Objective-to assess endovascular stenting (ES) of the iliac veins in the treatment of the May-Thurner syndrome (MTS) in patients with pelvic congestion syndrome (PCS) and varicocele. Material and methods. Endovascular stenting of the iliac veins was performed in 7 female patients PCS and 1 male patient with varicocele. All patients underwent duplex ultrasound and computed tomography of the pelvic veins, as well as pelvic phlebography. Self-expanding stents were inserted in all cases. Pelvic pain was assessed by visual-analogue scale before and 4 to 7 days after procedure. Results. Technical success, i.e. restoration of normal patency of the left common iliac vein, was achieved in 8 patients. In 2 patients, stent was displaced towards the inferior vena cava (IVC), which required implantation of a second stent using the stentin-stent technique. Dislocation of the stent into the IVC at 6 months after the intervention was found in 1 patient, but did not result in any complications during further follow-up. All the patients reported reduction of pelvic pain within 4 to 7 days after procedure. The PCS severity score was decreased from 7.2±1.3 to 6.2±0.4 at 1 month after the procedure. However, no further decrease was observed in female patients. At 1 month after ES, the male patient noted a complete disappearance of discomfort in the left inguinal region and left testicle during and after intercourse. Conclusion. Stenting of common iliac vein in patients with MTS leads to decrease of pelvic pain in patients with PCS.
—The work considered an integrated approach to the study of deep-lying Riphean strata of the Buolkalakh–Lena region, which have certain prospects in terms of oil and gas potential. The method of revision and synthesis of acoustic and density logs is described in detail using the example of wells drilled in 80–90 for the purpose of correct reference to seismic sections. It has been shown that the Khaipakh, Debengdin, Arymas, Kyutingdinsky, and Sygynakhtakh formations of the Early and Middle Riphean eras overlook the pre-Permian surface in the middle part of the Lena–Anabar trough. The region also developed older Riphean deposits that are not exposed on the Olenek uplift and are not studied by deep drilling. The prospects for the oil and gas content of Riphean strata in the region are mainly associated with carbonate reservoirs formed in the top of the Riphean sequence and cropping out on the pre-Permian erosive surface, the most promising rocks are those constituting large carbonate platforms that were partially eroded and subjected to processes of hypergenesis and karst formation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
