Computed tomography (CT) being performed with Valsalva is an efficacious and common technique performed to evaluate for abdominal hernias. In certain circumstances, Valsalva can generate sufficient intra-abdominal pressure to cause aortoiliac compression that can raise concerns for possible aortic atresia. Repeat CT without Valsalva generally demonstrates that these changes are transitory, and no further intervention is typically required. Given the ever-growing number of CTs with Valsalva being performed for hernia evaluation, clinicians involved in interpreting abdominal CTs should be aware of this concerning appearing but ultimately benign phenomenon.
在进行瓦尔萨尔瓦动作时进行计算机断层扫描（CT）是一种用于评估腹部疝的有效且常用的技术。在某些情况下，瓦尔萨尔瓦动作可产生足够的腹内压，导致腹主动脉髂动脉受压，这可能引发对可能的主动脉闭锁的担忧。不进行瓦尔萨尔瓦动作的重复CT通常显示这些变化是暂时的，通常无需进一步干预。鉴于用于疝评估的进行瓦尔萨尔瓦动作的CT数量不断增加，参与解读腹部CT的临床医生应了解这种看似令人担忧但最终为良性的现象。
