164 Possible Causes for Intima, Tunica

Show results in: Deutsch

  • Arteriosclerosis

    OBJECTIVES: To assess and compare the prevalence of atherosclerosis evaluated by the intima-media thickness of carotid and femoral arteries, and by the ankle-brachial pressure[] It differs from the more common atherosclerosis in that the tunica intima remains unaffected; hence, the vessel lumen is preserved.[] The descending thoracic and abdominal aorta showed marked thrombogenic, lamellar thickening of the intima.[]

  • Medial Sclerosis

    DDx: Atherosclerosis (severe) - intimal hyperplasia with stenosis, calcifications typically in tunica intima. Images MCS - low mag. (WC) MCS - intermed. mag.[] Lo J, Dolan SE, Kanter JR et al (2006) Effects of obesity, body composition, and adiponectin on carotid intima-media thickness in healthy women.[] PATHOGENESIS Calcium deposits are found in the muscular layer (tunica media) of medium-sized arteries like femoral, radial, ulnar, and tibial artery.[]

  • Generalized Arterial Calcification of Infancy

    Calcification extended from the internal elastic lamina into the intima and media and was associated with a giant-cell reaction and smooth muscle proliferation.[] Due to extensive calcification of the arterial tunica media associated with intimal proliferation, the defect leads to vascular occlusions.[] Idiopathic infantile arterial calcification (IIAC) is a rare disease that is characterized by calcification in the media and fibroproliferative changes in the intima of larger[]

  • Carotid Artery Dissection

    Discussion Blood flows through the cleft of the carotid artery intima and into the cystic degeneration of the vascular media, thus forming a carotid artery dissection.[] We report a case of left carotid artery dissection and AIS originating from localized aortic arch dissection, pathologically caused by cystic medial necrosis in the tunica[] […] media and tunica intima of a vessel.[]

  • Fibromuscular Dysplasia

    The pathophysiological changes in the intima and media alter the vessel's elasticity and may adversely affect the lesion's response to balloon dilatation and stenting.[] KEYWORDS: Fibromuscular dysplasia; Papillary muscle; Papillary muscle arteries; Tunica media[] Dysplasia of the intima, media, or adventitia layer of the affected arteries causes stenosis and hypertension.[]

  • Cystic Medial Necrosis of the Aorta

    DISSECTION Blood vessel wall Intima Media Adventitia Blood gets through intima, rips across media, dissecting the wall Mostly occurs in proximal 10cm of aorta As right beside[] The tunica adventitia (yellow at bottom of image) with vaso vasorum is also seen. Movat's stain .[] Most cases of aortic dissections are associated with a tear in the intima of the vessel through which blood penetrates the wall of the vessel with propogation along the media[]

  • Aortic Dissection

    Perfusion CT-imaging showed a dilatation of the aortic arch and intraluminal structures indicating an intima flap of aortic dissection.[] RESULTS: We revealed a characteristic distribution pattern of PCSK9 in atherosclerotic plaques and the degenerated tunica media in AAD tissues, which was rarely observed in[] Introduction Thoracic aortic dissection occurs when the intima of the aorta becomes compromised and “tears” or “dissects” a new layer that fills with blood between the intima[]

  • Persistent Pupillary Membrane

    Vol. 5, No. 6 (2009-01 - 2009-02) Contents Editorial A Correlation of Common Carotid Intima Media Thickness with Risk Factors for Atherosclerosis in Type 2 Diabetes Mellitus[] Abstract During fetal development the lens receives nourishment through a vascular net called "tunica vasculosa lentis" which forms the pupillary membrane on its anterior[] […] exudates readily loosened from underlying tissue, as in croupous or pseudomembranous inflammation. fenestrated membrane one of the perforated elastic sheets of the tunica intima[]

  • Calciphylaxis

    Calcifications were most often noted in the tunica media (n   8 [44%]) or in the vessel lumen and tunica intima (n   7 [39%]).[] Calcifications were most often noted in the tunica media (n   8 [44%]) or in the vessel lumen and tunica intima (n   7 [39%]).[]

  • Dissecting Aortic Aneurysm

    The most important features of dissection in CT are presence of dissection of intima and two lumens, true and false.[] All three tunica layers are involved in true aneurysms (fusiform and saccular). In false aneurysms, blood escapes between tunica layers and they separate.[] The primary tear of the intima was located in the sinus of Valsalva.[]
