  • Radial artery aneurysm is an extremely rare disease and this is usually caused by iatrogenic trauma such as arterial cannulation. Most traumatic aneurysms in the extremities are false aneurysms and most cases have occurred at the level of the wrist. Very few true aneurysms of the radial artery have been reported, with most of them being iatrogenic. A right handed 38-year-old female had a true aneurysm of the distal radial artery in the thenar groove of the palm. The patient had a history of excessive handclapping and the injury was suggestive of repetitive occupational injury due to scissoring. She underwent surgical treatment for the aneurysm of the radial artery in the thenar groove of the palm of her hand.

  • In this study, the pulse of radial artery and oxygen saturation are detected using photoelectric plethysmograph method. Using our device designed reflection type, we can detect the reflected light by radial artery and by switching circuit, we can also separate to 625nm band signal and 940nm band signals. The separated signals are converted as a pulse data by the pulse signal processing circuit. In this study, the reflection type of oxygen saturation calculation method is applied instead of the transmission type because of the reflection type sensor is used to measure the radial artery. As a result, we can detect about 97% accuracy of the oxygen saturation compare with the conventional method. For the accurate signals, the wrist band with sensor was designed and fixed on the radial artery. As a result, this wrist band type sensor was applicable to prevent position errors from motion artifact and could increase the accuracy during the measuring.

  • Objectives: The pulse diagnosis to identify the symptoms has been considered important in Korean medicine. The position and character of disease would be confirmed by pulse diagnosis of left and right radial artery. This paper is to analyze the characteristics and differences of left and right blood vessels. Methods: In this study, left and right radial artery and dorsalis pedis artery was measured and analyzed by using condenser typed pulse analyzer. Commercially available pulse analyzer was used to measure the radial artery. The pulse wave was measured in 20 laboratory healthy men and women. The blood vessel aging degree and index of augmentation of blood vessel was obtained from the measured pulse wave graph and the characteristics and differences of the left and right blood vessel was analyzed. Results: The significant difference of pulse transit time between the right handed and non-right handed was not found. The correlation of radial artery and dorsalis pedis artery had no significant difference. By obtaining the blood vessel aging index (AGI) and augmentation index (AI) of blood vessel at the left and right radial artery, the significant difference between right handed and non-right handed was not found. Conclusions: The result of this study would help to explain the characteristic of blood vessel with respect to the left and right handed. We suggest that research of pulse wave of the left and right blood vessel using pulse analyzer should be needed in further study.

  • Background The innervated radial artery superficial palmar branch (iRASP) flap was designed to provide consistent innervation by the palmar cutaneous branch of the median nerve (PCMN) to a glabrous skin flap. The iRASP flap is used to achieve coverage of diverse volar defects of digits. However, unexpected anatomical variations can affect flap survival and outcomes. Methods Cases in which patients received iRASP flaps since April 1, 2014 were retrospectively investigated by reviewing the operation notes and intraoperative photographs. The injury type, flap dimensions, arterial and neural anatomy, secondary procedures, and complications were evaluated. Results Twenty-eight cases were reviewed, and no flap failures were observed. The observed anatomical variations were the absence of a direct skin perforator, large-diameter radial artery superficial palmar branch (RASP), and the PCMN not being a single branch. Debulking procedures were performed in 16 cases (57.1%) due to flap bulkiness. Conclusions In some cases, an excessively large RASP artery was observed, even when there was no direct skin perforator from the RASP or variation in the PCMN. These findings should facilitate application of the iRASP flap, as well as any surgical procedures that involve potential damage to the PCMN in the inter-thenar crease region. Additional clinical cases will provide further clarification regarding potential anatomical variations.

  • Purpose: Radial and ulnar arteries are two major arteries responsible for the blood supply of the hand. We experienced early recurrent thrombosis of ulnar artery after arteriorrhaphy in a patient with rupture of ulnar and radial arteries due to glass injury. Thus, we thought this would require reviews. Method: 41 - year - old female patient was presented for the laceration of right wrist due to glass injury. Operative findings revealed the rupture of radial artery, ulnar artery, ulnar nerve and most of the flexor tendons. We performed three consecutive operations because of the recurrent arterial thrombosis in ulnar artery. Arteriorrhaphy was performed in each operation and the interpositional vein graft was performed in the final operation. Result: Consequently, doppler ultrasonography was performed on twentieth postoperative day and fair flow in the ulnar artery was visualized. Pathologic examination of the artery revealed no histopathologic abnormalities. Conclusion: It is not a matter of ease to follow up the patients with rupture of radial or ulnar arteries. Obstruction of the repaired artery is also not easy to detect because it usually presents no definite symptoms. We could detect the obstruction of the artery following arteriorrhaphy with the doppler ultrasonography in less than a week postoperatively, and repeated operations were followed. We reviewed the causes and factors affecting the thrombosis and hereby report with literature review.

  • Background: The radial arteries are being used more often for coronary artery bypass grafting, We tried to the endoscopic radial artery harvest to reduce the cosmetic problems and neurologic complications of the conventional open harvesting and report the techniques and early results. Material and Method: The 86 patients underwent coronary artery bypass grafting between May 2003 and April 2005 had their nondominant radial artery endoscopically removed through a 2 cm incision at the wrist. The radial pedicle was dissected and was divided at antecubial area through a 5 mm counterincision. Result: The 23 patients complained of neuralgias on territory of superficial raidal none but no one complained of neuralgias on territory of lateral antebrachial cutaneous none. There was no functional impairment of the hand. There was no wound complication except a localized hematoma. All patients were contacted by telephone after postoperative 7.9$\pm$3.6 months. The 4 patients still complained of neuralgia. All the patients were satisfied with the aesthetics of the wounds. The multidetectional tomography was done on the 66 patients for the estimation of early patency of radial artery. There were 2 cases of stenosis and a case of occlusion. Conclusion: Endoscopic radial artery harvest had no functional impairment of the hand, lesser rate of neurologic complications and outstanding aesthetics. The results of early patency of the radial artery was similar to conventional methods. Therefore, we think that endoscopic radial artery harvest is the optimal procedure.

  • In oriental medicine, it is possible to classify each person into eight kinds of constitutions based on the eight constitutional medicine theory. We developed a piezoelectric 3-channel tactile sensor using PVDF (polyvinylidene fluoride) film for pulse detection of the radial artery. High frequency buffer (impulse buffer), amplifier, 60 Hz noise notch filter and low pass filter were integrated on three sheets of PCB board. The pulses of the radial artery at three points were checked using our system. Each constitution of the eight ones has different combinations of pulses.

  • This paper suggests a new experimental system and protocol of mechanical analysis for arterial cross-section research. So far, most methods of arterial studies have been focused on the deformation measurement in longitudinal and circumferential direction. The deformation in radial direction has been theoretically assumed by Poisson's ratio and/or the incompressibility of arterial wall. Also, the radial gradient of strains are neglected. In fact, the radial deformation and radial gradient of strains against blood pressure are important to be observed in the pathological point of view of artery. Proposed experimental system and protocol are to measure the deformation of cross-sectional artery. Also, this method enables to measure the deformation of anterior, posterior, and side site of cross-sectional area. It is meaningful to correlate the mechanically experimented data with pathological data of athroscIerotic artery.
