AB The  word  segment  is  derived  from  the  Latin  noun  segmentum  (“a  piece  cut  off”)  meaning  part  of  a  larger  structure.  Each  segment  has  a  pyramidal  structure  with  its  apex  at  the  hilum  and  its  base  on  the  surface  of  the  lung.  It  is  supplied  solely,  with  few  collateral  connections  between  segments,  by  the  following  structures:  (1)  a  segmental  bronchus  as  tertiary  branch  of  the  bronchial  tree;  (2)  a  segmental  branch  of  the  pulmonary  artery  (as  well  as  the  bronchial  artery);  and  (3)  a  segmental  (with  or  without  an  intersegmental)  branch  of  the  pulmonary  vein  together  with  lymphatics.  Anatomic  sublobar  segmental  resection,  or  segmentectomy,  describes  a  technique  of  excision  of  lung  tissue  based  on  the  bronchovascular  anatomy.
