Diagnostic and therapeutic procedures are presented in a 29-year-old f
emale patient who suffered from severe dysphagia and rapid loss in wei
ght. In the conventional X-ray examination and barium swallow an aberr
ant right subclavian artery was suspected. MR imaging (MRI) and MR ang
iography (MRA) were done to plan the surgical correction. Postoperativ
e MRA documented exactly the complex topography after surgical correct
ion and the flow pattern in the implanted Gore-Tex stretch graft prost
hesis. Non-invasive MR angiography renders possible the concrete plann
ing of complex corrections of thoracic vessels replacing invasive cath
eter angiography.
