Thoracic Stent Graft with Distal Fenestration for the Superior Mesenteric Artery for Treatment of Thoracic Aortic Aneurysm

Abstract

An 86-year-old man with a 75-mm TAA that terminated just above the celiac artery was treated with a customized Zenith stent graft that had a distal fenestration for the superior mesenteric artery (SMA). Because angiography demonstrated a type IB endoleak, an additional extension stent graft was deployed, and coil embolization of the aneurysmal sac was performed. Three months later, there was no endoleak and good visceral blood fl ow. Placement of a fenestrated thoracic stent graft with a scallop-like fenestration for the SMA is a promising procedure for the treatment of TAAs with a short distal neck.

Effect of Propofol and Isoflurane Long-Term Anesthesia on Rabbit’s Heart Size as Consideration for Biomaterial Implant Placement

“…Suppression of heart function by anesthesia can affect the heart size [2]. Radiography diagnostic commonly used to observe the condition of the heart, especially in vascular opacity redistribution and heart enlargement [5]. The vertebrae heart size (VHS) method was commonly used in animal research, such as in dogs [6], cats [7], and rabbits [5].…”

“…Radiography diagnostic commonly used to observe the condition of the heart, especially in vascular opacity redistribution and heart enlargement [5]. The vertebrae heart size (VHS) method was commonly used in animal research, such as in dogs [6], cats [7], and rabbits [5]. The vertebrae heart size (VHS) is an excellent approach method to examine the effect of respiratory disorder through heart size changes in dog [6], and different cardiac disorders in cat [7].However, the use of VHS method to observe heart functions in long-term anesthesia has not been done.…”
