Abstract:

The aim of the study was to define the factors, having influence to results of repeated percutaneous coronary interventions (PCI) such as isolated balloon angioplasty (BA) and BA in combination with rotational atherectomy (RA), used for treatment of stenosis inside stented segments of coronary arteries. 133 patients, submitted to repeated PCI due to development of stenosis in the stented coronary segments, were included in the study. Clinical and angiographic data were registered three times: at time of initial stenting, during repeated PCI and after 18 monthes of follow-up. Repeated PCI were done together with intracoronary ultrasonography. Decrease of neointimal volume and degree of balloon hyperinflation had not any influence on clinical end-points. Cross-luminal area of the vessel was the only significant prognostic facor for success of repeated PCI. Borderline value of the area was 4,7 sq.mm. Combined technique of PCI (BA + RA) had advantages over isolated BA only in those cases, when large cross-sectional lumen area must be achieved. Good clinical results of patients with cross-sectional lumen area >4,7 sq.mm, obtained after repeated PCI, give possoibility not to use additional interventions. If sufficient increase of the vessel lumen area can not be achieved, an active approach to therapy of such patients should be used after PCI.

The only significant beneficial prognostic factor for success of repeated PCA of the stenosed stented coronary segments was area of the vessels's lumen. It did not depend on technique of revascularisation. Such factors, as decrease of neointimal volume and degree of balloon hyperinflation, had not influence on frequency of restenosis and clinical end-points.

Abstract:

The article presents case report of step-by-step treatment of patient with coronary arteries disease (CAD). Male, 47 yrs in 1996 underwent aorto-coronary bypass with making of 7 bypasses. Due to progression of atherosclerotic disease in postoperative perion patient underwent percutaneous transluminal coronary angioplastics (PTCA). Despite of all procedures new coronary arteries and bypasses defeat appeared and restenosis of previously implanted stents was pointed. Patient was treated in different countries (Israel, Germany Japan, Russia) with different methods, including: drug-eluting stents, angioplasty with the help of excimer laser and rotational atherectomy Application of physical and mechanical isolation of hyperplastic intima (excimer laser, rotational atherectomy) did not give significant decrease of restenosis repeat. Implantation of drug-eluting stents also had no effect. Stent-in-stent implantation in case of drug-eluting stent restenosis led to repeated restenosis in this patient.

Thus, restenosis is a serious problem for interventional cardiologists. Any of available interventional methods provide optimum direct results, and the long-term results are even poorer.

Abstract:

Endovascular interventions became widespread for last decade. The directional atherectomy with a SilwerHawk device is one of such methods of possible vascular restoration. This method has some advantages than balloon angioplasty or stenting.

Aim: Was to evaluate the efficiency of directional atherectomy with a SilwerHawk device with iliac arteries disease and arteries of legs disease.

Materials and methods: We have included nine patients with peripheral arterial disease in our study the endovascular directional atherectomy with a SilwerHawk device (EV-3) was performed in all patients. We used different accesses to the artery and protocols of interventions. In all cases we used distal embolic protection device «Spider» (EV-3).

Results: The immediate results of intervention were evaluated. We developed operation algorithms in different cases of vessel disease. The article describes the technical aspects and nuances of work with SilwerHawk device. The perioperative tactics of treatment are also considered in it.

Conclusion: Endovascular atherectomy is a new and effective method in treatment of patients with different peripheral arteries disease. It provides allows considerably to expand the field of methodics application.

Abstract:

Aim: was to improve results of a semi-closed loop endarterectomy from the superficial femoral artery (SFA).

Materials and methods: study is based on results of the examination and treatment of 85 patients with obliterating atherosclerosis of lower limbs, who underwent operations in FGBI «Russian Scientific Center of Radiology and Surgical Technologies» Health Ministry from 2008 to 2012.

All patients included in the study were divided into 2 groups :

• Main group - 30 patients operated on by a combination loop endarterectomy with simultaneous implantation of endovascular stent-grafts in SFA .

• The control group - 55 patients operated on a routine procedure loop endarterectomy .

Patients included in the comparison group were matched by gender, age, comorbidity , stage of ischemia and the outflow channel .

Results: The primary patency of the reconstructed area in the main group at 1 year was 73% after 1 years - 63% , cumulative - 76% at 1 year and 70% at 2 years, the limb is stored in 90% of cases (at 1 and 2 years of follow). Patients in the control group remained SFA patency at 1 year in 43% of cases, after 2 years - 32%.

Conclusion: Post-endarterectomy stent placement in SFA significantly improved results of loop endarterectomy

With a diameter of 8 mm and PBA more loop endarterectomy with implantation of stent grafts is a clinically and economically feasible.
