[Comparison of efficacy of rivaroxaban and warfarin after open operations on the infrainguinal segment]. / Sravnenie éffektivnosti rivaroksabana i varfarina posle otkrytykh operatsii na infraingvinal'nom segmente.

The authors analysed oral anticoagulant agents prescribed in the postoperative period to patients after endured reconstructive operative intervention on arteries of the femorotibial segment. The study included a total of 104 patients subjected to femoropopliteal or femorotibial bypass grafting using an autologous vein or a prosthesis. Depending on the prescribed anticoagulation agent, the patients were subdivided into two groups. Group One patients (n=43) in the postoperative period received rivaroxaban, and Group Two patients (n=61) took warfarin. Efficacy of therapy was evaluated by the frequency of haemorrhage and thromboses in the early and remote postoperative periods. The findings of the immediate postoperative period demonstrated comparable rates of haemorrhagic complications, early thromboses and redo interventions in both Groups (p=0.7). The duration of long-term postoperative period varied from 3 months to 5 years. No statistically significant differences in patency of the performed reconstructions were revealed between the groups. The 3-year primary assisted patency rate in the rivaroxaban group and warfarin group amounted to 89 and 80%, respectively. The incidence of haemorrhagic complications in the postoperative period was insignificant in the studied groups. Hence, rivaroxaban may be prescribed in the early and remote postoperative period to patients who underwent open reconstructive operative intervention on arteries of the infrainguinal zone.

[Results of hybrid loop endarterectomy from the superficial femoral artery with the MultiTASC]. / Rezul'taty gibridnoi petlevoi éndarteréktomii iz poverkhnostnoi bedrennoi arterii petlei MultiTASC.

The purpose of this study was to analyse the results of hybrid loop endarterectomy from the superficial femoral artery (SFA) in its occlusion, preformed in a total of forty-two patients. Of these, 27 patients had prior to the intervention been diagnosed with stage II B ischaemia and 15 patients had been diagnosed as having critical ischaemia. Technical success of the operation amounted to 88%, with the frequency of early thromboses equalling 2.7%. In the early postoperative period, one patient died of acute myocardial infarction. The 1-, 2- and 3-year remote cumulative primary patency rate amounted to 81, 74 and 74%, respectively. There were no amputations performed within the timeframe of the follow-up period. The technique of hybrid loop endarterectomy with the MultiTASC loop followed by stenting of the proximal portion of the popliteal artery in occlusion of the SFA and stenoses of the common femoral artery has proved to be a highly efficient intervention yielding good immediate and remote results.
