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.
Of note, patient had a with left cavernous‐ICA stent placement a month before the presentation and was noncompliant to antiplatelets. We described a left intracranial ICA flow diversion occlusion without anterior circulation ischemia and left PCA ischemia demonstrated. In the emergency department (ED), her NIHSS was 28.
In his four months follow up clinic visit he had no further concerns of recurrent strokes or new symptoms.ResultsCarotid stump syndrome is a rare cause of cerebral and retinal ischemia; however, it must be considered in patients with recurrent ischemic strokes and chronic ipsilateral ICA occlusion.
Normal RBBB, no evidence of ischemia. It was opened and stented. LV aneurysm puts them at risk for a mural thrombus, which puts them at risk for embolism, especially embolic stroke. In figure 3, I have inverted the image vertically to simulate recording leads from the opposite polarity (see Figure 3 ).
However, by the time of the angiogram it had embolized distally, and had only done so after the right sided ECG was recorded. He did, found the true culprit, and went back in to stent it. See P.S. below ) == P.S. : I believe I found another example of ischemia-induced J waves ( See Oct. The proposed mechanism is complex.
It was treated with and dual "kissing balloons" and drug eluting stents. Here is the post stent ECG: There is greater than 50% resolution of ST elevation (all but diagnostic of successful reperfusion) and Terminal T-wave inversion (also highly suggestive of successful reperfusion). TIMI flow is 0. Door to balloon time was 51 minutes.
There is low voltage in the precordium which always makes reading ischemia harder. In ACS, chest pain is the warning sign of ongoing ischemia. Smith : As Willy says, and as we've said many times before, morphine will resolve pain without resolving ischemia. ECG 1 What do you think? To me, this ECG is not diagnostic.
Management The web can create a flow disturbance, potentiating local thrombus formation, which can embolize producing resulting in cerebral ischemia. Current treatment is with anti-thrombotics and/or anticoagulation.Lesser option is to alter the flow disturbance caused by the web (surgery or stent). Reference 1.Rainer
After stent deployment, we often see improvement in the ST-T within seconds or minutes. Third, a slow motion segment showing delayed, brisk filling of the PDA due to dislodgment of a thrombus from contrast injection and distal embolization. Here is the final angiogram following placement of a stent in the ostial RCA.
His initial high sensitivity troponin I returned at 1300 ng/L and given that his cardiac workup was otherwise unremarkable, a CT was obtained to evaluate for pulmonary embolism and aortic aneurysm or dissection but this too was unrevealing. Another EKG was also obtained. ECG at time 82 minutes: What do you think?
