However, atypical imaging features and diagnostic pitfalls can delay lifesaving therapy. An intimal flap is the characteristic feature of AAD. If there is flow within both lumina, typical imaging features are probably present. If the false lumen is thrombosed or there is no intimal tear to permit flow through the… CONTINUE READING
