[Subclavian artery aneurysms: pathogenesis, diagnosis, and therapeutic decision-making].

The article deals with the relevant literature data concerning diagnosis and treatment of subclavian artery aneurysms. This nosological entity is relatively uncommon, however its importance for modern medicine should not be underestimated. Despite a low incidence of the pathology, it should be understood that the disease's course for the patient is associated with the development of severe complications which may lead to disability or even death.

[Hybrid technologies in treatment of a patient with vascular graft infection].

Presented in the article are advantages of various methods of treatment of periprosthetic infection which continues to be one of the most challenging problems in modern vascular surgery. We describe herein a clinical case report regarding a patient with late infection of a bifurcated aortofemoral bypass graft. The infectious complication manifested itself by a periprosthetic infiltrate in the area of the distal anastomosis.

[Vector mapping of deformation and blood flows in patients with ascending aortic aneurysm].

The authors performed clinical studies based on modelling of an ascending aortic aneurysm in 37 patients and 10 apparently healthy subjects. Echocardiography was carried out in the B-mode using the Vivid E9 device (USA, GE). The linear dimensions of the aorta were assessed at three points - in the immediate vicinity of the valves, in the area of the maximum dilatation and in the area of decreased dilatation with registration of blood flow velocity in the aorta.

[Stagewise hybrid method of treating a patient with connective tissue dysplasia, aortic aneurysm, and distal dissection].

Presented herein is a clinical case report concerning the use of a hybrid technique in stagewise surgical management of a patient with distal dissection and an aneurysm of the thoracoabdominal portion of the aorta. The patient at high risk with the connective tissue dysplasia syndrome had a past medical history of prosthetic repair of the descending thoracic aorta with type-1 haemodynamic correction. Three years later, the findings of computed tomography demonstrated fenestration in the area of the distal anastomosis, a patent false channel, and an increase in the diameter of the unoperated thoracoabdominal portion of the aorta.

[Results of endovascular treatment of patients with type C and D lesions of the aortoiliac segment according to the TASC II classification].

Presented herein are the results of endovascular interventions carried out in patients with occlusive lesions of the terminal portion of the aorta and iliac arteries (types C and D according to the TASC II classification). The study comprised a total of 45 subjects with type C and D lesions. The technical success rate in the group of patients with type C lesions amounted to 100% and in the group of those with type D lesions to 92.

[Endoprosthetic repair of the abdominal aorta in patients with infrarenal aneurysm and unfavourable anatomy of its proximal neck].

Analysed herein are immediate and remote results of endoprosthetic repair of the abdominal aorta in patients with unfavourable anatomy of its proximal neck. Group I (Study Group) was composed of 31 patients with unfavourable anatomy of the proximal neck, the control group (Group II) comprised a total of 52 patients with no unfavourable anatomical factors. The criteria of assessment were as follows: technical success, adequate position of the endograft, frequency of the development of various endoleaks, duration of the operation and hospital stay, lethality in the remote period, and necessity of secondary interventions.

Surgical management of distal aortic dissections.

The authors share herein their experience gained in surgical management of 101 patients presenting with distal aortic dissection, describing in detail surgical policy and the technique of reconstructive interventions on the thoracoabdominal and descending thoracic aorta, with both treatment policy and the technique involved having over the past several years changed considerably. Shown herein is efficacy of the so-called "local" prosthetic repair of the descending thoracic aorta as compared to thoracoabdominal prosthetic reconstruction of the aorta, especially if the former variant is combined with directing blood flow to the true aortic lumen. Repeat and stagewise operations were performed in 17 % of cases, with a lethality rate of 28.

[A relapse, or continuation of varicose disease - that is the question?].

The work was based on the findings obtained by a comprehensive examination and surgical treatment of 217 patients with primary varicose veins of the lower limbs. Depending on the method of operative intervention, the patients were subdivided into two groups. Group One consisted of 115 patients subjected to combined phlebectomy, while Group Two patients (n=102) underwent stem scleroobliteration (SSO).
