“…The term central PAAs denotes PAAs generated in the left and right main pulmonary arteries from the main pulmonary artery, whereas peripheral PAA denotes PAAs generated from a lobe branch in the periphery. Central PAAs are often secondary to pulmonary hypertension and vasculitis, whereas peripheral PAAs are often secondary to inflammation and trauma associated with arteriosclerosis . In the present patient, we considered the PAA to be idiopathic because he had none of these underlying diseases.…”

“…According to Inaba et al, hemoptysis occurs in only one of 12 patients . In the past, it was recommended that pulmonary aneurysms should be treated as soon as the diagnosis had been made; however, the current recommendation is to resect only very invasive idiopathic peripheral PAAs, especially those considered at relatively high risk of rupture. In such patients, intravascular treatment is less invasive and therefore preferable to surgery.…”

“…In recent years the number of infective aneurysms has decreased with the development of modem antibiotic therapy. The pathogenesis of the intrapulmonary mycotic aneurysms was considered by Ungaro [13] to include at least two of three factors: systemic infection, pulmonary hypertension, and a vascular defect. Despite the aforementioned etiologic factors, no etiologic factor could be determined in this case.…”

“…The right ventricle is frequently enlarged and the ECG reflects the right ventricular hypertrophy in 75% of cases. 2D echocardiographic studies as well as radionuclide angiography can also be used to diagnose the pulmonary artery aneurysm [5][6][7][8][9][10][11][12][13][14][15]. The cause of death is most commonly heart failure or rupture of the aneurysm [1,2,4,16,17].…”

Septic embolism is a relatively common and potentially severe complication of infective endocarditis (IE). Septic emboli (SE), most often described as consisting of a combination of thrombus and infectious material-either bacterial or fungal-can be caused by hematogenous spread from virtually any anatomic site; however, it most commonly originates from cardiac valves. During the past two decades there has been a confluence of various risk factors that, both alone and in combination, led to greater incidence of both IE and SE, including increasing population age, greater use of prosthetic valves, implantation of various intracardiac devices, escalating intravenous drug use, and the high incidence of healthcare associated infections with antibiotic resistant microorganisms. From a clinical standpoint, SE can present at any time during the course of IE and may even be the initial presenting sign. SE may affect virtually any location in the human body, but some organs (e.g., liver, spleen, brain) and anatomic regions (e.g., lower extremity) tend to be more frequently involved. The most important aspect of management involves prompt recognition and proactive therapeutic approach. Given the broad spectrum of clinical presentations, symptoms and complications, SE can be challenging to diagnose and treat. Following the identification of SE, appropriate antibiotic coverage should be immediately instituted followed by supportive and/or interventional management, depending on the severity of presentation and the associated complications. In this chapter we explore the pathophysiology, anatomic origins, diagnostic tools, therapeutic measures, and new developments in SE, focusing predominantly on bacterial infections of cardiac origin.
