Abstract:
Objective:To describe the general and histological features of the full-length superficial fascia of the circumferential upper limb.
Methods:Fresh frozen arm specimens were dissected, and then MRI imaging in vivo, enhanced CT angiography and HE histological staining were used to describe the characteristics of the full-length superficial fascia of the circumferential arm and its relationship with important blood vessels.
Results:The four typical structures of the superficial fascia of the arm were divided into subcutaneous superficial fat, membrane-like substance, deep fat and deep fascia from superficial to deep. The thickness and stratification, fusion degree and histological characteristics of the superficial fascia of these four layers were obviously different in different levels and regions of the arm. MRI confirmed that the total thickness of superficial fascia gradually decreased from shoulder to wrist. Venography showed that the cephalic vein ran below the second layer of superficial fascia and above the deep fascia. The basilic vein originated from the dorsal vein network of the hand and always lied below the second layer of membranous material until the basilic vein penetrates below the deep fascia of the upper arm.
Conclusions:The deep understanding of the circumferential full-length of superficial fascia structure of the upper limb provides an important theoretical basis for improving the surgical safety and fine operation for the Dynamic Arm Circumferential Liposuction.
