[Ultrasound diagnosis in endoprosthesis of lower extremity arterial aneurysms with "Hemobahn"- and "Viabahn"-eluted stents].
The paper presents the results of color duplex scanning (CDS) in 7 patients treated at the Unit of Vascular Surgery, Clinical Hospital No. 83, from 2002 to 2006, in whom 5 Hemobahn grafting stents and 2 Viabahm ones were implanted into the lower limb arterial aneurysms and the proximal anastomoses of the iliofemoral alloshunts "Gore-tex". A grafting stent was individually selected for each specific case. All the examinees were males. The patients' age was 60 to 70 years. The results of endovascular interventions were assessed, by analyzing color duplex scanning (CDS) of a grafting stent implantation area in early postoperative periods (days 1-3), further by the scheme following 1, 3, 6, and 12 months and then twice a year. Endovascular intervention areas were studied by the standard procedure on Logic-500 and Vivid-700 ultrasound apparatuses (USA) with a 7.5-MHz linear transducer and a 3.5-MHz convection transducer. In the postoperative period, multiprojection scanning was used to detect stent configuration impairments. According to the data of examination using the CDS technique, a surgical success was noted in 100% of cases. In all cases, stage, adequate aneurysmal stenting along with the restoration of the geometry of proximal anastomoses of iliofemoral alloshunts, iliac and superficial femoral arteries with exclusion of aneurysms from blood flow was diagnosed at a hospital stage. Follow-up ultrasonography revealed no changes in the area of endovascular intervention. Thus, as a highly informative, noninvasive technique, CDS can assess the results of implantation of grafting stents into the arteries and shunts of the lower extremities in both early and late postoperative periods.
