A well defined lung mass with clear margins and no other signs such as lymphadenopathy, pulmonary infiltration, consolidation, collapse or bone involvement usually indicates a benign lesion, whether a tumour such as an adenoma (carcinoid), cyst or vascular abnormality. Bronchogenic, pericardial and hydatid cysts do not show contrast enhancement, adenomas do enhance but not as significantly as v...

A 34 months-old male patient with double inlet right ventricle with nonconfluent pulmonary arteries who underwent successful extracardiac fenestarated Fontan procedure using pre-designed T-shaped PTFE vascular graft after multi-step rehabilitation of the diminutive hilar pulmonary arteries. At first we performed 6 mm confluent pulmonary artery vascular graft implantation with 4 mm BT shunt at p...

The purpose of this study was to visualize the spatial patterns and connection of channels created after percutaneous transmyocardial revascularization (PTMR) in normal porcine hearts, and to estimate the relative contributions of transmyocardial and coronary perfusion. Six pigs underwent PTMR creating channels using radiofrequency ablative energy. Three-dimensional computed tomography imaging ...

Purpose of the study. To reveal relationship between serum concentration vascular endothelial growth factor and structural functional state myocardium in patients post-infarction period at stage rehabilitation. Materials methods. We examined 94 outpatient rehabilitation after ad hoc stenting 6 weeks myocardial infarction, 10 healthy volunteers without somatic pathology. All participants study u...

STUDY DESIGN A descriptive cadaveric study measuring arterial tension. OBJECTIVE Anterior lumbar surgery is technically challenging due to perioperative vascular complications. Many studies suggest approaches based on the anatomy of the abdominal vessel for safe vascular mobilization. However, the tension in the vascular structure is also important for adequate exposure of the target lesion. ...
