Purpose: An extensive knowledge of the arterial anatomy of the upper extremity and its variations is indispensable to the hand surgeon. We report a patient with anomalous radial artery, superficial course of two radial arteries, encountered during the excision of volar wrist ganglion. Methods: The patient was a 53-year-old man who had a painful mass on the left volar wrist for 1 year. Under general anesthesia, a curved incision was made around the mass. With the skin flaps retracted, the dome of the cyst was identified. Particular care was taken to identify and protect the radial artery, which was intimately attached to the wall of the ganglion. Two radial arteries completely encircled the ganglion. The pedicle was traced to the volar joint capsule, radiocarpal ligament. The joint was open and the capsular attachments were excised. Results: The patient made an uneventful recovery. There were two arterial pulsations at the volar side of the wrist joint. Compressing this site revealed that the major arterial contributor to blood supply in the hand was the ulnar artery. At angioCT, an anomaly of the radial artery was found with a duplication. The pathway of this aberrant artery was superficial to the original radial artery. It changed its course subcutaneously at the level of the tendon of the brachioradialis muscle, and crossing the wrist lateral to the original radial artery and ending in the deep palmar arch. Conclusion: Authors experienced a case of bifurcating radial artery encountered during the excision of ganglion on the volar of the wrist. Because these duplicated radial arteries make strong contributions to the thumb and index finger as well as to the deep palmar arch, when they are present there may be probably less blood supply to the hand from the ulnar artery. If the radial artery is palpated superficially on the brachioradialis muscle, it is important to remember the kind of anomaly.

The radial forearm free flap (RFFF) has become popular for head and neck reconstructions. Owing to a constant anatomy the RFFF is relatively easy to dissect. Nevertheless, anatomical variations of the radial artery have been reported. Some variations could affect the survival of the flap. This paper reports an unusual anomaly of the radial artery where the radial artery was not located between the brachioradialis (BR) and flexor carpi radialis. The radial artery was observed above the BR and on the radial side of the BR. The survival of the elevated flap was deemed questionable because it had only few perforators. So we decided to discard the flap and to elevate another free flap for the head and neck defect. The donor area on the forearm was covered using the original skin of the first flap as a full-thickness skin graft. This case highlights a means to deal with anomalies of the radial artery encountered during the elevation of RFFF and the checking process for variations of the radial artery before RFFF.

1970년대에 요골동맥은 관상동맥우회로술의 이식편으로 제안되었으나 적출시 나타나는 경직에 의한 이식편의 폐쇄 때문에 금지되었다. 새로운 항경직성 약물의 등장과 외상을 최소화시키는 기술의 발전은 관상동맥 우회로술의 이식편으로 요골동맥을 되살리게 되었다. Harmonic Scalpel(Ultracision Inc, Smitweld, Rl)은 요골동맥을 덜 손상을 주고, 경직이 없고, 더 빨리 적출할 수 있게 한다.

Patency of the radial artery plays an important role in the survival of radial forearm fasciocutaneous free flap and artery conduit of coronary artery bypass graft procedure. Even though Allens' test has been used for evaluating the patency of radial artery, the studies on the correlations between risk factors for atherosclerosis and histopathologic findings of radial arteries are rare, until now. Therefore, the authors investigated the correlations between these two factors, and tried to estimate the feasibility of the radial artery in high-risk groups for artherosclerosis. The risk factors for atherosclerosis and lipid profiles were investigated in 38 patients by history taking, physical examinations and blood analysis. And 38 cases of segments of vessel were harvested during the elevation of the flap. The degrees of vessel medial sclerosis were estimated by R values(by Kobayashi and colleagues) that is the median value between the thickness of the intima and that of the media. The measured mean R value was $0.210{\pm}0.05$. Thirty one cases belonged to Grade I(R<0.25), 7 cases belong to Grade II(0.25

In this paper, through a digital potentiometer and exponentially weighted moving average filter, pulse and PPG waveform measurable device was fabricated in radial artery. If this device is not proper about signal size in analog part, MCU can judge easily by adjusted amplification through digital potentiometer, using exponentially weighted moving average filter is able to filter out more clear value of ADC. I presumed pulse rate as value of measuring time between point of maximum contraction from sensing signal in radial artery of wrist. Therefore, this means can measure stable pulse rate and PPG waveform, finger as well as radial artery, whether signal size of each person is different finger as well as radial artery.

A 57-year-old male suffered from tingling and paraesthesia on radial side of right hand. We carried out exploration, the process being done, a radial artery passing between the two branches of bifurcated superficial radial nerve was found by accident. Then we performed dissection of the radial artrery a little more distally. It was passing above the extensors of thumb to anstomical snuff box. We treated it with ligating the radial artery, which was done a little above the bifurcated site of superficial radial nerve after angiography of upper extremity. While we were following this procedure, we noticed that symptoms had improved a lot. To our knowlege, neuropathy, by itself of superficial radial nerve by the radial artery with anatomical variation has never been reported and therefore we report this case.

A radial artery pulse wave is well known as a good mans to diagnose human body condition in th field of Chinese medical science. Information about constitution as well as organs can be obtained by detecting the artery pulse wave. Recently, the information about the human body constitution may be utilized in accelerating the recovery process of the patient on the basis of comprehensive diagnosis. A radial artery pulse wave is considered as one of promising means in examining the human body constitution. Since the examination has been conducted by the feeling of finger, the diagnosis may occasionally have uncertainty or fatal error. In this paper, a new measuring system is suggested and developed to examine the pattern of a pulse wave correctly. The system is composed of four pressure vessels, pressure sensors and air supplying pumps. One of them is utilized for appropriately pressing the radial artery, three of them for detecting pressure change in several mmHg level. The detected data is shown and discussed.

The radial artery is generally the preferred access route in coronary angiography and coronary intervention. However, small size, spasm, and anatomical variations concerning the radial artery are major limitations of transradial coronary intervention (TRI). We describe a successful case involving a patient with coronary artery disease who underwent TRI via a well-developed radial recurrent artery branch from the radioulnar alpha loop using a sheathless guiding catheter.

Simple ganglions are most common benign tumor of the hand and wrist. However, cystic adventitial disease is an uncommon vascular anomaly first described in 1947 in the external iliac artery. It usually involves the popliteal artery, although other arteries and veins may also be involved. Radial artery adventitial cysts are found directly within the adventitia, whereas the more common wrist ganglions may extrinsically compress or adhere to the artery walls. The diagnosis is rarely made before surgery because of their similar appearance and location. The authors report a rare case of a 46-year old woman with mucoid adventitial cyst of the radial artery in the wrist.

Objective : The transradial catheterization (TRC) is becoming widespread, primarily for neurointerventions. Therefore, the evaluation of radial artery puncture in clinical practice and a better understanding of the anatomy are important to improve the safety of neuroendovascular surgery. Methods : Ten formalin-fixed adult Korean cadavers were dissected to expose radial artery (RA), brachial artery (BrA) and subclvian artery (ScA), bilaterally. Vessel lengths and diameters were meaured using a caliper and distance between the specific point of vessels and the anatomical landmarks including the radial styloid process, the medial epicondyle of the humerus, the sternoclavicular joint, and the vertebral artery orifice were also measured. Results : The average length between the radial (RAPS) and the BrA puncture sites (BrAPS) and between the vertebral artery orifice (VAO) and the BrA bifurcation (BrAB) did not differ between sides (p>0.05). The average length between the radial styloid process (RSP) and the RAPS was $13.41{\pm}2.19mm$, and the RSP was $26.85{\pm}2.47mm$ from the median nerve (MN). The mean length between the medial epicondyle (ME) and the BrAPS as $44.23{\pm}5.47mm$, whereas the distance between the ME and the MN was $42.23{\pm}4.77mm$. The average VAO-ScA angle was $70.94{\pm}6.12^{\circ}$, and the length between the ScA junction (SCJ) and the VAO was $60.30{\pm}8.48mm$. Conclusion : This study provides basic anatomical information about the radial artery and the brachial route and can help improving new techniques, selection of size and shape of catheters for TRC. This can help neurointerventionists who adopt a transradial neuroendovascular approach and offers comprehensive and safe care to their patients.
