[Visceral debranching in hybrid surgery of thoracoabdominal aortic aneurysms].

Presented herein is a review of the literature dedicated to the method of visceral debranching, i. e., switching of the visceral and renal branches of the abdominal aorta to its intact portion, using synthetic vascular prostheses as the first stage of hybrid surgical treatment of thoracoabdominal aortic aneurysms prior to endovascular aortic aneurysm repair.

[Removal of ascending aortic dissection and residual blood flow after transcatheter isolation of descending aortic dissection].

Presented herein is a clinical case report concerning successful simultaneous surgical treatment of a female patient with a complication after transcatheter treatment for chronic dissection of the descending portion of the thoracic aorta. The woman was subjected to elective transcatheter isolation of chronic dissection of the descending thoracic aorta using a stent graft with complete coverage of the zone of the origin of the left subclavian artery. Repeat control imaging studies several months after the intervention revealed residual blood flow through the false channel, directed retrogradely from the distal edge of the stent graft to the left subclavian artery.

[Hybrid treatment of patients with aneurysms and dissections of the aortic arch and descending portion of the thoracic aorta].

The authors share herein their experience with hybrid surgical treatment of 21 patients presenting with lesions of the aortic arch and descending thoracic aorta. Aortic pathology included dissection of the thoracoabdominal aorta (n=15), a sacciform aneurysm of the aortic arch (n=5), and a spindle-shaped aneurysm of the distal portions of the aortic arch (n=1). The first stage consisted of the following operations: transposition of the left subclavian artery into the left common carotid artery (n=9; 42.

[Functional properties of smooth muscle cells in ascending aortic aneurysm].

Thoracic aortic aneurism (TAA) develops as a result of complex series of events that dynamically alter the structure and composition of the aortic vascular extracellular matrix (ECM). The main elements that alter the composition of aortic wall are smooth muscle cells (SMC). The purpose of the present work was to study alteration of smooth muscle cell functions derived from the patients with TAA and from healthy donors.

[Informational function of heart and its apply if diagnostics of medical disease].

Biophysical properties of the electric, magnetic and hydrodynamic impulses generated by the heart suggest the existence of the informational function of the heart: the ability to apply impulses across the body; probable variability of their main parameters, the presence in the heart of the amplitude and frequency-phase modulation carries the information into the cardiosignls. The main tenets of the theory of information functions of the heart are implemented in the technology of informational analysis of electrocardiosignals based on encoding--transformation of the probable variability of parameters electrocardiosignals into the code text. Specific sets of combinations of symbols of norm and rules of internal diseases were indentified.
