A proposed technique for systemic pressure reduction during deployment of a stent graft was studied. A 67-year-old man, who had a descending thoracic aneurysm, was successfully treated with an endovascular procedure. An occluding balloon was introduced into the inferior vena cava (IVC) through the femoral vein. The balloon volume was manipulated with carbon dioxide gas to reduce the venous return, resulting in a transient and well-controlled hypotension. This IVC-occluding technique for systemic pressure reduction may be safe and convenient to minimize distal migration of stent grafts.
研究了一种在植入覆膜支架期间降低全身压力的建议技术。一名患有胸降主动脉瘤的67岁男性通过血管内手术成功治疗。通过股静脉将闭塞球囊引入下腔静脉（IVC）。用二氧化碳气体控制球囊体积以减少静脉回流，从而导致短暂且可控的低血压。这种用于降低全身压力的IVC闭塞技术可能安全且方便，可最大程度减少覆膜支架的远端移位。
