ABSTRACT
OBJECTIVE: Aim: To analyze the embolic migration complication during arteriovenous malformations (AVMs) embolization of the head and neck localization, and to demonstrate the possibility of tromboaspiration method in treatment of such complications in cerebrovascular region. PATIENTS AND METHODS: Materials and Methods: The endovascular intervention was performed in 116 patients with AVMs of the head and neck localization. We used a superselective catheterization of the external cerebral artery branches as a treatment method of AVMs embolization. During embolization of AVMs, the spherical and not spherical polyvinyl alcohol (PVA) emboli were implanted. RESULTS: Results: The result of treatment was technically successful in 112 (96,6 %) patients with AVMs of the head and neck localization. There were 4 (3,5 %) cerebrovascular complications during AVMs embolization of the head and neck localization. In 2 cases a cerebrovascular complication arose during the AVMs embolization of head localizations. In those 2 cases the cerebrovascular complications were successfully treated conservatively. In other 2 cases cerebrovascular complications arose during the AVMs embolization of neck localizations. One patient died as result of a massive ischemic stroke in the vertebrobasilar zone. Another patient was successful treated by tromboaspiration method. CONCLUSION: Conclusions: Any surgical intervention on the carotid arteries, including endovascular surgery, is associated with a risk to the health and life of the patient. A thorough angiographic diagnosis of the external and internal carotid and vertebral arteries is necessary before endovascular embolization. Modern endovascular technology, such as tromboaspiration, may be helpful to avoid embolic migration complication in cerebrovascular region.

OBJECTIVE: Aim: To evaluate the effectiveness of PSAE for secondary prevention of VB episodes in patients with chronic liver disease (CLD) and CSPH. PATIENTS AND METHODS: Materials and Methods: One hundred twenty patients (from 2008 to 2020) were submitted of PSAE as secondary prevention treatment. The results of the treatment of 27 patients between 2008 and 2012 (first period) were compared with those of 93 patients treated with PSAE since 2013 (second period), as procedure and management protocol were modificated. VB recurrence rate and mortality (related and non-related to bleeding episodes) were defined as study end-points in both groups at 12-months follow-up. RESULTS: Results: At 12-months follow-up, 11 (40,7 %) and 54 (58,1 %) patients in groups 1 and 2, respectively, were free from VBs (p=0,129). Overall mortality rate was significantly higher in group 1, as compared to group 2: 10 (37,0 %) versus 6 (6,4 %) patients, respectively (p<0,001), - due to higher frequency of fatal VB events (7 (26,0 %) vs. 3 (3,2 %) patients, respectively; p=0,001). CONCLUSION: Conclusions: PSAE is an effective treatment for secondary prevention of VB in patients with CLD and CSPS. The management protocol modification resulted in the decrease in overall mortality rate and mortality related to recurrent VB episodes.

OBJECTIVE: The aim: To analyze the results of endovascular revascularization of the femoropopliteal segment using drug-eluting stents. PATIENTS AND METHODS: Materials and methods: Endovascular intervention was performed in 23 patients with occlusive-stenotic lesions of the superficial femoral artery (SFA). Paclitaxel-eluting stents were used. There were 16 (69.6%) patients with diabetes mellitus type 2 and diabetic angiopathy, and 7 (30.4%) patients had obliterating atherosclerosis of the arteries of the lower limbs. Critical ischemia of the lower extremities was diagnosed in 18 (78.3%) cases, and intermittent claudication - in 5 (21.7%). RESULTS: Results: Twenty (86.6 %) scheduled procedures for stenting of the SFA were technically successful. During follow-up period (3 months), there were no cases of reocclusion or clinically significant restenosis at the stented level. There were no "major" amputations during follow -up period. "Small" ankle amputations were performed in 7 (35%) patients with diabetic gangrene. CONCLUSION: Conclusions: Implantation of drug-eluting stents is an effective method of endovascular revascularization in patients with SFA lesions. To compare the results of implantation of drug-eluting stents with other methods of revascularization of the lesions of the femoro-popliteal segment, it is necessary to accumulate more data and increase the duration of the follow-up period.
