Internal Carotid Arteries

Formation of the structure and topography of the coronary arteries during the fetal and early neonatal periods of human ontogenesis is an essential constituent while making perinatal diagnosis and understanding real parameters of the norm and pathology. Objective of the study is to determine organometric parameters of the carotid arteries during the fetal and early neonatal periods of human ontogenesis. The study was conducted on 50 specimens of dead fetuses (from 4 to 10 months) and 9 neonates (5 isolated complexes of organs in particular) by means of adequate anatomical methods: macrodissection, injection of the blood vessels, making topographic-anatomical sections, morphometry, and statistical analysis. During perinatal period external diameters and lengths of the carotid arteries are found to be characterized by two periods of an accelerated development and the period of relatively slow development. For the external diameter of the right common carotid artery and the external diameter of the left internal carotid artery the periods from the 4th to 7th months of the intrauterine development and the period from the 9th month to the neonatal period are the periods of an accelerated development; the periods from the 7th to 9th months of development are the period of relatively slow development. The periods from the 4th to the 7th months of the intrauterine development and the period from the 10th month till neonatal period are the periods of an accelerated development for the external diameter of the left common carotid artery and external diameter of the right internal carotid artery; the period from the 7th to the 10th months of development is the period of relatively slow development. The periods from the 4th to the 7th months of the intrauterine development and from the 8th month of development till the neonatal period are the periods of an accelerated development for the external diameter of the right and left external carotid arteries; the period during 7-8th months is the period of relatively slow development. The length of the cervical part of the right and left carotid arteries is characterized by the two periods of an accelerated development – from the 4th to the 6th month and from the 7th month till the neonatal period; the period of relatively slow development is from the 6th to the 7th month of the intrauterine development.  Comparison of the developmental periods of the carotid arteries with all the possible organometric parameters enables to affirm that practically similar enlargement of the external diameters of the common, external and internal carotid arteries both from the right and left sides is peculiar for the period of relatively slow development. The first period of an accelerated development of the carotid arteries is more specific for the external diameter and length of the left common and left external artery contrary to the second accelerated period of development of the carotid arteries. It is characterized by enlargement of the external diameters of the right common and right external carotid artery. A reliable difference of the mean values of the external diameters of the right and left common, external and internal carotid arteries is peculiar for the 4th, 7th, 10th months of development and for the neonatal period for the common carotid arteries; for the external carotid arteries – the 4th, 7th, 9th months of development and neonatal period; for the internal carotid arteries – for the whole months of development.

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.

One of the rare anomalies of the common carotid artery is the separate origin of the internal and external carotid artery. We present the case of a patient who was admitted to hospital for cerebral angiography to exclude an intracranial aneurysm. The DSA revealed a giant aneurysm of the right internal carotid artery and separate origins of external and internal carotid arteries from the aortic arch. To our best knowledge no similar case has previously been reported.

AbstractThe arterial pattern of the human body is one of the systems that show a large number of variations. Many reports are available regarding variations of common carotid, external and internal carotid arteries and branches of external carotid artery. We describe a very rare case of lateral position of external carotid artery. The external carotid artery was lateral to the internal carotid artery at the bifurcation of the common carotid artery. The clinical importance of this variation is discussed.

The accuracy, and possible clinical application of non-invasive ultra sound imaging of the cervical carotid, artery in patients with cerebrovascular disease has been investigated by comparing a pulsed multi-channel directional Doppler imaging devise (“MAVIS” - GEC Medical) with conventional carotid angiography. Of 23 normal or minimally diseased internal carotid arteries only 4 appeared as stenosed on Doppler angiography, the other 19 were normal; of 14 stenosed arteries only 1 appeared normal on imaging,1 appeared occluded end 12 showed clear images of stenosis; all 6 occluded arteries appeared occluded on ultra sound imaging. It was difficult to obtain satisfactory images of the external carotid arteries in all cases. The additional facility to display a velocity flow profile at preselected points along the arterialimage should increase the usefulness of this technique, particularly when there is only minor atheromatous irregularity or ulceration, and such a device will be briefly disrussed.

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.
