Controlled hypotension is sometimes necessary for accurate endograft deployment and adjunctive ballooning and stenting near the arch and proximal descending thoracic aorta. This article describes a technique in which a compliant occlusion balloon inflated in the right atrium is used to occlude the inflow from the inferior vena cava and reduce the cardiac preload. This reliably and effectively induces systemic hypotension to any desired level and is also able to be rapidly reversed. The technique has been used in 11 cases of thoracic endovascular aortic repairs with complete success and no procedure-related complications.
对于准确植入腔内移植物以及在主动脉弓和胸降主动脉近端进行辅助球囊扩张和支架置入，有时需要控制性低血压。本文介绍了一种技术，即在右心房内充盈顺应性阻塞球囊以阻断下腔静脉的血流并降低心脏前负荷。这能可靠且有效地将全身血压降至任何所需水平，并且还能够迅速逆转。该技术已应用于11例胸主动脉腔内修复术，均取得圆满成功，且无任何与手术相关的并发症。
