Arterial dissections complicating cerebral angiography and cerebrovascular interventions. (1/120)

BACKGROUND AND PURPOSE: Iatrogenic dissections are an uncommon complication of cerebral angiography. We retrospectively reviewed 12 cases of arterial dissections complicating cerebral angiography and cerebrovascular interventions to evaluate the clinical course of these dissections. METHODS: Cases from a large tertiary center performing a large number of neurovascular procedures were collected retrospectively. The patients' medical records and imaging studies were reviewed, with particular attention given to the cause of the dissection, the development of ischemic events resulting from the dissection, and the treatment used. RESULTS: Each of nine dissections affected a vertebral artery, each of two affected an internal carotid artery, and one affected a common carotid artery. The prevalence of iatrogenic dissections was 0.4%. Seven of the dissections were noted at the time of contrast material injection for the filming of cerebral angiograms. The other five dissections occurred during catheter or wire manipulations for interventional neuroradiologic procedures. Five of the patients in our series were treated with IV administered heparin for 24 to 48 hours. The other seven patients had recently suffered acute intracranial hemorrhage or undergone neurosurgery and could not undergo anticoagulant therapy. None of the patients developed symptoms of ischemia, but one was later found to have an asymptomatic infarct in the territory supplied by the dissected artery. CONCLUSION: Arterial dissections are an uncommon complication of cerebral angiography and cerebrovascular interventions and usually have a benign clinical course.  (+info)

Surgical treatment of extracranial internal carotid artery aneurysms. (2/120)

PURPOSE: Extracranial internal carotid artery aneurysms (EICAs) can be treated by carotid ligation or surgical reconstruction. In the consideration of the risk of stroke after internal carotid artery (ICA) occlusion, the aim of this study was to report the results of reconstructive surgery for these aneurysms, including lesions located at the base of the skull. METHODS: From 1980 to 1997, 25 ICA reconstructions were performed for EICA: 22 male patients and 3 female patients (mean age, 54.4 years). The cause was atherosclerosis (n = nine patients), dysplasia (n = 12 patients), trauma (n = three patients), and undetermined (n = one patient). The symptoms were focal in 15 cases (12 hemispheric, three ocular), nonfocal in three cases (trouble with balance and visual blurring), and glossopharyngeal nerve compression in one case. Six cases were asymptomatic, including three cases that were diagnosed during surveillance after ICA dissection. In nine cases, the upper limit of the EICA reached the base of the skull. A combined approach with an ear, nose, and throat surgeon allowed exposure and control of the ICA. RESULTS: After operation, there were no deaths, one temporary stroke, two transient ischemic attacks, and 11 cranial nerve palsies (one with sequelae). The ICA was patent on the postoperative angiogram in all but one case. During follow-up (mean, 66 months), there were two deaths (myocardial infarction), one occurrence of focal epileptic seizure at 2 months, and one transient ischemic attack at 2 years. In December 1998, duplex scanning showed patency of the reconstructed ICA in all but one surviving patient. CONCLUSION: Surgical reconstruction is a satisfactory therapeutic choice for EICA, even when located at the base of the skull.  (+info)

Surgical treatment of 50 carotid dissections: indications and results. (3/120)

PURPOSE: This article analyzes the course of 48 patients with 49 chronic carotid dissections (who were treated surgically at our institution after a median anticoagulation period of 9 months because of a persistent high-grade stenosis or an aneurysm) and the course of one additional patient with acute carotid dissection (who underwent early operative reconstruction 12 hours after onset because of fluctuating neurologic symptoms). METHODS: All medical and surgical records and imaging studies were reviewed retrospectively. All histologic specimens were reevaluated by a single pathologist to assess the cause of dissection. Follow-up of 41 patients (85%) after 70 months (range, 1-190 months) consisted of an examination of the extracranial vessels in the neck by Doppler ultrasound scanning and a questionnaire about the patients' medical history and their personal appraisals of cranial nerve function. RESULTS: Seventy percent of the dissections had developed spontaneously; 18% were caused by trauma; 12% of all patients (22% of the women) had a fibromuscular dysplasia. Indication for surgery was a high-grade persisting stenosis and a persisting or newly developed aneurysm. Flow restoration was achieved by resection and vein graft replacement in 40 cases (80%) and thromboendarterectomy and patch angioplasty in three cases (6%). Gradual dilatation was performed and effective in two cases (4%). Five internal carotid arteries (10%) had to be clipped because dissection extended into the skull base. One patient died of intracranial bleeding. Five patients (10%) experienced the development of a recurrent minor stroke (ipsilateral, 4 patients; contralateral, 1 patient). Cranial nerve damage could not be avoided in 29 cases (58%) but were transient in most of the cases. During follow-up, one patient died of unrelated reasons, and only one patient had experienced the development of a neurologic event of unknown cause. CONCLUSION: Chronic carotid dissection can be effectively treated by surgical reconstruction to prevent further ischemic or thromboembolic complications, if medical treatment for 6 months with anticoagulation failed or if carotid aneurysms and/or high-grade carotid stenosis persisted or have newly developed.  (+info)

Endovascular management of extracranial carotid artery dissection achieved using stent angioplasty. (4/120)

BACKGROUND AND PURPOSE: Dissection of the carotid artery can, in certain cases, lead to significant stenosis, occlusion, or pseudoaneurysm formation, with subsequent hemodynamic and embolic infarcts, despite anticoagulant therapy. We sought to determine the therapeutic value of stent-supported angioplasty retrospectively in this subset of patients who are poor candidates for medical therapy. METHODS: Five men and five women (age range, 37-83 years; mean age, 51.2 years) with dissection of the internal (n=9) and common (n=1) carotid artery were successfully treated with percutaneous endovascular balloon angioplasty and stent placement. The etiology was spontaneous in five, iatrogenic in three, and traumatic in two. Seven of the treated lesions were left-sided and three were right-sided. RESULTS: The treatment significantly improved dissection-related stenosis from 74+/-5.5% to 5.5+/-2.8%. Two occlusive dissections were successfully recanalized using microcatheter techniques during the acute phase. Multiple overlapping stents were needed in four patients to eliminate the inflow zone and false lumen and establish an angiographically smooth outline within the true lumen. There was one case of retroperitoneal hemorrhage, but there were no procedural transient ischemic attacks (TIAs), minor or major strokes, or deaths (0%). Clinical outcome at latest follow-up (16.5+/-1.9 months) showed significant improvements compared with pretreatment modified Rankin score (0.7+/-0.3 vs 1.8+/-0.44) and Barthel index (99.5+/-0.5 vs 80.5+/-8.9). One delayed stroke occurred in a treated patient with contralateral carotid occlusion following a hypotensive uterine hemorrhage at 8 months; the remaining nine patients have remained free of TIA or stroke. CONCLUSION: In select cases of carotid dissection associated with critical hemodynamic insufficiency or thromboembolic events that occur despite medical therapy, endovascular stent placement appears to be a safe and effective method of restoring vessel lumen integrity, with good clinical outcome.  (+info)

Traumatic bilateral internal carotid artery dissection following airbag deployment in a patient with fibromuscular dysplasia. (5/120)

This case describes a 39-yr-old male, presenting with left hemiplegia after a road traffic accident involving frontal deceleration and airbag deployment. Brain computerized tomography (CT) scan revealed a right parietal lobe infarct. Contrast angiography demonstrated bilateral internal carotid artery dissection and fibromuscular dysplasia. The patient was treated with systemic heparinization. Neurological improvement, evidenced by full return of touch sensation, proprioception and nociception began 10 days after the injury. To our knowledge, this is the first case report of carotid artery dissection associated with airbag deployment. Forced neck extension in such settings may result in carotid artery dissection because of shear force injury at the junction of the extracranial and intrapetrous segments of the vessel. Clinicians should consider carotid artery injury when deterioration in neurological status occurs after airbag deployment. We propose that the risk of carotid artery dissection was increased by the presence of fibromuscular dysplasia.  (+info)

Aneurysmal forms of cervical artery dissection : associated factors and outcome. (6/120)

BACKGROUND AND PURPOSE: The natural history of aneurysmal forms of cervical artery dissection (CAD) is ill defined. The aims of this study were to assess (1) clinical and anatomic outcome of aneurysmal forms of extracranial internal carotid artery (ICA) and vertebral artery (VA) dissections and (2) factors associated with aneurysmal forms of CAD. METHODS: Seventy-one consecutive patients with CAD were reviewed. Aneurysmal forms of CAD were identified from all available angiograms by 2 neuroradiologists. The frequency of arterial risk factors, of multiple vessel dissections, and of artery redundancies was compared in patients with and without aneurysm. Patients with aneurysm were invited by mail to undergo a final clinical and radiological evaluation. RESULTS: Of the 71 patients, 35 (49.3%) had a total of 42 aneurysms. Thirty aneurysms were located on a symptomatic artery (ICA, 23; VA, 7) and 12 on an asymptomatic artery (ICA, 10; VA, 2). Patients with aneurysm had multiple dissections of cervical vessels (18/35 versus 7/36; P:=0.005) and arterial redundancies (20/35 versus 11/36; P:=0.02) more frequently than patients without aneurysm. They were also more often migrainous (odds ratio=2.7 [95% CI, 0.8 to 8.5]) and tobacco users (odds ratio=2.2 [95% CI, 0.7 to 6.3]). Clinical and anatomic follow-up information was available for 35 (100%) and 33 patients (94%), respectively. During a mean follow-up of >3 years, no patient had signs of cerebral ischemia, local compression, or rupture. At follow-up, 46% of the aneurysms involving symptomatic ICA were unchanged, 36% had disappeared, and 18% had decreased in size. Resolution was more common for VA than for ICA aneurysms (83% versus 36%). None of the aneurysms located on an asymptomatic ICA had disappeared. CONCLUSIONS: Although aneurysms due to CAD frequently persist, patients carry a very low risk of clinical complications. This favorable clinical outcome should be kept in mind before potential harmful treatment is contemplated.  (+info)

Mild hyperhomocyst(e)inemia: a possible risk factor for cervical artery dissection. (7/120)

BACKGROUND AND PURPOSE: The pathogenesis of cervical artery dissection (CAD) remains unknown in most cases. Hyperhomocyst(e)inemia [hyperH(e)], an independent risk factor for cerebrovascular disease, induces damage in endothelial cells in animal cell culture. Consecutive patients with CAD and age-matched control subjects have been studied by serum levels of homocyst(e)ine and the genotype of 5,10-methylenetetrahydrofolate reductase (MTHFR). METHODS: Twenty-six patients with CAD, admitted to our Stroke Unit (15 men and 11 women; 16 vertebral arteries, 10 internal carotid arteries), were compared with age-matched control subjects. All patients underwent duplex ultrasound, MR angiography, and/or conventional angiography. RESULTS: Mean plasma homocyst(e)ine level was 17.88 micromol/L (range 5.95 to 40.0 micromol/L) for patients with CAD and 6.0+/-0.99 micromol/L for controls (P:<0.001). The genetic analysis for the thermolabile form of MTHFR in CAD patients showed heterozygosity in 54% and homozygosity in 27%; comparable figures for controls were 40% (P:=0.4) and 10% (P:=0.1), respectively. CONCLUSIONS: Mild hyperH(e) might represent a risk factor for cervical artery dissection. The MTHFR mutation is not significantly associated with CAD. An interaction between different genetic and environmental factors probably takes place in the cascade of pathogenetic events leading to arterial wall damage.  (+info)

Thrombolytic therapy for acute extra-cranial artery dissection: report of two cases. (8/120)

Extra-cranial arterial dissection accounts for 10% of strokes in young people. Information on safety of thrombolytic administration in this group is limited. The literature, however, does not favor use of thrombolytics for myocardial ischemia when peripheral arterial dissection coexists. Based on the clinical and radiological features, two patients who presented with acute stroke secondary to arterial dissection were considered for thrombolysis. One of them received intra-venous recombinant tissue plasminogen activator (rtPA), and the other patient received intra-arterial rtPA. There were no post thrombolysis complications. This report supports feasibility of administering thrombolytics in acute ischemic strokes resulting from extra-cranial arterial dissection. Future larger studies are necessary to determine the efficacy, safety and long-term outcome in this patient population.  (+info)

Two cases are reported in which the diagnosis of a serious condition was delayed as the symptoms had been attributed to migraine. Spontaneous carotid artery dissection is a serious but treatable cause of headache that may be misdiagnosed as recent onset migraine.

Carotid artery dissection is a significant cause of ischemic stroke in all age groups.Spontaneous internal carotid artery dissection is a common cause of ischemic stroke in patients younger than 50 years and accounts for up to 25% of ischemic strokes in young and middle-aged patients. Dissection of the internal carotid artery can occur intracranially or extracranially, with the latter being more frequent. Internal carotid artery dissection can be caused by major or minor trauma, or it can be spontaneous in which case genetic, familial, and/or heritable disorders are likely etiologies. Patients can present in a variety of settings, such as a trauma bay with multiple traumatic injuries; their physicians office with nonspecific head, neck, or face pain; or to the emergency department with a partial Horner syndrome. A high index of suspicion is required to make this difficult diagnosis. Sophisticated imaging techniques, which have improved over the last two decades, are required to confirm the ...
TY - JOUR. T1 - Isolated vagus nerve paralysis associated with internal carotid artery dissection. AU - Nakagawa, Hideki. AU - Kusuyama, Toshiyuki. AU - Ogawa, Kaoru. PY - 2014/2/1. Y1 - 2014/2/1. N2 - Dysphagia and hoarseness caused by laryngopharyngeal paralysis associated with internal carotid artery (ICA) dissection is rare. We reported a case which recovered spontaneously. A 57-year old man visited our hospital complaining of dysphagia and hoarseness lasting for two weeks. Paralysis of right vocal fold and rotational movement of the posterior pharyngeal wall toward the left side during swallowing were observed. Magnetic resonance imaging was performed under diagnosis of isolated right vagus nerve paralysis, and dissection of the right ICA was revealed. He was treated conservatively, and both of laryngopharyngeal movement and the ICA dissection were improved completely. There is a possibility that laryngeal paralysis caused by ICA dissection has been misdiagnosed as an idiopathic ...
In this prospective observational study, we found: (1) complete recanalization occurred in 160 (60%) of 268 SICAD; (2) complete recanalization occurred within the first 6 months but not thereafter; and (3) occlusive SICAD was less likely to recanalize, whereas SICAD presenting with local symptoms and signs only was independently associated with recanalization.. The 60% complete recanalization rate of SICAD observed in this investigation is similar to the results of previous smaller ultrasound studies.10,23 Steinke et al10 observed 48 patients with 50 SICAD who were treated with anticoagulation for an average period of 51 days. Complete recanalization was found in 34 (68%) patients. Sturzenegger et al23 followed-up 43 patients with 44 SICAD during a mean interval of 15 months and reported complete recanalization in 25 (63%) of 40 patients. Desfontaines et al26 surveyed 60 patients with SICAD (spontaneous, n=50; traumatic, n=10) who were using anticoagulation in 34 cases for a mean time period of ...

Clinical features of carotid artery dissection include ipsilateral local signs, contralateral ischemic stroke, or both. We observed two patients in whom these features were associated with renal infarcts.. A 57-year-old woman had painful Horners syndrome caused by a right internal carotid artery dissection. On days 3 and 4 she had acute abdominal pain, first on the right side and later on the left. The computed tomographic (CT) scan showed a left renal infarct. No aortic dissection or cardiac source of embolism was found. Transesophageal echocardiography showed a mild dystrophy of the ascending aorta and of the mitral valve. Cerebral angiography showed irregularities of the V3 segment of the left vertebral artery compatible with fibromuscular dysplasia. Erythrocyte sedimentation rate was 100 mm/h, and she complained of intense fatigue. She fully recovered within 3 months. A 53-year-old man had sudden severe abdominal pain followed by headache and difficulty in swallowing. He had 9th, 10th, ...
Spontaneous internal carotid artery (ICA) dissection (sICAD) results from an intimal tear located around the distal carotid sinus. The mechanisms causing the tear are unknown. This case-control study tested the hypotheses that head movements increase the wall stress in the cervical ICA and that the stress increase is greater in patients with sICAD than in controls. Five patients with unilateral, recanalized, left sICAD and five matched controls were investigated before and after maximal head rotation to the left and neck hyperextension after 45° head rotation to the left. The anatomy of the extracranial carotid arteries was assessed by magnetic resonance imaging and used to create finite element models of the right ICA. Wall stress increased after head movements. Increases above the 80th and 90th percentile were located at the intimal side of the artery wall from 7.4 mm below to 10 mm above the cranial edge of the carotid sinus, i.e., at the same location as histologically confirmed tears in ...
The most common clinical manifestation of symptomatic ICAD and VAD was headache (68% of patients with ICAD and 69% of those with VAD). It was the initial manifestation in 47% of the patients with ICAD and in 33% of those with VAD. Neck pain was more common with VAD (46%) than with ICAD (26%). The pain in ICAD typically was ipsilateral and distributed over the anterior head, whereas that in VAD was either ipsilateral or bilateral and typically distributed over the posterior head region. Constant pain (aching, pressing, or sharp in quality) was more common than pulsating pain. The headache was considered unique by 62% of patients with ICAD and by 50% of those with VAD.. The frequent occurrence of frontotemporal headaches and orbital, facial, and ear pain in patients with ICAD is consistent with the observation that stimulation of the carotid artery bifurcation can produce pain referred to these areas. [25] The predominantly occipital distribution of headache in VAD may be explained by the upper ...

Dissection of the carotid and vertebral arteries is a rare entity with less than 5 new cases per 100.000 of the general population every year. However, it represents an important cause of cerebral ischaemia in young and middle-aged patients. Carotid dissection may either be associated with aortic dissection or may exclusively affect the carotid artery, either caused by trauma or occurring spontaneously.[1] US may be more than 90% sensitive in the diagnosis of carotid dissection, thus being a reliable technique to exclude the presence of this entity. Nevertheless, definite diagnosis and the extent of disease should always be evaluated with a cross-sectional imaging technique such as computed tomography angiography or magnetic resonance angiography.[2, 3] One characteristic but indirect finding of carotid dissection is the detection of a high resistance flow pattern at the initial part of the internal carotid artery, suggestive of distal occlusion or high-grade stenosis. This is explained by the ...

Add in my uncontrollable fear of dying that day because of the carotid dissection, my fear of having a stroke and ending up like some of the people I saw when I was at that rehab facility for my hip, the fear of having an angiogram - it was not good. I wasnt in pain from a broken bone or surgery this time, so no morphine to help me sleep/mute my annoyance and stress. Just the disgusting, hot, sweaty bed with head/leg controllers that were next to my head, so really difficult for me to twist and reach. People coming in every 20 minutes nearly all night to take my blood pressure, draw blood, insert an IV, whatever. A room right next to the heart monitor screen for the nurses, a screen that beeped. A lot. Loudly. I was so exhausted from getting up so early for the CT and then I couldnt sleep. Saturday was even worse. I was told morning angiogram. That turned into 1 pm.

BACKGROUND AND PURPOSE: Isolated Horner syndrome without associated cranial nerve palsies or ischemic symptoms is an important presentation of spontaneous internal carotid artery dissection (sICAD). Ultrasound is often used as a screening method in these patients because cervical MRI is not always available on an emergency basis. Current knowledge on ultrasound findings in patients with sICAD presenting with isolated Horner syndrome is limited. METHODS: Patients were recruited from prospective cervical artery dissection databases of 3 tertiary care centers. Diagnosis of sICAD was confirmed by cervical MRI and MR angiography or digital subtraction angiography in all patients. Data on Doppler sonography and color duplex sonography examinations performed within 30 days of symptom onset were analyzed. RESULTS: We identified 88 patients with Horner syndrome as the only sign of sICAD. Initial ultrasound examination was performed in 72 patients after a mean time interval from symptom onset to ...
Internal carotid artery dissection has been well recognized as a major cause of ischaemic stroke in young and middle-aged adults. However, internal carotid artery dissection induced hypoglossal nerve palsy has been seldom reported and may be difficult to diagnose in time for treatment; even angiography sometimes misses potential dissection, especially when obvious lumen geometry changing is absent. We report a 42-year-old man who presented with isolated hypoglossal nerve palsy. High-resolution MRI showed the aetiological dissected internal carotid artery. In addition, a potential genetic structural defect of the arterial wall was suggested due to an exon region mutation in the polycystic-kidney-disease type 1 gene. Hypoglossal nerve palsy is a rare manifestations of carotid dissection. High-resolution MRI may provide useful information about the vascular wall to assist in the diagnosis of dissection. High-throughput sequencing might be useful to identify potential cerebrovascular-related gene mutation,

Background: Spontaneous cervicocephalic artery dissection (sCAD) of more than two cervical arteries is rare.. Patients and methods: Vascular and potential sCAD risk factors, triggering events, clinical and neuroimaging findings, and outcome of patients with multiple sCAD were studied. Patients were drawn from prospective hospital-based sCAD registries.. Results: Of 740 consecutive patients with sCAD, 11 (1.5%) had three, and one had four (0.1%) sCAD. Eight of these 12 patients were women. One patient had additional dissections of the celiac trunk and hepatic artery. Vascular risk factors included hypertension (n = 1), hypercholesterolaemia (n = 6), current smoking (n = 5) and migraine (n = 6). No patient had a family history of sCAD, fibromuscular dysplasia (FMD) or connective tissue disease. SCAD was preceded by a minor trauma in five and infection in four patients. Clinical manifestations included ischaemic stroke (n = 8), transient ischaemic attack (n = 3), headache (n = 9), neck pain (n = ...

Introduction. Cervical artery dissection (CAD) is responsible for 2% to 3% of all ischaemic strokes in the general population and 10% to 25% of ischaemic strokes in patients younger than 50 years.1,2 Arteriography has traditionally been the diagnostic tool of choice for CAD. However, new and less invasive techniques, including magnetic resonance imaging (MRI), computerised tomography (CT) angiography, and ultrasonography studies, have replaced conventional arteriography in daily clinical practice. Despite the above, none of these new techniques has proved more sensitive than another for diagnosing CAD. As a result, conventional arteriography is still considered the gold standard.3,4. Intravenous thrombolysis is a safe treatment in the acute phase of CAD-related strokes.5-7 However, CAD-related ischaemic stroke patients treated with systemic thrombolysis show poorer clinical progress due to frequent tandem intracranial internal carotid artery/middle cerebral artery occlusions.6,8 Experience with ...

Patients with internal carotid artery dissection (ICAD) were older (p , 0.0001), more often men (p = 0.006), more frequently had a recent infection (odds ratio [OR] = 1.59 [95% confidence interval (CI) 1.09-2.31]), and tended to report less often a minor neck trauma in the previous month (OR = 0.75 [0.56-1.007]) compared to patients with VAD. Clinically, patients with ICAD more often presented with headache at admission (OR = 1.36 [1.01-1.84]) but less frequently complained of cervical pain (OR = 0.36 [0.27-0.48]) or had cerebral ischemia (OR = 0.32 [0.21-0.49]) than patients with VAD. Among patients with CEAD who sustained an ischemic stroke, the NIH Stroke Scale (NIHSS) score at admission was higher in patients with ICAD than patients with VAD (OR = 1.17 [1.12-1.22]). Aneurysmal dilatation was more common (OR = 1.80 [1.13-2.87]) and bilateral dissection less frequent (OR = 0.63 [0.42-0.95]) in patients with ICAD. Multiple concomitant dissections tended to cluster on the same artery type rather ...
A young woman 38 years of age underwent Doppler ultrasonography following the spontaneous appearance of cervical pain causing loss of sleep. The examination revealed bilateral dissection of the internal carotid arteries, confirmed by supraaortic arteriography. Two successive CT scans showed no cerebral lesions. A thrombosis of the great saphenous vein was recorded as the only vascular event in her medical history. Thrombophilia was assessed following discovery of the dissection, and upon examination a heterozygotic mutation of Factor V Leiden was revealed. This observation is the second case of carotid dissection occurring in a subject presenting a factor V mutation. At the present time, however, there are no results to justify the assumption of a direct link between these two pathologies.

From the eMedicine site: The typical presentation of VAD is a young person with severe occipital headache and posterior nuchal pain following a recent, relatively minor, head or neck injury. The trauma is generally from a trivial mechanism but is associated with some degree of cervical distortion. Focal neurologic signs attributable to ischemia of the…
TY - JOUR. T1 - Arterial dissections complicating cerebral angiography and cerebrovascular interventions. AU - Cloft, Harry J.. AU - Jensen, Mary E.. AU - Kallmes, David F. AU - Dion, Jacques E.. PY - 2000. Y1 - 2000. N2 - BACKGROUND AND PURPOSE: Iatrogenic dissections are an uncommon complication of cerebral angiography. We retrospectively reviewed 12 cases of arterial dissections complicating cerebral angiography and cerebrovascular interventions to evaluate the clinical course of these dissections. METHODS: Cases from a large tertiary center performing a large number of neurovascular procedures were collected retrospectively. The patients medical records and imaging studies were reviewed, with particular attention given to the cause of the dissection, the development of ischemic events resulting from the dissection, and the treatment used. RESULTS: Each of nine dissections affected a vertebral artery, each of two affected an internal carotid artery, and one affected a common carotid artery. ...

METHODS: One hundred and sixty-one consecutive patients with unilateral ICAD causing severe stenosis or occlusion were examined clinically and by ultrasound 1 year after symptom onset. Forty-six cases with persistent and 46 age- and latency-matched cases with transient (recanalization complete or less than 50% stenosis) severe stenosis or occlusion of the ICA were enrolled. Nine patients with surgical, endovascular, or fibrinolytic therapy for ICAD or associated stroke were excluded. Antithrombotic therapy was given at the discretion of the treating physician. Clinical follow-ups were done annually. RESULTS: Antithrombotic therapy and follow-up were similar in patients with permanent (6.2 +/- ...

After finishing an intense workout, in the on-site work gym, Amy collapsed, hitting her head on the back of a fire truck. Her co-workers rushed to assist her, securing an ambulance to take her to the hospital.. Amy remembers everything about her ride to the hospital that day in the December 2012, recalling how her speech sounded slurred and garbled as though intoxicated. Once in the intensive care unit, she did not realize the severity of what happened. But, it wasnt long before she discovered she could not move the left side of her body. A CT scan revealed she had experienced an ischemic stroke from a carotid artery dissection. Doctors were unable to determine what caused this, and Amys good health made it even more puzzling.. After a few weeks in the acute care hospital, Amy knew she was ready for rehabilitation. She needed the best chance of getting back, so she chose MidAmerica Rehabilitation Hospital, an inpatient rehabilitation hospital in the Encompass Health network. Amy and her mother ...
We report a case of a 45-year-old man presenting with asomatognosia, or loss of body part ownership, when he experienced difficulty acknowledging that his arm was his own. His symptoms might easily have been considered to be of psychiatric origin. Instead they turned out to be due to highly focal stroke secondary to carotid dissection, an important and often missed cause of stroke in younger patients.

  • See also Overview of Aortic Aneurysms and Aortic Dissection. (
  • During treatment of vertebral artery (VA) fusiform aneurysms, it is critical to preserve peripheral perforators and anterograde blood flow of the VA and to reduce hemodynamic load to the contralateral VA. Even in the era of endovascular treatment, there are still many benefits to using microsurgical treatments with appropriate clip application and preservation of the perforators around the aneurysm, in conjunction with various bypass techniques. (
  • The term "vertebral artery fusiform aneurysm" (VAFA) is generally used for spindle-shaped aneurysms that arise from the main trunk of the vertebral artery (VA). However, the clinical and pathological definition is ambiguous and, confusingly, the term is currently used for various types of aneurysms with different clinical and pathological features, including wide-neck saccular, dolichoectatic, and giant serpentine aneurysms. (
  • The cardiologist should have an understanding of the recent developments in the treatment of carotid artery disease, aortic aneurysms, and chronic limb ischaemia. (
  • The patient should have their electrolytes and liver enzymes monitored during treatment and be followed with imaging studies, as aortic aneurysms and/or dissections are possible with GCA. (
  • Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the internal carotid artery and aneurysm formation. (
  • Fifty-eight consecutive patients with extracranial ICA dissection were reviewed, and those with radiographically detectable dissecting aneurysm at the acute stage or during early follow-up were included in this study. (

  • Secondly, right carotid angiography with digital compression of the left common carotid artery didn't demonstrate dissecting aneurysm at the left A1 segment, which suggested poor collateral flow through the anterior communicating artery (AcomA). (
  • This dissecting aneurysm involving A1 segment could not be wrapped by usual fashion because of the risk of injury to the nearby perforating arteries 10) and also could not be done trapping surgery because the collateral blood circulation in that territory of the distal right ACA seemed to be poor.

  • A 68 year old man with bilateral carotid stenosis is being considered for carotid endarterectomy. (
  • By contrast, angiotensin converting enzyme (ACE) inhibitors should be used with circumspection since between 30-50% of patients with aortic disease have renal artery stenosis. (
  • Subclavian steal syndrome (SSS) occurs when proximal subclavian artery stenosis or occlusion leads to reversal of flow in the ipsilateral vertebral artery. (
  • SSS may be caused by stenosis or occlusion of one or both subclavian arteries. (
  • Either the right or left subclavian artery may be affected, but stenosis of the left subclavian artery is four times more common than stenosis of the right, as it was found in one study to be left sided in 82.3% of subjects. (
  • Stenosis or occlusion of the proximal subclavian artery impedes blood flow distal to the occlusion. (
  • In this case, stenosis/occlusion of the subclavian artery causes retrograde flow of blood in the internal mammary artery to the subclavian artery, resulting in angina pectoris. (
  • [11] In 1961, a case report described two patients who experienced symptoms of cerebral ischemia secondary to stenosis of the subclavian artery who had subsequent retrograde flow in the ipsilateral vertebral artery. (

  • Additionally, a xenon CT scan with acetazolamide was performed that confirmed impaired cerebral vasoreactivity to the right hemisphere ( Fig 1 E ). Given that the patient had severe coronary disease, it was thought that general anesthesia and a superficial temporal artery to middle cerebral artery bypass surgery would be high risk. (

(
  • The internal carotid artery (C1 segment) enters the skull base through the carotid canal , where it begins a series of 90° turns which lead it to eventually terminate as the middle and anterior cerebral arteries . (
  • The terminal ICA (C7 segment) abruptly divides into the middle and anterior cerebral branches and gives off two smaller posterior branches, the anterior choroidal artery and the posterior communicating artery . (

  • Blood flow in the ipsilateral vertebral artery can be reversed if demand increases in the subclavian artery distal to the occlusion. (
  • The takeoff for the ipsilateral vertebral artery arises from the subclavian artery and is distal to the occlusion in SSS. (
  • Currently, the most commonly available imaging modalities are carotid ultrasonography and CT angiography (CTA) of the head and neck. (
  • However, the best method to diagnose an internal carotid artery dissection is a combination of CTA and magnetic resonance angiography (MRA) with fat-suppressed T1 images. (
  • [ 1 , 5 , 6 ] CTA and MRA are replacing conventional angiography in the diagnosis of internal carotid and vertebral artery dissection because the resolution and accuracy of CTA and MRA are similar to that of angiography. (
  • Additionally, MRI/MRA is superior to conventional angiography in diagnosing dissections without associated luminal abnormalities. (
  • Diagnosis of vertebral artery dissection (VAD) is usually made by neuroimaging, which has largely replaced conventional angiography in most centers. (
  • Data examining CTA versus magnetic resonance imaging-angiography (MRI-A)/MRA for VAD are limited, but there may be a slight preference for CTA for identifying VAD given the smaller arterial diameters compared to internal carotid dissections. (

  • What is Carotid Artery Disease - Stroke? (
  • What is Arm Artery Disease? (
  • A narrowing of the arteries from the build-up of plaque can lead to coronary heart disease, and can cause a heart attack when this occurs in the blood vessels leading to the heart. (
  • Narrowing of the arteries in other places, such as your legs, can cause what is called Peripheral Arterial Disease , or PAD. (
  • Peripheral arterial disease (PAD) occurs when atherosclerosis, or hardening of the arteries, causes a buildup of plaque in the blood vessels that carry oxygen and nutrients to all the tissues of the body. (
  • Similarly, the vascular surgeon should recognise the incidence of coronary artery disease in their patients presenting with peripheral vascular disease and the need for cardiological assessment. (
  • In this setting, there may be poor recognition among nursing and medical staff that these patients are at greater risk than general surgical patients because of the very high prevalence of significant, yet often occult, coronary artery disease. (
  • There has been controversy about how much preoperative investigation and intervention for coronary artery disease is of proven benefit in patients undergoing major vascular surgery. (
  • There is good evidence that if a patient has no previous history of coronary artery disease and a normal preoperative ECG, there is no benefit to preoperative invasive cardiological investigation. (
  • Modification of atherosclerotic risk factors is as important in peripheral arterial disease as in coronary artery disease, and all patients with symptomatic atherosclerosis should be on an antiplatelet agent (usually aspirin), appropriate antihypertensive treatment, and a statin if the fasting cholesterol is more than 3.5 mmol/l. (
  • Smoking is particularly closely associated with peripheral arterial disease, even more so than coronary artery disease, and up to 78% of cases of intermittent claudication can be attributed to smoking. (
  • There is also a coronary-subclavian steal syndrome, which occurs in the setting of a patient with severe atherosclerotic disease who has undergone a coronary artery bypass graft that uses the internal mammary artery. (
  • Mortality with Paclitaxel-Coated Devices in Peripheral Artery Disease. (
  • Most vascular disease is caused by atherosclerosis , a disease of the walls of the vessels, often called "hardening of the arteries. (
  • Coronary artery disease is the most common type of heart disease. (
  • Strokes can occur from carotid disease when plaque breaks off from the carotid artery and travels to the brain. (
  • Stroke symptoms related to carotid disease are sudden weakness or numbness of an arm or a leg, sudden inability to speak or find your words, trouble swallowing or sudden blindness in one eye. (
  • What are the treatment options for carotid artery disease? (
  • Treatment of carotid artery disease usually involves a combination of lifestyle changes including smoking cessation, cholesterol management and daily aspirin therapy. (
  • Peripheral vascular disease is associated with poor circulation or "hardening of the arteries" and can lead to a significant increased risk of stroke or heart attack. (
  • Outer artery disease (also called peripheral arterial illness) is a usual problem in which tightened arteries lower blood circulation to the arms or legs. (
  • In outer artery disease (PAD), the legs or arms- usually the legs- don't get sufficient blood flow to stay on par with demand. (
  • Peripheral artery disease is normally a sign of a buildup of fatty down payments in the arteries (atherosclerosis). (
  • If a tear occurs in the inner lining of the body's main artery (the aorta), blood enters the wall of the aorta, causing an aortic dissection. (
  • An aortic dissection occurs when blood surges into the wall of the aorta through a tear, causing the lining of the aorta to split. (
  • If a dissection occurs close to the heart where the aorta begins, it is particularly important that surgery be performed as soon as possible. (
  • An aortic dissection begins when a tear occurs in the innermost layer of the lining of the aorta. (
  • The aorta - the main artery in the body - has a shape like a wooden walking stick. (
  • If a rip occurs in the initial section of the aorta close to the heart or in the ascending portion, this is known as a type A aortic dissection. (
  • If lining is ripped in the descending portion of the aorta only, this is known as a type B dissection. (
  • The aorta, which is about 1 inch (2.5 centimeters) in diameter, is the largest artery of the body. (
  • Just after the aorta leaves the heart, smaller arteries that carry blood to the head and arms branch off. (
  • The aorta then arches down, with additional smaller arteries branching off along its route from the left ventricle to the lower abdomen at the top of the hipbone (pelvis). (
  • At this point, the aorta divides into the two iliac arteries, which supply blood to the legs. (
  • for example, where the abdominal aorta branches into the iliac arteries) or in areas of stress (for example, in the popliteal artery). (

  • Two transections of the vertebral arteries were embolized with coils and/or liquid embolic agent (acrylic glue). (
  • It arises from the vertebral arteries winding spirally within brackets. (
  • The blood flow from the contralateral vertebral artery also may reverse across the union of the vertebral arteries at the basilar artery. (
  • Carotid artery dissection is a separation of the layers of the artery wall supplying oxygen-bearing blood to the head and brain and is the most common cause of stroke in young adults. (
  • Once considered uncommon, spontaneous carotid artery dissection is an increasingly recognized cause of stroke that preferentially affects the middle-aged. (
  • Blood clots, or emboli, originating from the dissection are thought to be the cause of infarction in the majority of cases of stroke in the presence of carotid artery dissection. (
  • The role of carotid noninvasive tests in stroke prevention. (
  • Internal carotid artery dissection can lead to thrombus formation and the risk for distal embolization, whereas arterial narrowing with stroke due to inadequate blood flow is a less common mechanism of ischemia. (
  • With less that 200 patients participating, it would have been most amazing to see a case of arterial dissection or stroke. (
  • The most recent application of percutaneous intervention has been to explore its clinical utility and safety for stroke prevention in carotid arteries. (
  • It is likely that as the technology continues to evolve, the procedural risks of stroke and death will be minimized by embolic protection devices, making carotid stenting an option for low-risk surgical patients. (
  • At the Ochsner Clinic Foundation, we became interested in the feasibility of carotid stent placement to prevent stroke in January of 1994. (
  • Patients with hemodynamic impairment ipsilateral to a carotid occlusion are at a high risk of subsequent stroke, and currently 2 surgical options have been studied: extracranial-to-intracranial bypass and direct thromboendarterectomy. (
