegia gradually occurred a day after the final procedure. Magnetic resonance imaging revealed thoracic spinal cord edema and paraspinal vasodilatation, suggesting spinal cord infarction. Additional angiography revealed a radiculomedullary vein draining into the spinal canal from the pAVM; hence, surgical interruption was performed. Incomplete venous embolization of the pAVM caused spinal cord congestion and infarction.
