    Percutaneous Brachial Artery Catheterization

    Elliot 0. Lipchik, MDHideharu Sugimoto, MD

    We describe modifications and sugges-tions for safer percutaneous catheteriza-tion of the brachial artery based in parton the anatomy of the axillary-brachialartery and surrounding nerves of thebrachial plexus. The brachial artery ap-proach should be nearly as safe as thefemoral artery approach for percutane-ous catheterization and should not beavoided if the femoral arteries cannot beused.

    LTHOUGH the axillary artery hasbeen used for percutaneous cath-

    etenization for more than 20 years (1,

    2), it is still shunned by many angiog-raphers because of their fear of in-

    creased complications (3). We present acatheterization technique that is safe

    with a relatively low complication mate.

    Materials and Methods

    1 . Catheter sizes that we used rangedfrom 5 to 7 F and were of various con-figurations. The actual site of puncture

    is the proximal brachia! artery, well

    distal to the lateral edge of the pectoral

    muscles. A higher, more proximal

    puncture into the axilla should be

    avoided since hemostasis is difficult to

    achieve there, hematoma formation caneasily be hidden, and the artery is diffi-

    cult to fix in position. The puncture istherefore made distal to the origin of

    the subscapulan and circumflex humer-a! arteries.

    2. The patients arm is abducted and

    elevated, with the patients hand rest-ing under the turned head or on the ta-

    ble above the head.3. The physicians index and middle

    fingers (used for palpating) should beplaced lengthwise along either side of

    the artery to fixate it and to avoid mad-

    vertent compression of the artery.

    4. Contrary to other authors mecom-

    mendations (4, 5), the needle approach

    should be almost perpendicular to theplane of the artery. This ensures fixa-

    tion of the vessel and puncture at thepoint of maximum pulsation on theventral surface of the artery exactly cor-responding to the direction of the anes-

    thesia needle track. This should help

    the physician avoid touching the

    nerves of the bmachial plexus and avoid

    more proximal intmaaxillary artery

    punctures. Not more than 3 ml of lido-

    caine 1% is needed. Brachial nerveblock should be avoided, also contrary

    to prior recommendations (3-5).

    5. The patient is instructed to tell usimmediately if he perceives an electric

    shock down the arm into the handduring placement of the anesthesianeedle or arteniogmaphic needle. If the

    shock occurs, the needle must be

    slightly moved either proximal or dis-tal along the artery.

    6. An assistant (technologist, nurse,

    trainee) continually palpates the radial

    artery pulse during the needle ap-

    proach. The axillary-bmachial arterycompresses more easily than the femo-

    nal artery and often does not transmitpulsations through the needle to the

    operators hand. However, the radialartery pulse frequently disappears asthe needle approaches and compresses

    the brachial artery. When this is notedby the assistant, a short jab of the nee-

    die should cause the needle to enter

    the artery despite the lack of transmit-ted pulse.

    7. After the punctume has been con-

    rectly achieved, with blood spurtingfrom the needle, the needle is lowered

    for guide wire insertion. One-wallpuncture, using an open needle, may

    decrease potential bleeding.

    8. Removal of the catheter withfishing is identical to previously de-scnibed catheter removal technique (6);

    manual pressure on the artery puncturesite should be maintained for at least iOminutes after removal of the catheter.

    Distal pulses should be presentthroughout the anteniographic pmoce-

    dune.

    Results

    During the past 5 years, 1,700 consec-

    utive aortofemora! angiograms havebeen obtained at our institutions. Ofthese, 1 10 (6.5%) were obtained via the

    axillary artery approach becauseblocked aortas, blocked femomal arter-

    ies, on recent surgery militated againstthe femoral artery approach.

    Of the 1 10 attempts to perform the

    technique, two were unsuccessful ow-

    ing to an inability to enter the vessel orthe aorta because of extreme amtenio-

    sclerotic changes of the subclavian an-tery. These examinations were success-fully completed via the translumbamapproach.

    In 65 procedures performed by oneof the authors (E.O.L.), no major corn-

    plications were noted. A total of two

    complications (1 .8%) occurred, duringprocedures performed by other staffphysicians: one case of persistent might

    median nerve injury and one case ofacute thrombosis on the left side. The

    thrombosis was removed by surgerywith no sequelae.

    Discussion

    The axillary artery begins at the lat-

    era! border of the first rib and ends atthe inferior margin of the teres major

    muscle, where it continues as the bra-chial artery. The bmachial artery is distal

    to the origin of the subscapular artery

    and the circumflex humera! arteries.

    The axillary artery is surrounded on a!!

    sides by three bundles of the bmachialplexus (nerves of C-S through T-i).These dorsal, lateral, and media! cords

    then divide and form into their nespec-

    tive large nerves. The median nerve(the one most often injured in axillary

    catheterizations) is formed from boththe lateral and medial cords joining on

    the ventral aspect of the axillary artery(Fig. 1). It then runs on the superolat-era! side of the brachial artery. Thus,

    the first portion of the bmachial artery isrelatively clear of nerves on its ventralaspect, whereas higher, the axillamy am-

    teny is completely surrounded. Itshould also be emphasized that the am-

    temy and nerves run in a surrounding

    common fibrous sheath.

    The prevalence of brachial plexus in-jury and overall complications variesmarkedly in the literature from 0.5% to33% (3, 4, 7-9). In one nationwide sum-vey of the complications of angiogra-

    phy, Hessell et a!. (10) reported that the

    overall prevalence of complication ofthe axillamy approach is 3.29%, signifi-

    cantly higher than that of the femoma!

    approach (1.73%). Most of the differ-ences reportedly resulted from localcomplication, such as hemorrhage,

    thrombosis, and pseudoaneurysm. U

    Femoral Torsion: CT Measurement

    We report a new method using comput-ed tomography (CT) to measure femoraltorsion more accurately in patients withcerebral palsy. The method involves CTscanning through the femoral head, thefemoral neck at the region of the greatertrochanter, and the femoral condyle.
