Three-Dimensional Modeling Analysis of Visceral Arteries and Kidneys during Respiration

摘要

BackgroundVisceral arteries are commonly involved in endovascular repair of complex abdominal aortic aneurysms. To improve repair techniques and reduce long-term complications involving visceral arteries, it is crucial to understand in vivo arterial geometry and the deformations due to visceral organ movement with respiration. This study quantifies deformation of the celiac, superior mesenteric, and renal arteries during respiration, and correlates the deformations with diaphragmatic excursion.
