Abstract:

Surgical treatment of aortic valve pathology is an actual problem of modern medicine. Aortic valve pathology is widely spread in population on a stable high level. Due to a large amount of patients with no possibility of open surgical treatment of aortic valve pathology modern hybrid methods of treatment, such as transcatheter aortic valve implantation are being actively proposed and modified.

MSCT angiography before transcatheter aortic valve implantation is obligatory procedure. Data obtained by MSCT is extremely necessary to define the possibility and the access path of transcatheter aortic valve implantation. MSCT allows to select the size and type of aortic valve prosthesis.

Appearance of modern MSCT scanners with 320-640 row of detectors will increase the leading role of MSCT in preoperative inquiry of patients with planned transcatheter aortic valve implantation.

Abstract:

In this study we have analyzed early and long-term results of endovascular abdominal aneurysm repair (EVAR) in the Department of cardio-vascular surgery of «Russian Cardiology Research anc Production Complex».

Material and methods: research includes 164 patients (February 2009-November 2015) with abdominal aortic aneurysm (AAA), who underwent endovascular abdominal aneurysm repair (EVAR), also with difficult anatomy Patients were operated with basic methodics and also hybrid techniques («chimney», «octopus», fenestrated and branched devices).

Results: 30-day mortality rate accounted for 1,2%, all mortality was 3%.

Abstract:

Backgroud: endovascular implantation of the aortic stent-graft is a method of choice in treatment of aneurysms of the infrarenal abdominal aorta, especially in patients with high surgical risk.This strategy is characterized as less in-hospital complications, shorter in-hospital stay All these circumstances show some advantages of endovascular treatment compared with traditional «open» surgery. Besides that, there are some limitations for aortic endoprosthesis implantation, including short or conical proximal neck, severe angulation of aneurysmatic neck and tortuosity of arteries, insufficient diameter of iliac-femoral segment arteries for stent-graft delivery

Materials and methods: we report two clinical cases of successsful implantation of novel stent-graft OVATION PRIME in patients with adverse anatomy, precisely small diameter of crossing profile and original technology of proximal fixation of endoprosthesis.

Results: the use of innovative models of stent-grafts allows to proceed aortic endoprosthesis implantation with minimal risk of complications in certain patients with adverse vascular anatomy, who were previously deemed unsuitable for endovascular treatment.
