Assuming a normal circulation, an embolus formed in a systemic vein will always impact in the lungs, after passing through the right side of the heart. This will form a pulmonary embolism that will result in a blockage of the main artery of the lung and can be a complication of deep-vein thrombosis.
A lung illustration depicting a pulmonary embolism as a thrombus (blood clot) that has travelled from another region of the body, causes occlusion of the pulmonary bronchial artery, leading to arterial thrombosis of the superior and inferior lobes in the left lung: Specialty: Hematology, cardiology, pulmonology, Emergency medicine: Symptoms
FDG-PET study of a 71-year-old woman with a solitary pulmonary nodule (thin arrow) in the left lower lobe near the heart. The scan also revealed abnormal increased activity at the gastro-esophageal junction (thick arrow). The final diagnosis was non-Hodgkin lymphoma at both sites.
Ewart's sign is a set of findings on physical examination in people with large collections of fluid around their heart (pericardial effusions). [2]Dullness to percussion (described historically as "woody" in quality), egophony, and bronchial breath sounds may be appreciated at the inferior angle of the left scapula when the effusion is large enough to compress the left lower lobe of the lung ...
Bronchial Artery Aneurysm: Prevalence, Clinical Characteristics, and Long-Term Prognosis Following Bronchial Artery Embolization - This study is the first original research article on BAA, previously only reported in case reports, investigating the prevalence, characteristics, and long-term prognosis of BAA in BAE cases, showing a prevalence of ...
Lobar pneumonia usually has an acute progression. Classically, the disease has four stages: [1] Congestion in the first 24 hours: This stage is characterized histologically by vascular engorgement, intra-alveolar fluid, and small numbers of neutrophils, often numerous bacteria. Grossly, the lung is heavy and hyperemic.
Other common symptoms are a pulsing noise in the head, progressive weakness, numbness and vision changes as well as debilitating, excruciating pain. [4] [5] In serious cases, blood vessels rupture and cause bleeding within the brain (intracranial hemorrhage). [a] In more than half of patients with AVM, this is the first symptom. [7]
A ventilation/perfusion lung scan, also called a V/Q lung scan, or ventilation/perfusion scintigraphy, is a type of medical imaging using scintigraphy and medical isotopes to evaluate the circulation of air and blood within a patient's lungs, [1] [2] in order to determine the ventilation/perfusion ratio.
