AB Superior  mesenteric  artery  syndrome  (SMAS),  also  known  as  Wilkie  syndrome,  arteriomesenteric  duodenal  compression,  chronic  duodenal  ileus,  or  cast  syndrome,  was  first  described  by  von  Rokitansky  in  1842,  and  is  an  unusual  form  of  gastrointestinal  obstruction  resulting  from  compression  of  the  duodenum  between  the  abdominal  aorta  posteriorly  and  the  superior  mesenteric  artery  anteriorly  (Fig.  406-1).1  In  1878,  Willet  documented  the  development  of  SMAS  in  association  with  orthopedic  casting;  however,  it  was  not  until  1927  that  Wilkie  formally  characterized  SMAS  in  a  series  of  75  patients.2,3  To  date,  the  diagnosis,  and  to  some  extent  the  existence,  of  SMAS  remains  controversial  as  symptoms  do  not  always  correlate  with  radiologic  findings  and  may  not  improve  with  surgical  correction)
