“…We also used a simple grading system for the calcifications rather than volume assessment. Another study using 4 grade simple scale system on CTA images demonstrated a higher correlation between the calcification scores of the ICA origins and the orifices of large vessels originating from the aortic arch than between the ICA origins and the aortic arch 5 . Adar et al reported aortic arch calcification as a strong and independent predictor of coronary artery calcification 14 .…”

“…However CTA is not a suitable imaging modality for screening because of radiation exposure. Additionally, the classification of vascular calcifications with a simple 4 or 5 grading system is useful only for evaluating short segments of major vessels 5 . Therefore, the relationships that we investigated between aortic arch and relatively short segments of carotid arteries may be beneficial at chest CT in our daily practice.…”

The aim of this study is to evaluate the association of calcifications at aortic arch with different segments of carotid arteries. Material and Methods: Carotid computed tomography (CT) angiography examinations of 134 patients, which were performed between January 2013 and February 2015, were retrospectively evaluated. Calcifications at aortic arch, orifice of brachiocephalic trunk, orifice of common and internal carotid arteries, petrous and cavernous/ophthalmic segments of internal carotid arteries were scored. Results: A statistically significant relationship was detected between calcification scores of aortic arch and brachiocephalic trunk orifice, left common carotid artery orifice, both internal carotid artery orifice, both internal carotid artery cavernous/ophthalmic segments. There was a statistically significant correlation between the age and total calcification scores. However, there was not a relationship between the calcification scores of aortic arch and right common carotid artery orifice, aortic arch and both internal carotid artery petrous segments. Conclusion: Aortic arch calcifications detected at routine chest CT may be useful to predict the calcification scores of internal carotid artery segments and total carotid calcification score. Amaç: Bu çalışmanın amacı arkus aortadaki kalsifikasyonların, karotis arterin farklı segmentlerindeki kalsifikasyonlarla ilişkisini değerlendirmektir. Gereç ve Yöntem: Ocak 2013 Şubat 2015 tarihleri arasında, karotis bilgisayralı tomografi (BT) anjiyografi yapılmış 134 hastanın tetkikleri retrospektif olarak değerlendirildi. Arkus aorta, brakiosefalik trunkus orifisi, her iki ana karotis ve internal karotis arter orifisleri, her iki internal karotis arter petröz ve kavernöz/oftalmik segmentlerindeki kalsifikasyonlar skorlandı. Bulgular: Arkus aortadaki kalsifikasyonlar ile brakiosefalik trunkus orifisi, sol ana karotis arter orifisi, her iki internal karotis arter orifisi ve her iki internal karotis arter kavernöz/oftalmik segmentinde skorlanan kalsifikasyonlar arasında istatistiksel olarak anlamlı ilişki tespit edildi. Yaş ile total kalsifikasyon skoru arasında da istatistiksel olarak anlamlı ilişki saptandı. Ancak arkus aortadaki kalsifikasyonlar ile sağ ana karotis arter orifisi ve her iki internal karotis arter petröz segmentinde skorlanan kalsifikasyonlar arasında istatistiksel olarak anlamlı ilişki saptanmadı. Sonuç: Rutin toraks BT tetkiklerinde arkus aortada izlenen kalsifikasyonlar, karotis arterin farklı segmentlerindeki kalsifikasyonlar ve toplam karotis kalsifikasyon skoru için bir öngörü sağlayabilir.

ICAC suggests a heavier atherosclerosis burden and a higher risk of vessel stenosis, especially medial arterial calcification, which could affect the regulation of blood vessels [10][11][12] . Previous studies have explored the correlation between intracranial internal carotid artery calcification and HT or poor prognosis after thrombolysis, but the conclusions are inconsistent [13][14][15] , and no quantitative study has been conducted.…”

Hemorrhagic transformation is the major complication of intravenous thrombolysis. Calcification is used widely as an imaging indicator of atherosclerotic burden and cerebrovascular function. The relationship between intracranial calcification and hemorrhagic transformation has not been explored fully. We aimed to identify and quantify calcification in the main cerebral vessels to investigate the correlations between quantitative calcification parameters, hemorrhagic transformation, and prognosis. Methods: Acute, non-cardiogenic, ischemic stroke patients with anterior circulation who received intravenous thrombolysis therapy in the First Hospital of Jilin University were retrospectively and consecutively included. All included patients underwent a baseline CT before intravenous thrombolysis and a follow-up CT at 24 hours. A third-party software, ITK-SNAP, was used to segment and measure the calcification volume. A vascular nonbone component with a CT value 130 HU was considered calcified. Hemorrhagic transformation was determined based on the ECASS II classification criteria. Results:The study included 242 patients, 214 of whom were identified as having calcification. Thirty-one patients developed hemorrhagic transformation. The calcification volume on the lesion side (0.1ml) was associated with hemorrhagic transformation (p 0.004, OR 1.504, 95% CI: 1.140-1.985). Ninety-six patients had poor prognoses. The poor prognosis group had more calcified vessels than the good prognosis group (p 0.014, OR 1.477, 95% CI: 1.083-2.015). Conclusions:The arterial calcification volume on the lesion side is associated with hemorrhagic transformation after thrombolysis. The higher the number of calcified vessels, the greater the risk of poor prognosis.for early reperfusion, significantly reducing disability and fatality in acute ischemic stroke patients 1,2) .

Arterial Location-Specific Calcification at the Carotid Artery and Aortic Arch for Chronic Kidney Disease, Diabetes Mellitus, Hypertension, and Dyslipidemia

Several risk factors for arterial calcification have been reported but controversial. The aim of this study was to clarify the interactions among chronic kidney disease (CKD), diabetes mellitus (DM), hypertension, and dyslipidemia in altering the risk of arterial calcification in the three different arterial locations and the intramural location at the internal carotid artery (ICA) origins. Calcified burdens at the ICA origins, the aortic arch, and its orifices were evaluated in a retrospective fashion by using computed tomography angiography in 397 patients. The multivariate analyses were adjusted for age, gender, CKD, DM, hypertension, dyslipidemia, and current smoking status. Additionally, subgroup analyses in each variable were conducted. Our multivariate logistic regression analyses revealed that CKD was significantly associated with the outside-wall calcification at the ICA origins, whereas DM was only associated with the inside-ICA-wall calcification. Additionally, we found that DM increased the association between CKD and arterial calcification at the aortic arch and its orifices, and the outside-wall at the ICA origins. Hypertension was significantly associated with the calcification at the orifices of the aortic arch branches synergistically with CKD. Dyslipidemia did not have any significant association with calcification in any of the three vascular beds. CKD had the highest prevalence risk of calcification in common with the three different vascular beds. CKD in combination with DM, as well as hypertension in combination with CKD, were key relationships affecting the risk of arterial calcification, especially at the aortic arch and its orifices.
