Activation of the glymphatic system during sleep – is the cerebral venous outflow a missing piece of the puzzle?
2019
Until recently, mechanisms responsible for an activation of the glymphatic system of the brain, the system which is responsible for cleansing of this organ of waste products, were unclear. A recently published paper has finally shed some light on this problem. It has been demonstrated that there is a temporary decrease of the arterial cerebral blood flow during the deep phase of sleep, which is followed by an influx of the cerebrospinal fluid into the cranial cavity, and that this phenomenon is probably responsible for the activation of the glymphatic system. Although, of as yet, this issue has not been studied, it is likely that such a mechanism is not effective in the settings of disturbe…
Diagnostic accuracy of Doppler sonography and magnetic resonance venography for the assessmentv of impaired outflow from the internal jugular vein in…
2015
Objectives: This prospective study was aimed at evaluation of diagnostic value of Doppler sonography and magnetic resonance (MR) venography in the internal jugular vein territory. Material and methods: There were assessed 126 patients (252 internal jugular veins). The patients were initially diagnosed using Doppler sonography and MR venography, and then catheter venography of the veins was performed. For the purpose of this study catheter venography was regarded the reference test. We interpreted sonographic findings in the context of criteria proposed by Zamboni and criteria by International Society for Neurovascular Disease (ISNVD). We applied MR protocols aimed at flow assessment in the …
Multiple sclerosis, an unlikely cause of chronic cerebrospinal venous insufficiency: retrospective analysis of catheter venography.
2013
Objectives It is unknown if a relationship exists between multiple sclerosis and chronic cerebrospinal venous insufficiency and if this venous pathology is a causal factor for multiple sclerosis or is a product of a neurological disease. Even so, one should expect that if multiple sclerosis were the cause for venous lesions, then patients with an extended history of the disease would present with a more severe venous pathology. Design Retrospective analysis of catheter venography of the azygous and internal jugularveins, and duration of clinical history of the disease in multiple sclerosis patients. Setting Mono-profile specialist hospital. Participants 353 multiple sclerosis patients, with…
Minimally invasive techniques in the treatment of saphenous varicose veins.
2008
Lower extremity venous insufficiency is common and increases with age. In addition to classical symptoms, it may result in skin changes and venous ulcers. Chronic venous insufficiency has a great impact on patients' health-related quality of life and is associated with considerable health care costs. Surgical ligation Of the junction with or without stripping has been the standard of care in the treatment of insufficient great and small saphenous veins. However, the recurrence rates are relatively high and surgery may be associated with serious adverse events and considerable down time; it is also cosmetically Suboptimal. To improve efficacy, patients' health-related quality of life and tre…
The European multicenter cohort study on cyanoacrylate embolization of refluxing great saphenous veins
2014
ObjectiveCyanoacrylate (CA) embolization of refluxing great saphenous veins (GSVs) has been previously described. The outcomes from a multicenter study are still lacking.MethodsA prospective multicenter study was conducted in seven centers in four European countries to abolish GSV reflux by endovenous CA embolization. Neither tumescent anesthesia nor postinterventional compression stockings were used. Varicose tributaries remained untreated until at least 3 months after the index treatment. Clinical examination, quality of life assessment, and duplex ultrasound evaluation were performed at 2 days and after 1, 3, 6, and 12 months.ResultsIn 70 patients, of whom 68 (97.1%) were available for 1…
Wielokierunkowe i całościowe podejście do leczenia żylnych owrzodzeń goleni
2011
Niniejszy artykuł omawia aspekty leczenia owrzodzeń żylnych goleni. Ze względu na niezwykle złożoną patologię ran przewlekłych, do których jest zaliczane żylne owrzodzenie goleni, tylko wielokierunkowe i całościowe podejście do leczenia może dać pożądany efekt kliniczny. Skuteczny system leczenia owrzodzeń powinien obejmować: opiekę pielęgniarską w miejscu zamieszkania chorego, specjalistyczne leczenie w centrum leczenia ran oraz rozwiązywanie psychospołecznych problemów osoby chorej w klubie pacjentów. Leczenie owrzodzeń żylnych powinno być poprzedzone diagnostyką owrzodzenia, mającą na celu wykluczenie innych przyczyn owrzodzenia niż żylne oraz wykrycie patologii, którą można skorygować c…
The comparison of quality of life assessment, and severity of clinical symptoms in patients with chronic venous insufficiency. Can one universal ques…
2003
Wstęp. Celem pracy była ocena kwestionariusza jakości życia chorych z przewlekłą niewydolnością żylną (CVI), którego podstawą były opinie i preferencje chorych, jak również zbadanie czy sposób oceny jakości życia tych chorych powinien być uniwersalny, czy też powinien zależeć od stopnia zaawansowania choroby. Materiał i metody. Materiał i metody. Materiał i metody. Jakość życia oceniono u 80 chorych ze stopniem klinicznym C-2, -3, -4 i -6 według klasyfikacji CEAP za pomocą kwestionariusza uwzględniającego: dolegliwości fizyczne, ograniczenie aktywności życiowej i problemy psychologiczne związane z chorobą. Chorych proszono, aby oceniali nasilenie każdego z problemów oraz i jego subiektywne …
Retinal abnormalities in multiple sclerosis patients with associated chronic cerebrospinal venous insufficiency
2012
Optical coherence tomography (OCT) is a non-invasive method for the assessment of optic nerve fibers and retinal ganglion cells. This study was aimed at the assessment of retinal abnormalities in multiple sclerosis patients in the context of chronic cerebrospinal venous insufficiency using OCT of the retina and the optic nerve. We examined 239 multiple sclerosis (MS) patients, including 220 patients with associated chronic cerebrospinal venous insufficiency and 19 MS patients without venous pathology. The following OCT parameters were assessed: average ganglion cell complex thickness, global loss volume, focal loss volume and average retinal nerve fibre layer thickness. Abnormalities in the…
