Long-term outcome after Talent endograft implantation for aneurysms of the abdominal aorta: a multicenter retrospective study.

Background: The development of newer-generation endografts for the endovascular treatment of abdominal aortic aneurysms has resulted in considerable improvements in clinical performance. However, long-term outcome data are still scarce. To assess long-term clinical and radiographic outcomes after use of the Talent stent graft, a retrospective analysis was performed that was based on 165 patients treated with this endograft in Germany between October 1996 and December 1998.

Incidence of renal infarctions after transrenal stent placement in an animal model.

Purpose: To evaluate the incidence and appearance of renal infarctions after transrenal stent placement in an animal model.

Methods: An aortic stent was placed via a femoral approach in 20 female Merino sheep. Ten animals had intentional coverage of one renal ostium with the bare struts, 1 sheep had both renal artery ostia covered, and the other 9 sheep had no stent impingement on the renal orifices.

[An unusual foreign body in the upper gastrointestinal tract causing nonspecific abdominal pain].

The risk of penetration of vena cava filters through the wall of the vena cava is estimated to be as high as 25%, although clinical symptoms are observed far less frequently in patients with this complication. Due to the close relationship between vena cava and duodenum, the latter can be injured by dislocated filters. We describe the presentation, evaluation, and treatment of a patient with a cava filter protruding into the duodenum, and we review the literature.

Complications after endovascular treatment of thoracic aortic aneurysms.

Purpose: To retrospectively determine the value of stent-graft repair of descending thoracic aortic aneurysms by analyzing the results and complications.

Methods: From May 1997 to July 2002, 45 patients (33 men; mean age 69 years, range 31-88) received endovascular treatment for thoracic aortic aneurysms. In 11 patients, emergency treatment was necessary for a contained rupture.

[Monitoring ischemia-/reperfusion syndrome in abdominal aortic aneurysm--conventional operation versus stent implantation].

From a biochemical point of view, our study corroborates the suggestion that implantation of a stent graft is less invasive than conventional surgery for infrarenal aortic aneurysm. In general, ischemia during open aortic surgery lasts shorter but affects a much greater part of the body than stent implantation. Eventration before, and more pronounced reperfusion following conventional repair cause marked intra-operative increases in TxB2, 6-keto-PGF1 alpha, and sICAM-1 levels.
