Artery Dissection (artery + dissection)
Kinds of Artery Dissection Selected AbstractsPulmonary Artery Dissection: Echocardiographic Findings and DiagnosisECHOCARDIOGRAPHY, Issue 4 2003Daniel Areco Pulmonary artery dissection is a rare but life-threatening event, predisposing to sudden cardiac death or cardiogenic shock. It is often associated with underlying congenital disorders predisposing to pulmonary hypertension. Rarely, it is diagnosed by echocardiography or other image techniques. We present a case report of a pulmonary artery dissection, diagnosed primarily by echocardiography. The patient died soon after refusing any interventional approach after a short period under medication. (ECHOCARDIOGRAPHY, Volume 20, May 2003) [source] Cluster Headache and Internal Carotid Artery Dissection: Two Cases and Review of the LiteratureHEADACHE, Issue 3 2008Andrea Rigamonti MD We describe 2 patients with cluster headache attacks associated with a dissection of the ipsilateral internal carotid artery at the extra,intracranial passage. These cases highlight the need for extensive neuroradiological investigation in cluster headache patients when atypical features are present. We also performed a PubMed search to review the current literature data about this association. [source] Headache As Only Symptom in Multiple Cervical Artery DissectionHEADACHE, Issue 5 2001Maarten Buyle MD We describe a patient with atypical headache as the only presenting symptom of spontaneous triple cervical artery dissection. As the patient suffered from arterial hypertension, a causative relation between headache and arterial hypertension was initially taken into consideration. However, four-vessel arteriography disclosed a dissection of both internal carotid arteries and the right vertebral artery. This unique case highlights the value of conventional arteriography for diagnosing cervical artery dissection. Since multiple cervical artery dissections are not rare, all cervical arteries should be examined by means of conventional arteriography when a dissection is suspected.

Debette Background Cervical artery dissection (CAD) is a frequent cause of ischemic stroke, and occasionally death, in young adults. Several lines of evidence suggest a genetic predisposition to CAD. However, previous genetic studies have been inconclusive mainly due to insufficient numbers of patients. Our hypothesis is that CAD is a multifactorial disease caused by yet largely unidentified genetic variants and environmental factors, which may interact. Our aim is to identify genetic variants associated with an increased risk of CAD and possibly gene,environment interactions. Methods We organized a multinational European network, Cervical Artery Dissection and Ischemic Stroke Patients (CADISP), which aims at increasing our knowledge of the pathophysiological mechanisms of this disease in a large group of patients. Within this network, we are aiming to perform a de novo genetic association analysis using both a genome-wide and a candidate gene approach. For this purpose, DNA from approximately 1100 patients with CAD, and 2000 healthy controls is being collected. In addition, detailed clinical, laboratory, diagnostic, therapeutic, and outcome data are being collected from all participants applying predefined criteria and definitions in a standardized way. We are expecting to reach the above numbers of subjects by early 2009. Conclusions We present the strategy of a collaborative project searching for the genetic risk factors of CAD. The CADISP network will provide detailed and novel data on environmental risk factors and genetic susceptibility to CAD.

The symptoms of HC typically respond dramatically to indomethacin therapy. We describe a patient with traumatic internal carotid artery dissection, who presented with a clinical picture mimicking HC that initially responded to indomethacin. Patients with a clinical picture similar to HC should be managed with a high index of suspicion for a possible cervical arterial dissection.

To determine the value of color Doppler sonography (CDUS) in the diagnosis and follow-up of patients with extracranial and intracranial vertebral artery (VA) dissection. Method. Thirty-three patients aged 42 ± 12 years with 40 VADS confirmed via digital subtraction angiography (DSA) (n = 37) and magnetic resonance angiography (MRA) (n = 3) were included in the study. All patients were investigated with extracranial CDUS and transcranial CDUS (TCCDUS) over a mean ± SD follow-up period of 42 ± 24 months and occurrence of new ischemic symptoms was assessed. Sonographic results were compared with initial and follow-up angiographic results. Results. At presentation, 24/33 (73%) patients had suffered an ischemic stroke, 5/33 (15%) had a transient ischemic attack (TIA), and 4/33 (12%) were asymptomatic. Two patients had a recurrent vertebrobasilar TIA; there was no recurrent stroke. The initial DSA findings consisted of 14 stenoses, 20 tapered occlusions, and 6 pseudoaneurysms. During follow-up, 63% of the vessels recanalized. Sonographic findings were consistent with angiographic findings in 80% at the initial examination and in 86% during follow-up. The main reason for discordant results was the failure of CDUS to detect pseudoaneurysms. No recurrence occurred in the vertebral arteries (VA), but 1 patient had an asymptomatic carotid artery dissection during follow-up. Conclusion. Recurrent TIA or stroke after VAD appears to be extremely rare, independent of recanalization or persistent occlusion of the affected artery. CDUS and TCCDUS provide reliable follow-up of VAD in all patients presenting with stenosis or occlusion, but do not allow for detection of pseudoaneurysms of the VA. © 2008 Wiley Periodicals, Inc.

(J Interven Cardiol 2004;17:123,127) [source] Spontaneous coeliac artery dissectionJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 4 2006B McGuinness Summary A patient with spontaneous coeliac artery dissection that presented as upper abdominal pain is reported. This was diagnosed on contrast-enhanced multislice helical CT. The patient was treated conservatively and follow-up CT showed mild aneurysmal change of the splenic artery and a small splenic infarct. Isolated dissection of the visceral arteries (and, in particular, the coeliac artery) is extremely rare. With such limited evidence, decisions over best management are difficult, but depend on initial severity and progression at follow up. [source] The Impact of Surgery in the Management of the Head and Neck Carcinoma Involving the Carotid Artery,THE LARYNGOSCOPE, Issue 10 2008Enver Ozer MD Abstract Objectives/Hypothesis: To demonstrate the feasibility of the carotid artery dissection and/or resection and reanastomosis, and to show its positive impact on survival and disease control rates for the head and neck carcinomas involving the carotid artery. Study Design: Tertiary center (Comprehensive Cancer Center). Case series review. Methods: The data of 90 patients with head and neck malignancies involving the carotid artery were operated for the carotid artery dissection and/or resection, and reanastomosis in the last 10 years were retrospectively reviewed and analyzed. Results: Eighty (89%) of the 90 patients' head and neck malignancies were squamous cell carcinoma. Fifty-two (65%) and 28 (35%) of 80 patients were recurrent and stage IV disease, respectively. There was no stage I to III disease. Carotid artery was dissected and preserved in 64 (71.1%) of the 90 patients. Eighteen (20%) of 90 patients needed carotid artery dissection with resection and reanastomosis. Eight (8.9%) patients were unresectable. Sixty (75%) of 80 patients needed reconstruction with regional or free flaps and grafts. Overall 2- and 5-year estimated survivals were 32.4% and 27.8% for all; 14.3% and 10.7% for recurrent; 64.3% and 57.8% for stage IV previously untreated; and 22.0% and 22.0% for carotid artery resected-reanastomosed patients, respectively. Conclusions: The carotid artery dissection without resection is an achievable goal in majority of patients with the advanced stage head and neck carcinoma involving the carotid artery. Resection and reanastomosis of carotid artery, especially in the previously untreated carotid involved patients, is a feasible surgery and achieves better survival and disease control rates when compared with the unresected or recurrent disease patients. [source] Natural History of a Giant Coronary Aneurysm With Spontaneous DissectionCLINICAL CARDIOLOGY, Issue 12 2009Alberto Bouzas-Mosquera MD Primary spontaneous coronary artery dissection may appear in young women during the peripartum period or as a result of atherosclerosis. We present a patient with familial hypercholesterolemia who developed a giant aneurysm of the right coronary artery in the setting of atherosclerotic spontaneous coronary dissection over an 8 year period. This report illustrates the association between spontaneous coronary artery dissection and subsequent coronary aneurysm formation. Copyright © 2009 Wiley Periodicals, Inc. [source] Postpartum dissection of the left main coronary arteryCLINICAL CARDIOLOGY, Issue 4 2006Ian S. Rogers M.D., M.B.A. Abstract Peripartum coronary artery dissection is rare, but it is an increasingly recognized risk to women of childbearing age. Literature reviews reveal that about 80% of the population with spontaneous coronary artery dissections (SCAD) are female, and approximately 25,33% of cases occurred while the woman was pregnant or in the peripartum phase. Most cases have presented within 2 weeks of delivery. The left anterior descending is the most commonly affected vessel. The etiology is poorly understood, but many reports suggest that SCAD occurs as a result of protease release secondary to an eosinophilic vasculitis resulting in vessel lysis. Many investigators have examined the correlation between peripartum SCAD and estrogen levels; however, case studies have shown conflicting results regarding estrogen levels as the putative causative factor. Optimal treatment remains controversial. Presently, stenting appears to be best employed in the patients who have single-vessel dissection not involving the left main coronary artery (LMCA). Surgical revascularization via coronary artery bypass graft remains the optimal therapy in patients whose dissection involves the LMCA, in patients with concurrent multi-vessel dissection, and in patients with disease refractory to medical management. It is important to consider coronary artery dissection in the differential of any young woman who presents with signs or symptoms consistent with acute coronary syndrome, particularly if she is peripartum. Furthermore, once suspected, it is imperative that a definitive diagnostic study, that is, coronary angiography, be completed prior to the initiation of treatment whenever possible. [source] Spontaneous coronary artery dissectionCLINICAL CARDIOLOGY, Issue 7 2004Francis Q. Almeda M.D. Abstract Spontaneous coronary artery dissection (SCAD) is an unusual cause of acute myocardial ischemia with complex pathophysiology. This paper reviews the major diagnostic and therapeutic issues of this rare but important disease. The diagnosis of SCAD should be strongly considered in any patient who presents with symptoms suggestive of acute myocardial ischemia, particularly in young subjects without traditional risk factors for coronary artery disease (especially in young women during the peripartum period or in association with oral contraceptive use). Urgent coronary angiography is indicated to establish the diagnosis and to determine the appropriate therapeutic approach. The decision to pursue medical management, percutaneous coronary intervention, or surgical revascularization is based primarily on the clinical presentation, extent of dissection, and amount of ischemic myocardium at risk.
