Direct Videoscopic Approach to the Descending Thoracic Aorta for Aortic Arch Endograft Delivery: Evaluation in a Porcine Model

Abstract

A direct videoscopic approach to the descending thoracic aorta proved a feasible technique for endograft delivery to the aortic arch in a porcine model.

Assessment of Large Animal Vascular Dimensions for Intra-Aortic Device Research and Development: A Systematic Review

“…Of the 46 selected studies, 30, 15, and 1 reported swine, ovine, and bovine data, respectively. 2 , 10 – 53 In the 1 paper we found describing bovine arterial dimensions, only thoracic aorta measurements were determined to be relevant in this study. We found no study describing aortic arch branch diameters in calves and only 1 study in sheep reporting brachiocephalic trunk diameters.…”

Direct Videoscopic Approach to the Thoracic Aorta for Aortic Endograft Delivery: Evaluation in a Human Cadaver Circulation Model

“…Recently, our group developed a videoscopic approach for direct puncture of the descending thoracic aorta for endograft delivery to the aortic arch. 3 Tested in a porcine model, the descending thoracic aorta proved easily accessible after deflation of the left lung, without the need for dissection or retraction. The use of a double-felted purse-string suture provided adequate hemostasis after catheter removal without the need for aortic cross clamping, while blood loss was kept to a minimum (mean 143 mL).…”

“…We recently described a direct videoscopic approach to the descending thoracic aorta for endograft delivery to the aortic arch in a porcine model. 3 Due to improved maneuverability and fewer restrictions on introducer sheath size, the See commentary page 19 direct videoscopic approach may facilitate branch vessel cannulation and branch graft delivery, especially in those cases where branch vessels arise from the aorta in a difficult angle. The purpose of this study was to assess the feasibility of a direct videoscopic approach to the descending thoracic aorta for branched endograft delivery to the aortic arch and the pararenal aorta in a human cadaver circulation model.…”
