    A Meta-Analysis and Systematic Review of Anatomical Variations in the Drainage Pattern of the Azygos Venous System
    Author(s): Mihretu Dessie Jegnie* and Girma Seyoum

    Introduction: The azygos venous system drains blood from the upper lumbar region of the abdomen and thoracic wall. It includes the azygos vein laying on the right and its left side counterparts, the hemiazygos, and accessory hemiazygos veins. The azygos vein receives all the right side posterior intercostal veins. The hemiazygos and accessory hemiazygos veins empty into the azygos vein after receiving the left side posterior intercostal veins. The azygos venous system shows variable drainage pattern in the posterior thorax. Objective: The main aim of this systematic review and meta-analysis was to determine the pooled prevalence of each of the azygos venous system drainage pattern types. Method: PubMed, Scopus, Science Direct, and Google Scholar were searched extensively. The prevalence of each drainage pattern and other relevant data were extracted and organized in a Microsoft Excel .. Read More»
