[Efficacy of combination of needle extract, hesperidin and vitamin C in treatment of chronic venous diseases]. / Éffektivnost' kombinatsii ékstrakta iglitsy, gesperidina i vitamina S v lechenii khronicheskikh zabolevanii ven.

BACKGROUND: In Russia, physicians are virtually unaware of drugs based on needle extract. However, abroad, saponins and, in particular, a combined preparation containing needle extract, hesperidin and vitamin C is one of drugs of choice, if not the leading medication in treatment of venous oedemas and other venous symptoms. AIM: The authors conducted a systematic review of the Russian-and English-language literature using the following search terms: saponins, hesperidin, needle, ruscus, ruscogenin (and their Russian equivalents), each of which was entered in a combination with the word 'venous' or its Russian equivalent, respectively. RESULTS: Ruscogenin and neoruscogenin from the root of needle possess anti-inflammatory properties and induce venous wall contraction, thus making it possible to use needle extract in treatment of chronic venous insufficiency. It was experimentally determined that needle extract stimulates vein contractility, decreasing permeability of the venous wall, influencing extracellular matrix proteins, inhibiting leukocyte migration through regulation of both proteins and matrix ribonucleic acid. Analysed herein are the results of original studies of a combination of needle extract, flavonoid hesperidin methyl chalcone and ascorbic acid, also examining in detail the mechanism of action conditioned by synergism of pharmacological effects of these components. This is followed by discussing the place of saponins in the classification of phlebotropic drugs and comparing efficacy of needle root extract with that of other phlebotonics. CONCLUSION: It was experimentally determined that a combination of needle extract, hesperidin and vitamin C possesses multiple additive phlebotropic effects. According to clinical trials, it leads to relief of most symptoms and a decrease in the ankle volume (high level of evidence 1A), being not inferior by clinical efficiency and duration of action to the best-known flavonoids, whereas by the venotonizing effect, decreased permeability of the vascular wall, and inhibition of leukocytic aggression even superior thereto. Further experimental and clinical studies of efficacy of this combination for various forms of chronic venous diseases and venous thromboses are warranted.

[Endovascular treatment of a patient with post-thrombotic disease and obstruction of a cava filter]. / Éndovaskuliarnoe lechenie bol'nogo s posttromboticheskoi bolezn'iu i obstruktsiei kava-fil'tra.

Balloon angioplasty and stenting have increasingly been gaining widespread application for treatment of post-thrombotic alterations in the system of the vena cava. Endovascular ultrasonographic examination makes it possible with the utmost degree of reliability to determine both the extension and degree of the narrowing of venous segments, thus proving a possibility of choosing a venous stent of an appropriate diameter. Restoration of an adequate venous lumen leads to normalization of blood flow and elimination of venous hypertension. However, unsolved as yet remains the problem concerning proper management of post-thrombotic obstructions of the inferior vena cava at the level of a cava filter. Owing to a wide variety of configurations of cava filters to deploy, there are no common approaches to elimination of such obstruction. Presented herein is a clinical case report regarding successful endovascular treatment of a patient diagnosed with post-thrombotic disease secondary to endured thrombosis. The findings of both phlebography and endovascular ultrasonographic examination made it possible to diagnose obstruction of the left common iliac vein, external iliac vein, and inferior vena cava to the level of the cava filter previously deployed. In the segment of the inferior vena cava at the level of the cava filter also revealed was a pronounced luminal narrowing exceeding 90% of its diameter. We carried out stenting of the common and external iliac veins, inferior vena cava, and the cava filter. Swelling of the left leg subsided spontaneously within 2 weeks and the first postoperative month was accompanied by gradual disappearance of the previously existing feeling of heaviness in the lower limbs and a dramatic decrease in fatigue by the end of the working day.
