Relevance.Ectopic (extrauterine) pregnancy (EP) occupies a leading place in the structure of urgent gynecological morbidity. This pathology poses a threat to the health and life of a woman, being one of the leading causes of maternal mortality during pregnancy during the first trimester. Among emergency gynecological operations, surgical interventions for EP make up about 50%, and in recent years, most operations have been performed by the laparoscopic method. However, up to now, the pathomorphological changes in the fallopian tubes in patients with EP remain poorly understood.Purpose of the study. To study the features of pathomorphological changes in the fallopian tubes in women with tubal pregnancy, operated on by the laparoscopic method, to substantiate the volume of surgery in patients with this pathology.Material and methods. Morphological examination was performed in 100 women operated on for tubal pregnancy using the laparoscopic method. A comprehensive morphological study of the fallopian tubes removed during the operation was carried out.Results and discussion. The implantation of the ovum in the fallopian tube led to significant changes in its macro- and microstructure, which were caused by the invasion of chorionic villi and involved all layers of the tube wall, differing only in the depth of penetration and prevalence. The anatomical features of the structure of the fallopian tubes contributed to the deep invasion of the ovum into the myosalpinx and subserous parts of the tube, creating the possibility of wall rupture in this area.Conclusions. 1. In all cases of ectopic pregnancy, implantation of the ovum was accompanied by invasion of cytotrophoblast and syncytiotrophoblast, and it involved all layers of the tube wall, differing only in depth and prevalence. The invasive properties of the cytotrophoblast lead to the development of pronounced degenerative changes in the tube wall, which leads to functional inferiority of the tube after the onset of tubal pregnancy in it.2. The chronic productive endomyosalpingitis diagnosed in most patients with ectopic pregnancy with deformation of the tube lumen against the background of changes in the tube wall caused by cytotrophoblastic invasion is an indication for tubectomy. Performing organ-preserving operations on an anatomically and functionally altered fallopian tube is impractical, since it is a high risk factor for recurrent tubal pregnancy in this tube.
Relevance. Ectopic pregnancy is an urgent condition which may lead to intraabdominal hemorrhage and woman death. In recent years, the frequency of this pathology is significantly increasing. However, morphological changes in the fallopian tubes in patients with this disease remain understudied. Aim. To study morphological changes in the fallopian tubes in patients with ectopic pregnancy with various variants of the clinical course. Materials and methods. The morphological study included 130 patients who had laparoscopic surgery for ectopic pregnancy. Comprehensive morphological study of the fallopian tubes removed during surgery was conducted. Results and discussion. The article presents the morphological changes in the fallopian tubes in patients with ectopic pregnancy. Implantation of a fertilized egg in the fallopian tube led to significant changes in its macro- and microstructure, which were due to invasion of the chorionic villi and involved all layers of the tube wall, differing only in depth and prevalence. The most pronounced morphological changes in various segments of the tube were revealed in the endosalpinx. Conclusion. The combination of morphological changes in different layers of the tube is related to a chronic non-specific productive endomyosalpingitis with luminal deformation, which was one of the main causes of this disease development.
Individual features of the blood supply to the uterus and ovaries in 20-25% of cases cause failures in endovascular treatment of patients with uterine leiomyoma (ULM) and are forced to return to traditional surgical methods. The purpose of the study is to assess the possibilities of preventing iatrogenic complications of endovascular treatment of ULM through the use of separating occlusion of the uterine arteries, taking into account the characteristics of the blood supply to the uterus and ovaries. Materials and methods. The work is based on the analysis of the results. X-ray endovascular occlusion of the uterine arteries for ULM performed in 88 women aged 34-46 years (mean age 38.8 ± 2.5 years). The patients were divided into 2 groups: the 1st group comprised 65 patients without visible uterine-ovarian interarterial anastomoses. They performed standard embolization of the uterine arteries (EUA) using spherical PVA microemboli (COOK, USA), Embosphere (Merit Medical, USA) with a diameter of 500-700 microns. The second group consisted of 23 patients in whom utero-ovarian inter-arterial anastomoses were detected. In patients of this group, EUAs were produced with Embox cylindrical emboli (Plastis-M, Russia) with a length of 10 mm and a diameter of 500-700 μm, which occlude only the bed of the uterine arteries and are not capable of to overcome utero-ovarian inter-arterial anastomoses. In the 2nd group of EUA patients wore the character of occlusion, separating the uterine and ovarian arteries. The original EUA protocol was applied, which includes, in addition to the standard stages of selective arteriography of the uterine arteries, performing preliminary abdominal aortography to visualize the ovarian arteries and pelvic arteriography to assess pelvic vascular anatomy and identify utero-ovarian interarterial anastomoses. The results of the study. A total angiographic examination of the ovarian and uterine arteries, including a review angiography of the infrarenal section and bifurcation of the aorta, ileal vessels. In 23 (26.1%) patients with angiographic examination, uterine-ovarian arterio-arterial anastomoses. In 13 patients (56.5% of the detected anastomoses), these were type 1 anastomoses. In 10 patients (43.5% of the detected anastomoses), type 3 anastomoses were detected. Endovascular occlusion of the uterine arteries was performed in all patients. In 5 (7.69%) patients from the 1st group after EUA, amenorrhea occurred. In contrast, in all 23 patients from the 2nd group in the postembolization period, no observation of ovarian function was observed in any of the observations. Conclusion. For endovascular treatment of ULM in the presence of pronounced utero-ovarian interarterial anastomoses, the method of separating uterine artery occlusion is a safe and effective way to prevent ischemic damage to the ovaries.
