Purpose: To investigate the effect on intrasac pressure of stent-graft deployment within a life-size silicone rubber model of an abdominal aortic aneurysm (AAA) maintained under physiological conditions of pressure and flow. Methods: A commercial bifurcated device with the polyester fabric preclotted with gelatin was deployed in the AAA model. A pump system generated physiological flow. Mean and pulse aortic and intrasac pressures were measured simultaneously using pressure transducers. To simulate a type I endoleak, plastic tubing was placed between the aortic wall and the stent-graft at the proximal anchoring site. Type II endoleak was simulated by means of side branches with set inflow and outflow pressures and perfusion rates. Type IV endoleak was replicated by removal of gelatin from the graft fabric. Results: With no endoleak, the coated graft reduced the mean and pulse sac pressures to negligible values. When a type I endoleak was present, mean sac pressure reached a value similar to mean aortic pressure. When net flow through the sac due to a type II endoleak was present, mean sac pressure was a function of the inlet pressure, while pulse pressure in the sac was dependent on both inlet and outlet pressures. As perfusion rates increased, both mean and pulse sac pressures decreased. When there was no outflow, mean sac pressure was similar to mean aortic pressure. In the presence of both type I and type II endoleaks, mean sac pressure reached mean aortic pressure when the net perfusion rate was low. Conclusions: In vitro studies are useful in gaining an understanding of the impact of different types of endoleaks, in isolation and in combination, on intrasac pressure after aortic stent-graft deployment.

Introduction. One of the most common complications of endovascular repair of abdominal aortic aneurysm is type II endoleak - retrograde branch flow. Case report. A 76-year-old man with abdominal aortic aneurysm, 7. 1cm in diameter and aneurysm of the right common iliac artery, 3. 2cm in diameter was admitted to our Department with abdominal pain. The patient had no chance of having open repair of abdominal aortic aneurysm because of high perioperative risk (cardiac ejection fraction of 23%, chronic pulmonary obstructive disease). Multislice computed angiography also revealed a large inferior mesenteric artery, 6mm in diameter with the origin in thrombus of aneurysm. We decided to repair abdominal aortic aneurysm with GORE? EXCLUDER ? stent-graft with crossed right hypogastric, but first we decided to embolize the inferior mesenteric artery. Angiography was performed through the right femoral approach and the good Riolan arcade was found. After that the inferior mesenteric artery was embolized with two coils, 5 mm in diameter, at the origin of artery in aneurysm thrombus. At the end of procedure, abdominal aortic aneurysm was repaired with GORE? stent-graft, and the control angiography was performed. There was no endoleak, and the Riolan arcade was very good. The patient was discharged after 5 days. There were no signs of ischemia of the left colon, and peristaltic was excellent. Control multislice computed angiography was done after 1 and 3 months. There were no signs of endoleak. On the control colonoscopy there were no signs of ischemia of the colon. Conclusion. Endovascular repair of symptomatic abdominal aortic aneurysm in high risk patients with preoperative embolization of large branch is the best choice to prevent rupture of abdominal aortic aneurysm and to prevent type II endoleak.
