<p><strong>Aim.</strong> The aim of this study is to show the outcomes of an open intervention on the ascending aorta and arch combined with stenting of aorta in type I aortic dissection.<br /><strong>Methods.</strong> 6 patients with type I aortic dissection underwent implantation of Djumbodis® Dissection System bare stents at I.M. Sechenov First Moscow Medical University’s Aortic and Cardiovascular Surgery Clinic. In 4 patients, aortic stenting was combined with ascending aorta replacement, in 1 patient, hemiarch ascending aorta and arch replacement was performed and in 1 patient aorta and arch replacement was complemented with a Sun procedure.<br /><strong>Results.</strong> Total operation time, cardiopulmonary bypass time, cross clamp time and hypothermic circulatory arrest time were just similar to those performed in conventional open surgery. There were no intraoperative deaths in this series. 30-day mortality was 16.7 % (1 patient). The patient died because of progressive respiratory and cardiovascular failure, encephalopathy, and gastrointestinal bleeding. 1 patient had acute renal failure and left leg ischemia because of the false lumen thrombosis, 1 patient suffered from cardiac tamponade and 1 patient underwent prolonged mechanical ventilation. Total false lumen thrombosis developed in 1 patient, 4 patients had partial false lumen thrombosis, and in 1 patient the false lumen remained patent.<br /><strong>Conclusion.</strong> Stenting of aortic arch and descending aorta is a good alternative to aortic arch replacement in type I aortic dissection. It promotes stabilization of false and true lumen diameters and global aortic diameter.</p><p>Received 18 October 2016.

The modern approach to the correction of aortic dissection involves the most complete reconstruction of the entire pathologically altered segment of the vessel, which is often impossible due to the vastness of the lesion and the associated severity of surgery. Reduction of intraoperative trauma can improve survival in the immediate postoperative period, and the completeness of reconstruction to reduce the number of complications and relapses in the long term. In this chapter, the methods of reconstruction of the aorta in case of distal dissection from a conventional open surgery to endovascular techniques, or usage of their combination for minimization of surgical trauma, are reviewed.

We describe a case of post-traumatic aortic dissection in a patient 44 years old, whose circular rupture intima immediately below the left subclavian artery led to tamponade the true lumen of the aorta to the narrowing of its lumen to 6 mm in the upper third of the thoracic aorta. Patient underwent implantation of bare metal stent percutaneously which allowed fully straighten the intima and restore the true lumen of the aorta. Study one year after the intervention show the patient's condition is satisfactory, according to the MSCT data the diameter of aorta is not increased, the stent configuration fully corresponds to the contour of the true lumen of the aorta, there is no dissection. Stenting in traumatic aortic dissection is a safe and effective intervention and can be used as monomethod.

The aim. To evaluate the immediate outcomes after complete single-stage or step-by-step reconstruction of the primary and secondary distal aortic dissection using implantation of bare metal stents in the thoracoabdominal aorta.Materials and methods. A prospective study was performed involving 21 patients (19 male) with aortic dissection: 8 had secondary distal dissection (group 1) and 13 had primary distal dissection (group 2). In all patients, indications for intervention were signs of malperfusion in one or more vascular regions. The following factors were evaluated: 30-day survival after surgery, causes of fatal outcomes, frequency and characteristics of non-fatal complications.Results. The average age in group 1 was 43.0 ± 3.1 years, in group 2: 56.0 ± 3.9 years (p < 0.05). The most common cause of dissection in group 1 was connective tissue dysplasia, in group 2 – atherosclerosis in combination with arterial hypertension (p < 0.05). In group 1, 1 (13%) lethal outcome was registered, in group 2 – 4 (31%), the difference between the groups was not significant. Lethal complications were: multiple organ failure, stent implantation in the false aortic canal, aortic rupture, and thrombosis of the superior mesenteric artery. Non-fatal complications developed in group 1 in 3 (38%), in group 2 – in 3 (23%) patients, the difference between the groups is not significant. Among the non-lethal complications, malperfusion of the upper and lower extremities was diagnosed, requiring stent placement, prosthetics or bypass surgery; cerebrospinal circulation disorder, acute cerebrovascular accident, multiple organ failure, conservatively treated.Conclusion. The survival rate for 30 days after a complete single-stage or step-by-step reconstruction of the primary and secondary distal aortic dissection using implantation of bare metal stents in the thoracoabdominal aorta is 76%, the frequency of non – fatal complications is 28%.
