Abstract:

Background: Venous network of hand is superficially placed and is easy to trace for clinical purposes. Ce-phalic vein on lateral aspect and basilic vein on medial aspect of the hand are clinically important for inva-sive and surgical procedures. Thus the study of cephalic and basilic veins at dorsal venous arch of hand was dissected to observe for length of dorsal venous arch and the diameter and thickness of cephalic and basilic veins. Methods: This is a cross-sectional observational study conducted in 50 hands of cadavers (36 hands of male cadavers, 14 hands of female cadavers) in Depa

Abstract:

Background: The dorsal venous arch (DVA) is a superficial venous network of the hand. It is formed by the union of four dorsal metacarpal veins in the middle of the dorsum of the hand. Medially and laterally the dorsal venous arch continues as basilic and cephalic veins respectively. Commonly, these veins are chosen for intravenous procedures, the most prominent being the dorsal metacarpal veins. The present study aims to study the different types of formation of dorsal venous arch in both the sexes. Methods: 100 hands of voluntary participants were studied (50 male hands, 50 female hands) in

Background The hands are an important aesthetic feature that can reveal aging through surface pigmentary changes, loss of skin thickness and ectatic dorsal hand veins. Techniques addressing these changes already exists but are not routinely combined for optimum results.

Abstract:

One of the most convenient biometrics approaches for identifying a person is dorsal hand veins recognition. In recent years, the dorsal hand veins have acquired increasing attention because of its characteristics such as universal, unique, permanent, contactless, and difficulty of forging, also, the veins remain unchanged when a human being grows. The captured dorsal hand veins image suffers from the many differences in lighting conditions, brightness, existing hair, and amount of noise. To solve these problems, this paper aims to extract and recognize dorsal hand veins based on the largest co

Abstract:

Dorsal hand vein recognition, with unique stable and reliable advantages, has attracted considerable attention from numerous researchers. In this case, the dorsal hand vein images captured by the means of transmission infrared imaging are clearer than those collected by other infrared methods, enabling it to be more suitable for the biometric applications. However, less attention is paid to individual age estimation based on dorsal hand veins. To this end, this paper proposes an efficient dorsal hand vein age estimation model using a deep neural network with attention mechanisms. Specifically,

Abstract:

For many years, medical professionals have relied on limited technology to locate the veins within their patients, however, this method has proven less effective for pediatric and elderly patients [1]. We propose a low-cost handheld scanner that determines the dorsal vein locations of a hand and uses the venous patterns to identify the patient. A hand dorsal vein pattern makes an excellent patient identification method in clinics or hospitals with more complex situations, as wearing personal protective equipment such as a mask can make it difficult to identify patients.

Abstract:

Security is an essential part of our lives today as people have many accounts and each account generally has a high amount of transactions. Biometrics are in the trend as it reduces risk and is quite difficult to replicate. Currently most popular biometrics such as fingerprint, retina can be forged. Dorsal Vein pattern is gaining attention these days due to its contactless nature and difficult to forge. These vein patterns can give rise to another reliable biometric which is better than the biometrics being currently used. In this paper, we have discussed the technique to extract the important

Abstract:

Background: Ischemia of the hand is a debilitating condition. In many cases, the cause of ischemia is diffuse atherosclerosis with no distal vessels available for bypass. In these situations, options are limited to restore perfusion, and there is a potential role for arterialization of the venous system to relieve ischemic pain and avoid amputation. Methods: This is a retrospective review of all patients at our institution who underwent arterialization of the venous system between 2010 and 2014 by 4 surgeons for acute or chronic ischemia of the upper extremity not amenable to bypass procedures

Abstract:

We report our experience of using the medial sural artery perforator flap in the reconstruction of soft tissue defects in the hand in seven cases with 1 to 2 year follow-up. The flap is harvested from the posteromedial aspect of the leg, just below the knee and superficial to the medial head of the gastrocnemius muscle. It is based on the perforator arteries and veins supplied by the medial sural artery. The flaps ranged in size from 14 × 10 cm to 8 × 6 cm. The donor area was closed directly or by a skin graft. All but one flap survived. The cosmetic results were satisfactory and without appar

Abstract:

Peripheral intravenous and intra-arterial catheters often block with movement of the limb in which they are inserted. Although the cause of this blockage is commonly attributed to a valve or other structure within the vein, evidence for this is lacking. We used ultrasound to assess the cause of blockage on movement, and degree of tip movement, of 62 venous and 21 radial arterial catheters. In both venous and arterial catheters, blockage was predominantly caused by impingement of the catheter on the vessel wall, with catheter kinking and spasm of the vessel also seen.

In this study, near-infrared (NIR) technology was utilized to develop a low-cost real-time near infrared (NIR) guiding device for cannulation. A portable device that can be used by medical practitioners and also by students for their skills development training in performing cannulation. Methods. First, is the development of a reflectance type optical vein finder using three (3) light emitting diode (LED) lights with 960 nm wavelength, complementary metal-oxide-semiconductor-infrared (CMOS-IR) sensor camera with 1920 × 1080 UXGA (1080P), IR filter set for the given wavelength, and an open-sour

Abstract:

1. l-Arginine is the physiological precursor for the formation of endothelium-derived nitric oxide. The synthesis of nitric oxide is stereospecific: d-arginine is not a substrate for nitric oxide synthase. It is possible that the provision of excess l-arginine substrate might increase the vascular synthesis of nitric oxide. We have examined this possibility by studying the effects of local infusion of l-and d-arginine in the forearm resistance bed and the superficial dorsal hand veins of healthy subjects. 2. Drugs were either infused locally into a vein on the back of the hand and then the vei
