Acute mesenteric ischemia (AMI) is a rare vascular disease characterized by a high mortality rate with untimely diagnosis and treatment. The overall incidence is low, estimated at 0.09–0.2 % of all hospital admissions to emergency departments. One of the causes of acute mesenteric ischemia is acute arterial thrombosis, which is most common in the elderly.The problem of early diagnosis of acute mesenteric thrombosis is still relevant due to a non-specific clinical features. Computed tomography angiography (CT angiography) of the abdominal aorta and its branches is characterized by high sensitivity (85–98 %) and specificity (91–100 %). Computed tomography angiography is the gold standard for the diagnosis of acute mesenteric ischemia.The article discusses the use of computed tomography angiography (CT angiography) for visualization of acute mesenteric thrombosis.

Takayasu’s disease (non-specific aorto-arteritis) is a chronic, idiopathic, inflammatory disease that primarily affects large vessels, such as the aorta and its major branches, including the pulmonary and coronary arteries. It often develops in women under the age of 50 years. Accurate and early diagnosis plays an important role in the prognosis of life in patients with this pathology. Complaints of  patients with lesions of the aorta and its branches are non-specific in nature and are characterized by fever, night sweats, malaise and arthralgia, passing under the “mask” of other diseases. With the progression of the disease, stenoses or aneurysms occur in the arteries, which leads to ischemia of the limbs and internal organs, manifested by the corresponding clinical manifestations.The article presents the observation of aorto-arteritis Takayasu type V (generalized variant) in the woman of 26 years.

А clinical case of treatment of a patient with isolated saccular aneurysm of the aortic arch and aneurysm of the infrarenal aorta of large size is presented. As a сoncomitant pathology, gastric adenocarcinoma was revealed. Multi-stage surgical treatment was performed. The first stage included left-sided carotid-subclavian bypass, the second –TEVAR, the third — EVAR. The final stage was an extended gastrectomy with lymphodissection. No complications were found during the treatment. The technique of operations is described, explanations on the chosen tactics of treatment are given. The conclusion is made about the advantage of endovascular techniques in the treatment of aortic pathology in patients with oncological pathology.

Background. “Scimitar” syndrome is a rare congenital malformation with a frequency of 2 per 100,000 newborns. The syndrome is manifested by complete abnormal drainage of the pulmonary veins of the right lung into the inferior vena cava. According to the literature, a typical symptom of scimitar syndrome can be detected on radiographs in no more than 1/3 of patients. Only complex radiation diagnostics with the inclusion of multispiral computed tomographic angiography allows to diagnose “scimitar” syndrome, determine all its components, clarify the anatomical features and determine the volume and tactics of further cardiac surgery. Objective of the present clinical case is to assess the role of radiation research methods in the primary diagnosis and control of surgical treatment of scimitar syndrome. Materials and methods. A 39-year-old patient with a history of open arterial duct ligation and complaints of fatigue, shortness of breath arising from household loads was examined. According to the results of the chest x-ray and MSCT angiography of the chest organs, “scimitar” syndrome was diagnosed, the patient underwent a two-stage cardiosurgical treatment with the assessment of the results by MSCT angiography. Results. According to the results of radiation studies, the patient revealed a rare congenital malformation — “scimitar” syndrome. Conclusion. MSCT angiography of the chest is a highly informative, minimally invasive diagnostic method for the scimitar syndrome. MSCT angiography of the chest allows you to visually and accurately visualize the type of abnormal drainage, the course and place of the confluence of the collector, the presence of anastomoses with the left heart, which directly affects the definition of tactics for surgical correction of the disease. MSCT angiography of the chest allows you to evaluate the results of surgical treatment.
