Mechanical thrombectomy (MT) is an effective treatment in patients with acute ischemic stroke (AIS) due to emergent large-vessel occlusion in the anterior circulation. Occlusion of the anterior cerebral artery (ACA) affects up to 15% of these patients. Here we report a case of an elderly patient with an successful MT of an embolic A2-segment occlussion with the anatomic variation of a triplication. Triplication of ACA is a rare anatomical variation, and the occlusion could have been easily overlooked in case of not performing the CT-perfusion (CTP) sequences. As anatomical variations of the circle of Willis are present in most subjects, CTA alone might be limited in the acute setting, particularly for young residents performing the first view on call. This case highlights the importance of including CTP in the initial CT-diagnostic algorithm in AIS patients who are basically eligible for recanalization therapies, irrespective of inconspicuous initial findings in CTA.

Background/Aims:
Clinical rates of fecal incontinence (FI) are known to vary based on race and ethnicity. It is unclear if anorectal manometry (ARM) findings in patients with FI differ based on ethnicity.
Methods:
High-resolution ARM studies performed between 2014-2021 due to FI at 2 hospitals with multiethnic populations were retrospectively reviewed.
Results:
Four hundred and seventy-nine subjects were included––87 (18.2%) Arab Israelis, 76 (15.9%) immigrants from the former Soviet Union, and 316 (66.0%) Jewish Israelis. Median age was 67 years old (76.0% women: 90.4% were parous). The Arab Israeli group had higher rates of smoking, diabetes, and obesity. Over 95% of ARM’s were abnormal per the London classification including 23% with “combined anal hypotension and hypocontractility,” 36% with “anal normotension with anal hypocontractility,” 67% with “dyssynergia,” and 65% with either “rectal hyposensation” or “borderline rectal hyposensation.” On univariate analyses, significant differences between the ethnic groups were noted in the rates of “anal hypotension with normal contractility,” “combined anal hypotension with anal hypocontractility,” and “dyssynergia.” In multivariate logistic regression analyses controlling for age, gender, parity, smoking, diabetes, and obesity, the Arab Israeli group remained several times more likely to have “combined anal hypotension and hypocontractibility” compared to the other groups.
Conclusions
Ethnicity impacts ARM findings in patients with FI. The reason for this is unclear and future studies on ethnically diverse populations evaluating the clinical relevance of these findings are warranted.
