Applied Anatomy Of The Internal Arterial Perforation Of The Palm

Objective：This study analyzes the relationship between the number of the perforator vessels per unitarea and the skin of the finger, and sees relationship between the diameter of the perforator vesselsand the and the skin of the finger by the gross anatomy, giant micro-dissected and specimens ofmultislice spiral CT three-dimensional reconstruction techniques meticulously. To provide theanatomical basis for the individual flap design and operation of the development on clinical handsurgery at the hands.Methods:1Dissection and observation the origin, course and distribution, etc. The artery perforatingbranches of the palm side of finger on the Hand adult specimens perfused used the red latex (n=12)and ink (n=1). With a vernier caliper measurement data.2Observation the origin, course and coincide of the artery perforating branches of the palmside of fingers on the Hand adult specimens perfused used the red latex (n=12) and ink (n=1).With a vernier caliper measurement data.3Fresh adult cadavers(n=12), Perfusion latex-carboxymethyl cellulose mixed filler aftercontinuous irrigation by40℃isotonic KCl from brachial artery, and then scanning theproximal after ligation brachial artery.4scan the fixed specimens underwent multislice spiral CT (32rows), Thickness1mm,Layer distance0.5mm. Scan data into three-dimensional reconstruction workstation withMimics15.0,3-doctor, and then observe the vascular distribution of hand.Result:1Refers to the blood supply of the dorsal finger: Radial artery, ulnar artery in the radial,ulnar styloid emit different levels and branches were formed in the palm shades of rich andcomplex vascular network, namely the superficial palmar arch and deep palmar arch, which is themain source of blood supply to the fingers. Superficial palmar arch issued pinky volar ulnar arteryand3palmar artery, former traveling on the little finger ulnar; The latter has a palm deep palmararch arteries join issued a total separation of palmar and radial artery and ulnar palmar artery.Thumb and index finger main artery radial arterial blood supply to the thumb and forefinger. respectively, in the form of a dry start to see from the first metacarpal artery or separately startingfrom1,2metacarpal gap, forming a total palmar artery.2Volar skin is thick, tight, little mobility, the number of branches per unit area than the dorsalmulti-wear; Results dorsal skin and fascia mobility loose large number of wear per unit area lessbranched than the back side; Thumb, index finger, little finger than volar wear dorsal count, thedifference is obvious.3We statisticed the outer diameter of the dorsal radial collateral artery on the thumb, themain perforator2-5section refers to the past, far point and the section near the midpoint of thedorsal perforating branches, found near the midpoint of the dorsal section perforator beginningpart of the position is relatively constant, the initial outer diameter of about0.6mm. Section nearthe far point and the section near the midpoint of the outer diameter greater than0.30mm.4Each dorsal palmar artery perforating artery from the start to branches: The main artery of thethumb dorsal radial collateral perforating branches,2-5section refers to the past, far point and thesection near the midpoint of the distance from the dorsal artery perforator branches were measured,The results showed that each finger and the proximal section near the midpoint of the finger arterydorsal cutaneous branch of the artery to branch a distance greater than0.5cm.Conclusion:1The beginning part the dorsal perforator position is relatively constant at Proximal anddistal points midpoint, and the initial outer diameter and the distance from starting site to thebranch point also reach the requirements of perforator flap.2Thumb back proximal ulnar, dorsal proximal radial and ulnar of the2、3、4、5fingers, andpart of the hand between the thumb and the index finger and Metacarpophalangeal joint inter-regional can be used as an excellent finger perforator flap donor site.
