spider veins

Markus Stücker, Martin Dörler
Sclerotherapy is an important part of the treatment of varicose veins. It may also be performed in patients with contraindications for operative procedures. By adjusting the mode of application (liquid or foam) and the concentration it can be used for the treatment of all vein types. In comparison to other treatment options it is especially well suited for the treatment of spider veins and reticular veins, pudendal varicosity and so called "feeding" varicose veins in the proximity of venous leg ulcers. A current European guideline, which was approved by 23 European phlebologic societies, supports the good international standardization of this treatment technique...

A 61-year-old man presented with unstable angina 16 years after undergoing coronary artery bypass grafting with a left internal mammary artery graft to the left anterior descending coronary artery and a sequential saphenous vein graft (SVG) to the right coronary artery and an obtuse marginal branch. Transthoracic echocardiography (TTE) with a Philips iE33 machine and an S5 transducer revealed a 5.3 cm × 4.6 cm mass with a central echolucent area, surrounded by a peripheral zone of increased echodensity adjacent to, and partially compressing, the right atrium...

Predation risk is a strong selective force shaping prey morphology, physiology, life history and/or behavior. As a prime stressor, predation risk may even induce trans-generational alterations, called maternal effects. Accordingly, maternal predation risk during offspring production may influence offspring life history and anti-predator behavior. Here, we assessed whether different levels of predation risk, posed by the predatory mite Phytoseiulus persimilis, induce graded maternal effects in its prey, the herbivorous two-spotted spider mite Tetranychus urticae...

Chronic venous disease is a common condition with clinical signs and symptoms ranging from spider veins, to varicose veins, to active venous ulceration. Both superficial and deep venous dysfunction may be implicated in the development of this disease. Socio-economic factors are shaping our population, with increasing age and body mass index resulting in significant pressure on healthcare systems worldwide. These risk factors also lead to an increased risk of developing superficial and/or deep venous insufficiency, increasing disease prevalence and morbidity...

Oligonychus perseae (Acari: Tetranychidae) is an important foliar spider mite pest of 'Hass' avocados in several commercial production areas of the world. In California (USA), O. perseae densities in orchards can exceed more than 100 mites per leaf and this makes enumerative counting prohibitive for field sampling. In this study, partial enumerative mite counts along half a vein on an avocado leaf, an industry recommended practice known as the "half-vein method", was evaluated for accuracy using four data sets with a combined total of more than 485,913 motile O...

BACKGROUND: Spider veins on the lower limbs are very common and have been reported to be present in 41% of women over 50. Sclerotherapy as a traditional treatment for spider veins has a low cost, though it may have adverse sequelae. Lasers have shown fewer but still substantial complications as well. Its lower efficacy relative to sclerotherapy has limited laser application for the treatment of spider veins. OBJECTIVES: To present a new alternative in management of spider veins which involves a low voltage current delivered via an insulated micro needle with beveled tip...

BACKGROUND: Varicose veins are extremely common disease which is due to elevated superficial venous pressures. We aimed to know that if joint hypermobility causes the venous insufficiency following the prolonged standing. MATERIALS AND METHODS: This prospective cohort study conducted on the soldiers of training periods in a military base of Iran Army in Isfahan in 2013. The active-duty soldiers were first examined by a physician and their Beighton scores (BSs) were obtained...

Minocycline is among the most common drugs to cause drug-induced pigmentation. Dermal deposition of drug metabolites typically occurs in areas of vascular leakage, such as surrounding lower extremity spider veins, within erythema associated with solar elastosis, and in areas of bruising. The skin affected by minocycline pigmentation typically takes on a slate-gray coloring in affected areas. The current patient developed minocycline pigmentation after carbon dioxide laser resurfacing of her upper lip to treat rhytides in the laser-treated area...

Alkaloids are the most extensively featured compounds of natural anti-tumor herbs, which have attracted much attention in pharmaceutical research. In our previous studies, a mixture of major three alkaloid components (5, 6-dihydrobicolorine, 7-deoxy-trans-dihydronarciclasine, littoraline) from Hymenocallis littoralis were extracted, analyzed and designated as AHL. In this paper, AHL extracts were added to human liver hepatocellular cells HepG-2, human gastric cancer cell SGC-7901, human breast adenocarcinoma cell MCF-7 and human umbilical vein endothelial cell EVC-304, to screen one or more AHL-sensitive tumor cell...

Over the last years, a number of therapeutic strategies have emerged to promote axonal regeneration. An attractive strategy is the implantation of biodegradable and nonimmunogenic artificial scaffolds into injured peripheral nerves. In previous studies, transplantation of decellularized veins filled with spider silk for bridging critical size nerve defects resulted in axonal regeneration and remyelination by invading endogenous Schwann cells. Detailed interaction of elongating neurons and the spider silk as guidance material is unknown...

The recognition of lower extremity venous disease as a significant cause of morbidity and lower quality of life, afflicting up to 25 % of Western populations, has led to rapid and drastic improvements in treatment options as well as an increasing awareness of the disease. Superficial venous disease, a frequent medical problem encountered in clinical practices, is now a common reason for referral to providers offering a spectrum of interventions. Venous guidelines have been set forth by the American Venous Forum and Society for Vascular Surgery covering simple spider veins to chronic venous ulcerations...

Physicists and medical doctors "speak" different languages. Endovenous laser ablation (EVLA) is a good example in which technology is essential to guide the doctor to the final result: optimal treatment. However, for the doctor, it is by far insufficient just to turn on the knobs of the laser. He should understand what is going on in the varicose vein. On the other hand, the physicist is usually not aware what problems the doctor finds on his road towards improving a new technique. We have tried to bring both languages together in the special on Ins and outs of endovenous laser ablation published in this issue of Lasers in Medical Science...

The University Hospital of Zurich has provided an email-based medical consultation service for the general public since 1999. We examined the enquiries in a 13-year period to identify those related to vascular surgery (based on 22 ICD-10 codes specific for vascular surgery). There were 40,062 questions, of which 643 (2%) were selected by ICD-10 codes. After exclusion of diagnoses not relevant to vascular surgery, 139 questions remained, i.e. an average rate of about one per month. The mean age of the users was 43 years (range 19-88)...

CONTEXT: Hepatopathies can significantly influence both veins and arteries, these changes may cause some cutaneous stigmas, such as spider angioma (SA) and some systemic vascular changes, such as those observed in hepatopulmonary syndrome (HPS). Based on this common pathophysiological root we can assume that the SA can be skin markers of HPS. OBJECTIVE: The objective of this study is to assess whether there is a relationship between the presence of SA and HPS. METHODS: Records of 40 patients with liver cirrhosis who underwent contrast echocardiography were evaluated, in which we researched the description of SA, physical examination, and other clinical and laboratory data...

The technique of foam sclerotherapy directed at the distal most vessels, draining the ulcer bed was first described in 2010, with excellent penetration into the underlying venous network possible with this technique. Thirty-five patients have now been treated with this technique as the initial treatment at Midwest Vein Laser, USA. There have been no complications with this technique and rapid healing occurred within 4-8 weeks after the initial treatment in 90% of the patients, and all ulcers were healed at 4 months...
