Outcomes of Coil Embolization for Pulmonary Arteriovenous Fistula as Evaluated Using a Novel Soft Ultrasound Probe Pasted to the Neck

An 81-year-old woman presented to our emergency room by ambulance with gait disturbance and pain in her left neck. Magnetic resonance imaging (MRI) showed acute left-sided dorsolateral medullary infarction and an occluded left vertebral artery. The temporal bone echo window was insufficient, but our...

Sumario:An 81-year-old woman presented to our emergency room by ambulance with gait disturbance and pain in her left neck. Magnetic resonance imaging (MRI) showed acute left-sided dorsolateral medullary infarction and an occluded left vertebral artery. The temporal bone echo window was insufficient, but our pastable soft ultrasound probe attached to the cervix (PSUP) detected many microembolic signals caused by the contrast agent (cMES) in the common carotid artery. Chest CT revealed right pulmonary arteriovenous fistula (PAVF) and she underwent coil embolization for PAVF considering the possibility of paradoxical embolism via PAVF. After embolization, the cMES disappeared on PSUP. Therefore, PSUP was useful for diagnosing and confirming the interventional procedural success for performing PAVF.
