Separate origins of the left internal and external carotid arteries from the aortic arch: MR angiographic findings.
نویسندگان
چکیده
Agenesis of the left common carotid artery with independent origins of the internal and external carotid arteries arising directly from the aortic arch is an extremely rare congenital anomaly. We present MR angiographic findings in a case with agenesis of left common carotid artery that, to our knowledge, is unique by virtue of its detection and description with MR angiography.

Common Carotid Artery Agenesis: Duplex Ultrasonographic Findings
BACKGROUND Agenesis of the common carotid artery (CCA) resulting in separation of the origin of the external carotid artery (ECA) and internal carotid artery (ICA) from the aortic arch is rare. Fewer than 25 cases have been reported, and correlative ultrasound data were available for only 1 of them. CASE REPORT A 52-year-old woman visited the hospital with a 3-day history of vertigo and heada...

Background: A correlation between coronary artery disease (CAD) and atherosclerosis of peripheral arteries and the determination of noninvasive indexes for its existence and extent have been sought by many researchers. Some studies report that the intima-media thickness (IMT) of peripheral arteries could play this role. This study evaluated the correlation between the IMTs of common carotid and...
متن کاملMultidetector-row CT angiographic findings in the bilateral aortic arch origin of the vertebral arteries.
We recently read the interesting article by Albayram et al (1), which concisely explained the anomalies of the vertebral arteries. We would like to present another rare case of bilateral vertebral arteries originating from the aortic arch. We incidentally diagnosed this condition on the basis of findings on a chest CT scan obtained in a patient with trauma. Our trauma chest CT protocol uses 8 2...
متن کاملImaging findings in a child with Loeys-Dietz syndrome.
A 3-year-old boy being followed up for bilateral club foot underwent a routine thorax radiography that revealed aortic arch enlargement. Echocardiography showed sinus of Valsalva dilatation. Because of clinical features such as hypertelorism, bifid uvula, and prominent forehead, a genetic investigation was conducted that confirmed Loeys-Dietz syndrome (LDS) by identifying a heterozygous mutatio...
متن کاملIntra-arterial digital subtraction angiography through the ear artery for experimental aneurysm imaging.
Digital subtraction angiography through the central artery of the ear was performed to show elastase-induced aneurysms in 34 rabbits. Twenty-eight (82%) aneurysms in which common origins of the bilateral common carotid artery (CCA) were found were well shown. All 6 other aneurysms not well shown had separate origins of the CCAs from the aortic arch (P < .001). This method can be used for angiog...
