Vasa vasorum

Introduction of Cardiovascular System and Aorta Cardiovascular or circulation system is responsible transportation of hormones, supplying nutrients and oxygen demands of tissues and also waste removal (8). Pulmonary circulation replenishes blood with oxygen and eliminates carbon dioxide within lungs, and systemic circulation delivers blood to all other parts of the body. All systemic circulation begins via aorta, the first blood vessel of the systemic circulation and the largest artery of the body

Classification of aortic dissection: Classification is depends on location since treatment and prognosis relies on upon the part of aorta included. Extent and localization of aortic dissection is classified utilizing the Stanford or DeBakey classification (Geller et al., 2007). Stanford classification: In the Stanford classification, which is generally utilized, type A dissections are dissections including the ascending aorta in regardless to the site of the intimal tear or

enter the latent phase. During the latent phase, the infection is only detectable through serologic testing. Latent or tertiary Disease can be manifested as the gumma (a benign granulomatous lesion), cardiovascular syphilis (usually involving vasa vasorum of the ascending aorta causing an aneurysm), and symptomatic neurosyphilis (which can manifest as symptoms of meningitis) (Fauci, 2012). 2. Differential Diagnosis: • Primary Syphilis: Sexually Transmitted Infections- Genital Herpes, scabies, Chancroid

Elastic tissue is very strong. The adventitia is the outermost layer. It is made of collagen and nourishes the wall with vasa vasorum. An aneurysm is a widening or ballooning of a vessel. It is caused by weakness in the aortic wall. In the aortic wall, the media is mostly affected because it is the thickest. There are instances where dilation of the wall can occur, but to

PATHOLOGICAL CONSIDERATION OF ACUTE CHEST PAIN Chest pain is among the most every now and again assessed introducing complaints in the emergency department (ED). Diagnostic etiologies range from benign to life-debilitating. Inability to diagnose the life-debilitating chest emergencies can prompt to catastrophic medical and legal results for the patient and physician separately (Boie, 2005). The first approach to assessing chest pain incorporates excluding life threatening reasons

Clostridial Aortitis Causing Ruptured Dissecting Aneurysm In A Young Adult Female Introduction Ruptured dissecting aortic aneurysm more commonly occur in men age between 40 to 70 and most commonly associated with atherosclerosis. Other uncommon causes are previous hearts surgery, connective tissue disorder and aortitis.1Infection of the aorta has an overall incidence between 0.7% and 2.6 % with salmonella spp. representing the most commonly identified pathogens. A rare cause of aortic aneurysm is
