AbstractBackground:Deformities of the carotid artery are rare. Tortuosity, kinking and coiling of the internal carotid artery may be observed with advancing age. A tortuous internal carotid artery may cause an abnormal sensation in the throat. In the early twentieth century, there were several reported cases of fatal haemorrhage during pharyngeal surgical procedures, because this condition went undetected.Method and results:We present two cases of tortuosity of the right internal carotid artery. Both women complained of abnormal throat sensations. Endoscopic studies and radiological examinations revealed tortuous right internal carotid arteries presenting as pulsatile masses. A literature review revealed that, in most reported cases, this deformity occurred on the right side. We believe that the defect and its right-sided predominance can be attributed to anatomical influences and factors affecting blood pressure.Conclusion:In most reported cases of tortuous internal carotid artery, the defect occurred on the right side and patients complained of an abnormal sensation in the throat. This information is useful in the diagnosis of this condition. It is important for otolaryngologists to recognise this anomaly, because fatal haemorrhage can occur in patients with this condition during surgical procedures on the pharynx.

Abstract The study of CT angiographies performed on a CT scanner GE LightSpeed VCT16 Slice CT revealed some morphological features of the ophthalmic artery related to origin, morphometry and the internal carotid arteries in the vicinity of this artery. The diameter of the left internal carotid artery under the origin of the ophthalmic artery was between 4.0-5.8 mm and that of the right ophthalmic artery at the same level was between 4.1-5.3 mm. Under the origin of the ophthalmic artery, the internal carotid arteries were larger in diameter on the leftside in 80% of cases, with differences of 0.1-0.3 mm, and on the right side these differences were between 0.1-0.2 mm, 20% of cases. The diameter of the left internal carotid artery above the origin of the ophthalmic artery was 3.7-5.0 mm, and the origin of the right carotid artery at the same level was 3.8-5.0 mm.

Carotid artery redundancies are common findings on routine imaging studies and are usually considered to be benign variants. We present a case of a 40-year-old man, with a history of cocaine abuse, who was diagnosed with dissection of the right internal carotid artery and looping of the bilateral internal carotid arteries. This report attempts to highlight the possible association between carotid artery redundancy and dissection, especially in the context of vascular injury such as cocaine abuse, as in our case.

Cerebrovascular stroke caused by skull base meningioma has been rarely reported. A 30-year-old male presented (April 2015) with acute right-sided hemiplegia. His brain neuroimaging (computerized tomography and magnetic resonance imaging) showed left ischemic infarction in the territory of middle cerebral artery. Magnetic resonance imaging also showed a right parasellar solid lesion which extended to the right basisphenoid and cavernous sinus and attenuated the right internal carotid artery. It also had left smaller parasellar extension. The lesion enhanced uniformly and strongly following gadolinium injection. Digital subtraction angiography using selective catheterization of both common carotid and left vertebral arteries (07/13/2015) showed occlusion of both internal carotid arteries and faint visualization of left terminal internal carotid artery and its bifurcation. The right internal carotid artery and its branches were not visualized. Left vertebral injection showed prominent left vertebral and basilar arteries and filling of both internal carotid arteries through posterior communicating arteries. A faint blush of contrast was noticed at the parasellar region coinciding with meningioma. The patient received three treatment sessions of gamma knife radiosurgery as follow: 20 cc of the tumor was treated with 12 Gy (15 August 2015), 1.7 cc was treated with 10 Gy (31 January 2016), and 2.5 cc was treated with 11 Gy (13 August 2016) which resulted in complete clinical recovery and tumor size reduction. Compensation from the posterior communicating and external carotid arteries might explain the complete clinical recovery after tumor size reduction with gamma knife radiosurgery.

AbstractObjective:This study aimed to determine whether magnetic resonance imaging has a role in the evaluation of the sphenoid sinus and internal carotid artery. In addition, we aimed to establish reference measurements for the minimal distance between the internal carotid arteries.Method:The sphenoid sinuses and neighbouring internal carotid arteries of 90 patients were evaluated using sagittal T1-weighted and axial and coronal T2-weighted magnetic resonance images.Results:Sphenoid sinus pneumatisation was categorised as occipitosphenoidal (0 per cent), conchal (3.3 per cent), presellar (14.4 per cent) or sellar (82.2 per cent). The internal carotid artery protruded into the sphenoid sinus in 32.8 per cent, with a septum in 9.4 per cent. The incidence of sellar-type sphenoid sinus pneumatisation was higher in patients with protrusion of the internal carotid artery into the sphenoid sinus (p < 0.001). The incidence of presellar pneumatisation was higher in patients without internal carotid artery protrusion (p < 0.001). The minimal distance between the internal carotid arteries varied between 9.04 and 24.26 mm (mean, 15.94 mm).Conclusion:Magnetic resonance imaging can provide useful information about the sphenoid sinus and internal carotid artery, prior to endoscopic sphenoidotomy and trans-sphenoidal hypophysectomy.

✓ The authors describe their experiences with five patients with delayed transient ischemic symptoms homolateral to internal carotid artery (ICA) occlusions. In each instance, initial arteriograms were interpreted as showing irreversible occlusions of these arteries in the neck and microvascular bypass procedures were contemplated. However, after repeat arteriographic evaluations with a modified injection technique, certain angiographic features were identified that suggested the mechanism of the symptoms in these patients and that their ICA's could be reconstituted in the neck. This was successfully accomplished in each patient with complete relief of ischemic symptoms. The angiographic technique employed and the arterial flow patterns identified in these patients are discussed. The details of the operative technique are described. It is concluded that routine arteriographic techniques may be inadequate to identify the reversible carotid occlusion. This may account for some of the confusion which surrounds the surgery of these vessels as well as the failure of extracranial-intracranial bypass to relieve recurrent ischemic symptoms in these individuals.

Collateral networks between the external carotid artery and internal carotid arteries become crucial for cerebral perfusion after occlusion of internal carotid arteries. We report the first case of a patient who received percutaneous transluminal angioplasty and stenting in a collateral vessel between the external and internal carotid artery for treatment of radiation induced severe stenosis of the internal carotid artery in the context of a contralateral internal carotid artery occlusion.

The risk of stroke and management of coiling of the cervical internal carotid artery in the absence of an atherosclerotic carotid bulb lesion is unclear. We report a case of an otherwise healthy 39-year-old woman who developed bilateral sequential strokes associated with bilateral coiled internal carotid arteries. We discuss the risk of stroke and management of coiled carotid arteries as they relate to the patient presented.

BACKGROUND: Computational fluid dynamics provides a new method for the study of the blood flow characteristics of the formation and development of intracranial aneurysms. OBJECTIVE: To compare blood flow characteristics between the healthy internal carotid artery and normal intracranial aneurysms. METHODS: The internal carotid arteries were simulated to obtain hemodynamic parameters in one patient. RESULTS: The internal carotid artery associated with aneurysm presents low wall shear stress, high oscillatory shear index, and high particle retention time compared with the normal internal carotid artery. CONCLUSIONS: There are differences in blood flow between the normal internal carotid artery and intracranial aneurysm. The vortex of the aneurysm will produce turbulence, indicating that it is unstable, which results in the growth and rupture of the aneurysm.
