title: [Anatomical study of muscular latissimus dorsi surface vascularized by the transverse branch of thoraco-dorsal artery].
abstract: BACKGROUND
  The latissimus dorsi muscle flap is a type V according to Mathes and Nahai. It is vascularized by a proximal main pedicle represented by the thoraco-dorsal pedicle and pedicle distal accessory represented by the dorsal branches of the posterior intercostal arteries. The main thoraco-dorsal pedicle has a descending branch and a transverse branch. This anatomical study clarifies the muscular territory vascularized by the transverse branch of thoraco-dorsal artery for a secondary use after harvesting a thoraco-dorsal artery perforator flap or a muscle-sparing latissimus dorsi flap.
  
  
  METHODS
  Our study focused on ten dissections latissimus dorsi muscle taken from five fresh cadavers chest, carried out within the University Department of Anatomy. The descending branch of thoraco-dorsal artery was ligated, the transverse branch was cannulated and injected with a mixture of barium sulfate/gelatin. After freezing, a static angiotomodensitometry (3D) of each flap was performed.
  
  
  RESULTS
  The average muscular surface vascularized by the transverse branch is measured at 80% (77% minimum value, maximum value 83%) of the complete latissimus dorsi muscle. Intermuscular connections between the two branches of thoraco-dorsal pedicle were shown.
  
  
  CONCLUSIONS
  The use of a ipsilateral latissimus dorsi muscle is a therapeutic option after harvesting a thoraco-dorsal artery perforator flap (TAP) or a muscle-sparing latissimus dorsi flap (MSLD-flap).
