Inhibitor development is one of the most challenging complications of haemophilia management. Haemostatic control in patients with haemophilia with inhibitors can be difficult, and is especially risky in those undergoing surgical interventions. Most haemophilia patients with inhibitors suffer from chronic joint disease requiring surgical correction due to recurrent bleeding episodes. The aim of this study was to assess the use of recombinant activated factor VII (rFVIIa) as haemostatic therapy during orthopaedic surgery in haemophilia patients with inhibitors. A series of case reports was retrospectively collected to describe clinical experience of rFVIIa use in inhibitor patients undergoing a range of orthopaedic surgical procedures at a single centre. All surgeries were performed using standard methods. All patients received rFVIIa at a starting dose of 120 μg kg(-1) with the subsequent regimens depending on the type of surgery. rFVIIa provided effective haemostasis in 23 patients with haemophilia A and inhibitors (15 with high inhibitor titres) undergoing orthopaedic surgery. The majority (70%) of surgical procedures were major (joint and extra-articular surgery). The doses and intervals of rFVIIa treatment used varied depending on the severity of bleeding, and the type (major or minor) or site of surgery. In all cases, administration of rFVIIa achieved good haemostasis. In all 23 patients with haemophilia with inhibitors, rFVIIa treatment in orthopaedic interventions proved to be an efficient haemostatic agent, providing effective intra-operative and postoperative haemostasis.

Despite treatment advances, the prognosis of patients with both primary and secondary pulmonary hypertension (PH) remains unfavorable. The increased activity of the sympathetic nervous system is one of the universal mechanisms involved in the PH pathogenesis. Pulmonary artery denervation is a novel minimally invasive pathogenetic method of PH treatment. The denervation procedure is mainly implemented by using radiofrequency ablation of the pulmonary trunk, where most sympathetic nerve fibers are located. In this article we present an overview and analysis of the present state, results of various experimental and clinical studies, as well as clinical experience. The results of studies demonstrated the safety of endovascular surgery and its beneficial effect on both hemodynamic and clinical parameters.

Aim. To assess the dynamics of blood pressure (BP) and determine the predictors of the hypotensive effect after carotid artery stenting (CAS).Material and methods. The analysis included 99 patients who underwent CAS in a period of March 2014 and May 2016. Inclusion criteria: (1) the presence of 50% symptomatic or 70% asymptomatic stenosis of the carotid artery (according to NASCET criteria), (2) follow-up for at least 1 year, (3) measurement and recording of BP at four points: 24 hours before surgery, 1 hour, 24 hours and 12 months after surgery. Results. According to office measurement of BP, the average systolic/diastolic pressure was 117,11/60,75, 119,73/60,75, 134,75/70,48 mm Hg after 1 hour, one day and 12 months after the intervention, respectively. In comparison with the average numbers of BP before the intervention, 148,13/89,52 mm Hg there was a significantly significant decrease in BP levels after CAS (p<0,01). According to the results of daily monitoring of blood pressure, a statistically important decrease in blood pressure was observed after 1 year of observation (p<0,01) (136,52/76,84 compared with 145,91/87,63 before the intervention). Dissociated circle of Willis (odds ratio=10,37, 95% confidence interval, from 3,64 to 29,52; p<0,001) and the occurrence of intraoperative hypotension (odds ratio =3,62, 95% confidence interval, from 1,16 to 11,28; p<0,027) were predictors of a persistent decrease in BP after CAS. Conclusion. The obtained results indicated the need for more thorough conservative postoperative management, especially for patients with a dissociated circle of Willis. It is also necessary to achieve the target blood pressure values by individualized correction of antihypertensive therapy.

Aim. To study the effect of catheter-based sympathetic renal denervation (RDN) by radiofrequency ablation on glucose metabolism in patients with type 2 diabetes and uncontrolled hypertension.Material and methods. Sixty patients were randomly assigned in a 1:1 ratio to the RDN group and the control group. Radiofrequency ablation was performed through the femoral access using a Symplicity Spyral™ renal denervation system (Medtronic, USA).Results. The technical success was 100%. There were no any complications. During the follow-up period, patients in the RDN group showed a significant decrease in the average level of glycated hemoglobin — from 7,9  (6,83-8,35) to 6,85 (6,12-7,10)%  (p<0,001) and basal glycemia — from 9,5 (7,17-10,28) to 7,55 (6,43-8,95) mmol/l (p<0,001) with no significant changes in the control group. Changes in glucose levels and the degree of insulin resistance correlated with a decrease in office systolic blood pressure (r=0,36, p=0,005). After 6-month follow-up period in the RDN group, along with a significant decrease in the HOMA-IR by 1,92 (p<0,001), the average high-density lipoprotein cholesterol level also significantly increased by 0,17 mmol/l (p<0,001), and mean triglyceride level decreased by -0,55 mmol/l (p<0,001).Conclusion. The study results confirm the hypothesis of pleiotropic effects of RDN in patients with comorbid pathology associated with central sympathetic nervous system hyperactivity (diabetes, hypertension, dyslipidemia).

Treatment of patients with combined coronary and carotid artery atherosclerosis is a difficult task due to the increased risk of surgical intervention in this cohort of patients. Lack of timely treatment can lead to a decrease in the quality of life of patients, as well as to death. In some cases with combined coronary and carotid artery atherosclerosis, the choice of surgical intervention may depend on vascular bed involvement. In a case report, open surgery was associated with a very high risk of perioperative complications; so the only way of myocardial revascularization was minimally invasive endovascular surgery. The article presents a case of the treatment of a patient with a combined multivessel coronary and bilateral carotid artery atherosclerosis.
