Aim. To present the immediate results of the assessment of the effectiveness and safety of the use of endovascular technologies for the treatment of hemorrhagic complications of pseudoaneurysms of the visceral branches of the abdominal aorta, to offer organizational technologies for the provision of medical care to patients with gastrointestinal bleeding associated with pseudoaneurysms of the visceral arteries. Methods. Endovascular image-guided treatment was performed in 12 patients with pseudoaneurysms of the branches of the celiac trunk. Mean age 546.6 years, patients were hospitalized urgently due to ongoing or recurrent gastrointestinal bleeding, severe anemia, with blood hemoglobin level of 80 g/l. The diagnosis of pseudoaneurysm of the visceral artery was established by computed tomography-angiography. The sizes of pseudoaneurysms varied from 12 to 54 mm in diameter. Endovascular surgery was performed on the first day of hospitalization. In all cases, the stent-graft was implanted into the gastrointestinal or splenic artery into pseudoaneurysm ostium. The average follow-up period was 352.2 days. Results. Endovascular surgery was performed 286.3 hours after making a diagnosis, 2 hours after in-hospital admission. The effectiveness and safety of endovascular treatment was 100% and included stopping the ongoing gastrointestinal bleeding and prevention of its recurrence. Hospital stay of patients was 5 days. The effectiveness stent-graft implantation was confirmed by control angiography. There were no hemorrhagic and embolic complications during follow-up. Conclusion. Endovascular image-guided treatment and prevention of gastrointestinal bleeding in patients with pseudoaneurysms of the branches of the celiac trunk is an effective and safe method; it is necessary to further improve the organization of endovascular care in order to make it more available to the population and to provide effective care in time in case of development of life-threatening diseases and complications.

In Situ Repair

A mycotic aneurysm that also involves the visceral arteries is a life-threatening condition. Surgical management typically consists of débridement and in situ repair with a Dacron graft and reimplantation of the involved visceral branches. We report a rare case of a mycotic saccular thoracoabdominal aortic aneurysm involving the celiac artery, with Streptococcus pneumoniae as the responsible organism. Successful repair of the aneurysm and concomitant revascularization of the celiac artery were achieved.

Saturn's Rings

ABSTRACTA mission to rendezvous with the rings of Saturn is studied with regard to science rationale and instrumentation and engineering feasibility and design. Future detailedin situexploration of the rings of Saturn will require spacecraft systems with enormous propulsive capability. NASA is currently studying the critical technologies for just such a system, called Nuclear Electric Propulsion (NEP). Electric propulsion is the only technology which can effectively provide the required total impulse for this demanding mission. Furthermore, the power source must be nuclear because the solar energy reaching Saturn is only 1% of that at the Earth. An important aspect of this mission is the ability of the low thrust propulsion system to continuously boost the spacecraft above the ring plane as it spirals in toward Saturn, thus enabling scientific measurements of ring particles from only a few kilometers.
