title: [Applied anatomy of cervico-acromial crossing skin flap].
abstract: OBJECTIVE
  To investigate the applied anatomy of the blood supply of the cervicoacromial crossing flap and its feasibility in clinical application.
  
  
  METHODS
  5 fresh adult and 10 forman fixed adult cadaver specimens were used. The arteries, veins, cutaneous arteries, subdermal vascular network, and vascular network of the superficial layer of deep fascia in the cervico-acromial area were observed and studied under the microscope. The frontier border of the cervico-acromial area is clavicle, the posterior border is the spine of scapula, the outer border is acromion and the inner border is cervical base.
  
  
  RESULTS
  (1) The perforator branches concentrate at the front edge of trapezius muscle; (2) The vessel network around the front edge of trapezius muscle is abundant. Among the anastomosis, two or three anastomosis which across the area from the base of the neck to acromion can be observed in the axial of every cervico-acromial area. Abundant vessel network can be observed in the superficial layer of deep fascia.
  
  
  CONCLUSIONS
  The blood supply of the cervico-acromial flap is abundant, which constains constant perforator point. The cervico-acromial crossing skin flap can be applied with the rich blood supply and abundant vessel network in the superficial layer of deep fascia.
