Summary
Rasmussen aneurysm, a rare cause of life-threatening hemoptysis, involves a pulmonary artery pseudoaneurysm. This case highlights successful management through coil embolization, emphasizing its importance in differential diagnosis.
Area of Science:
- Cardiology
- Pulmonology
- Interventional Radiology
Background:
- Hemoptysis, or coughing up blood, stems from various pulmonary vascular issues, ranging from minor to life-threatening.
- Rasmussen aneurysm, a specific type of pulmonary artery pseudoaneurysm, is infrequently documented and often overlooked in clinical practice.
Observation:
- A 63-year-old male smoker with no prior lung disease presented with a week of cough and hemoptysis.
- Computed tomography angiography (CTA) revealed a pseudoaneurysm and hemorrhage, indicative of Rasmussen aneurysm.
Findings:
- Pulmonary angiography confirmed the pseudoaneurysm.
- Interventional radiology successfully treated the condition via coil embolization of the tertiary feeding arteries.
Implications:
- This case underscores the successful endovascular management of a rare Rasmussen aneurysm.
- It emphasizes the critical need to include Rasmussen aneurysm in the differential diagnosis for patients presenting with hemoptysis.

10
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

01:17Pulmonary Cycle: Exhalation
1.7K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

218
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

01:24Esophageal Varices-I: Introduction
203
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
