Agenesis of the internal carotid artery (ICA) is a rare congenital anomaly. Most of the patients are asymptomatic and it is usually discovered incidentally by computed tomography (CT) or magnetic resonance imaging (MRI). There is close association of the cranial aneurysms and subarachnoid hemorrhage with ICA agenesis. We present a case of a 61-year-old male with left ICA agenesis associated with basilar artery and left vertebral artery aneurysms. The patient complained of headaches and numbness on the right-side of the face. Physical examination showed high blood pressure (210/90 mmHg). Neurological examination revealed nystagmus and decreased sensation on the right-side of the face. Agenesis of left ICA, left carotid canal with basilar and left vertebral artery aneurysms were demonstrated incidentally using CT, MRI, and digital subtraction angiography, as a part of an evaluation for suspected cerebrovascular accident.

In this study, the circulus arteriosus cerebri of the squirrel was investigated. Ten squirrel were used. Coloured latex was given from left ventriculi of the all squirrels. Circulus arteriosus cerebri was examined after the dissection was made. The basilar artery was formed by merge of the right and left vertebral artery. The caudal communicans artery which was caudal part of circulus arteriosus cerebri was formed by the basilar artery on sulcus pontocrurale. From caudal to cranial, the branches originated from the basilar artery and circulus arteriosus cerebri to cerebrum and cerebellum were as follows: the caudal cerebelli artery,rami ad pontem, the rostral cerebelli artery, the caudal choroidea artery, the caudal cerebral artery, the internal ophtalmic artery, the rostral choroidea artery, the media cerebral artery, rami striati and the rostral cerebral artery. In squirrels a variability was observed in the branches that the rostral cerebral artery gives, and their endings. It was determined that the internal carotid artery didn’t exist in 4 animals when the right and left vertebral artery were ligatured. It was found that the internal carotid artery didn’t contribute to the arterial blood to circulus arteriosus cerebri and the arterial blood to circulus arteriosus cerebri of squirrels is provided via only the basilar artery.

Von Recklinghausen’S Neurofibromatosis

Abstract A 28-year-old woman with von Recklinghausen's neurofibromatosis (NF-1) had a huge hematoma in the left posterior nuchal region. Carotid and vertebral angiograms revealed marked stenosis at the C3 portion of the left internal carotid artery, slight moyamoya staining, occlusion of the left vertebral artery at the atlas level, and a right internal carotid artery aneurysm. The radiographic, clinical, and histological features of this case are discussed together with a review of 42 similar cases found in the literature. (Neurosurgery 22:544-549, 1988)

The observation of endovascular treatment of acute tandem occlusion of internal carotid artery (ICA), anterior cerebral artery (ACA) and middle cerebral artery (MCA) in combination with the thrombosis of the right ICA and the critical stenosis of the left vertebral artery is presented.Man, 61 years old. He was delivered to the Center of endovascular neuroradiology, NAMS of Ukraine on January 15, 2021 with an ischemic stroke clinic in the left internal carotid artery basin. He fell ill acutely ‒ against the background of complete well-being, sensorimotor aphasia and right-sided hemiplegia appeared. Upon admission on the NIHSS (National Institutes of Health Stroke Scale) ‒ 18 points. On the performed initial multispiral computed tomography of the brain according to ASPECTS (Alberta Stroke Program Early CT score) ‒ 8 points. In the endovascular operating room, cerebral angiography was performed, followed by surgery aimed at restoring cerebral blood flow. The time from the onset of the disease to the puncture was 330 minutes, the duration of the operation was 135 minutes, thus the time from the onset of the disease to reperfusion was 465 minutes. Angiography revealed acute thrombosis of the left ICA starting from the orifice, M1-segment of the left MCA and A2-segment of the left ACA. Partial compensation of the basin through the supra-block anastomosis (external carotid artery ‒ ICA), as well as from the vertebro-basilar system through the network of leptomeningeal arteries. Collaterals ‒ ACG 3. Thrombosis of the right ICA and critical stenosis (95 %) of the V1-segment of the left vertebral artery were also revealed. The operation was performed ‒ recanalization of thrombosis of the left ICA orifice followed by balloon angioplasty, thrombectomy from the MCA and ACA pools. The end result is eTICI 2c reperfusion. There were no complications during this operation. The patient was discharged the next day (transferred to the neurological department at the place of residence). Control multispiral computed tomography of the brain showed positive dynamics (ASPECTS ‒ 1 point).

Introduction Moyamoya disease is a rare and progressive condition with poor long-term prognosis. A meticulous evaluation during an extracranial carotid duplex exam, with attention to subtle changes in anatomy and Doppler signals, can alert the sonographer to pathology in the intracranial circulation, which may suggest this diagnosis. Case Report A 45-year-old woman presented to our vascular lab with an episode of slurred speech, right arm weakness, right-sided numbness, and generalized weakness that lasted 15 – 20 min, with total resolution of symptoms. A carotid duplex examination was ordered and demonstrated no evidence of extracranial carotid disease; however, bilaterally the external carotid artery was larger in size than the internal carotid artery, multiple prominent external carotid artery branches were noted, the internal carotid artery and vertebral artery Doppler signals demonstrated low-resistance waveforms with high diastolic flow velocity, and the left vertebral artery was enlarged. Magnetic resonance imaging with angiography demonstrated multiple intracranial abnormalities, and conventional angiography was compatible with Moyamoya disease. A superficial temporal artery-to-middle cerebral artery bypass was performed with an uneventful postoperative course and no recurrence of symptoms. Conclusions Subtle changes in anatomy and Doppler signals observed during an extracranial carotid duplex examination can be important indicators of pathology in a location that is not under direct visualization and interrogation. It is important for the sonographer to note these changes and report them to the physician for further evaluation by more direct methods of testing. This case provides an example of the use of such indirect sonographic evidence.

Aneurysms of the extracranial portion of the internal carotid artery are rare. Generally, they occur just at the level of, or above, the bifurcation. Here we report a case of a left internal carotid artery aneurysm presenting as an oropharyngeal mass causing dysphagia.

A 42-year-old female patient, who had been diagnosed with an occlusion of her left internal carotid artery (ICA) following Doppler ultrasonographic (US) and digitally-subtracted angiographic (DSA) examinations performed in an outer healthcare center in order to eliminate the underlying cause of her complaint of amorosis fugax, later applied to our hospital with the same complaint. At Doppler US performed in our hospital’s radiology department, her right common carotid artery (CCA) was normal, but her left CCA was hypoplastic. The right internal artery (ICA) was validated as normal. At the left side, however, the ICA was apparent only as a stump and it did not demonstrate a continuity. The diagnosis of ICA agenesis was confirmed by the utilization of Doppler US, CT, and DSA imaging, and it was concluded also that ipsilateral CCA hypoplasia could be evaluated as an important clue to the diagnosis of ICA agenesis.
