[A clinical case of successful combination of endovascular and surgical correction of multifocal atherosclerotic signs in an elderly patient].

Combination of the methods of interventional cardioangiology with current techniques of vascular surgery allows a considerable broadening of the potential for the treatment of different signs of multifocal atherosclerosis in "high risk" patients. For instance, a 70-year-old patient (height 152 cm, weight 32 kg; initial concentration of serum creatinine 174 mumol/l) with the clinical evidence of progressing angina pectoris and critical ischemia of the lower extremities underwent angioplasty (the first stage) using a transradial access and stenting of the critically narrowed circumflex branch of the left coronary artery and angioplasty of the proximal segment of the right coronary artery. Good angiographic and clinical results were obtained.

[Dye with low specificity to nucleotide sequences of DNA: use for assessing the quantity of oligonucleotides, immobilized in cells of biological microchips].

To assess the DNA amount in samples (e.g., in biological microchip gel pads) by means of fluorescent dyes, one should use the dyes whose fluorescence weakly depends on DNA composition and structure.

[New aspects of the surgical treatment of aortic coarctation].

The article substantiates the urgency of the problem and shows the results of surgical treatment of coarctation of the aorta in 103 patients who were operated on in the recent 5 years. The operation of choice was resection of the coarctation with the formation of an end-to-end anastomosis (90.3% of operations).

[A new method of surgical treatment of recurrent aortic coarctation (aorto-aortic shunting from the ascending to the descending thoracic aorta)].

The authors discuss the immediate results of 44 reconstructive operations performed for a second time on the descending thoracic aorta for complications of operative interventions conducted earlier for coarctation of the aorta. The high operative risk is connected with difficulties of rethoracotomy and the need to compress the thoracic aorta for a lengthy period of time. Operation for aorto-aortic shunting through right thoracotomy made it possible to avoid these difficulties.

[Surgical treatment of post-anastomosis aneurysm developed after reconstructive operations on the thoracic aorta].

Twenty-three patients were examined and operated on for aneurysms of anastomoses which formed after reconstructive operations on the thoracic aorta for its coarctation (15), kinking of the arch of the aorta (4), traumatic aneurysms (2), nonspecific aortoarteritis (1) and dissecting aneurysm (1). The involved segment had to be repaired with a prosthesis in all operations carried out for the second time. In 30% of patients the course was complicated (aortopulmonary fistulas, false aneurysm with dissection of the descending thoracic aorta).
