Сравнительная характеристика вариантной анатомии запирательной артерии в зависимости от пола

Abstract

Abstract Background: The obturator artery (OA) is the reason for increased attention for many surgeons as it is the most variable vascular of the vessels of the pelvis. In the specialized literature a. obturatoria divides into “normal” when it starts from the system. iliaca interna, and “atypical” when the obturator artery originates from the system of the external iliac artery (a. epigastrica inferior or a. iliaca externa). About the incidence of “atypical” AO a consensus does not exist. Serious danger a. obturatoria is when she lies on the lacunar ligament, which creates additional difficulties when performing surgery for femoral hernia. Material and methods: Vascular access was performed by performing a full midline laparotomy. A. obturatoria was exposed from its origin to the obturator canal. After that it was installed a version of separation, the length with calipers and diameter. The researches were made from October, 2014 to May,2015. In total 44 corpses (23 men and 21 female) were processed. Conclusions: 1. As a result of researches it was found that the common frequency of “atypical” variants of a. obturatoria for women by 6.2% points more than for men; 2. It is established that a. obturatoria lay on lig. lacunare more frequently in men (16.7%) than in women (10.0 per cent); 3. On female corpses was statistically significant difference between the diameters of the “atypical” OA and OA with a common origin (in this case the values of the diameters of the “atypical” OA exceeded the size of the diameters OA with a common origin).
