Abstract:
Thirty two upper limbs of 16 adult fresh cadavers were studied.Suspension ofbarium sulfate in red latex were injected prior to medial arm flap dissection.Thearm flaps were observed and measured under the magnifying spectacles(3X),and X-ray photographs were taken.The main results obtained are summarized as follows:1.In 30 specimens,there are 386 branches arising from the brachial artery——pure cutaneous branches(67,17.36?1.93%),pure muscular and myocutaneous branches(186,48.182?2.54%)and mixed branches(133,34.46?2.42%).2.The brachial profundal artery arises from the brachial artery about 2 to 3cm.below the lower margin of pectoralis major.The caliber of the artery is 2.22?0.14mm.It supplies the triceps brachii and the skin of medial and dorsal surfaceof the upper part of arm.3.The superior ulnar collateral artery arises from the brachial artery about 6cm,below the lower margin of the pectoralis major.The caliber of the artery is1.71?0.08mm.It supplies the long and medial head of Triceps Brachii and the skinof middle and lower part of arm.It is a main artery of medial arm flap.4.The inferior ulnar collateral artery arises from the brachial artery about 18cm,below the lower margin of pectoralis major.The caliber of the artery is 1.50?0.07mm.5.The myocutaneous artery of biceps brachii arises from the brachial arteryabout 8cm,below the lower margin of pectoralis major.The caliber of the artery is1.63?0.13mm.It gives off a larger cutaneous artery.6.An abundance of anastomoses is formed by these cutaneous arteries and arich network of arteries may be seen.The caliber of some of the cutaneous arteries isabove 1mm.7.The venous drainage consisted of venae comitants.The medial arm flap is generally thin,soft and non-hair-bearing,the caliberand length of the pedicles of the arteries are large enough for microsurgical vasoanas-tomosis.It is a suitable donor site for free transfer of skin flap and the optimaldimension is 8?20cm.
