Artery Disease

Carotid artery disease leads to stroke in 30% of cases. The total frequency of carotid artery deformations varies from 10 to 40% depending on the results of angiographic and pathological examinations. Coiling of the internal carotid artery is associated with embryological pathology, and elongation and inflection are the result of fibromuscular dysplasia or changes that are accompanied by atherosclerotic damage to the arteries. Kinking – an artery bend at an acute angle. It can be congenital, when from early childhood there is a violation of cerebral circulation and develops over time from an elongated carotid artery. The formation of inflections contributes to hypertension, the progression of atherosclerosis. Coiling – the formation of a loop of an artery. Despite the smooth running of the loop, the changes in bleeding in it are significant. The nature of bends in coiling can vary depending on body position, blood pressure. The most common is the elongation of the internal carotid or spinal artery, which leads to the formation of smooth curves along the vessel. Elongation of the arteries is usually detected in random studies. The main etiological causes of pathological tortuosity of the internal carotid artery include: congenital deformation of the vascular wall, hypertension, osteochondrosis of the cervical vertebrae, compression of the bracheocephalic arteries, cranial nerves. The review article deals with anatomy and topography of the major vascular-nervous bundle components of the neck on the stages of early ontogenesis from the point of view of surgical correction of departures from their normal development in newborns and children of an early age. However, literary data are controversial and fragmentary concerning anatomical peculiarities of the carotid arteries, internal jugular vein, and vagus. The facts concerning synoptic correlation of the major vascular-nervous bundle components of the neck in fetuses and newborns are not systematized. Carotid artery disease leads to stroke in 30% of cases. The total frequency of carotid artery deformations varies from 10 to 40% depending on the results of angiographic and pathological examinations.

Abstract Carotid endarterectomy is a commonly performed operation to prevent stroke in patients who have asymptomatic or symptomatic internal carotid artery atherosclerotic stenosis. Carotid angioplasty and stenting has also been advocated for treatment of these patients. In this article, we address a number of questions for which a review of available data will advance our understanding of the role of carotid endarterectomy in stroke prevention. These include the following: Are carotid endarterectomy and carotid angioplasty and stenting equivalent procedures for the treatment of carotid artery disease? Which patients should be deemed at high risk for carotid endarterectomy? Should carotid endarterectomy be an urgent procedure in symptomatic patients with severe internal carotid artery stenosis? Finally, what is the role of carotid endarterectomy in asymptomatic patients? We also review the senior author's personal experience with >2000 consecutive carotid endarterectomies, with special attention to his present approach to this operation. We believe that carotid endarterectomy, in experienced hands, is a minimally invasive operation that remains the procedure of choice for most patients with carotid artery disease who will benefit from invasive treatment.

Introduction: Novel multi-parametric criteria for duplex ultrasonography (DUS) grading of extracranial internal carotid artery (ICA) steno-occlusive disease have been recently introduced by the German ultrasound expert panel (DEGUM). We sought to determine diagnostic accuracy of the DEGUM criteria against the gold standard catheter angiography. Methods: We prospectively enrolled consecutive patients who routinely underwent diagnostic or therapeutic catheter angiography of the extracranial carotid arteries in four German study sites. Internal carotid artery disease was graded according to the DEGUM multi-parametric criteria for DUS. On angiography, extracranial ICA disease was graded using the NASCET approach. Ultrasonography and endovascular raters were blinded to clinical data and any other imaging modalities. To correspond to clinically relevant NASCET groups, all stenosis measurements were stratified into ranges: normal, mild (1-49%), moderate (50-69%), severe (70-99%) and occlusion. Results: We studied 130 patients who underwent both DUS and catheter angiography for assessment of carotid arteries (mean age, 64±11 years; 67% men; median time between DUS and angiography, 1 day [interquartile range, 2.5]). To date, fifty-two carotid artery pairs were independently rated and available for comparative analysis. Compared with catheter angiography, DUS had the following positive (PPV) and negative predictive values (NPV): PPV 50% and NPV 72% (3 true positive, 3 false positive, 33 true negative, 13 false negative) for detection of moderate, and PPV 57% and NPV 77% (20 true positive, 15 false positive, 13 true negative, 4 false negative) for detection of severe stenosis. Conclusions: Our preliminary data indicate that the novel DEGUM multi-parametric ultrasonography criteria do not eliminate the need for a confirmatory test for identification of clinically relevant grades of extracranial ICA disease.

The rationale for operating on patients with carotid artery disease is to prevent stroke. It has been estimated that in 50 to 80% of patients who experience an ischemic stroke, the underlying cause is a lesion in the distribution of the carotid artery, usually in the vicinity of the carotid bifurcation. Appropriate identification and intervention could significantly reduce the incidence of ischemic stroke. Carotid endarterectomy for both symptomatic and asymptomatic carotid artery stenosis has been extensively evaluated in prospective, randomized trials. Surgical reconstruction of the carotid artery yields the greatest benefits when done by surgeons who can keep complication rates to an absolute minimum. The majority of complications associated with carotid arterial procedures are either technical or judgmental; accordingly, this review emphasizes the procedural aspects of planning and operation considered to be particularly important for deriving the best short- and long-term results from surgical intervention. Specifically, this review covers preoperative evaluation, operative planning, operative technique, postoperative care, follow-up, and alternatives to direct carotid reconstruction. Figures show carotid arterial procedures including recommended patient positioning, the commonly used vertical incision, the alternative transverse incision, mobilization of the sternocleidomastoid muscle to identify the jugular vein, palpation of the internal carotid artery, division of the structures between the internal and external carotid arteries to allow the carotid bifurcation to drop down, division of the posterior belly of the digastric muscle to yield additional exposure of the internal carotid artery, a graphic representation of the measurement of internal carotid artery back-pressure, a central infarct zone surrounded by an ischemic zone, shunt placement, open endarterectomy, eversion endarterectomy, repair of fibromuscular dysplasia, and repair of coiling or kinking of the internal carotid artery.
