Esophageal cancer is the sixth leading cause of death from cancer worldwide. Most patients with esophageal cancer die from relapses or metastases, with a 5-year survival rate ranging from 15% to 25%. The most common places of metastasis are the liver, lungs, bones and adrenal glands. Metastases in the kidney are extremely rare. We present the clinical case of a 61-year-old patient who was surgically radically treated at the A.V. Vishnevsky Surgery Center about esophageal cancer. The lesion was localized in the middle third of the esophagus along the posterior one, with spreading to the right wall, protruding into the lumen, slightly narrowing it. The situation was complicated by the fact that preoperatively the patient was diagnosed with coronary artery stenosis: the middle third of the anterior interventricular branch (AIB) of 80%, the proximal third of the envelope of the left coronary artery to 70%, the right coronary artery in the middle third to 50%. In this connection, the first stage of treatment was performed by stenting of AIB and the envelope of the left coronary artery. With the dynamic observation of the patient's condition, metastasis to the kidney was revealed in two years, and the patient was also operated on. This clinical case demonstrates the possibility of using a complex radiology (including X-ray, ultrasound, MSCT and angiography) at the stages of examination and treatment of such category of patients, allowing timely detection and correction of both the manifestations of the underlying pathology and concomitant diseases.

Bland-White-Garland syndrome (anomalous origin of left coronary artery from the pulmonary artery) is a very rare congenital anomaly, reported in less than 0.5% of all the congenital heart disease which may result myocardial infarction, congestive heart failure and sometimes death during the early infantile period. We report a case with this anomaly, a 27 year old young lady, mother of one child presented with progressive dyspnea and cardiomagaly on X-ray. The diagnosis was made on noninvasive imaging procedure. This lady is now on optimal medications and follow up.Key words: Bland-White-Garland (BWG) syndrome; Left coronary artery (LCA); Pulmonary artery (PA).

AIM. To assess coronary calcification nature in patients with rheumatoid arthritis using digital radiography.METHODS. Chest and distal upper extremities X-ray examination results of the 60 patients with rheumatoid arthritis were retrospectively analyzed. The patients mean age was 54.3±7.8 years, mean disease duration - 8.34±0.3 years. The correlation closeness assessment of qualitative features in the observed group was performed by Pearson correlation coefficient.RESULTS. When performing distal upper extremities X-ray examination, in 9 (15.0±4.6%) patients stage I, in 16 (26.7±5.7%) - II, in 21 (35.0±6.2 %) - III, in 14 (23.3±5.5%) patients - stage IV rheumatoid arthritis was found. In 19 (31.7±6.0%) patients coronary calcifications were visualized in the anterior interventricular branch of the left coronary artery, in 14 (23.3±5.5%) patients - in the circumflex branch of the left coronary artery, in 10 (16.7±4.8%) - in the right coronary artery, in 10 (16.7±4.8%) patients - the main trunk of the left coronary artery. In 7 (11.7±4.1%) patients aortic arch calcifications were found. It was found that the coronary calcifications incidence was higher in more prolonged disease course. Correlation relationship between coronary calcifications and rheumatoid arthritis stage was determined: in 7 (77.8±4.1%) patients with stage I, 14 (87.5±4.8%) patients with stage II and in all patients with stage III and IV coronary and aortic calcifications of various nature were identified. The coronary calcification incidence and prevalence had a direct correlation with the patient’s age: in most cases (66.7±10.3%) patients aged 55-60 years had multivessel calcification (≥3).CONCLUSION. There is a close correlation relationship between coronary calcifications and rheumatoid arthritis stages; coronary calcification incidence and prevalence in patients with rheumatoid arthritis depends on age, as well as the disease duration and stage, which is particularly important in the treatment strategy determination.

Between January 2002 and December 2012, five patients (4 female) underwent corrective surgery for anomalous left coronary artery from pulmonary artery (ALCAPA). They were older than 1 year (range, 3-56 years). One of the 2 patients younger than 10 years had presented with congestive heart failure, and the other had experienced repeated episodes of lower respiratory tract infection since childhood. Of the remaining 3 adult patients, 2 had experienced angina with effort, and 1 patient had had repeated respiratory tract infections since childhood, with mild dyspnea on effort of New York Heart Association (NYHA) class II. Three patients had the anomalous left coronary artery implanted directly into the ascending aorta via coronary-button transfer, and 2 patients underwent coronary artery bypass with obliteration of the left main ostium. Two patients underwent concomitant mitral valve repair procedures, and 1 patient underwent direct closure of a perimembranous ventricular septal defect. Four patients survived the surgery, and 1 patient died because of a persistently low cardiac output. Follow-up times ranged from 3 months to 4 years. All survivors are in NYHA class I and have left ventricular ejection fractions of 45% to 60%, with moderate (n = 1), mild (n = 1), or no (n = 2) mitral insufficiency. We conclude that a few naturally selected patients with ALCAPA do survive beyond infancy and can undergo establishment of 2 coronary systems with satisfactory results.
