[Contrast-enhanced ultrasonographic study in patients with lower limb arterial lesions].

Background: The introduction into clinical practice of contrast-enhanced ultrasonographic examination made it possible to assess patency of tibial arteries and perfusion of crural muscles in patients with occlusive lesions of lower-limb arteries. These findings are important for planning optimal treatment policy and assessing efficacy of operative or medicamentous treatment.

Objective: The study was aimed at investigating a possibility of contrast-enhanced ultrasound examination for assessment of patency of tibial arteries and quantitative assessment of perfusion of crural muscles in patient with occlusive lesions of lower-limb arteries.

[Use of an ex vivo technique in a patient with renal arteriovenous malformation in complication endovascular treatment].

Renal arteriovenous malformation is a rarely encountered disease characterized by the presence of a direct arteriovenous shunt between the renal artery and vein. This nosology was first described by Varela in 1928, and by 1997 the number of such cases amounted to slightly more than 200. Endovascular closure of a fistula seems to be an attractive method of treatment in view of low traumaticity and a short period of rehabilitation.

[Risk factors for aerostasis failure in case of lung resection].

The results of risk factors analysis of aerostasis failure in 141 patients are presented in the article. All patients were operated in the A.V.

[Diagnosis of neuroendocrine neoplasms of the pancreas].

The rare clinical case of multiple primary gastrointestinal stromal tumors (GIST) in one patient is presented in the article. The analysis of the available material confirmed that there is the problem of early detection of this type of tumors and their differential diagnosis. The minutes of outpatient radiological methods of research should include methods of identifying GIST in various locations.
