[Ab] Abstract:OBJECTIVE: To investigate the effect of carotid-carotid artery crossover bypass with a synthetic vascular graft for symptomatic type 1A common carotid artery occlusion (CCAO). METHODS: A retrospective analysis was conducted of patients with symptomatic type 1A CCAO who underwent carotid-carotid artery crossover bypass surgery via a retropharyngeal route with a synthetic vascular graft in the Department of Neurosurgery at our hospital. Preoperative demographic data, surgical complications, incidence of stroke during follow-up, and other clinical data were summarized. RESULTS: Between 2011 and 2016, carotid-carotid artery crossover bypass was performed with a synthetic vascular graft in 4 patients with type 1A CCAO. The mean patient age was 63.3 years (range, 49-69 years). Clinical symptoms included dizziness, amaurosis fugax, persistent limb numbness, and transient ischemic attack. In all 4 patients, postoperative computed tomography angiography showed internal carotid artery thickening due to successful bypass, whereas computed tomography perfusion showed improved postoperative cerebral perfusion on the side of the lesion. The sole perioperative complication was a complaint of foreign body sensation on swallowing in 1 patient. The mean duration of follow-up was 40.3 months (range, 14-77 months), during which no newly occurred cerebral ischemia or synthetic vascular graft occlusion was observed. CONCLUSIONS: Carotid-carotid artery crossover bypass with a synthetic vascular graft is a safe and effective therapeutic approach for patients with symptomatic type 1A CCAO. However, studies with larger series are needed to enable more precise conclusions.

[Ab] Abstract:The internal carotid artery agenesis is a rare malformation disorder. We report the case of a 12-year-old boy suffering migraine, who had presented an episode featuring amaurosis fugax, spontaneously regressed. CT angiography images show hypoplasia of the left common carotid artery with loss of opacification of the left internal carotid artery consistent to agenesis. Moreover CT scans through the skull base demonstrate absence of left petrous carotid canal and an hypertrophic left middle cerebral artery originating from an aberrant artery arising from the right cavernous carotid. All diagnostic examinations confirmed the presence of the internal carotid artery agenesis, as Lie's type IV. We started an annual follow up that over the next 7 years did not reveal any change in magnetic resonance angiography images.

[Ab] Abstract:Carotid artery stenting (CAS) is increasingly utilized in patients with carotid artery stenosis. Various intraprocedural and postprocedural complications have been reported in the literature. We present a case of symptomatic major thromboembolism after CAS. The intraprocedural angiogram showed extraordinary slow filling of the contrast medium into the plaque, which we named as "crevice sign." An 83-year-old man presented repeat right amaurosis fugax for 6 months. The radiological examinations revealed 85% stenosis of the origin of the right internal carotid artery. The patient underwent right CAS. The procedure was performed without any problems; however, the angiogram showed slow filling of contrast medium into the carotid plaque through the stent (crevice sign). Sixty minutes later in the ward, the patient presented sudden onset of left hemiparesis and aphasia. Emergency catheter angiography did not show in-stent thrombus, major artery occlusion, or the crevice sign. Magnetic resonance imaging on the next day revealed wide acute infarction of the right cerebral hemisphere. Physicians should be aware of the intraprocedural crevice sign so that a subsequent catastrophic ischemic event can be prevented.

[Ab] Abstract:A 61-year-old woman visited us with recent onset right-side weakness. Magnetic resonance imaging showed ischemic changes at the left internal border zone due to occlusive disease affecting the left proximal internal carotid artery. Prompt oral dual antiplatelet therapy and intravenous fluid were administered with subsequent induced hypertension and without reperfusion therapy. Although the hemiparesis was improved, she complained of a new-onset transient left-side monocular visual loss. Fluorescein angiography confirmed delayed perfusion in the left eye. We performed extracranial-intracranial bypass for flow augmentation. After bypass, the amaurosis fugax resolved. Follow-up retinal fluorescein angiography also showed improved retinal perfusion.

[Ab] Abstract:A 56-year-old woman was admitted to our hospital because of amaurosis fugax. The carotid angiogram showed irregularly stenotic lesions of the left and right internal carotid arteries (ICAs), suggestive of dissection. Follow-up evaluation was performed by transoral carotid ultrasonography (TOCU) with contrast enhancement (CE), which yielded better vessel lumen and intramural hematoma visualization than color Doppler imaging. CE-TOCU is useful for evaluating ICA dissections that extends to the high cervical portion.

[Ab] Abstract:The value of ICT is important in diagnosis of the diseases of the eye and orbit Methods for direct measurement of intracranial pressure (ICT) are exact, but they are invasive and there is some risk of infection and damage of the tissue. Currently there are 2 valid indirect methods of mesurement of IKT. Digital Ophthalmodynamometry (D-ODM) and Transcranial Doppler ultrasonography (TDU). D-ODM is a non-invasive method for measuring of the Pulsating Venous Pressure (VPT). We can measure VPT by the pulse phenomena. Physiologically (to be maintained blood flow) VPT not be less than the ICT and intraorbital pressure (IorbitT). If we raise the VPT to compensate the current IKT (or IorbitT) - there is a pulsation VCR. We can calculate aproxymative IKT with the formula: IKT = 0.903 - (VPT) - 8.87, or IKT = 0.29 + 0.74 (VOT / PI (AO)). [VOT = intraocular pressure. PI - pulsatility index arteriae ophthalmic from Color Doppler ultrasonography.] IKT can be approximate calculate with mathematical formulas: IKT = 0:55 × BMI (kg / m2) + 0.16 × KTD (mmHg) - 0:18 x age (years) - 1.91. [KTD - diastolic blood pressure, BMI - Body master index] or: IKT = 16.95 x 0.39 x OSASW09 + BMI + 0.14 + TKS - 20.90. [OSASW095: width of the orbital arachnoid space at a distance of 9 mm behind the eyeball (nuclear magnetic resonance). BMI: Body Mass Index. TKS: mean arterial pressure]. Normal values of VPT are under 15 torr. The risk of increased intracranial pressure is above 20 torr. Under physiological conditions, there is intraocular pressure lower in about 5 torr than VPT. CONCLUSION: D-ODM is a useful screening method in the evaluation of IKT for hydrocephalus, brain tumors, cerebral hemorrhage after brain trauma and also in ocular diseases: Glaucoma, Ocular hypertension, orbitopathy (endocrine orbitopathy), ischemic / non-ischemic occlusion of blood vessels of the eye, indirect detection ICT carotid artery-cavernous fistula, amaurosis fugax, optic neuropathy. D-ODM is suitable for immediate evaluation of IKT, but is not suitable for continuous monitoring. As it can be repeated, it is useful for a patient suspected of having an increased ICT.Key words: central retinal artery, central retinal vein, colour Doppler ultrasonography, digital ophthalmodynamometry, intracranial pressure, pressure of cerebrospinal fluid, transcranial Doppler ultrasonography, intraocular pressure, venous pulsation pressure, venous outflow pressure, retinal venous pressure.

[Ab] Abstract:Nowadays, several technically validated modalities are available for imaging both the extracranial and intracranial segments of arteries supplying blood to the brain. In the acute stroke setting, computed tomography (CT) angiography is of utmost importance because it provides the key diagnostic criteria indicative for the use of catheter-based recanalization techniques. Ultrasound imaging of extracranial arteries is most suitable for detecting an underlying stenosis of the internal carotid artery (ICA) in patients with stroke, transient ischemic attacks (TIA), retinal vessel occlusion and amaurosis fugax. Ultrasound imaging enables measurement of the methodologically most reliable criteria for grading stenosis of the ICA, which defines the indications for revascularization procedures in this territory. Magnetic resonance imaging (MRI) in the cross-sectional mode is of greatest value in confirming or excluding an arterial dissection even in short arterial segments, whereas MR angiography generates a more global view of the cerebral circulation. In most cases classical digital subtraction angiography (DSA) is no longer needed for diagnostic purposes only. Conversely, it is an indispensable component of any interventional approach and thus of growing importance. Ultrasound imaging is not indicated for the clarification of vertigo or syncope. In addition, there is no evidence that ultrasound screening of the ICA adds any value to the care of asymptomatic persons.

[Ab] Abstract:Carotid endarterectomy (CEA) reduces the risk of stroke in patients with internal carotid artery stenosis, although the optimal surgical technique is debated. The literature suggests that patch angioplasty reduces complication risk, although primary closure shortens cross-clamp time and eliminates complications associated with grafts. The objective of this study was to assess the complication rate after CEA with primary closure. Retrospective review of 240 consecutive patients between 2002 and 2010. Of these patients, 70% returned for follow-up visits for at least 2 or more years. Primary closure was used in all patients. The average cross-clamp time was 18 minutes. Complications in the immediate postoperative period within 30 days were as follows: stroke ( = 3; 1.1%), transient ischemic attack (TIA; = 4; 1.5%), myocardial infarction (MI; = 3; 1.1%), and death ( = 1; 0.4%). Short-term follow-up revealed eight patients who were found to have significant restenosis (>80%) by carotid duplex imaging. Two to ten year postoperative complication rates were as follows: stroke ( = 7; 4.2%), TIA ( = 7; 4.2%), amaurosis fugax ( = 1; 0.6%), MI ( = 8; 4.8%), and death ( = 28; 17%). Mortality was due to stroke or heart attack ( = 2; 1.2%), cancer ( = 7; 4.2%), and unknown causes ( = 19; 11%). This study presents our experience with complications after primary closure after CEA. In our experience, CEA is a safe and effective surgical means of preventing stroke in the short term. Well-designed prospective studies are needed to confirm specific patient characteristics in which primary closure and patch angioplasty are indicated.

[Ab] Abstract:OBJECTIVE: To compare prevalence of carotid artery disease and its various types of lesions in different types of ocular arterial occlusive disorders. DESIGN: Cohort study. SUBJECTS: 614 consecutive patients (728 eyes) with ocular arterial occlusive disorders. METHODS: At first visit, all patients had a detailed ophthalmic and medical history, comprehensive ophthalmic evaluation, and carotid artery evaluation (by Doppler/angiography) on the side of ocular arterial occlusion, and echocardiography. The same ophthalmic evaluation was performed at each follow-up visit. Ocular arterial occlusive disorders were divided into central (CRAO) and branch (BRAO) retinal artery occlusion, ocular ischemic syndrome (OIS), non-arteritic anterior ischemic optic neuropathy (NA-AION) and amaurosis fugax (AF). MAIN OUTCOME MEASURES: Carotid artery and echocardiographic abnormalities, and incidence of transient ischemic attack (TIA)/stroke and myocardial ischemia. RESULTS: The study consists of a cohort of 266 eyes with NA-AION, 203 with CRAO, 127 with BRAO, 80 with OIS and 52 with AF. Carotid artery stenosis on the involved side was worse in AF and OIS compared to BRAO, CRAO, and NA-AION (p<0.0001). Presence of carotid artery plaques on the involved side was significantly higher in OIS, AF, and CRAO compared to NA-AION (p=0.002, p=0.003, and p=0.0003, respectively). Echocardiography revealed an embolic source in 61% of CRAO and 53% of BRAO compared to only 3% of NA-AION patients (p<0.0001). TIA/stroke before or after onset of ocular condition occurred in 17% of OIS, 11% of AF, 7% of CRAO, 6% of NA-AION, and 3% of BRAO patients. Kaplan-Meier estimate of the incidence of TIA /stroke within 3 months after onset was 6% (95% CI: 2%, 17%) for OIS, 3% (95% CI: 0.4%, 19%) for AF, and 1% (95% CI: 0.3%, 4.1%) for CRAO. Report of myocardial ischemia before or after onset of ocular condition was 52% in AF, 22% in OIS, 22% in BRAO, 21% in CRAO, and 6% in NA-AION patients. CONCLUSIONS: The incidence of carotid artery stenosis and plaques, cardiac embolic source, TIA/stroke and myocardial ischemia differ among various ocular arterial occlusive disorders. The role of embolism and hemodynamic disturbances caused by carotid artery disease in these disorders is discussed.
