Extracorporeal membrane oxygenation is an artificial cardiopulmonary bypass technique used to support patients with severe pulmonary failure or both pulmonary and cardiac failure. The hemodynamic changes produced by extracorporeal membrane oxygenation affect the appearance of CTA of the head images, often confounding interpretation if the correct history and understanding of extracorporeal membrane oxygenation are not known. This technical report describes the principles of extracorporeal membrane oxygenation, techniques to optimize intracranial CTA imaging, and pitfalls.
体外膜肺氧合是一种人工心肺旁路技术，用于支持患有严重肺衰竭或心肺功能衰竭的患者。体外膜肺氧合所产生的血流动力学变化会影响头部CTA图像的表现，如果不了解体外膜肺氧合的正确病史和相关知识，常常会使图像解读产生混淆。本技术报告描述了体外膜肺氧合的原理、优化颅内CTA成像的技术以及相关陷阱。
