In this phenomenon, a thrombus forms within the lumen of the stent graft component of the frozen elephant trunk prosthesis and puts the patient at risk for downstream embolization with visceral or lower limb ischemia. Therefore, the presence of ILT is associated with increased short-term mortality and morbidity.

PCI is commonly used to open blocked arteries to treat significant myocardial ischemia , which occurs when the heart muscle does not get enough oxygenated blood. During PCI, an operator inserts a stent into a blocked artery through a catheter in the groin or arm.

We already know that the ischemia is ongoing, though mild (because of the persistent pain). The culprit was opened and stented.
