[Comparison of results of elastography with hormonal and metabolic status in patients with the diagnosis of thyroid neoplasms].

In order to assess the effectiveness of compression elastography of the thyroid gland as a method for differential diagnosis to studies conducted in the pre-operative period, there were involved 34 patients with a mean age 46.6 +/- 2.7 years.

[Evaluation of coronary bed function by positron emission tomography using 13N-ammonium during cold stimulation].

The purpose of the present investigation was to study the time course of changes in myocardial blood flow (MBF) in response to cold stimulation. Thirty-eight patients having risk factors of cardiovascular complications were examined. The time course of MBF changes was estimated by positron emission tomography (PET) using 13N-ammonium at rest and during a cold test (CT).

[Direct results of endovascular prosthetics of aneurysms of the infrarenal part of the aorta in patients with a severe concomitant pathology].

From May 2007 to March 2009 under observation there were 58 patients aged from 52 to 79 years (mean age 68) with the diagnosis of abdominal aortic aneurysm (AAA). Selection of patients for endoprosthesis was performed by the data of spiral computed aortography. The endovascular exclusion ofAAA from blood flow was performed in 15 patients.

[Modern diagnostic technologies in determination of the strategy of treatment of patients with obliterating atherosclerosis of the lower artery vessels].

The authors analyzed results of surgical treatment of 332 patients in whom 410 reconstructive operations were performed on the lower extremity arteries. During 12 months after operation on the aorto-femoral segment with high peripheral vascular resistance reocclusions were noted in 61% of the cases, with normal resistance--in 11.8%, after operation on the femoro-popliteal segment--in 77.
