trans-2-Aminocyclohexanol-based amphiphiles since remarkably productive associate lipids for gene shipping through lipoplexes.
Iliac artery aneurysms are relatively uncommon, however requiring early diagnosis and treatment because of high mortality once ruptured. Endovascular correction is currently a method of choice. The standard iliac components of aortic stent grafts have a linear or distally widening shape, whereas the anatomy of aneurysms of iliac arteries requires, as a rule, a larger diameter of the proximal zone of shrinkage. Optimal is considered to be the use of reversed stent grafts, i. e. those tapering distally. The authors herein share their experience in treating iliac artery aneurysms using a flared reversed endograft of the iliac branch of the Anaconda stent graft in three patients presenting with iliac artery aneurysms. Technical success was achieved in all cases. In the remote period (6-12 months postoperatively) the grafts were patent, with no leakage.
This study was undertaken to evaluate the efficacy of three-stage measurement of the transit-time flow through coronary bypass grafts with the help of flowmetry for early verification of technical errors during on-pump coronary artery bypass graft surgery.

We performed an intraoperative analysis of 214 bypass grafts with the help of three-stage flowmetry. The first stage of measuring was performed on-pump with and without the proximal loop test, the second stage of measurement was performed after weaning the patient off the heart-lung machine, and the third stage of measurement was carried out after heparin inactivation prior to chest wound closure.

Amongst the 214 transplants regarded as functioning, intraoperative flowmetry revealed insufficient blood flow in 9 (4.2%) cases. Tinengotinib clinical trial Technical surgical errors were confirmed in these shunts during revision thereof. In 6 (2.8%) of the 9 such grafts we detected non-optimal parameters of flowmetry during the first measurement (while the heart was stopped); of thestionality of coronary artery bypass grafts at all stages of the operation, thus allowing timely verification and immediate correction of any technical problems with coronary artery bypass grafts.Critical ischaemia of lower limbs is a cause of death and invalidity in the whole world. Stem cells and products of their secretion find wide application in treatment of vascular diseases, including critical ischaemia of the lower limbs. Erythropoietin promotes an increase in the angiogenic potential of stem cells. The authors examined the therapeutic potential of a biomedical cellular product (mesenchymal stem cells and products of their secretion) and mesenchymal stem cells with erythropoietin on the processes of restoration of vessels in the hind legs of Wistar male rats following induction of lower limb critical ischaemia. Mesenchymal stem cells were derived from the bone marrow of male Wistar rats. Critical ischaemia of hind legs was modulated by transaction of the femoral artery. The parameters of microcirculation in the foot were assessed with the help of laser Doppler flowmetry. In the blood serum and crural muscles by means of solid-phase enzyme immunoassay we examined the levels of cytokines, growth factors, and persistent metabolites of nitrogen oxide - nitrites. Muscles morphology and the number of blood vessels were assessed by the findings of histological examination. It was shown that the biomedical cellular product alone and in combination with erythropoietin stimulated angiogenesis. The results of Doppler flowmetry revealed restoration of the parameters of microcirculation in the lower limb by 35-75% of the baseline values. Besides, we observed a decrease of muscle necrosis, connective tissue proliferation, and an increase in the number of the vessels supplying the muscles in the experimental groups. It was also determined that the biomedical cellular product influenced the levels of cytokines in blood serum and crural muscles. Hence, the obtained findings proved the therapeutic potential of the biomedical cellular product in critical ischaemia of lower limbs.This article presents a review of the literature on studying Cilostazol, a type 3 phosphodiesterase inhibitor, also providing the Russian and foreign statistics on the prevalence of peripheral artery disease. It is underlined that the majority of patients with peripheral artery disease have atherosclerotic lesions in the coronary and cerebral vascular basins. Cilostazol deservedly occupies the first lines in the sections of pharmacotherapy for intermittent claudication in international and Russian consensus documents on peripheral artery disease. The drug has an extensive evidence base for the following pharmacological effects vasodilating, antiplatelet, endothelial protective, and vasculogenic. Clinical efficacy of Cilostazol was confirmed in 15 randomized clinical trials (3 718 patients with intermittent claudication) studying the use of Cilostazol taken twice daily at doses of 50 mg, 100 mg, and 150 mg as compared with placebo or versus pentoxifylline given in a dose of 400 mg three times daily, with a demmparative efficacy of Cilostazol and pentoxifylline in patients with intermittent claudication.The routine practice of a vascular surgeon is invariably associated with decreasing the risk of adverse cardiovascular events in patients presenting with either arterial or venous pathology. Antithrombotic therapy is one of the key approaches used to achieve this purpose. However, a wide variety of modern drugs inhibiting platelet aggregation and agents blocking the coagulation cascade, as well as their combinations makes the selection of the most appropriate treatment for a particular patient quite a difficult task. The choice should carefully be made taking into consideration the nosology, aetiology, accompanying diseases and therapy thereof, as well as the balance of the risk of ischaemic and haemorrhagic complications. Therefore, availability of modern antithrombotic drugs favourably contributing to a more personified approach to treatment is of utmost importance. Thus, for example, rivaroxaban, an anticoagulant belonging to the class of direct-acting oral factor Xa inhibitors, provides a possibility to select an optimal dosage and regimen for a particular patient with arterial or vascular pathology in practice of a cardiovascular surgeon.
