(a) Lateral left internal carotid artery
angiographic image from the initial stroke reveals occlusion of the left middle cerebral artery (arrow).
DSA of the left internal carotid artery
showed that blood in the sylvian vein flowed back to the transverse sinus (Fig.
We report our experience in stenting of the left internal carotid artery
(LICA) in patients with bovine arch, in which right brachiocephalic and left carotid share a common trunk from the aortic arch1.
CT angiogram of the head and neck was done and revealed occlusion of his left internal carotid artery
, poor opacification of the left ophthalmic artery, and the presence of good collateral flow from the left posterior cerebral artery and the anterior communicating artery (Figures 1 and 2).
The C6 and C7 segments of the left internal carotid artery
(ICA) also showed high-grade stenosis (Figure 2(a)).
Investigations were continued with CT angiography of cerebral and cervical arteries that confirmed the lesions previously described by echo-Doppler, showing a 50% left common carotid artery stenosis at its bifurcation, an 85% left internal carotid artery
stenosis (Figure 5), as well as complete occlusion of the right internal carotid artery (Figure 6).
Close inspection of the bone windowed CT images (Figure 2) reveals asymmetric lack of a bony left internal carotid canal consistent with congenital left internal carotid artery
CTA imaging showed 90% stenosis of proximal left internal carotid artery
(ICA) with free floating thrombus (FFT) within the lumen along with adjacent calcified atheromatous plaque.
For (RICA) Right Internal Carotid Artery, (LCCA) Left Common Carotid Artery and (LICA) Left Internal Carotid Artery
, there was a significantly higher thickness among patients with hypertension as compared to the control group with p=0.011, p=0.002, and p=0.039 respectively.
IMT far wall of left internal carotid artery
Fig.1: a and b Digital subtraction angiography (DSA) showing a high-grade stenotic lesion (white arrows) at the cavernous segement of the left internal carotid artery
(ICA) 6-month ago.
In the left internal carotid artery
a kink with a 70-degree bend was observed.
