Objective ‒ to analyze the results of surgical treatment of basilar artery (BA) bifurcation arterial aneurysms (AA), taking into account the method of BA obliteration, the type of disease, to summarize the results of surgical treatment of BA.Materials and methods. A retrospective analysis of the results of a comprehensive examination and surgical treatment of 132 patients with AA of BA bifurcation in a group of 387 operated patients with posterior cerebral circulation aneurysms, who were hospitalized and operated in the vascular departments of the State Institution Romodanov Neurosurgery Institute National Academy of Medical Sciences of Ukraine in the period from 1998 to 2019 years is made. Patients were divided into groups according to the type of disease and the method of surgical treatment of AA of BA bifurcation. The analysis of the results of surgical treatment AA of BA bifurcation was performed taking into account the method of  occlusion and the clinical type.Results. The balloon occlusion technique was used in 16 (12.1 %) patients with AA of BA bifurcation, including hemorrhagic and other types of disease. Radical exclusion of AA of BA bifurcation was achieved only in 1 (6.25 %) patients of this group. Exclusion of AA of BA bifurcation at level IIR was also recorded in only 1 (6.25 %) patient. In 4 (25.0 %) patients, the level of AA occlusion corresponded to IIIR. In 10 (62.5 %) patients, after surgery using the balloon occlusion technique, AA of BA bifurcation remained not excluded. Satisfactory functional results of treatment using the balloon occlusion technique, according to mRs, were obtained in 7 (43.7 %) patients of this group, without taking into account the radicality of AA of BA bifurcation exclusion. Transcranial technique, taking into account hemorrhagic and other types of flow, was used in 5 (3.8 %) patients with AA of BA bifurcation. In 4 (80.0 %) patients of this group, radical exclusion from the bloodstream was achieved by clipping (occlusion level ‒ IR). In 1 (20.0 %) wrapping of aneurysm walls were strengthened (occlusion level ‒ AA of BA bifurcation is strengthened). Satisfactory functional treatment results in this group were obtained in 3 (60.0 %) observations. Using modern methods of aneurysm coil embolization, 111 (84.0 %) patients with AA of BA bifurcation were operated. Radical exclusion of AA from the bloodstream at the level of IR was achieved in 40 (36.0 %) patients. The level of occlusion IIR was observed in 48 (43.2 %) patients. In 26 (23.4 %) cases, the level of occlusion corresponded to IIIR. In 1 (0.9 %) case, the aneurysm was excluded at level IIID. Satisfactory functional results, according to mRs, in this group were obtained in 89 (80.2 %) observations.Conclusions. The main method of treatment of AA of BA bifurcation, regardless of the type of disease, should be considered endovascular with the use of modern methods of endovascular obliteration of aneurysm. Methods of transcranial clipping of aneurysms are possible in the surgical treatment of AA of BA bifurcation, but it is advisable to use them when it is impossible to perform endovascular intervention with modern methods of obliteration. The balloon occlusion technique is extremely ineffective in terms of radical shutdown and quality of life of operated patients with  AA of BA bifurcation and can only be considered as a subject of the historical aspect of endovascular treatment of  AA of BA bifurcation.

Purpose. To study the anatomical and functional results of various methods of surgical treatment of idiopathic macular rupture. Material and methods. In the course of this study, 50 medical records of patients with a diagnosis of macular rupture were randomly selected from the total number of those, who underwent the surgery at the Orenburg branch of The S. Fyodorov Eye Microsurgery Federal State Institution for 2020 year. Patients were divided into 3 groups. In the first group (38 eyes), the macular rupture was closed using ACP and PRP, in the second group (7 eyes) – using an inverted flap of the internal border membrane, in the third group (5 eyes) – by mechanical convergence of the edges of the rupture followed by tamponade of the vitreous cavity with silicone oil. Results. To assess the medical efficiency of the studied methods of surgical treatment of idiopathic macular rupture, the rate of increase in the maximum corrected visual acuity (MCVA) was calculated for each patient. Conclusion. The calculated indicator of the dynamics of vision improvement «the rate of BCVA growth» as a whole reflects the positive dynamics of the treatment of idiopathic macular rupture by surgical methods and can be used to assess the medical effectiveness of methods of treating patients with eye diseases initially with different values of the BCVA parameter. In the course of the analysis, no significant differences were found between the influence of various methods of surgical treatment of macular rupture on the rate of BCVA growth or rupture closure. Correlation analysis did not establish a statistically significant dependence of the growth rate of BCVA on the initial size of the rupture. Key words: macular rupture, inverted flap, platelet-rich plasma (PRP), autologous conditioned plasma (ACP).

Balloon Occlusion Technique

The conventional technique for 90Y microsphere treatment planning involves diagnostic angiography with prophylactic embolization of hepatoenteric collaterals to prevent non-target microsphere administration. In some instances, embolization is not technically feasible due to anatomy or the size of the collateral vessel. In lieu of prophylactic embolization, the balloon occlusion technique may be employed. The technique uses a compliant balloon to temporarily occlude the common hepatic artery to induce reversal of arterial flow in various hepatoenteric collaterals (gastroduodenal, right gastric, supraduodenal, etc.). This technique is generally employed in patients with Michaels type 1 anatomy; however, it can also be used in patients with variant anatomy.

A 62-year-old man with a traumatic high-flow right carotid-cavernous fistula was treated by transarterial balloon occlusion technique. However, because of the relatively small size of the fistula, the balloon could not enter into the cavernous sinus via the fistula. During the procedure, the shunt flow decreased significantly, and we stopped the procedure. Follow-up angiography performed 14 days after the procedure showed complete occlusion of the fistula with a small residual pseudoaneurysm. One year later, the pseudoaneurysm had decreased in size. Repeated transient decrease and stagnancy of blood flow at the fistula during the balloon procedure may have played an important role in the thrombosis in this patient.
