Rescue treatment with stenting, balloon angioplasty, and/or intraarterial thrombolysis or antiplatelets are often required to treat the underlying stenosis. 4 Recent literature has reported clinical benefits associated with rescue stenting in the setting of ICAD‐related MT‐refractory strokes.5

Most neurointerventionalists (91%) diagnose ICAS‐LVO after a continued or recurrent occlusion or by the presence of fixed focal stenosis after multiple mechanical thrombectomy attempts. Most respondents (86%) preferred acute treatment of ICAS‐LVO with rescue stenting (RS)±angioplasty.

Treatment of ICAS‐LVO with rescue stenting and/or angioplasty has shown promising outcomes, but diagnosing ICAS‐LVO during MT can be challenging [2, 3]. Most neurointerventionalists (91%) diagnose ICAS‐LVO after a continued or recurrent occlusion or by the presence of fixed focal stenosis (FFS) after multiple MT attempts.

Marked differences can be seen in the prevalence of coronary artery stenosis at autopsy by age and gender. In 30-39 year old women the rate of coronary stenosis at autopsy was 5/1,545 (0.3%) while 60-69 year old men had a prevalence of 12%, almost 40 times higher. The results of this dataset by age and gender follow.
