Ascending pharyngeal-vertebral anastomosis has been identified by angiography of the carotid artery in several cases. We present a case of ascending pharyngeal-vertebral anastomosis that was found incidentally in computed tomography angiography of the ascending pharyngeal artery. Images revealed that the anastomosis formed through the hypoglossal branch of the neuromeningeal trunk. The anastomosis seemed to be associated with hypoplasia of the right vertebral artery. Interventional radiologists should be aware of this dangerous anastomotic route of the APA to the VA. Discovery of hypoplasia of the major intracranial arteries before intra-arterial chemotherapy or embolization in head and neck area may avoid subsequent complications.

Double Origin

Vertebral artery origin anomalies are typically incidental findings during angiography. We present an extremely rare variant in which the right vertebral artery has a double origin from the right subclavian artery and right common carotid artery in association with an aberrant right subclavian artery, which has never been reported before.

AbstractA three-year old bot wiht a swelling on the right side of his neck was suspected of having parapharyngeal abscess after clinical examination and CT scan(computed tomography scan) of this region. Later it became clear, that the swelling was caused by an aneurysm of the internal carotid artery. This case report describes the pitfalls and difficulties encountered in the diagnostic course and treatment planning.

Abstract BACKGROUND AND IMPORTANCE: This is the first report of using the superior lateral mass as an alternative starting point for C1 posterior screw placement, demonstrating the importance of recognizing vertebral artery (VA) anomaly in deciding the surgical strategy for C1 screw placement. CLINICAL PRESENTATION: A 56-year-old man presented with severe neck pain after a fall. Imaging demonstrated an unstable bursting fracture at C4, C1-2 instability, and a subluxation at C2-3. Computed tomography angiography indicated that the persistent first intersegmental artery was located on the left side. The patient underwent anterior-posterior cervical fixation and fusion. Posterior C1 fixation was done with polyaxial screw rod construct using C1 superior lateral mass on the left side and C1 inferior lateral mass on the right side. The patient had no immediate postoperative deficits. At the 8-month follow-up examination, the patient was neurologically intact with a solid cervical fusion. CONCLUSION: The third segment of the VA is heterogeneous; therefore, preoperative radiologic studies should be performed to identify any anatomical variations. Using preoperative 3-dimensional computed tomography angiography, we can precisely identify an anomalous VA, thereby significantly reducing the risk of VA injury. To avoid significant morbidities associated with VA injury, a more optimal entry point for C1 fixation can be selected if a persistent first intersegmental artery or fenestrated VA is detected.

Vertebral Arteries

Vertebrobasilar insufficiency leading to posterior circulation infarcts caused by congenital hypoplasia of the bilateral transverse foramina at the C2 level, affecting the caliber and flow of the bilateral distal cervical vertebral arteries in an adult, has not been previously reported. A 41-year-old male presented with episodic dizziness for a period of 1 year prior to consultation. Computed tomography angiography of the head and neck demonstrated congenital hypoplasia of the bilateral C2 transverse foramina, with absence of the vertebral arteries in each of the foramina and collateral reconstitution of diminutive intracranial vertebral artery segments. Brain MRI showed postinfarction encephalomalacia in the bilateral cerebellar hemispheres. The patient was considered not a surgical or endovascular candidate and was managed conservatively with antiplatelet therapy. Congenital anomalies of the bilateral cervical transverse foramina may present with vertebrobasilar insufficiency and infarction in adulthood.

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).
