- Аннотация: Introduction & Objectives: Arteries of the small pelvis can have a complex anatomy, different variants of discharge, as well as anastomoses withother branches of the internal iliac artery (VPA). This explains the technical complexity of identification and catheterization of prostatic arteries (PA),as well as the possibility of complications associated with non-target embolization of prostatic artery anastomoses.Materials & Methods: The study included 168 patients treated from 2013 to 2021. For catheterization of the prostatic arteries, 4-5 Frmicroconductors and 2-2.8 Fr microcatheters were used. For embolization, hydrogel microspheres with a diameter of 100–300 μm and 300–500 μmwere used, as well as PVA microparticles with a diameter of 100–500 μm. At the preoperative stage, MSCT angiography of the pelvic organs wasperformed to determine the type of angioarchitectonics of the prostate. Microdoses of vasodilators and blockade of anastomoses using embolizationcoils were used to prevent non-target embolization.Results: The use of preoperative MSCT angiography in combination with intraoperative digital subtraction angiography made it possible todetermine the variant of prostatic artery divergence and identify their anastomoses in 100% of patients (336 pelvic sides). One prostatic artery wasdetected in 91.4% (307) of the pelvic sides, two independent PAs in 8.6% (29) of cases. Symmetrical variant of the divergence of the prostaticarteries on both sides was detected in 14.3% (24) patients, the remaining 85.7% (144) patients showed asymmetry on both sides. The absence ofanastomoses of the prostatic arteries was detected in 75.5% (254) of the pelvic sides, and in 24.4% (82) of the pelvic sides, anastomoses weredetected. Interlobar intraprostatic anastomoses were found in 10.1% (34) of the pelvic sides, communication with a. dorsalis penis was detectedin 8% (27) of cases, with rectal arteries in 5.3% (18) of the pelvic sides and with urinary bladder arteries in 3.6% (12) of cases. Based on the dataobtained, measures were taken in 52 cases (30.9%) to prevent non-target embolization, the use of which was effective in 48 patients (92.4%).Conclusions: Superselective embolization of the arteries of the prostate is a modern minimally invasive method for treating prostatic hyperplasiawith a high safety profile. The pelvic arteries have an extremely complex anatomy, different variants of discharge, as well as anastomoses with otherbranches of the internal iliac artery, which complicates the implementation of superselective embolization of prostatic arteries. The combination ofpreoperative MSCT and intraoperative digital subtraction angiography makes it possible to identify the prostatic artery and its anastomoses in mostcases, thus avoiding non-targeted embolization and improving treatment results.Abstracts EAU22 – 37th Annual EAU CongressEur Urol Suppl 2022;81(S 1):S1055
