A successful endovascular repositioning of migrated transjugular intrahepatic portosystemic shunt (TIPS) stent.

The transjugular intrahepatic portosystemic shunt (TIPS) procedure is performed to create an intrahepatic tract between the hepatic and portal veins which helps to shunt blood away from the hepatic sinusoids. This shunt decreases the portal venous pressure and secondary morbidities, including variceal bleeding and recurrent ascites. However, stent migration is a known complication of TIPS stent placement which may occur both during the procedure or postprocedural.

Endovascular management of traumatic pseudoaneurysms.

Background: Pseudoaneurysms (PAs) caused by traumatic injury to the arterial vasculature have a high risk of rupture, leading to life-threatening hemorrhage and mortality, requiring urgent treatment. The purpose of this study was to determine the technical and clinical outcomes of endovascular treatment of visceral and extremity traumatic pseudoaneurysms.

Methods: Clinical data were retrospectively collected from all patients presenting for endovascular treatment of PAs between September 2012 and September 2018 at a single academic level one trauma center.

The off-label use of the Amplatzer muscular VSD occluder for large patent ductus arteriosus: a case report and review.

A percutaneous approach to the closure of patent ductus arteriosus (PDA) is the preferred procedure in the majority of cases. However, there is little experience with percutaneous closure of unusually large PDA. We report the case of a 28-year-old female with moderate left ventricular dilation and pulmonary hypertension resulting from a large 16 mm PDA.

Water-soluble complexes of star-shaped poly(acrylic acid) with quaternized poly(4-vinylpyridine).

The interaction of star-shaped poly(acrylic acid) having various numbers of arms (5, 8, and 21) and a strong cationic polyelectrolyte, viz., poly( N-ethyl-4-vinylpyridinium bromide), was examined at pH 7 by means of turbidimetry and dynamic light scattering. Mixing aqueous solutions of the oppositely charged polymeric components was found to result in phase separation only if their base-molar ratio Z = [N+]/[COO (-) + COOH] exceeds a certain critical value ZM ( ZM < 1); this threshold value is determined by the number of arms of the star-shaped polyelectrolyte and the ionic strength of the surrounding solution.

Polyisobutylene-block-poly(methacrylic acid) diblock copolymers: self-assembly in aqueous media.

Ionic amphiphilic diblock copolymer polyisobutylene-block-poly(methacrylic acid) (PIBx-b-PMAAy), with various lengths of nonpolar (x=25-75) and polyelectrolyte (y=170-2600) blocks, spontaneously dissolve in aqueous media at pH>4, generating macromolecular assemblies, the aggregation number of which depends on external stimuli (pH and ionic strength). Spherical micellar morphology with a compact core formed by the PIB blocks and a swollen corona built up from the PMAA blocks was deduced by cryogenic transmission electron microscopy. The micelles were further characterized by means of dynamic and static light scattering as well as small-angle neutron scattering.

[Toxicity assessment of the vegetable emulsifier- the aqueous extract from the common soapwort roots].

Within the limits of experimental observation the assessment of acute and subacute safety of an aqueous extract from Acanthophyllum roots with a solids content of 7%, used as an emulsifier has been manufactured by production of emulsion products. Acute toxicity (LD50) AEAR, probed on mice-male; has allowed to refer to an emulsifier to a class of nontoxic substance. The assessmentof subacute toxicity of an extract (injection in a food allowance within 30 days in a recommended dose--5 ml on 100 g of a standard food allowance) was spent on laboratory rats.

[Hypolipidemic activity of a water extract from roots carline thistle].

In the researches which have been lead on white not purebred rats--mans on model nutritional hyperlipoproteinemia it fixed hypolipidemic activity of a water extract from roots carline thistle with the content of dry solvends of 7% which.

[The search of antioxidants in plant root's extracts of the carline thistle].

The carrying out tests of water-extracts of carline thistle (plant pink, Caryophyllaceae) in Kazakhstan (extract 1) and gathered in the Primorye region (extract 2). The method of spectral and thin layer chromatography silicagel plates contain phenolys components. It is found out that both extracts contain the same bonds with the max, uptake of long waves lambda = 282 hm and lambda = 260 hm.

[Treatment of acute ulcerous gastroduodenal hemorrhage].

Basic principles of infusion-transfusional therapy, methods of endoscopic hemostasis as well as indications for surgical treatment of acute hemorrhagic ulcers of the stomach and the duodenum are presented. If is stated that valid use of endoscopic methods of hemostasis provides possibility for temporal hemostasis in 70% of patients. It endoscopic hemostasis is ineffective in hemorrhage from ulcer or in recurrent hemorrhage it is recommended to perform urgent surgical interventions.

[Lipid peroxidation in patients with hypertension and renal hypertension against a background of diabetes mellitus].

Time course of changes was studied in parameters characterizing lipid peroxidation (LPO) and the total lipids counts in red cell membranes (RCM) and blood plasma (BP) of patients with hypertensive disease (HD) and arterial hypertension in chronic pyelonephritis against the background of diabetes mellitus (DM). The study groups were DM patients (group I), those with coexistent HDDM (group II), and those with arterial hypertension caused by chronic pyelonephritis in the presence of DM (group III). All three groups of patients demonstrated intensification of the cellular membrane- and blood plasma LPO as well as increase in the total lipids counts.

[Eosinophilic reactions in bronchial asthma patients and the possibilities to neutralize them under sanatorium treatment].

Patients with eosinophilic variant of bronchial asthma demonstrate high levels of fibrinolytic activity in their bronchial secretion along with low content in same of Ig A, as evidenced by findings obtained in the course of sanatorium treatment. There is usually no correlation between the above changes and routine methods of health resort treatment. The judicious employment in a complex of therapeutic measures of aerosols of hydrocarbonate of sodium and heparin promotes neutralization of cationic proteins and large major protein of eosinophiles in the bronchial lumen whereby there occurs normalization of Ig A levels in the sputum along with lowering of its fibrinolytic activity.

[A comparative evaluation of the efficacy of immunocorrection in children with bronchial asthma living in ecologically contrasted regions].

Overall 50 children suffering from infectious-allergic bronchial asthma who live in ecologically contrasting regions were examined. Those children residing in unfavourable, in terms of ecological conditions, regions demonstrated diminution of the peripheral blood T-lymphocytes together with a decrease in their functional activity as well as in the activity of interleukin 2. It is in this group of children that immunomodulating effect of thymalin is less apparent.
