Miega artērijas audzēju ķirurģiska ārstēšana Latvijā no 2010. līdz 2015.gadam

2016

Ievads: Miega artēriju audzēji (MAA) ir reti, lēni augoši un labi apasiņoti neiroendokrīni veidojumi, kuru izcelsme ir miega artērijas bifurkācijas līmenī esošās paraganglionārās šūnas. Mērķis: Pētījuma mērķis bija izpētīt MAA pacientus Latvijā pēdējo piecu gadu laikā, veicot demogrāfisku, kā arī ārstēšanās iznākumu analīzi. Materiāli un metodes: Tika veikta retrospektīva analīze, caurskatot pacientu slimības vēstures no 2010. līdz 2015. gadam Paula Stradiņa Klīniskās Universitātes slimnīcā, kurā esošais asinsvadu ķirurģijas centrs ir vadošais Latvijā, kurā ārstē MAA. Pētījuma ietvaros pacienti tika arī uzaicināti uz duplex ultrasonogrāfiju apsekošanai. Rezultāti: Kopumā 10 pacientiem tika …

CD59 (homologous restriction factor 20), a plasma membrane protein that protects against complement C5b-9 attack, in human atherosclerotic lesions

1992

Blood cells express a cell membrane protein, termed homologous restriction factor 20 (HRF20) and identical to CD59, that can inhibit complement C5b-9 insertion into their membranes. In this report, we investigated by immunohistochemistry whether CD59 was present on cells in human atherosclerotic lesions since membranous C5b-9(m) has been found in lesions. Using a monoclonal anti-CD59 antibody, a cellular CD59 staining pattern was apparent in nearly all lesion specimens. CD59 stain co-localised with macrophage (CD14), T lymphocyte (CD7), endothelial cell (anti-factor VIII related antigen) and smooth muscle cell cytoskeletal-specific antigens (anti-alpha actin and muscle myosin). Endothelial …

Long-term performance of the bovine pericardium patch in conventional carotid endarterectomy.

2014

Objective The aim of the study was to analyze long-term results of carotid endarterectomy (CEA) using bovine pericardium patch. Patients and Methods This study is a retrospective analysis of 274 consecutive cases (173 in CEA group and 101 patients in an internal control group of eversion endarterectomy [EEA]) operated between January 2005 and May 2007. Operations were performed according to standard surgical technique. Primary endpoints of the study were 30-day mortality, ipsilateral neurologic event rate, and high-grade restenosis in the long-term follow-up. Results No statistically significance between both groups was found in terms of gender, age, risk factors, medication (statine, plate…

Laser Welding - Suitable for Vascular Anastomosis?

1994

Carotid arteries of 21 piglets were transsected and reanastomosed either by laser welding (Neodym:YAG laser) or by conventional suture anastomosis. Histological specimens of the anastomoses obtained 2 to 32 days after the operation showed less foreign body reaction and intimal hyperplasia after laser welding than after suturing. There was, however, no significant difference when comparing occurrence of thrombosis, patency rate, or growth of the anastomosis in growing animals. Neither our study nor a review of the literature of laser-assisted vascular anastomosis in microvessels and large arteries up to 5 mm diameter could establish a definite clinical application for laser welding in vascul…

SYSTEMIC ARTERIAL CHANGES AND PULSE PRESSURE: DIFFERENT IMPACT ON RENAL HAEMODYNAMICS IN HYPERTENSIVE PATIENTS.

2015

Objective: Renal resistance index (RRI) is used for kidney disease detection and prognosis, but it also appears a good indicator of systemic vascular changes in hypertensive subjects. Structural atherosclerotic damage, arterial stiffness and pulse pressure may interact each other, and the relationship between intrarenal haemodynamics and systemic vascular alterations has been widely investigated. However, the independent impact of all these parameters on renal haemodynamics and the mechanisms by which they affect renal vasculature remain to be clarified. Design and method: We enrolled 463 hypertensive patients (30–70 years) with normal renal function (group 0; n = 280) and with chronic kidn…

Influence of Severe Carotid Stenosis on Cognition, Depressive Symptoms and Quality of Life.

2017

Background: Carotid artery disease is not just a causal risk factor of ischemic stroke, but may predispose patients to depressive symptoms and low health related quality of life (HRQoL). Objectives: The objectives of the present study were to assess the association between severe carotid artery stenosis (CAS) and cognitive impairment, frequency of depressive symptoms and status of HRQoL. Methods: Cross - sectional study involved 55 patients with severe CAS and 54 patients with lower extremity peripheral artery disease (PAD). Cognitive impairment was assessed using Montreal Cognitive Assessment Scale (MoCA), depressive symptoms - PHQ-9 scale. HRQoL was measured using Medical Outcome Survey …
