Thrombosis of the internal carotid artery due to soft palate injury

AbstractThrombosis of the internal carotid artery is a rare complication of soft palate injury, only 16 cases having been previously documented. We present the case of a 51/2 year-old-boy who sustained an apparently trival laceration to the right aspect of the soft palate. However, 48 hours after injury, a right cerebral infarct occurred with subsequent left hemiparesis. On supportive and rehabilitative management he made a good recovery over a period of one year.

Introduction. An extracranial carotid artery aneurysm is a rare clinical entity with potentially debilitating consequences. Our aim is to present a case of a large internal carotid artery aneurysm combined with medial internal carotid artery (ICA) kinking successfully treated by resection with an end-to-end anastomosis. Case outline. A 34-year-old female patient was admitted to our hospital due to dizziness and frequent non-specific headaches. On admission, routine echocardiography showed an aneurysm of the atrial septum. Multislice computed tomography of the supraaortic branches showed medial kinking of the right ICA with a 15 mm aneurysm localized on the vertex of the angulation. Kinking was present on the left ICA as well, with a small aneurysm of 5 mm in diameter. The right ICA aneurysm was resected and the artery was reconstructed with an end-to-end anastomosis. The postoperative course was uneventful and the patient was symptom-free after a one-year follow-up. Conclusion. We showed that surgery of an aneurysm and kinking of the carotid artery in the medial segment of the ICA is possible and safe to perform. Detailed preoperative preparation, precise surgical technique, and short clamping time all contributed to a good final outcome.

Head And Neck Injury

Abstract Intracranial occlusion of the internal carotid artery secondary to minor head or neck injury is uncommon. We report the case of an 18-year-old man who sustained a minor head and neck injury during a fist fight and developed a left hemiparesis resulting from thrombosis of the supraclinoid portion of the right internal carotid artery. Conservative inpatient treatment with low dose heparin and aspirin resulted in a gradual, steady improvement. Two months later, after an intensive program of physical therapy, the patient showed good progress; his facial weakness had lessened and his left hemiparesis was mild. Although there is no ideal treatment for internal carotid artery occlusion secondary to minor trauma, conservative treatment should be undertaken unless there are progressive or recurring ischemic symptoms, in which case an extracranial-intracranial bypass operation should be considered.

Internal carotid artery pseudoaneurysm is a rare complication of deep neck infections. The authors report the case of a 17-year-old male who presented to the Department of Otorhinolaryngology with an acute tonsillitis requiring tonsillectomy. Four weeks after the surgery the patient was readmitted because of progressive swallowing, trismus, and worsening headache. Computed tomography revealed a pseudoaneurysm of the left internal carotid artery in the extracranial segment. A bare Wallstent was implanted primarily and a complete occlusion of the pseudoaneurysm was achieved. The endovascular approach is a quick and safe method for the treatment of a pseudoaneurysm of the internal carotid artery.

Supraclinoid Internal Carotid Artery

AbstractAnterior clinoidal meningiomas (ACMs) remain a major neurosurgical challenge. The skull base techniques, including extradural clinoidectomy and optic unroofing performed at the early stage of surgery, provide advantages for improving the extent of resection, and thereby enhancing overall outcome, and particularly visual function. Additionally, when the anterior clinoidal meningiomas encase neurovascular structures, particularly the supraclinoid internal carotid artery and its branches, this further increases morbidity and decreases the extent of resection. Although it might be possible to remove the tumor from the artery wall despite complete encasement or narrowing, the decision of whether the tumor can be safely separated from the arterial wall ultimately must be made intraoperatively.The patient is a 75-year-old woman with right-sided progressive vision loss. In the neurological examination, she only had light perception in the right eye without any visual acuity or peripheral loss in the left eye. MRI showed a homogeneously enhancing right-sided anterior clinoidal mass with encasing and narrowing of the supraclinoid internal carotid artery (ICA). Computed tomography (CT) angiography showed a mild narrowing of the right supraclinoid ICA with associated a 360-degree encasement. The decision was made to proceed using a pterional approach with extradural anterior clinoidectomy and optic unroofing. The surgery and postoperative course were uneventful. MRI confirmed gross total resection (Figs. 1 and 2). The histopathology was a meningothelial meningioma, World Health Organization (WHO) grade I. The patient continues to do well without any recurrence and has shown improved vision at 15-month follow-up.This video demonstrates important steps of the microsurgical skull base techniques for resection of these challenging tumors.The link to the video can be found at https://youtu.be/vt3o1c2o8Z0

Abstract Background In recent years, the incidence of stroke has gradually increased in young people. There are many reasons causing stroke, including atherosclerosis, artery embolization, and cervical artery dissection and so on. However, cervical artery dissection is a major cause of stroke in young people. We present a case of ischemic stroke caused by dissection, whose distal vascular occlusion due to detachment of the thrombosis in the right internal carotid artery. Case presentation A 33-year-old male patient was admitted to the hospital because of stroke. Imaging examination showed that there was no visualization of the right middle cerebral artery and there were a large number of mural thrombus in the C1 segment of the right internal carotid artery. After emergency surgery, the patient had vascular recanalization and the symptoms were significantly improved. Magnetic resonance imaging showed a high signal in the C1 segment of the right internal carotid artery, the abnormal signal disappeared after antiplatelet therapy. Conclusions When a patient has symptoms of stroke, we need to explore the root cause of stroke. Especially in young people, cervical artery dissection is an important reason that can’t be ignored. Through review and analysis of this case, we hope to improve the understanding of radiologists and clinicians about the cervical artery dissection, reduce the rate of misdiagnosis, and improve patients’ prognosis.

Abstract A 54-year-old man with a right hemiparesis was found to have an intrasellar intercarotid communicating artery associated with agenesis of the right internal carotid artery. Magnetic resonance imaging (MRI) studies demonstrated the spatial relationship of the anomalous artery to the surrounding structures, thus suggesting an embryonic enlargement of the capsular artery as a source of this anomalous artery.

The authors demonstrate the use of an endovascular plug in securing a carotid artery pseudoaneurysm in an emergent setting requiring craniotomy for a concurrent subdural empyema.They describe the case of a 14-year-old boy with sinusitis and bifrontal subdural empyema who underwent transsphenoidal exploration at an outside hospital. An injury to the right cavernous segment of the ICA caused torrential epistaxis. Bleeding was successfully controlled by inflating a Foley balloon catheter within the sphenoid sinus, and the patient was transferred to the authors’ institution. Emergent angiography showed a dissection of the right cavernous carotid artery, with a large pseudoaneurysm projecting into the sphenoid sinus at the site of arterial injury. The right internal carotid artery was obliterated using pushable coils distally and an endovascular plug proximally. The endovascular plug enabled the authors to successfully exclude the pseudoaneurysm from the circulation. The patient subsequently underwent an emergent bifrontal craniotomy for evacuation of a left frontotemporal subdural empyema and exenteration of both frontal sinuses. He made a complete neurological recovery.Endovascular large-vessel sacrifice, obviating the need for numerous coils and antiplatelet therapy, has a role in the setting of selected acute neurosurgical emergencies necessitating craniotomy. The endovascular plug is a useful adjunct in such circumstances as the device can be deployed rapidly, safely, and effectively.

Cervical Internal Carotid Artery

Background: Cervical internal carotid artery (ICA) tortuosity has been associated with vascular risk and stroke as well as genetic disorders related to abnormal extracellular matrix remodeling. It is plausible that dystrophic or aberrant arterial remodeling may therefore relate to cervical ICA tortuosity. We hypothesized that cervical ICA tortuosity relates to carotid dilatation, but not to traditional ultrasound (US) markers of atherosclerosis. Methods: Subjects of the NOMAS with available time-of-flight MRA were included in our study. Cervical ICA tortuosity was defined as a bend in the distal cervical ICA of > 90° as seen on MRA. We excluded subjects with < 5 cm of the cervical ICA visualized. Distensibility was calculated as the percentage excursion of the right CCA diastolic diameter during systole, which was assessed by high-resolution B-mode US of the right common carotid artery (CCA). We used multivariable logistic regression analyses to estimate odds ratios for the association of cervical ICA tortuosity and Doppler measures of carotid wall aging. Results: We visualized cervical ICA tortuosity in 468 NOMAS participants (mean age 64±8 years, 70% women, 70% Hispanic). It was present in 23% of subjects. In unadjusted models, cervical ICA tortuosity was more common in women (OR 2.34, 95% CI 1.34-4.11), Hispanics (OR 1.85, 95%CI 1.06-3.25) and those with higher diastolic blood pressures (OR per mm Hg 1.04, 95%CI 1.01-1.06), and less common among smokers (OR 0.23, 95%CI 0.07-0.78). In models adjusted for demographic and vascular risks, right CCA tortuosity was associated with ipsilateral larger CCA DD (OR 1.42, 95%CI 1.02-1.96) and borderline associated with lower distensibility (OR 0.94, 95%CI 0.87-1.01, P=0.06) but not with ipsilateral ICA IMT (OR 0.26, 95%CI 0.14-4.77), number of plaques (OR 1.08, 95%CI 0.76-1.53), maximum plaque thickness (OR 0.96, 95%CI 0.73-1.27), or plaque area (1.00, 95%CI 0.97-1.05). Conclusions: Cervical ICA tortuosity associates with ipsilateral cervical ICA dilatation and lower distensibility, but not with traditional US markers of atherosclerosis. The association with diastolic blood pressure suggests a role of steady, rather than pulsatile, hemodynamics in aberrant cervical ICA remodeling.

Introduction : A 51‐year‐old lady with a past medical history of Essential Hypertension, Hypothyroidism, prior Herpes Zoster infection 8 weeks ago was admitted with complaints of abdominal pain, bilateral flank pain, and restlessness. Her initial workup was significant for hyponatremia and hypokalemia. On the 3rd day of admission, she developed acute hypoxemic respiratory failure which led to intubation. At that time, CTA Chest was not done but CT Chest revealed prominent mucous plugging with left side glass ground opacities, Ultrasound of lower extremities revealed right common femoral vein DVT which led to concerns that she may have suffered from Pulmonary Embolism and led to starting Heparin drip. On the 6th day of admission, she developed Acute Encephalopathy, MRI Brain revealed acute infarcts in bilateral cerebral cortices and cerebella, CT Angiogram Head showed acute subarachnoid hemorrhage in the high posterior right parietal lobe, stenosis of the right high cervical internal carotid artery, and irregular, the appearance of the arterial vasculature throughout and CT Angiogram Neck abrupt change in caliber of the right ICA, 1.5 cm distal to the bifurcation with markedly severe narrowing of the majority of the extracranial right ICA throughout its course. A cerebral Angiogram was done which showed diffuse tandem segments of tandem cervical and intracranial portions of the right internal carotid artery and she was given nitroglycerin was administered as a therapeutic intervention. Lumbar Puncture showed WBC 2, RBC 7, Protein 162, Glucose 64, VZV PCR was negative, CSF VZV IgG Antibody positive at 303 IV (>165 IV indicative of current or past infection). Serum VZV IgG Antibody was positive at >4000 IV. Infectious Diseases were consulted after Lumbar Puncture, they initially started Acyclovir but once the Serum VZV IgG Antibody came back much higher than Serum VZV IgG Antibody levels, their assessment was that VZV vasculitis is unlikely and Acyclovir was discontinued. Eventually, the case was discussed at Neuroradiology which led to us getting a repeat MRA Neck without contrast which showed a concentric T1 and T2 hyperintensity along with a small and irregular caliber right cervical ICA consistent with dissection. She eventually completed a 21‐day course of Nimodipine due to underlying Subarachnoid Hemorrhage. Methods : NA Results : NA Conclusions : Our case demonstrates how it can become difficult to ascertain the etiology of stroke in certain patients. Our patient presented with multiple non‐specific symptoms initially and it was later on due to her Acute Encephalopathy that her Strokes and Subarachnoid Hemorrhage were discovered. It is still difficult to pinpoint whether the cause of strokes was dissection or VZV infection. Lumbar Puncture remains an essential tool to complete work up on uncommon etiologies of stroke.
