Objective: Aortic diseases remain an acute and debatable problem. Among all the aortic pathologies, the most dangerous are dynamic aneurysmal expansion, traumatic dissections and / or aneurysms, pure aortic intima dissections. Contemporary and less invasive treatment method is the stent graft implantation into aorta. This report describes the first experience of thoracic endovascular aortic repair (TEVAR) and endovascular aneurysm repair (EVAR) in the Kyrgyz Republic in consecutive patients with life-threatening aortic conditions. Methods: Nine patients, who underwent TEVAR and EVAR, were presented after all clinical examinations, echocardiography and computed tomography angiography with various life-threatening aortic diseases. Among the pathologies there were 2 (22.2%) dissections only, traumatic aneurysm 1 (11.1%), aneurysm without dissection 1 (11.1%), aneurysm with intimal dissection 5 (55.6%). Seven patients with dissection had type B (The Stanford classification). Results: TEVAR was performed in eight cases EVAR just in one. All patients reached the 6-month endpoint. None of the following, such as aneurysm expansion, aneurysm thrombosis or a functioning of false lumen at the sites of the stent graft implantation have been recorded. In addition, no further progression of the false lumen below the implantation zones was visualized. Mean diameter of stent grafts was 31.4 ± 4.8 mm and 188.9 ± 34.6 mm in length. Conclusion: This modest observation showed the effectiveness of stent grafts implantation procedures in various aortic life-threatening conditions, such as aneurysm and / or aortic intima dissection.

We describe a case of guiding catheter induced dissection of left main coronary artery and ascending aorta. A patient with unstable angina and two-vessel disease underwent drug eluting stents implantation in proximal left anterior descending artery and distal left circumflex artery. Six hours after the procedure of acute occlusive dissection of left main coronary artery with spreading to ascending aorta developed, it was required to do stenting of the left anterior descending and left main coronary arteries and balloon dilatation of left circumflex artery. Despite the initial success of the repeated intervention, total occlusion of left main coronary artery occurred with unsuccessful reopening in catheterization laboratory. Emergency coronary artery bypass surgery was carried out. However, despite the patent anastomosis from left mammary to left anterior descending artery, the patient died.

This report describes an extremely rare case of an aorto-right ventricular tunnel originating from the left coronary sinus with abnormality of left coronary artery in the 11-year-old child.

Objective: Pure atherosclerosis and diabetes mellitus are often responsible for the lesion of lower limb arteries. As a result, critical ischemia may develop. Endovascular treatment of lower extremities chronic ischemia in the modern world one of the most effective methods of limbs salvage. This report is an analysis of the first experience of endovascular treatment in consecutive patients with chronic lower limb ischemia in the Kyrgyz Republic. Methods: In 2016-2018, there were 31 patients with chronic lower limb ischemia in IIb-IV Fontaine's stages who underwent endovascular treatment. The primary endpoint was 6-month painlessness or reduction of the Fontaine stage; freedom from amputation up to six months; active regenerative process or full recovery of ulcers/wounds up to six months. The secondary endpoints included 6-month all-cause mortality and reintervention rate. Results: Overall, 27 (87.1%) patients reached painless form (stage I according to Fontaine (ABI ≥0.9)), with complete regeneration or active reparative process observed in 20 (64. 5%) patients. In general, major amputation was avoided in 29 (93.5%) patients (two patients underwent amputation by E. Burgess). Minor amputations were performed below the level of foot dorsum (Sharp) in 35.5% (11 patients). Simultaneous percutaneous coronary interventions and peripheral interventions were performed in 6 (19. 4%) cases. In total, within 6 months one death was registered (3.2%). Conclusion: The first endovascular treatment of consecutive patients showed encouraging 6-month results. Simultaneous («Ad-hoc») or stepwise (at the current hospitalization) procedures on coronary and peripheral arteries ensure safety and can provide more chances of patient`s survival.
