Isolated arterioportal fistula presenting with variceal hemorrhage

引用

World Journal of Gastroenterology 2013年第17期19卷 2714-2717页

作者： Anupama Nookala Behnam Saberi Ramon Ter-oganesyan Gary Kanel Phillip Duong Takeshi Saito Division of Gastroenterology and Liver Diseases Department of Medicine University of Southern California Los Angeles Department of Radiology University of Southern California Department of Pathology University of Southern California

We report a case of life-threatening hematemesis due to portal hypertension caused by an isolated arterioportal fistula (APF). Intrahepatic APFs are extremely rare and are a cause of presinusoidal portal hypertension. Etiologies for APFs are comprised of precipitating trauma, malignancy, and hereditary hemorrhagic telangiectasia, but these were not the case in our patient. Idiopathic APFs are usually due to congenital vascular abnormalities and thus usually present in the pediatric setting. This is one of the first cases of adult-onset isolated APF who presented with portal hypertension and was successfully managed through endoscopic hemostasis and subsequent interventional radiological embolization.

Fast-Constructed marine and Port Structures

引用

Journal of Shipping and Ocean Engineering 2019年第1期9卷 8-13页

作者： Doubrovsky Michael Poizner Mikhail oganesyan Virginia oganesyan Anett Odessa National Maritime University Odessa 65029 Ukraine State R&D Institute of marine Transport Odessa 65058 Ukraine Ukrainian Sea Ports Authority Odessa 65026 Ukraine

In order to provide short construction period and to avoid bulky technologies in maritime conditions some rational structures and installation methods are worked out. These methods may be applied for erection of temporary (seasonable) near-shore constructions;they are comparatively cheap and do not involve heavy construction equipment and mechanisms.

Some Innovations for Offshore and Harbor Berths Construction

引用

Journal of Shipping and Ocean Engineering 2015年第3期5卷 115-122页

作者： Doubrovsky Michael Kaluzhnaya Valentina Kaluzhniy Alexey oganesyan Virginia Sea River Ports and Waterways Department Odessa National Maritime University Odessa 65029 Ukraine Odessa Branch Ukrainian Sea Ports Authority Odessa 65026 Ukraine Ukrainian Sea Ports Authority Odessa 65026 Ukraine

Some new innovative constructions and piling technologies for improvement of offshore and port berthing structures are worked out and discussed. The aims of innovations are to decrease required power of construction (in particular, piling) equipment and, correspondingly, to improve environmental situation at the construction site. Another achieved goal is providing long tubular piles installation in hard soils conditions without application of very heavy and powerful driving machines. Worked out solutions are based on two approaches. One of them provides separate loading of driving force on pile"s shaft and pile"s tip concentrating the whole driving force on one of the mentioned parts of the pile. Another approach is focused on prevention of soil plug formation inside of the tubular pile tip facilitating the pile installation process. Also improved anchorage system for sheet piling seafront walls is presented and discussed. All considered innovations are patented and can be used in wide range of marine, offshore, coastal and harbor structures.
